Title: Negative photosensitive resin composition, cured film, and organic el display and manufacturing method therefor

Description:
TECHNICAL FIELD 
     The present invention relates to a negative photosensitive resin composition, a cured film, and an organic EL display and a method for manufacturing an organic EL display. 
     BACKGROUND ART 
     In recent years, many products that use organic electroluminescence (hereinafter, “EL”) displays have been developed in display devices including thin displays, such as smartphones, tablet PCs, and televisions. 
     In general, an organic EL display has a transparent electrode such as an indium tin oxide (hereinafter referred to as an “ITO”) on the light-extraction side of a light-emitting element, and a metal electrode such as an alloy of magnesium and silver on the side of the light-emitting element, from which no light is extracted. In addition, in order to define the pixels of the light-emitting element, an insulation layer referred to as a pixel defining layer is formed between the transparent electrode and the metal electrode. After the pixel defining layer is formed, a light-emitting material is deposited by evaporation through an evaporation mask in a region corresponding to the pixel region, where the pixel defining layer has an opening to expose the underlying transparent electrode or metal electrode, thereby forming a light-emitting layer. The transparent electrode and metal electrode are commonly formed by sputtering, but the pixel defining layer requires a low-taper pattern shape in order to prevent disconnection of the formed transparent electrode or metal electrode. 
     Furthermore, the organic EL display has thin-film-transistors (hereinafter, “TFTs”) for controlling the light-emitting element, which include a driving TFT, a switching TFT, and the like formed. In general, these TFTs are formed as laminated structures located further below the transparent electrode or the metal electrode, which serves as a base for the pixel defining layer mentioned above. The level differences due to the TFTs and a TFT array with a metal wiring or the like formed for connecting the TFTs to each other deteriorate uniformity in the subsequent formation of transparent electrodes, metal electrodes, pixel defining layers, and light-emitting layers, thereby causing the display characteristics and reliability of the organic EL display to be deteriorated. For that reason, after forming the TFT array, it is common to form a TFT planarization layer and/or a TFT protective layer for reducing or smoothing the level difference due to the TFT array. 
     Organic EL displays have a self-light-emitting element that emits light with the use of energy generated by recombination of electrons injected from a cathode and holes injected from an anode. Thus, the presence of a substance which inhibits the movement of electrons or holes, a substance that forms an energy level which inhibits recombination of electrons and holes, or the like, makes influences such as the decreased light emission efficiency of the light-emitting element or the deactivation of the light-emitting material, thus leading to the decreased lifetime of the light-emitting element. Since the pixel defining layer is formed at a position adjacent to the light-emitting element, degassing and ionic component outflow from the pixel defining layer can contribute to the decreased lifetime of the organic EL display. For that reason, high heat resistance is required for the pixel defining layer. As photosensitive resin compositions with high heat resistance, negative photosensitive resin compositions are known which include a high heat-resistance polyimide and an oxime ester-based photo initiator (for example, see Patent Document 1). 
     In addition, since the organic EL display has the self-light-emitting element, incident external light such as sunlight outdoors decreases the visibility and contrast due to reflection of the external light. Thus, a technique for reducing external light reflection is required. 
     As a technique for blocking external light and then reducing external light reflection, a photosensitive resin composition containing an alkali-soluble polyimide and a colorant is known (for example, see Patent Document 2). More specifically, there is a method of reducing external light reflection by forming a pixel defining layer with high heat resistance and light-blocking property with the use of a photosensitive resin composition containing a polyimide and a colorant such as a pigment.

     SUMMARY OF THE INVENTION 
     Problems to be Solved by the Invention 
     From the viewpoint of improving the reliability of organic EL displays, in addition to the requirement of high heat resistance for the pixel defining layer adjacent to the light-emitting element, high heat resistance is also required for the TFT planarization layer and the TFT protective layer, because the layers are also formed at positions close to the light-emitting layer with the pixel defining layer interposed therebetween. In the case of containing a colorant such as a pigment in order to impart a light-blocking property to the photosensitive resin composition, however, ultraviolet rays and the like during pattern exposure are also blocked as the content of the colorant is increased, thus decreasing sensitivity for the exposure. Accordingly, conventionally known photosensitive resin compositions containing a colorant all have insufficient characteristics for use as a material for forming pixel defining layers, TFT planarization layers, or TFT protective layers of organic EL displays. Specifically, any of the sensitivity, light-blocking property, or patternability for low-taper shapes has been insufficient. 
     For example, in the case of improving the light-blocking property of the photosensitive resin composition, the deep part of the film is insufficiently cured during pattern exposure, and the deep part of the film is side-etched during development. For that reason, an inverse tapered shape is obtained after the development, which becomes an obstructive factor against the pattern formation in a low-taper shape. On the other hand, sufficient curing down to the deep part of the film, it is necessary to increase the exposure energy for pattern exposure, thereby promoting UV curing. The increased exposure energy makes, however, the film excessively crosslinked during the UV curing, thereby decreasing the reflow property for thermal curing, and thus forming a pattern in a high-taper shape. Accordingly, for example, there has been a problem that the photosensitive resin composition containing an alkali-soluble polyimide and a colorant such as a pigment, described in Patent Document 2, has difficulty in combining characteristics such as sensitivity, light-blocking property, and pattern formation in a low-taper shape. 
     Furthermore, in the case of forming a pattern in a high-taper shape after development and forming a pattern in a low-taper shape by reflow during thermal curing, pattern skirt reflow also caused during the thermal curing. For that reason, the pattern opening width after the thermal curing is smaller as compared with the pattern opening width after development, thus causing an error in the pixel design or the like for a display device such as an organic EL display. In addition, the variation in pattern opening width due to reflow during the thermal curing causes a decrease in panel manufacturing yield. Thus, there has been a problem that it is difficult to achieve a balance between the pattern formation in a low-taper shape and the suppression of the change in pattern opening width between before and after thermal. In order to achieve the balance between the both characteristics, it is necessary to form a pattern in a low-taper shape after development, suppress reflow during thermal curing, and suppress the change in pattern opening width. 
     The present invention has been achieved in view of the foregoing, and an object of the invention is to provide a negative photosensitive resin composition capable of achieving a cured film which is high in sensitivity, capable of forming a pattern in a low-taper shape after development, capable of suppressing the change in pattern opening width between before and after thermal curing, and excellent in light-blocking property. 
     In addition, a further object of the present invention is to provide a cured film which is high in sensitivity, capable of forming a pattern in a low-taper shape after development, capable of suppressing the change in pattern opening width between before and after thermal curing, and excellent in light-blocking property, and an organic EL display.

     &lt;(A1) First Resin&gt; 
     The negative photosensitive resin composition according to the present invention contains at least the (A1) first resin as the (A) alkali-soluble resin. The composition contains, as the (A1) first resin, one or more selected from a (A1-1) polyimide, a (A1-2) polyimide precursor, a (A1-3) polybenzoxazole, and a (A1-4) polybenzoxazole precursor. According to the present invention, the (A1-1) polyimide, the (A1-2) polyimide precursor, the (A1-3) polybenzoxazole, and the (A1-4) polybenzoxazole precursor may be any single resin or copolymer thereof.

     &lt;(A1-1) Polyimide and (A1-2) Polyimide Precursor&gt; 
     Examples of the (A1-2) polyimide precursor include products obtained by reacting a tetracarboxylic acid, a corresponding tetracarboxylic dianhydride or tetracarboxylic diester dichloride, or the like, with a diamine, a corresponding diisocyanate compound or trimethylsilylated diamine, or the like, which have a tetracarboxylic acid residue and/or a derivative residue thereof, and a diamine residue and/or a derivative residue thereof.

     The (A1-2) polyimide precursor, which is a thermosetting resin, is thermally cured at high temperature for dehydration and cyclization to form a highly heat-resistance imide bond, thereby providing the (A1-1) polyimide.

For that reason, the cured film is suitable in such a case of using the cured film for applications which require high heat resistance. In addition, the (A1-2) polyimide precursor, which is a resin with heat resistance improved after dehydration and cyclization, is suitable in such a case of using the precursor for applications which have a desire to achieve a balance between characteristics of the precursor structure before dehydration and cyclization and the heat resistance of the cured film. 
     Furthermore, the (A1-1) polyimide and the (A1-2) polyimide precursor have an imide bond and/or an amide bond as a bond with polarity. For that reason, in the case of containing, in particular, a (D1) pigment as a (D) colorant described later, the bond interacts strongly with the (D1) pigment, thus allowing the dispersion stability of the (D1) pigment to be improved. 
     The (A1-1) polyimide for use in the present invention preferably contains a structural unit represented by the following general formula (1), from the viewpoint of improving the heat resistance of the cured film.

     Examples of the (A1-4) polybenzoxazole precursor include products obtained by reacting a dicarboxylic acid, a corresponding dicarboxylic acid dichloride dicarboxylic acid active diester, or the like with a bisaminophenol compound as a diamine, and which have a dicarboxylic acid residue and/or a derivative residue thereof, and a bisaminophenol compound residue and/or a derivative residue thereof.

     The (A1-4) polybenzoxazole precursor, which is a thermosetting resin, is thermally cured at high temperature for dehydration and cyclization to form a highly heat-resistance and rigid benzoxazole ring, thereby providing the (A1-3) polybenzoxazole. Accordingly, the negative photosensitive resin composition contains therein the (A1-3) polybenzoxazole having the highly heat-resistance and rigid benzoxazole ring, thereby making it possible to remarkably improve the heat resistance of the cured film obtained. For that reason, the cured film is suitable in such a case of using the cured film for applications which require high heat resistance. In addition, the (A1-4) polybenzoxazole precursor, which is a resin with heat resistance improved after dehydration and cyclization, is suitable in such a case of using the precursor for applications which have a desire to achieve a balance between characteristics of the precursor structure before dehydration and cyclization and the heat resistance of the cured film. 
     Furthermore, the (A1-3) polybenzoxazole and the (A1-4) polybenzoxazole precursor have an imide bond and/or an oxazole bond as a bond with polarity. For that reason, in the case of containing, in particular, a (D1) pigment as a (D) colorant described later, the bond interacts strongly with the (D1) pigment, thus allowing the dispersion stability of the (D1) pigment to be improved.

     &lt;Structural Unit Having Fluorine Atom&gt; 
     One or more selected from a (A1-1) polyimide, a (A1-2) polyimide precursor, a (A1-3) polybenzoxazole, and a (A1-4) polybenzoxazole precursor contains a structural unit having a fluorine atom at 10 to 100 mol % of all of the structural units. One or more selected from a (A1-1) polyimide, a (A1-2) polyimide precursor, a (A1-3) polybenzoxazole, and a (A1-4) polybenzoxazole precursor contains a structural unit having a fluorine atom, thereby improving the transparency, allowing the sensitivity for exposure to be improved, and allowing a pattern in a low-taper shape to be formed after development. In addition, halftone characteristics can be improved. This is presumed to be because improved transparency of the film has allowed radical curing in the deep part of the film. In addition, it is believed to be because in a case where the (C1-1) specific oxime ester-based photo initiator described later has a group substituted with a halogen, the compatibility between the resin and the initiator can be increased, thereby causing UV curing during exposure to proceed efficiently even in the deep part of the film. In addition, it is believed to be because fluorine atoms allow water repellency to be imparted to the film surface, thereby making it possible to suppress penetration of the developer into the film surface during alkali development, and suppress side etching by the developer. The exposure herein refers to irradiation with active actinic rays (radiation), and examples thereof include irradiation with visible light, ultraviolet rays, electron beams, X-rays or the like. From the viewpoint of a light source commonly used, for example, an ultra-high pressure mercury lamp light source capable of irradiation with visible light or ultraviolet rays is preferred, and more preferred is irradiation with j-lines (wavelength: 313 nm), i-lines (wavelength: 365 nm), h-lines (wavelength: 405 nm), or g-lines (wavelength: 436 nm). Hereinafter, the exposure refers to irradiation with active actinic rays (radiation). 
     In addition, in general, in the case of using the (A1-1) polyimide, the (A1-2) polyimide precursor, the (A1-3) polybenzoxazole, and/or the (A1-4) polybenzoxazole precursor, it is necessary to use, as an after-mentioned solvent that is used for dissolution of the foregoing resins, a highly polar solvent such as N-methyl-2-pyrrolidone, dimethyl sulfoxide, N,N-dimethylformamide, or γ-butyrolactone. In a case where, in particular, the (D1) pigment is contained as the (D) colorant described later, however, these highly polar solvents interact strongly with the (D1) pigment, and the effect of improving the dispersion stability with the (A1) first resin, the (A2) second resin described layer, or the (E) dispersant described later may be thus insufficient. 
     One or more selected from a (A1-1) polyimide, a (A1-2) polyimide precursor, a (A1-3) polybenzoxazole, and a (A1-4) polybenzoxazole precursor contain a structural unit having a fluorine atom, thereby allowing the solubility in the solvent to be improved. Thus, it is possible to reduce the content of the highly polar solvent described above or dissolve the foregoing resins without using the highly polar solvent, thereby allowing the dispersion stability of the (D1) pigment to be improved.

     Furthermore, in the case of containing, in particular, a (D1a-1a) benzofuranone-based black pigment as the (Da) black colorant described later, a development residue derived from the pigment described above may be generated due to the insufficient alkali resistance of the above-described pigment. In such a case, containing the (B3) flexible chain-containing aliphatic radical polymerizable compound described later and the (B1) fluorene skeleton-containing radical polymerizable compound or (B2) indane skeleton-containing radical polymerizable compound makes it possible to inhibit the development residue generation derived from the pigment described above.

     The (B1) fluorene skeleton-containing radical polymerizable compound and the (B2) indane skeleton-containing radical polymerizable compound can be synthesized by known methods. For example, the synthesis method described in International Publication No. 2008/139924 can be mentioned.

In addition, in the case of containing, in particular, the (D1) pigment as (D) colorant described later, the (D1) pigment is immobilized to the cured part by crosslinking during UV curing of the (B3) flexible chain-containing aliphatic radical polymerizable compound, thus making it possible to inhibit the residue generation after development, which is derived from the (D1) pigment.

     The (B3) flexible chain-containing aliphatic radical polymerizable compound can be synthesized by known methods. 
     The content of the (B3) flexible chain-containing aliphatic radical polymerizable compound in the negative photosensitive resin composition according to the present invention is, in a case where the (A) alkali-soluble resin and the (B) radical polymerizable compound are regarded as 100 parts by mass in total, preferably 5 parts by mass or more, more preferably 10 parts by mass or more, still more preferably 15 parts by mass or more, particularly preferably 20 parts by mass or more.

When the content is 45 parts by mass or less, a cured film in a pattern in a low-taper shape can be obtained. 
     &lt;(B4) Alicyclic Group-Containing Radical Polymerizable Compound&gt; 
     The negative photosensitive resin composition according to the present invention preferably further contains an (B4) alicyclic group-containing radical polymerizable compound as the (B) radical polymerizable compound. The (B4) alicyclic group-containing radical polymerizable compound refers to a compound having a plurality of ethylenically unsaturated double bond groups and an alicyclic group in the molecule. 
     Containing the (B4) alicyclic group-containing radical polymerizable compound allows the change in pattern opening width between before and after thermal curing to be suppressed. This is presumed to be because an alicyclic group is introduced into the film by UV curing during exposure, thereby improving the heat resistance, and suppressing reflow at the pattern skirt. In addition to the foregoing, a forward tapered shape is allowed by pattern shape control after development, and a pattern in a low-taper shape can be formed after thermal curing. This is presumed to be because the hydrophobicity of the alicyclic group blocks the penetration of the alkaline developer into the film during development, and because the steric hindrance of the alicyclic group inhibits excessive curing during thermal curing. 
     The negative photosensitive resin composition according to the present invention preferably contains the (B4) alicyclic group-containing radical polymerizable compound and a (F) polyfunctional thiol compound to be described later. The (B4) alicyclic group-containing radical polymerizable compound and the (F) polyfunctional thiol compound are used in combination, thereby making it possible to suppress the change in pattern opening width between before and after thermal curing, and making it possible to form a pattern in a low-taper shape after development. This is believed to be because the (F) polyfunctional thiol compound suppresses oxygen inhibition at the film surface, thereby promoting the UV curing of the (B4) alicyclic group-containing radical polymerizable compound during exposure. More specifically, it is presumed that the heat resistance and hydrophobicity derived from the alicyclic group are improved by the UV curing during exposure. This is believed to be because UV curing is remarkably promoted by the use of the (F) polyfunctional thiol compound in combination, since the (B4) alicyclic group-containing radical polymerizable compound is likely to undergo UV curing inhibited due to the steric hindrance of the alicyclic group in addition to oxygen inhibition at the film surface. 
     The number of ethylenically unsaturated double bond groups in the molecule of the (B4) alicyclic group-containing radical polymerizable compound is more preferably 2 or more, still more preferably 3 or more. When the number of ethylenically unsaturated double bond groups is 2 or more, the sensitivity for exposure can be improved. On the other hand, the number of ethylenically unsaturated double bond groups in the molecule of the (B4) alicyclic group-containing radical polymerizable compound is preferably 10 or less, more preferably 6 or less. When the number of ethylenically unsaturated double bond groups is 10 or less, a pattern in a low-taper shape can be formed after thermal curing. 
     The alicyclic group in the molecule of the (B4) alicyclic group-containing radical polymerizable compound is preferably a polycyclic condensed alicyclic skeleton. Having the polycyclic condensed alicyclic skeleton allows the change in pattern opening width between before and after thermal curing to be suppressed. In addition, a forward tapered shape is allowed by pattern shape control after development, and a pattern in a low-taper shape can be formed after thermal curing. 
     Examples of the polycyclic condensed alicyclic skeleton include a bicyclo[4.3.0]nonane skeleton, a bicyclo[5.4.0]undecane skeleton, a bicyclo[2.2.2]octane skeleton, a tricyclo[5.2.1.0 2,6 ]decane skeleton, a pentacyclopentadecane skeleton, an adamantane skeleton, or a hydroxyadamantane skeleton. 
     Examples of the (B4) alicyclic group-containing radical polymerizable compound include dimethylol-bicyclo[4.3.0]nonane (meth)acrylate, dimethylol-bicyclo[5.4.0]undecane di(meth)acrylate, dimethylol-bicyclo[2.2.2]octane di(meth)acrylate, dimethylol-tricyclo[5.2.1.0 2,6 ]decane di(meth)acrylate, dimethylol-pentacyclopentadecane di(meth)acrylate, 1,3-adamantane di(meth)acrylate, 1,3,5-adamantane tri(meth)acrylate, or 5-hydroxy-1,3-adamantane di(meth)acrylate. 
     The (B4) alicyclic group-containing radical polymerizable compound can be synthesized by known methods. 
     The content of the (B4) alicyclic group-containing radical polymerizable compound in the negative photosensitive resin composition according to the present invention is, in a case where the (A) alkali-soluble resin and the (B) radical polymerizable compound are regarded as 100 parts by mass in total, preferably 1 part by mass or more, more preferably 2 parts by mass or more, still more preferably 3 parts by mass or more, even more preferably 5 parts by mass or more, particularly preferably 10 parts by mass or more. When the content is 1 part by mass or more, the change in pattern opening width between before and after thermal curing can be suppressed. Furthermore, a forward tapered shape is allowed by pattern shape control after development, and a pattern in a low-taper shape can be formed after thermal curing. On the other hand, the content of the (B4) alicyclic group-containing radical polymerizable compound is preferably 30 parts by mass or less, more preferably 27 parts by mass or less, still more preferably 25 parts by mass or less, even more preferably 22 parts by mass or less, particularly preferably 20 part by mass or less. When the content is 30 parts by mass or less, the change in pattern opening width between before and after thermal curing can be suppressed, and the residue generation after development can be inhibited. 
     &lt;(C1) Photo Initiator&gt; 
     The negative photosensitive resin composition according to the present invention further contains the (C1) photo initiator as the (C) photosensitive agent. The (C1) photo initiator refers to a compound that generates radicals through bond cleavage and/or reaction upon exposure. Containing the (C1) photo initiator causes radical polymerization of the above-described (B) radical polymerizable compound to proceed, thereby making the exposed part of the film of the resin composition insoluble in an alkaline developer, and then allowing a negative pattern to be formed. In addition, UV curing during the exposure is accelerated, thereby allowing the sensitivity to be improved. 
     Further, containing a specific amount of (C1) photo initiator or more allows the change in pattern opening width between before and after thermal curing to be suppressed. This is believed to be due to an increase in radical generation, derived from the (C1) photo initiator during the exposure. More specifically, increasing the radical generation during the exposure is presumed to increase the probability of collision between the generated radicals and the ethylenically unsaturated double bond group in the above-described (B) radical polymerizable compound, thereby accelerating UV curing and then improving the crosslink density, thus suppressing reflow of a pattern taper and a pattern skirt during thermal curing, and thus making it possible to suppress the change in pattern opening width between before and after thermal curing.

Furthermore, R 29  preferably represents, from the viewpoint of improving the sensitivity for exposure and forming a pattern in a low-taper shape after development, a haloalkyl group having 1 to 10 carbon atoms, a haloalkoxy group having 1 to 10 carbon atoms, a heterocyclic ring group having 4 to 10 carbon atoms, a heterocyclic oxy group having 4 to 10 carbon atoms, an acyl group having 2 to 10 carbon atoms, or a nitro group. R 30  preferably represents hydrogen or an alkyl group having 1 to 10 carbon atoms, more preferably hydrogen or an alkyl group having 1 to 4 carbon atoms, still more preferably methyl, from the viewpoint of improving the sensitivity for exposure. a preferably represents 0 from the viewpoint of improving the sensitivity for exposure. 
     The group represented by the general formula (11) is a group having an oxime ester structure, which is a group having a structure that generates a radical through a bond cleavage and/or a reaction by UV for exposure. It is to be noted that the fluorene structure, carbazole structure, dibenzofuran structure, dibenzothiophene structure, naphthalene structure, diphenylmethane structure, diphenylamine structure, diphenyl ether structure, or diphenyl sulfide structure in the above-described (II) or (III) represents a mother skeleton to which the above-described group having the oxime ester structure is bonded. In addition, the naphthalenecarbonyl structure, trimethylbenzoyl structure, thiophenecarbonyl structure, furancarbonyl structure, and nitro group in the above-described (I), (II), or (III) represent a structure or a group that is bonded to the mother skeleton to which the above-described group having the oxime ester structure is bonded. 
     The (C1-1) specific oxime ester-based photo initiator an oxime ester-based compound having, in the molecule, a specific conjugated structure which increases the absorbance in the ultraviolet area to allow for the promotion of radical curing in the deep part of the film during exposure and radical curing by the increased radical generation during exposure. 
     Containing the (C1-1) specific oxime ester-based photo initiator allows the sensitivity for exposure to be improved, and allows a pattern in a low-taper shape to be formed after development. In addition, halftone characteristics can be improved. This is presumed to be because radical curing is allowed in the deep part of the film during exposure. In addition, it is believed to be because the specific conjugated structure of the (C1-1) specific oxime ester-based photo initiator interacts with the aromatic groups of the (A1) first resin and (A2) second resin to make the entire film compatible, while the promotion of radical curing into the deep part of the film by the increased radical generation during exposure suppresses the penetration of the developer into the cured film during alkali development, thereby allowing side etching with the developer to be suppressed. 
     Further, containing the (C1-1) specific oxime ester-based photo initiator allows the change in pattern opening width between before and after thermal curing to be suppressed. This is presumed to be because in addition to the suppression of side etching by the developer during alkali development, which allows the pattern formation in a low-taper shape after development, in the same manner as described above, UV curing during exposure is promoted, thereby increasing the molecular weight of the cured film, and then suppressing reflow of the pattern skirt during thermal curing. 
     The (C1-1) specific oxime ester-based photo initiator preferably contains, from the viewpoints of improving the sensitivity for exposure, reducing the taper by pattern shape control after development, suppressing the change in pattern opening width between before and after thermal curing, and improving the halftone characteristics, one or more selected from the group consisting of a compound represented by the general formula (12), a compound represented by the general formula (13), and a compound represented by the general formula (14), more preferably a compound represented by the general formula (13).

     Furthermore, the (C1-1) specific oxime ester-based photo initiator preferably contains, from the viewpoints of improving the sensitivity for exposure, reducing the taper by pattern shape control after development, suppressing the change in pattern opening width between before and after thermal curing, and improving the halftone characteristics, a compound represented by the general formula (12) and/or a compound represented by the general formula (13).

     The (C1-1) specific oxime ester-based photo initiator preferably has a halogen-substituted group. The (C1-1) specific oxime ester-based photo initiator has the halogen-substituted group, thereby improving the solubility in a solvent. In addition, the compatibility with the (A1) first resin and the (A2) second resin is improved, thereby allowing the sensitivity for exposure to be improved, and allowing a pattern in a low-taper shape to be formed after development. In addition, the change in pattern opening width between before and after thermal curing can be suppressed, and the halftone characteristics can be improved. As the halogen, fluorine is preferred. This is believed to be because in a case where the (C1-1) specific oxime ester-based photo initiator has a fluorine-substituted group, one or more selected from the (A1-1) polyimide, the (A1-2) polyimide precursor, the (A1-3) polybenzoxazole, and the (A1-4) polybenzoxazole precursor as the (A1) first resin contain a structural unit having a fluorine atom, thus allowing the compatibility between the resin and the initiator to be further enhanced, and then causing V curing during exposure to proceed efficiently even in the deep part of the film.

     The (C1-1) specific oxime ester-based photo initiator can be synthesized by known methods. The methods include the synthesis methods described in JP 2013-190459 A, JP 2016-191905 A, and International Publication No. 2014/500852. 
     The maximum absorption wavelength of the (C1-1) specific oxime ester-based photo initiator is preferably 330 nm or more, more preferably 340 nm or more, still more preferably 350 nm or more. When the maximum absorption wavelength is 330 nm or more, the sensitivity for exposure can be improved, and a pattern in a low-taper shape can be formed after development. In addition, the change in pattern opening width between before and after thermal curing can be suppressed, and the halftone characteristics can be improved. On the other hand, the maximum absorption wavelength of the (C1-1) specific oxime ester-based photo initiator is preferably 410 nm or less, more preferably 400 nm or less, still more preferably 390 nm or less, particularly preferably 380 nm or less. When the maximum absorption wavelength is 410 nm or less, the sensitivity for exposure can be improved, and a pattern in a low-taper shape can be formed after development. In addition, the change in pattern opening width between before and after thermal curing can be suppressed, and the halftone characteristics can be improved. 
     Furthermore, in a case where the maximum transmission wavelength of the (Da) black colorant described later is 330 to 410 nm, when the maximum absorption wavelength of the (C1-1) specific oxime ester-based photo initiator is 330 to 410 nm, the sensitivity for exposure can be improved, and a pattern in a low-taper shape can be formed after development. In addition, the change in pattern opening width between before and after thermal curing can be suppressed, and the halftone characteristics can be improved. This is believed to be because UV light for exposure is capable of reaching the deep part of the film, thus causing UV curing to proceed efficiently even in the deep part of the film. 
     It is to be noted that the maximum absorption wavelength and the maximum transmission wavelength respectively refer to a wavelength at which the maximum absorption is exhibited and a wavelength at which the maximum transmission is exhibited in the absorption spectrum and transmission spectrum within a wavelength range of 300 to 800 nm. 
     The absorbance at a wavelength of 360 nm in a 0.01 g/L propylene glycol monomethyl ether acetate solution of the (C1-1) specific oxime ester-based photo initiator is preferably 0.20 or more, more preferably 0.25 or more, still more preferably 0.30 or more, even more preferably 0.35 or more, particularly preferably 0.40 or more, most preferably 0.45 or more. When the absorbance is 0.20 or more, the sensitivity for exposure can be improved, and a pattern in a low-taper shape can be formed after development. In addition, the change in pattern opening width between before and after thermal curing can be suppressed, and the halftone characteristics can be improved. On the other hand, the absorbance at a wavelength of 360 nm in a 0.01 g/L propylene glycol monomethyl ether acetate solution of the (C1-1) specific oxime ester-based photo initiator is preferably 1.00 or less. When the absorbance is 1.00 or less, the residue generation after development can be inhibited, and the resolution after development can be improved. 
     The content of the (C1-1) specific oxime ester-based photo initiator in the negative photosensitive resin composition according to the present invention is, in a case where the (A) alkali-soluble resin and the (B) radical polymerizable compound are regarded as 100 parts by mass in total, preferably 0.1 parts by mass or more, more preferably 0.5 parts by mass or more, still more preferably 0.7 parts by mass or more, particularly preferably 1 part by mass or more. When the content is 0.5 parts by mass or more, the sensitivity for exposure can be improved. Furthermore, the content of the (C1-1) specific oxime ester-based photo initiator is, from the viewpoint of pattern shape control after development and after thermal curing, preferably 3 parts by mass or more, more preferably 4 parts by mass or more, still more preferably 5 parts by mass or more, particularly preferably 7 parts by mass or more. When the content is 3 parts by mass or more, a pattern in a low-taper shape can be formed after development, and the change in pattern opening width between before and after thermal curing can be suppressed. In addition, halftone characteristics can be improved. On the other hand, the content of the (C1-1) specific oxime ester-based photo initiator is preferably 25 parts by mass or less, more preferably 22 parts by mass or less, still more preferably 20 parts by mass or less, particularly preferably 15 parts by mass or less. When the content is 25 parts by mass or less, the resolution after development can be improved, and a cured film with a pattern in a low-taper shape can be obtained. Furthermore, the content of the (C1-1) specific oxime ester-based photo initiator is, from the viewpoint of pattern shape control after development, preferably 20 parts by mass or less, more preferably 17 parts by mass or less, still more preferably 15 parts by mass or less, particularly preferably 13 parts by mass or less. When the content is 20 parts by mass or less, a pattern in a low-taper shape can be formed after development, and the change in pattern opening width between before and after thermal curing can be suppressed. 
     &lt;(C1-2) α-Aminoketone-Based Photo Initiator, (C1-3) Acylphosphine Oxide-Based Photo Initiator, and (C1-4) Biimidazole-Based Photo Initiator&gt; 
     The negative photosensitive resin composition according to the present invention preferably further contains, as the (C1) photo initiator, one or more selected from the group consisting of the (C1-2) α-aminoketone-based photo initiator, the (C1-3) acylphosphine oxide-based photo initiator, and the (C1-4) biimidazole photo initiator. 
     Containing one or more selected from the group consisting of the (C1-2) α-aminoketone-based photo initiator, the (C1-3) acylphosphine oxide-based photo initiator, and the (C1-4) biimidazole photo initiator allows the sensitivity for exposure to be improved. This is believed to be because these photo initiators have an absorption wavelength in a wavelength region that is different from the absorption wavelength of the above-described (C1-1) specific oxime ester-based photo initiator, thereby allowing UV light for exposure to be more efficiently used for radical curing. In addition to the foregoing, the change in pattern opening width between before and after thermal curing can be suppressed. This is presumed to be for the following reason, in addition to radical curing proceeding more efficiently depending on the difference in absorption wavelength as well. It is believed that since the (C1-2) α-aminoketone-based photo initiator, the (C1-3) acylphosphine oxide-based photo initiator, and the (C1-4) biimidazole-based photo initiator contain nitrogen or phosphorus in the molecules, amine or phosphine is produced by photolysis during exposure and/or thermal decomposition during thermal curing, and these products act as a cross-linking catalyst during thermal curing, thereby suppressing reflow at the pattern skirt. 
     In the negative photosensitive resin composition according to the present invention, the content ratio of the (C1-1) specific oxime ester-based photo initiator in the (C1) photo initiator is preferably 55% by mass or higher, more preferably 60% by mass or higher, still more preferably 65% by mass or higher, even more preferably 70% by mass or higher, particularly preferably 75% by mass or higher. When the content ratio is 55% by mass or higher, the sensitivity for exposure can be improved, and the change in pattern opening width between before and after thermal curing can be suppressed. On the other hand, the content ratio of the (C1-1) specific oxime ester-based photo initiator is preferably 95% by mass or lower, more preferably 93% by mass or lower, still more preferably 90% by mass or lower, still more preferably 88% by mass or lower, particularly preferably 85% by mass or lower. When the content ratio is 95% by mass or lower, the sensitivity for exposure can be improved, and the change in pattern opening width between before and after thermal curing can be suppressed. 
     In the negative photosensitive resin composition according to the present invention, the total content ratio of the (C1-2) α-aminoketone-based photo initiator, (C1-3) acylphosphine oxide-based photo initiator, and (C1-4) biimidazole-based photo initiator in the (C1) photo initiator is preferably 5% by mass or higher, more preferably 7% by mass or higher, still more preferably 10% by mass or higher, even more preferably 12% by mass or higher, particularly preferably 15% by mass or higher. When the content ratio is 5% by mass or higher, the sensitivity for exposure can be improved, and the change in pattern opening width between before and after thermal curing can be suppressed. On the other hand, the content ratio of the (C1-1) specific oxime ester-based photo initiator is preferably 45% by mass or lower, more preferably 40% by mass or lower, still more preferably 35% by mass or lower, even more preferably 30% by mass or lower, particularly preferably 25% by mass or lower. When the content ratio is 45%. by mass or lower, the sensitivity for exposure can be improved, and the change in pattern opening width between before and after thermal curing can be suppressed. 
     &lt;(C2) Photo Acid Generator&gt; 
     The negative photosensitive resin composition according to the present invention may further contain a (C2) photo acid generator as the (C) photosensitive agent. The (C2) photo acid generator refers to a compound that causes bond cleavage upon exposure to generate an acid. Containing the (C2) photo acid generator accelerates UV curing during the exposure, allowing the sensitivity to be improved. Furthermore, the crosslink density after thermal curing of the resin composition is improved, thereby allowing the chemical resistance of the cured film to be improved. Examples of the (C2) photo acid generator include ionic compounds and non-ionic compounds. 
     As the (C2) photo acid generator of an ionic compound, compounds containing no heavy metal or halogen ion are preferred, and triorganosulfonium salt-based compounds are more preferred.

Among these (C2) photo acid generators, the non-ionic compounds are more preferred than the ionic compounds from the viewpoints of the solubility and the insulation properties of the cured film. From the viewpoint of the strength of the acid generated, those that generate benzenesulfonic acid, 4-toluenesulfonic acid, perfluoroalkylsulfonic acid, or phosphoric acid are more preferred.

The colorant (D) refers to a compound that absorbs light of a specific wavelength, in particular, a compound which is colored by absorbing light with a wavelength of visible light (380 to 780 nm). Containing the (D) colorant makes it possible to color a film obtained from the negative photosensitive resin composition, and makes it possible to impart colorability of coloring the light transmitted through the resin composition film or the light reflected from the resin composition film into a desired color. Furthermore, it is possible to impart a light-blocking property of blocking light with a wavelength absorbed by the (D) colorant, from light transmitted through the resin composition film or light reflected from the resin composition film. 
     Examples of the colorant (D) include compounds that absorb light with a wavelength of visible light and are colored in red, orange, yellow, green, blue, or purple.

     The negative photosensitive resin composition according to the present invention contains, as the (D) colorant, the (Da) black colorant as an essential component. The (Da) black colorant refers to a compound which is colored in black by absorbing light with a wavelength of visible light. Containing the (Da) black colorant makes it possible to improve the light blocking property of blocking the light transmitted through the resin composition film or the light reflected from the resin composition film, because the resin composition film is blackened.

A resin composition containing at least an arbitrary binder resin and the (D) colorant is prepared such that the content ratio of the (D) colorant in the total solid content of the resin composition is 35% by mass. After a film of the resin composition is applied onto a Tempax glass substrate (manufactured by AGC TECHNO GLASS CO., LTD.), the film is prebaked at 110° C. for 2 minutes to form a film, thereby providing a prebaked film. Next, with the use of a high-temperature inert gas oven (INH-9CD-S; manufactured by Koyo Thermo Systems Co., Ltd.), the film is subjected to thermal curing at 250° C. for 60 minutes under a nitrogen atmosphere, thereby preparing a cured film of 1.0 μm in film thickness from the resin composition containing the (D) colorant (hereinafter, “colorant-containing cured film”). In addition, a resin composition containing the binder resin and containing no (D) colorant is prepared, and applied onto a Tempax glass substrate, and prebaked and subjected to thermal curing by the same manner as mentioned above, thereby preparing a cured film of 1.0 μm in film thickness from the resin composition containing no (D) colorant (hereinafter, a “blank cured film”.

Next, the Tempax glass substrate with the prepared colorant-containing cured film formed is measured with a single beam, thereby measuring the transmittance per 1.0 μm of the film thickness at a wavelength of 450 to 650 nm, and calculating the transmittance of the colorant-containing cured film from the difference from the blank. 
     As the (Da) black colorant, a compound which is colored in black by absorbing light of all wavelengths of visible light is preferred from the viewpoint of the light-blocking property. Also preferred is a mixture of two or more (D) colorants selected from red, orange, yellow, green, blue, or purple colorants.

     Containing one or more selected from the group consisting of the (D1a-1a) benzofuranone-based black pigment, the (D1a-1b) perylene-based black pigment, and the (D1a-1c) azo-based black pigment makes the resin composition film blackened, and provides excellent hiding power, thus allowing the light-blocking property of the resin composition film to be improved. In particular, as compared with common organic pigments, the light-blocking property per unit content ratio of the pigment in the resin composition is excellent, thus allowing the same light-blocking property to be imparted with a low content ratio. Accordingly, the light-blocking property of the film can be improved, and the sensitivity for exposure can be improved. Furthermore, since the pigment is an organic substance, the chemical structure change or functionality transformation adjusts the transmission spectrum or absorption spectrum of the resin composition film, such as transmitting or blocking light with a desired specific wavelength, thereby making it possible to improve the toning property. In particular, since the transmittance of wavelengths in the near-infrared area (for example, 700 nm or more) can be improved, the composition has a light-blocking property, and the composition is suitable for applications which use light with wavelengths in the near-infrared area. Moreover, as compared with common organic pigments and inorganic pigments, the pigment is excellent in insulation properties and low dielectric properties, the resistance value of a film can be improved. In particular, in the case of use as an insulation layer such as a pixel defining layer of an organic EL display, a TFT planarization layer, or a TFT protective layer, defective light emissions can be suppressed, thereby improving reliability. 
     In addition, the (D1a-1a) benzofuranone-based black pigment absorbs light with a wavelength of visible light, and at the same time, has a high transmittance for wavelengths in the ultraviolet area (for example, 400 nm or less), and thus, containing the (D1a-1a) benzofuranone-based black pigment allows the sensitivity for exposure to be improved, and allows a pattern in a low-taper shape to be formed after development. 
     On the other hand, in the case of containing a (D1a-1a) benzofuranone-based black pigment, a development residue derived from the pigment described above may be generated due to the insufficient alkali resistance of the pigment as described above. More specifically, when the surface of the (D1a-1a) benzofuranone-based black pigment described above is exposed to an alkaline developer during development, a part of the surface may be decomposed or dissolved, thereby remaining on the substrate as a development residue derived from the pigment described above. In such a case, as described above, containing the (B3) flexible chain-containing aliphatic radical polymerizable compound and the (B1) fluorene skeleton-containing radical polymerizable compound or (B2) indane skeleton-containing radical polymerizable compound makes it possible to inhibit the development residue generation derived from the pigment described above. 
     The (D1a-1a) benzofuranone-based black pigment refers to a compound with a benzofuran-2(3H)-one structure or a benzofuran-3(2H)-one structure in the molecule, which is colored in black by absorbing light with a wavelength of visible light. The (D1a-1a) benzofuranone-based black pigment is preferably a benzofuranone compound represented by any of the general formulas (63) to (68), a geometric isomer thereof, a salt thereof, or a salt of the geometric isomer.

In addition, the change in pattern opening width between before and after thermal curing can be suppressed, and the halftone characteristics can be improved. In addition, since the transmittance of wavelengths in the near-infrared area can be improved, the composition has a light-blocking property, and the composition is suitable for applications which use light with wavelengths in the near-infrared area.

     When the (D1a-3) pigment mixture of two or more colors is composed as described above, the pigment has excellent alkali resistance, thus suppressing the decomposition or dissolution of the pigment surface during alkali development, and allowing the development residue generation due to the pigment to be inhibited. Furthermore, the pigment has excellent heat resistance, and the halogen content derived from the pigment in the resin composition can be reduced, thereby providing excellent insulation properties and low dielectric properties. Thus, the resistance value of the film can be improved.

When the content ratio is 70% by mass or lower, the sensitivity for exposure can be improved. 
     &lt;(DC) Covering Layer&gt; 
     As the negative photosensitive resin composition according to the present invention, the (D1a-1) black organic pigment preferably further contains a (DC) covering layer. The (DC) covering layer refers to a layer covering a pigment surface, which is formed by a treatment such as a surface treatment with a silane coupling agent, a surface treatment with a silicate, a surface treatment with a metal alkoxide, or a covering treatment with a resin, for example. 
     Containing the (DC) covering layer makes it possible to modify the surface condition of the particles, such as acidifying or basifying the particle surfaces of the (D1a-1) black organic pigment or making the particle surfaces hydrophilic or hydrophobic, and then makes it possible to improve the acid resistance, the alkali resistance, the solvent resistance, the dispersion stability, the heat resistance, and the like. Thus, the development residue generation derived from a pigment can be inhibited. In addition, side etching during development is suppressed, a pattern in a low-taper shape can be formed after development, and reflow of the pattern skirt during thermal curing is suppressed, and thus, the change in pattern opening width between before and after thermal curing can be suppressed. In addition, since it is possible to form a pattern in a low-taper shape by controlling the pattern shape after development, the halftone characteristics can be improved. In addition, an insulating covering layer is formed on the particle surfaces to improve the insulation properties of the cured film for reduction in leakage current and the like, thereby allowing display reliability and the like to be improved. 
     In the case of containing, in particular, the (D1a-1a) benzofuranone-based black pigment as the (D1a-1) black organic pigment, the (D1a-1a) benzofuranone-based black pigment contains therein the (DC) covering layer, thereby allowing the alkali resistance of the pigment to be improved, and then allowing the development residue generation derived from the pigment to be inhibited. 
     The average coverage of the (DC) covering layer with respect to the (D1a-1) black organic pigment is preferably 50% or higher, preferably 70% or higher, more preferably 80% or higher, still more preferably 90% or higher. When the average coverage of the (DC) covering layer is 80% or higher, the residue generation during development can be inhibited. 
     For the average coverage of the (DC) covering layer with respect to the (D1a-1) black organic pigment, a cross section is observed at a magnification of 50,000 to 200,000 times under the condition of an acceleration voltage of 300 kV with the use of a transmission electron microscope (H9500; manufactured by Hitachi High-Technologies Corporation), and for 100 black pigment particles randomly selected, the average coverage N (%) can be determined by determining the coverage M (%) for each black pigment from the following formula, and calculating the number average value. 
       Coverage  M  (%)={ L 1/( L 1+ L 2)}×100
 
     L1: the total length (nm) of a site of the outer periphery of a particle, covered with the covering layer 
     L2: the total length (nm) of a site of the outer periphery of the particle, covered with no covering layer (the site with the interface and the embedded resin in direct contact) 
     L1+L2: the outer peripheral length (nm) of a particle 
     &lt;(DC-1) Silica Covering Layer, (DC-2) Metal Oxide Covering Layer, and (DC-3) Metal Hydroxide Covering Layer&gt; 
     The (DC) covering layer preferably contains one selected from the group consisting of a (DC-1) silica covering layer, a (DC-2) metal oxide covering layer, and a (DC-3) metal hydroxide covering layer. The silica, the metal oxide, and the metal hydroxide have the function of imparting alkali resistance to the pigment, thus the development residue generation derived from the pigment to be inhibited. 
     The silica included in the (DC-1) silica covering layer refers to a general term for silicon dioxide and hydrates thereof. The metal oxide included in the (DC-2) metal oxide covering layer refers to a general term for metal oxides and hydrates thereof. Examples of the metal oxide include alumina as an example, and include alumina (Al 2 O 3 ) or an alumina hydrate (Al 2 O 3 .nH 2 O), for example. Examples of the metal hydroxide contained in the (DC-3) metal hydroxide covering layer include an aluminum hydroxide (Al(OH) 3 ). Because silica has a low dielectric constant, the dielectric constant of the pixel defining layer can be kept from being increased, even in a case where the content of the (DC) covering layer of the (D1a-1) black organic pigment is high. 
     The (DC-1) silica covering layer, (DC-2) metal oxide covering layer, and (DC-3) metal hydroxide covering layer of the (DC) covering layer can be analyzed by, for example, an X-ray diffraction method. Examples of the X-ray diffractometer include a powder X-ray diffractometer (manufactured by Mac Science). The mass of the silicon atoms or metal atoms contained in the (DC-1) silica covering layer, (DC-2) metal oxide covering layer, and (DC-3) metal hydroxide covering layer is rounded to one decimal place to calculate the value down to the first decimal place. In addition, the mass of the pigment particles, excluding the (DC) covering layer, contained in the (D1a-1) black organic pigment including the (DC) covering layer can be determined by the following method, for example. After the operation of putting the pigment with the mass measured in a mortar, grinding the pigment with a pestle for the removal of the (DC) covering layer, then dissolving only the pigment particles by immersion in an amide-based solvent such as N,N-dimethylformamide, and removing the particles as filtrate, is repeated until the filter cake completely loses the blackness, the mass of the filter cake is measured, and the mass of the pigment particles is calculated from the difference from the pigment mass. 
     The metal oxide or metal hydroxide contained in the (DC-2) metal oxide covering layer or (DC-3) metal hydroxide covering layer preferably has both chemical durability such as alkali resistance, heat resistance and light resistance, and physical durability such as Vickers hardness that can withstand mechanical energy input appropriately optimized in the dispersion step, and wear resistance. Examples of the metal oxide and metal hydroxide include alumina, zirconia, zinc oxides, titanium oxides, and ferric oxides. Alumina or zirconia is preferred from the viewpoint of insulation properties, and ultraviolet transmittance and near-infrared transmittance, and alumina is more preferred from the viewpoint of dispersibility in alkali-soluble resins and solvents. The metal oxide and the metal hydroxide may be surface-modified with a group including an organic group. 
     In a case where the (DC) covering layer contains the (DC-1) silica covering layer, an alumina covering layer is formed as the (DC-2) metal oxide covering layer on the surface of the (DC-1) silica covering layer, thereby a decrease in pattern linearity to be suppressed. Since alumina is effective for dispersibility improvement in an aqueous pigment suspension even in the pigment granulation step performed after the pigment surface treatment step, the secondary aggregation particle diameter can be adjusted to a desired range, and furthermore, the productivity and quality stability can be improved. As the (DC-2) metal oxide covering layer contained in the (DC) covering layer, the covering amount of the alumina covering layer is preferably 10 parts by mess or more, more preferably 20 parts by weight or more, in a case where the silica contained in the (DC-1) silica covering layer is regarded as 100 parts by mass. 
     In the case of the (DC) covering layer containing the (DC-1) silica covering layer, the silica content is preferably 1 part by mass or more, more preferably 2 parts by mass or more, still more preferably 5 parts by mass or more, in a case where the pigment particles are regarded as 100 parts by mass. The content is adjusted to 1 part by mass or more, thereby making it possible to increase the coverage on the pigment particle surface and inhibit the development residue generation derived from the pigment. On the other hand, the content of the silica is preferably 20 parts by mass or less, more preferably 10 parts by mass or less. The content is adjusted to 20 parts by mass or less, thereby allowing the pattern linearity of the pixel defining layer to be improved. 
     In the case of the (DC) covering layer containing the (DC-2) metal oxide covering layer and/or the (DC-3) metal hydroxide covering layer, the total content of metal oxide and metal hydroxide is preferably 0.1 parts by mass or more, more preferably 0.5 parts by mass or more, in a case where the pigment particles are regarded as 100 parts by mass. The total content is adjusted to 0.1 parts by mass or more, the dispersibility and the pattern linearity can be improved. On the other hand, the total content of the metal oxide and metal hydroxide is preferably 15 parts by mass or less, more preferably 10 parts by mass or less. The total content is adjusted to 15 parts by mass or less, thereby making it possible to keep the concentration gradient of the pigment from being generated, and improve the storage stability of the coating liquid, in the photosensitive composition according to the present invention, which is designed to make the viscosity lower, preferably, provide a viscosity of 15 mPa s or lower. 
     It is to be noted that the content of the silica refers to the silicon dioxide equivalent value calculated from the content of silicon atoms, which refers to a SiO 2  equivalent value, including cases where there is not only a single component in the (DC) covering layer and at the surface layer, and cases where the amount of dehydration varies due to thermal history. The contents of the metal oxide and metal hydroxide refer to the metal oxide and metal hydroxide equivalent values calculated from the metal atom content. More specifically, in the case of alumina, zirconia, and titanium oxide, the contents respectively refer to an Al 2 O 3  equivalent value, a ZrO 2  equivalent value, and a TiO 2  equivalent value. In addition, the total content of the metal oxide and metal hydroxide refers to the content in the case of containing either the metal oxide or the metal hydroxide, or refers to the total content in the case of containing the both. 
     The (DC) covering layer may be surface-modified with an organic group by using a silane coupling agent, with, as a reactive site, hydroxy at the surface of the silica, metal oxide, or metal hydroxide contained in the (DC-1) silica covering layer, (DC-2) metal oxide covering layer, or (DC-3) metal hydroxide covering layer. As the organic group, an ethylenically unsaturated double bond group is preferred. The surface modification with a silane coupling agent having an ethylenically unsaturated double bond group is capable of imparting radical polymerizability to the (D1a-1) black organic pigment, and suppressing film peeling at the cured part, thereby inhibiting the development residue generation derived from the pigment at the unexposed part. 
     As the (D1a-1) black organic pigment including the (DC) covering layer, the outermost layer may be further subjected to a surface treatment with an organic surface treatment agent. The outermost layer is subjected to the surface treatment, thereby allowing the wettability to the resin or the solvent to be improved. The (DC) covering layer may further contain a resin covering layer formed by a covering treatment with a resin. Containing the resin covering layer provides particle surfaces covered with an insulating resin with low conductivity, thereby allowing the particle surface condition to be modified, and allowing the light-blocking and insulating properties of the cured film to be improved. 
     &lt;(D2) Dye&gt; 
     In the negative photosensitive resin composition according to the present invention, the above-mentioned (D) colorant preferably contains a (D2) pigment. As an aspect in which the (D) colorant described above contains the (D2) dye, it is preferable to contain the (D2) dye as the colorant other than the (Da) black colorant and/or (Db) non-black colorant described above. 
     The (D2) dye refers to a compound that colors an object by chemical adsorption or strong interaction of a substituent such as an ionic group or a hydroxy group in the (D2) dye on or with the surface structure of the object, and the compound is typically soluble in solvents and the like. In addition, coloring with the (D2) dye is high in coloring power and high in coloring efficiency, because each molecule is adsorbed to an object. 
     Containing the (D2) dye allows coloring in a color which is excellent in coloring power, and then allows the colorability and toning property of the resin composition film to be improved. Examples of the (D2) dye include direct dyes, reactive dyes, sulfur dyes, vat dyes, acid dyes, metal-containing dyes, metal-containing acid dyes, basic dyes, mordant dyes, acid mordant dyes, dispersive dyes, and cationic dyes, and fluorescent whitening dyes. In this regard, the dispersive dye refers to a dye that is insoluble or poorly soluble in water, without having an anionic ionization group such as a sulfonic acid group or a carboxy group. 
     Examples of the (D2) dye include anthraquinone-based dyes, azo-based dyes, azine-based dyes, phthalocyanine-based dyes, methine-based dyes, oxazine-based dyes, quinoline-based dyes, indigo-based dyes, indigoid-based dyes, carbonium-based dyes, selenium-based dyes, perinone-based dyes, perylene-based dyes, triarylmethane-based dyes, and xanthene-based dyes. Anthraquinone-based dyes, azo-based dyes, azine-based dyes, methine-based dyes, triarylmethane-based dyes, and xanthene-based dyes are preferred from the viewpoints of solubility in solvents to be described later and heat resistance. 
     As the negative photosensitive resin composition according to the present invention, the above-described (D2) dye preferably contains one or more selected from the (D2a-1) black dye, the (D2a-2) dye mixture of two or more colors, and the (D2b) non-black dye, which will be described later. 
     The content ratio of the (D2) dye to the total solid content of the negative photosensitive resin composition according to the present invention, excluding the solvent, is preferably 0.01% by mass or higher, more preferably 0.05% by mass or higher, still more preferably 0.1% by mass or higher. When the content ratio is 0.01% by mass or higher, the colorability or the toning property can be improved. On the other hand, the content ratio of the (D2) dye is preferably 50% by mass or lower, more preferably 45% by mass or lower, still more preferably 40% by mass or lower. When the content ratio is 50% by mass or lower, the heat resistance of the cured film can be improved. 
     &lt;(D2a-1) Black Dye, (D2a-2) Dye Mixture of Two or More Colors, and (D2b) Non-Black Dye&gt; 
     As the negative photosensitive resin composition according to the present invention, the (D2) dye described above preferably contains one or more selected from the (D2a-1) black dye, the (D2a-2) dye mixture of two or more colors, and the (D2b) non-black dye. 
     The (D2a-1) black dye refers to a dye which is colored in black by absorbing light with a wavelength of visible light. Containing the (D2a-1) black dye makes the resin composition film blackened, and provides excellent colorability, thus allowing the light-blocking property of the resin composition film to be improved. 
     The (D2a-2) dye mixture of two or more colors refers to a dye mixture which is colored in pseudo black by combining two or more dyes selected from white, red, orange, yellow, green, blue, or purple dyes. Containing the (D2a-2) dye mixture of two or more colors makes the resin composition film blackened, and provides excellent colorability, thus allowing the light-blocking property of the resin composition film to be improved. Furthermore, since the two o more dyes are mixed, the adjustment of the transmission spectrum or absorption spectrum of the resin composition film, such as transmitting or blocking light with a desired specific wavelength, makes it possible to improve the toning property. As the black dye, the red dye, the orange dye, the yellow dye, the green dye, the blue dye, and the purple dye, known dyes can be used. 
     The (D2b) non-black dye refers to a dye that is colored in white, red, orange, yellow, green, blue, or purple, excluding black, by absorbing light with a wavelength of visible light. Containing the (D2b) non-black dye allows the resin composition film to be colored, and thereby allowing colorability or a toning property to be imparted. Two or more (D2b) non-black dyes are combined, thereby allowing the resin composition film to be toned to desired color coordinates, and then allows the toning property to be improved. Examples of the (D2b) non-black dye include dyes that are colored in white, red, orange, yellow, green, blue, or purple, excluding black, which are described above. 
     The cured film obtained by curing the negative photosensitive resin composition according to the present invention preferably has an optical density of 0.3 or more, more preferably 0.5 or more, even more preferably 0.7 or more, particularly preferably 1.0 or more, per film thickness of 1 μm in the visible wavelength region. The visible wavelength region is approximately 400 to 700 nm in wavelength. When the optical density per film thickness of 1 μm is 0.3 or more, the cured film allows the light-blocking property to be improved, thus making it possible to prevent electrode wirings form being made visible or reduce external light reflection, and then allowing the contrast in image display to be improved, in display devices such as an organic EL display or a liquid crystal display. For this reason, the composition is suitable for applications such as a pixel defining layer, an electrode insulation layer, a wiring insulation layer, an interlayer insulation layer, a TFT planarization layer, an electrode planarization layer, a wiring planarization layer, a TFT protective layer, an electrode protective layer, a wiring protective layer, a gate insulation layer, a color filter, a black matrix, or a black column spacer. The composition is preferred as in particular, a light-blocking pixel defining layer, electrode insulation layer, wiring insulation layer, interlayer insulation layer, TFT planarization layer, electrode planarization layer, wiring planarization layer, TFT protective layer, electrode protective layer, wiring protective layer, or gate insulating layer of an organic EL display protective layer, and suitable for applications which require contrast increased by suppression of external light reflection, such as a light-blocking pixel defining layer, interlayer insulation layer, TFT planarization layer, or TFT protective layer. On the other hand, the optical density per film thickness of 1 μm is preferably 5.0 or less, more preferably 4.0 or less, still more preferably 3.0 or less. When the optical density per film thickness of 1 μm is 5.0 or less, the sensitivity for exposure can be improved, and a cured film in a pattern in a low-taper shape can be obtained. The optical density of the cured film per film thickness of 1 μm can be adjusted depending on the composition and content ratio of the colorant (D) described above. 
     &lt;(E) Dispersant&gt; 
     The negative photosensitive resin composition according to the present invention preferably further contains the (E) dispersant. The (E) dispersant refers to a compound having a surface affinity group that interacts with the surface of a dispersive dye or the like as the (D1) pigment and/or the (D2) dye described above, and a dispersion-stabilization structure that improves the dispersion stability of a dispersive dye as the (D1) pigment and/or the (D2) dye. Examples of the dispersion stabilization structure of the (E) dispersant include a polymer chain and/or a substituent with an electrostatic charge. 
     Containing the (E) dispersant allows, in a case where the negative photosensitive resin composition contains a dispersive dye as the (D1) pigment and/or the (D2) dye, the dispersion stability to be improved, and then allows the resolution after development to be improved. In particular, for example, in a case where the (D1) pigment has particles crushed to a number average particle size of 1 μm or less, the particle surface area of the (D1) pigment is increased, thus making particle aggregation of the (D1) pigment more likely to be caused. On the other hand, in the case of containing the (E) dispersant, the interaction between the surface of the crushed (D1) pigment and the surface affinity group of the (E) dispersant, and the steric hindrance and/or electrostatic repulsion due to the dispersion-stabilization structure of the (E) dispersant make it possible to inhibit the particle aggregation of the (D1) pigment, thereby improving the dispersion stability. 
     Examples of the (E) dispersant having a surface affinity group include a (E) dispersant having only a basic group, a (E) dispersant having a basic group and an acidic group, and a (E) dispersant having only an acidic group, and a (E) dispersant having neither a basic group nor an acidic group. From the viewpoint of improving the dispersion stability of the particles of the (D1) pigment, the (E) dispersant having only a basic group and the (E) dispersant having a basic group and an acidic group are preferred. In addition, the basic group and/or the acidic group which serve as surface affinity group(s) also preferably have a structure that forms a salt with an acid and/or base.

     The amine value of the (E) dispersant is preferably 5 mgKOH/g or more, more preferably 8 mgKOH/g or more, and still more preferably 10 mgKOH/g or more. When the amine value is 5 mgKOH/g or more, the dispersion stability of the (D1) pigment can be improved. On the other hand, the amine value is preferably 150 mgKOH/g or less, more preferably 120 mgKOH/g or less, still more preferably 100 mgKOH/g or less. When the amine value is 150 mgKOH/g or less, the storage stability of the resin composition can be improved. 
     The amine value herein refers to the weight of potassium hydroxide that is equivalent to an acid that reacts with per 1 g of the (E) dispersant, and the unit is mgKOH/g. The amine value can be determined by neutralization of 1 g of the (E) dispersant with an acid, and then titration with an aqueous potassium hydroxide solution. From the amine value, the amine equivalent (unit: g/mol), which refers to the resin weight per 1 mol of basic groups such as amino groups, can be calculated, and the number of basic groups such as amino groups in the (E) dispersant can be determined. 
     The acid value of the (E) dispersant is preferably 5 mgKOH/g or more, more preferably 8 mgKOH/g or more, and still more preferably 10 mgKOH/g or more. When the acid value is 5 mgKOH/g or more, the dispersion stability of the (D1) pigment can be improved. On the other hand, the acid value is preferably 200 mgKOH/g or less, more preferably 170 mgKOH/g or less, still more preferably 150 mgKOH/g or less. When the acid value is 200 mgKOH/g or less, the storage stability of the resin composition can be improved. 
     The acid value herein refers to the weight of potassium hydroxide that reacts with 1 g of the (E) dispersant, and the unit is mgKOH/g. The acid value can be determined by titrating 1 g of the (E) dispersant with an aqueous potassium hydroxide solution. From the acid value, the acid equivalent (unit: g/mol), which refers to the resin weight per 1 mol of acidic groups, can be calculated, and the number of acidic groups in the (E) dispersant can be determined. 
     Examples of the (E) dispersant having a polymer chain, acrylic resin-based dispersants, polyoxyalkylene ether-based dispersants, polyester-based dispersants, polyurethane-based dispersants, polyol-based dispersants, polyethyleneimine-based dispersants, and polyallylamine-based dispersants. From the viewpoint of patternability with an alkaline developer, acrylic resin-based dispersants, polyoxyalkylene ether-based dispersants, polyester-based dispersants, polyurethane-based dispersants, and polyol-based dispersants are preferred. 
     In a case where the negative photosensitive resin composition according to the present invention contains a dispersive dye as the (D1) pigment and/or the (D2) dye, the content ratio of the (E) dispersant in the negative photosensitive resin composition according to the present invention is, in a case where the total of the (D1) pigment and/or dispersive dye and the (E) dispersant is regarded as 100% by mass, preferably 1% by mass or higher, more preferably 5% by mass or higher, still more preferably 10% by mass or higher. When the content ratio is 1% by mass or higher, the dispersion stability of the (D1) pigment and/or dispersive dye can be improved, and the resolution after development can be improved. On the other hand, the content ratio of the (E) dispersant is preferably 60% by mass or lower, more preferably 55% by mass or lower, still more preferably 50% by mass or lower. When the content ratio is 60% by mass or lower, the heat resistance of the cured film can be improved. 
     &lt;(F) Polyfunctional Thiol Compound&gt; 
     The negative photosensitive resin composition according to the present invention preferably further contains a chain transfer agent. The chain transfer agent refers to a compound capable of receiving a radical from a polymer growth terminal of the polymer chain obtained by radical polymerization during exposure and mediating radical transfer to another polymer chain. 
     It is preferable to contain the (F) polyfunctional thiol compound as a chain transfer agent. Containing the (F) polyfunctional thiol compound allows the sensitivity for exposure to be improved. This is presumed to be because the radicals generated by exposure are transferred to other polymer chains, thereby causing radical crosslinking even to the deep part of the film. In particular, for example, in a case where the resin composition contains the (Da) black colorant as the (D) colorant described above, the light from exposure is absorbed by the (Da) black colorant, and thus, no light may reach the deep part of the film. On the other hand, in the case of containing the (F) polyfunctional thiol compound, the radical transfer causes radical crosslinking even to the deep part of the film, thus allowing the sensitivity for exposure to be improved. 
     In addition, containing the (F) polyfunctional thiol compound allows a cured film in a low-taper pattern shape to be obtained. This is presumed to be because the radical transfer is capable of controlling the molecular weight of the polymer chain obtained by radical polymerization during exposure. More specifically, containing the (F) polyfunctional thiol compound inhibits the production of a remarkably high-molecular-weight polymer chain due to excessive radical polymerization during exposure, thereby keeping the softening point of the obtained film from being increased. Thus, it is believed that the reflow property of the pattern during the thermal curing is improved, thereby providing a low-taper pattern shape. 
     Moreover, the negative photosensitive resin composition according to the present invention contains the above-mentioned (C1-1) specific oxime ester-based photo initiator and (F) polyfunctional thiol compound, thereby allowing the residue generation during development to be inhibited, and allowing the change in pattern opening width between before and after thermal curing to be suppressed. This is presumed to be because the (G) polyfunctional thiol compound suppresses oxygen inhibition at the film surface, thereby promoting UV curing during exposure. More specifically, it is believed to be because the UV curing by the (C1-1) specific oxime ester-based photo initiator is remarkably promoted. In the case of containing, in particular, the (D1) pigment as the (D) colorant, through the suppression of oxygen inhibition at the film surface, the (D1) pigment is immobilized to the cured part by crosslinking during UV curing, thus making it possible to inhibit the residue generation after development, which is derived from the (D1) pigment. In particular, in the case of containing, in particular, a (D1a-1a) benzofuranone-based black pigment as the (Da) black colorant, a development residue derived from the pigment described above may be generated due to the insufficient alkali resistance of the above-described pigment. Even in such a case, containing the (G) polyfunctional thiol compound promotes UV curing through the suppression of oxygen inhibition at the film surface, thereby allowing the development residue generation derived from the pigment to be suppressed. 
     Furthermore, as described above, the negative photosensitive resin composition according to the present invention preferably contains the above-described (B4) alicyclic group-containing radical polymerizable compound and (F) polyfunctional thiol compound, from the viewpoints of suppressing the change in pattern opening width between before and after thermal curing and forming a pattern in a low-taper shape after development.

     The content of the (F) polyfunctional thiol compound in the negative photosensitive resin composition according to the present invention is, in a case where the total of the (A) alkali-soluble resin and (B) radical polymerizable compound is regarded as 100 parts by mass, preferably 0.01 parts by mass or more, more preferably 0.1 parts by mass or more, still more preferably 0.3 parts by mass or more, even more preferably 0.5 parts by mass or more, particularly preferably 1 part by mass or more. When the content is 0.01 parts by mass or more, the sensitivity for exposure can be improved, and a cured film in a low-taper pattern shape can be obtained. In addition, the residue generation during development can be inhibited. On the other hand, the content of the (F) polyfunctional thiol compound is preferably 15 parts by mass or less, more preferably 13 parts by mass or less, still more preferably 10 parts by mass or less, even more preferably 8 parts by mass or less, particularly preferably 5 parts by mass or less.

     &lt;Sensitizer&gt; 
     The negative photosensitive resin composition according to the present invention preferably further contains a sensitizer. The sensitizer refers to a compound capable of absorbing exposure energy, generating excited triplet electrons by internal conversion and intersystem crossing, and mediating energy transfer to the above-described (C1) photo initiator or the like. 
     Containing the sensitizer allows the sensitivity for exposure to be improved. This is presumed to be because the sensitizer absorbs long-wavelength light which is not absorbed by the (C1) photo initiator or the like, then allowing the photoreaction efficiency to be improved by energy transfer of the light from the sensitizer to the (C1) photo initiator or the like. 
     As the sensitizer, a thioxanthone-based sensitizer is preferred. Examples of the thioxanthone-based sensitizer include thioxanthone, 2-methylthioxanthone, 2-chlorothioxanthone, 2-isopropylthioxanthone, 2,4-dimethylthioxanthone, 2,4-diethylthioxanthone, and 2,4-dichlorothioxanthone. 
     The content of the sensitizer in the negative photosensitive resin composition according to the present invention is, in a case where the (A) alkali-soluble resin and the (B) radical polymerizable compound are regarded as 100 parts by mass in total, preferably 0.01 parts by mass or more, more preferably 0.1 parts by mass or more, still more preferably 0.5 parts by mass or more, particularly preferably 1 part by mass or more. When the content is 0.01 parts by mass or more, the sensitivity for exposure can be improved. On the other hand, the content of the sensitizer is preferably 15 parts by mass or less, more preferably 13 parts by mass or less, still more preferably 10 parts by mass or less, particularly preferably 8 parts by mass or less. When the content is 15 parts by mass or less, the resolution after development can be improved, and a cured film in a low-taper pattern shape can be obtained. 
     &lt;Polymerization Terminator&gt; 
     The negative photosensitive resin composition according to the present invention preferably further contains a polymerization terminator. The polymerization terminator refers to a compound capable of terminating radical polymerization by capturing a radical generated at the time of exposure, or a radical at the polymer growth terminal of the polymer chain obtained by radical polymerization at the time of exposure, and holding the radical as a stable radical. 
     Containing the polymerization terminator in an appropriate amount makes it possible to inhibit the generation of residues after development and improve the resolution after the development. This is presumed to be because the polymerization terminator captures an excessive amount of radical generated at the time of exposure or a radical at the growth terminal of the high-molecular-weight polymer chain, thereby keeping the radical polymerization from proceeding excessively. 
     As the polymerization terminator, a phenolic polymerization terminator is preferred. Examples of the phenolic polymerization terminator include 4-methoxyphenol, 1,4-hydroquinone, 1,4-benzoquinone, 2-t-butyl-4-methoxyphenol, 3-t-butyl-4-methoxyphenol, 4-t-butylcatechol, 2,6-di-t-butyl-4-methylphenol, 2,5-di-t-butyl-1,4-hydroquinone, or 2,5-di-t-amyl-1,4-hydroquinone, or IRGANOX (registered trademark) 245, 259, 565, 1010, 1035, 1076, 1098, 1135, 1330, 1425, 1520, 1726, 3114 (all manufactured by BASF). 
     The content of the polymerization terminator in the negative photosensitive resin composition according to the present invention is, in a case where the (A) alkali-soluble resin and the (B) radical polymerizable compound are regarded as 100 parts by mass in total, preferably 0.01 parts by mass or more, more preferably 0.03 parts by mass or more, still more preferably 0.05 parts by mass or more, particularly preferably 0.1 parts by mass or more. When the content is 0.01 parts by mass or more, the resolution after development and the heat resistance of the cured film can be improved. On the other hand, the content of the polymerization terminator is preferably 10 parts by mass or less, more preferably 8 parts by mass or less, still more preferably 5 parts by mass or less, particularly preferably 3 parts by mass or less. When the content is 10 parts by mass or less, the sensitivity for exposure can be improved. 
     &lt;Cross-Linking Agent&gt; 
     The negative photosensitive resin composition according to the present invention preferably further contains a cross-linking agent. The cross-linking agent refers to a compound having a cross-linkable group capable of binding to the resin. Containing the cross-linking agent allows the hardness and chemical resistance of the cured film to be improved. This is presumed to be because the cross-linking agent is capable of introducing a new cross-linked structure into the cured film of the resin composition, thus improving the crosslink density. 
     In addition, containing the cross-linking agent makes it possible to form a pattern in a low-taper shape after thermal curing. This is believed to be because the (F) cross-linking agent forms a cross-linked structure between the polymers, thereby inhibiting the tight orientation of the polymer chains, and then making it possible to maintain the reflow property of the pattern during thermal curing, and thus allowing a pattern in a low-taper shape to be formed. As the cross-linking agent, a compound having two or more thermal crosslinkable properties in the molecule, is preferred, such as an alkoxymethyl group, a methylol group, an epoxy group, or an oxetanyl group.

On the other hand, the content of the cross-linking agent is preferably 50 parts by mass or less, more preferably 40 parts by mass or less, still more preferably 30 parts by mass or less, even more preferably 25 parts by mass or less, particularly preferably 20 parts by mass or less. When the content is 50 parts by mass or less, the hardness and chemical resistance of the cured film can be improved, and a pattern in a low-taper shape can be formed after thermal curing.

     The negative photosensitive resin composition according to the present invention preferably further contains a silane coupling agent. The silane coupling agent refers to a compound having a hydrolyzable silyl group or silanol group. Containing the silane coupling agent makes it possible to increase the interaction between the cured film of the resin composition and the underlying substrate interface, thereby allowing the adhesion property to the underlying substrate and the chemical resistance of the cured film to be improved. As the silane coupling agent, a trifunctional organosilane, a tetrafunctional organosilane, or a silicate compound is preferred.

The above-described alkyl group, acyl group, and aryl group may be either unsubstituted or substituted. 
     Examples of the organosilane represented by general formula (73) include a tetrafunctional organosilane such as tetramethoxysilane, tetraethoxysilane, tetra-n-propoxysilane, tetraisopropoxysilane, tetra-n-butoxysilane, or tetraacetoxysilane, or a silicate compound such as methyl silicate 51 (manufactured by FUSO CHEMICAL CO., LTD.), M silicate 51, silicate 40, or silicate 45 (all manufactured by TAMA CHEMICALS CO., LTD.), or methyl silicate 51, methyl silicate 53A, ethyl silicate 40, or ethyl silicate 48 (all manufactured by COLCOAT CO., LTD.). 
     The content of the silane coupling agent in the negative photosensitive resin composition according to the present invention is, in a case where the (A) alkali-soluble resin and the (B) radical polymerizable compound are regarded as 100 parts by mass in total, preferably 0.01 parts by mass or more, more preferably 0.1 parts by mass or more, still more preferably 0.5 parts by mass or more, particularly preferably 1 part by mass or more.

When the content is 15 parts by mass or less, the resolution after development can be improved. 
     &lt;Surfactant&gt; 
     The negative photosensitive resin composition according to the present invention may further contain a surfactant. The surfactant refers to a compound that has a hydrophilic structure and a hydrophobic structure. Containing the surfactant in an appropriate amount allows the surface tension of the resin composition to be adjusted arbitrarily, thereby improving the leveling property for coating, and then allowing the film thickness uniformity of the coating film to be improved. As the surfactant, a fluororesin-based surfactant, a silicone-based surfactant, a polyoxyalkylene ether-based surfactant, or an acrylic resin-based surfactant is preferable.

     The negative photosensitive resin composition according to the present invention preferably further contains a solvent. The solvent refers to a compound capable of dissolving various resins and various additives to be contained in the resin composition. Containing the solvent makes it possible to uniformly dissolve various resins and various additives to be contained in the resin composition, thereby improving the transmittance of the cured film. Furthermore, the viscosity of the resin composition can be adjusted arbitrarily, and a film with a desired film thickness can be formed on the substrate. In addition, the surface tension of the resin composition or the drying speed thereof for coating can be adjusted arbitrarily, and the leveling property for coating and the film thickness uniformity of the coating film can be improved. 
     As the solvent, a compound having an alcoholic hydroxyl group, a compound having a carbonyl group, or a compound having three or more ether bonds is preferred from the viewpoint of the solubility of various resins and various additives. In addition, a compound having a boiling point of 110 to 250° C. under atmospheric pressure is more preferred. The boiling point is adjusted to 110° C. or higher, thereby causing the solvent to evaporate appropriately for coating, and then causing drying of the coating film to proceed, and thus, coating unevenness can be suppressed, and the film thickness uniformity can be improved. On the other hand, the boiling point is adjusted to 250° C. or lower, thereby allowing the amount of the solvent remaining in the coating film to be reduced. Accordingly, the amount of film shrinkage during thermal curing can be reduced, the flatness of the cured film can be improved, and the film thickness uniformity can be improved. 
     Examples of the compound having an alcoholic hydroxyl group and a boiling point of 110 to 250° C. under atmospheric pressure include diacetone alcohol, ethyl lactate, ethylene glycol monomethyl ether, propylene glycol monomethyl ether, diethylene glycol monomethyl ether, dipropylene glycol monomethyl ether, 3-methoxy-1-butanol, 3-methoxy-3-methyl-1-butanol, and tetrahydrofurfuryl alcohol.

     The content ratio of the solvent in the negative photosensitive resin composition according to the present invention can be adjusted appropriately depending on the coating method and the like. For example, in the case of forming a coating film by spin coating, it is common to adjust the ratio to 50 to 95% by mass of the whole negative photosensitive resin composition. 
     In the case of containing, as the (D) colorant, a dispersive dye as the (D1) pigment and/or (D2) dye, the solvent is preferably a solvent having a carbonyl group or an ester bond. Containing the solvent having a carbonyl group or an ester bond allows the dispersion stability of the dispersive dye to be improved as the (D1) pigment and/or (D2) dye. Furthermore, from the viewpoint of dispersion stability, the solvent is more preferably a solvent having an acetate bond. Containing the solvent having an acetate bond allows the dispersion stability of the dispersive dye to be improved as the (D1) pigment and/or (D2) dye. 
     Examples of the solvent having an acetate bond include 3-methoxy-n-butyl acetate, 3-methyl-3-methoxy-n-butyl acetate, ethylene glycol monomethyl ether acetate, propylene glycol monomethyl ether acetate, diethylene glycol monomethyl ether acetate, diethylene glycol monoethyl ether acetate, diethylene glycol mono-n-butyl ether acetate, dipropylene glycol monomethyl ether acetate, cyclohexanol acetate, propylene glycol diacetate, and 1,4-butanediol diacetate.

Examples of the other resins or precursors thereof include polyamide, polyamideimide, epoxy resins, novolac resins, urea resins, and polyurethane, and precursors thereof. 
     &lt;Method for Manufacturing Negative Photosensitive Resin Composition According to the Present Invention&gt; 
     A typical method for manufacturing the negative photosensitive resin composition according to the present invention will be described. In the case of containing the (D1) pigment including the (Da) black colorant as the (D) colorant, the (E) dispersant is added to a solution of the (A1) first resin and (A2) second resin, and with the use of a disperser, the pigment (D1) is dispersed in this mixed solution to prepare a pigment dispersion. Next, this pigment dispersion with the (B) radical polymerizable compound, the (C1) photo initiator, the other additives, and an optional solvent added thereto, is stirred for 20 minutes to 3 hours to provide a uniform solution. After the stirring, the obtained solution is filtered, thereby providing the negative photosensitive resin composition according to the present invention. 
     Examples of the disperser include a ball mill, a bead mill, a sand grinder, a triple roll mill, and a high-speed impact mill.

The bead diameter of the bead mill is preferably 0.01 to 6 mm, more preferably 0.015 to 5 mm, still more preferably 0.03 to 3 mm. In a case where the primary particle size of the (D1) pigment and the particle size of the secondary particle formed by aggregation of the primary particles are equal to or smaller than several hundred nanometers (nm), fine beads of 0.015 to 0.1 mm are preferred. In this case, a bead mill is preferred which is provided with a separator capable of separating minute beads and a pigment dispersion by a centrifugal separation method. On the other hand, in a case where the (D1) pigment contains coarse particles equal to or larger than several hundred nanometers (nm), beads of 0.1 to 6 mm are preferred from the viewpoint of more efficient dispersion. 
     &lt;Cured Pattern in Low Taper Pattern Shape&gt; 
     The negative photosensitive resin composition according to the present invention is capable of providing a cured film including a cured pattern in a low-taper pattern shape. The taper angle of the inclined side in a cross section of the cured pattern included in the cured film, obtained from the negative photosensitive resin composition according to the present invention is preferably 1° or more, more preferably 5° or more, still more preferably 10° or more, even more preferably 12° or more, particularly preferably 15° or more. When the taper angle is 1° or more, light-emitting elements can be integrated and arranged at high density, and the resolution of the display device can be thus improved. On the other hand, the taper angle of the inclined side in the cross section of the cured pattern included in the cured film is preferably 60° or less, more preferably 55° or less, still more preferably 50° or less, even more preferably 45° or less, particularly preferably 40° or less. When the taper angle is 60° or less, disconnection can be prevented in forming an electrode such as a transparent electrode or a reflective electrode. Furthermore, the electric field concentration at the edge of the electrode can be suppressed, and degradation of the light emitting elements can be thus suppressed. 
     &lt;Curing Pattern with Step Shape&gt; 
     The negative photosensitive resin composition according to the present invention is capable of forming a cured pattern that has a step shape with a sufficient difference in film thickness between a thick film part and a thin film part, and has a low-taper pattern shape, while maintaining a high sensitivity. In addition, it is possible to reduce the taper by pattern shape control after development, and it is possible to suppress the change in pattern opening width between before and after thermal curing. Thus, the step shape formed after development and the pattern opening width can be maintained after thermal curing. Accordingly, the negative photosensitive resin composition according to the present invention is particularly suitable in applications for collectively forming a step shape for a pixel defining layer in an organic EL display. Similarly, the composition is suitable in applications for collectively forming step shapes for an electrode insulation layer, a wiring insulation layer, an interlayer insulation layer, a TFT planarization layer, an electrode planarization layer, a wiring planarization layer, a TFT protective layer, an electrode protective layer, a wiring protective layer, a gate insulation layer, a color filter, a black matrix, or a black column spacer. 
       FIG. 3  shows therein a cross section example of a cured pattern which has a step shape, obtained from the negative photosensitive resin composition according to the present invention. A thick film part  34  in the step shape corresponds to a cured part during exposure, and has the maximum film thickness of the cured pattern. Thin film parts  35   a ,  35   b , and  35   c  in the step shape correspond to halftone exposed parts during exposure, and have film thicknesses smaller than the thickness of the thick film part  34 . The respective taper angles θ a , θ b , θ c , θ d , and θ e  of inclined sides  36   a ,  36   b ,  36   c ,  36   d , and  36   e  in the cross section of the cured pattern with the step shape preferably all have low tapers. 
     The taper angles θ a , θ b , θ c , θ d , and θ e  herein refer to, as shown in  FIG. 3 , angles inside the cross section of the cured pattern with the step shape, which are made by a horizontal side  37  of the underlying substrate with the cured pattern formed, or the horizontal sides of the thin film parts  35   a ,  35   b , and  35   c , and the inclined sides  36   a ,  36   b ,  36   c ,  36   d , and  36   e  in the cross section of the cured pattern with the step shape, which intersect the horizontal sides of the thin film parts  35   a ,  35   b , and  35   c . In this regard, the forward tapered shape means that the taper angle falls within the range of more than 0° and less than 90°, and the inverse tapered shape means that the taper angle falls within the range of more than 90° and less than 180°. Furthermore, the rectangular shape means that the taper angle is 90°, and the low-taper shape means that the taper angle falls within the range of more than 0° to 60°. 
     As for the thickness between the planes of the lower surface and upper surface of the cured pattern with a step shape, obtained from the negative photosensitive resin composition according to the present invention, the region with the largest thickness is regarded as a thick film part  34 , whereas the region with a thickness smaller than the thickness of the thick film part  34  is regarded as a thin film part  35 . In a case where the film thickness of the thick film part  34  is denoted by (T FT ) μm, whereas the film thicknesses of the thin film parts  35   a ,  35   b , and  35   c  disposed on the thick film part  34  with at least one step shape interposed therebetween are denoted by (T HT ) μm, the film thickness difference (ΔT FT-HT ) μm between (T FT ) and (T HT ) is preferably 0.5 μm or more, more preferably 1.0 μm or more, still more preferably 1.5 μm or more, even more preferably 2.0 μm or more, particularly preferably 2.5 μm or more, most preferably 3.0 μm or more. When the film thickness difference falls within the range described above, the area of contact with an evaporation mask in the formation of a light-emitting layer can be reduced, thereby allowing the decrease in panel yield due to particle generation to be suppressed, and allowing degradation of the light-emitting element to be suppressed. In addition, the cured pattern with a step shape has a sufficient film thickness difference by itself, thus making it possible to shorten the process time. On the other hand, the film thickness difference (ΔT FT-HT ) μm is preferably 10.0 μm or less, more preferably 9.5 μm or less, still more preferably 9.0 μm or less, even more preferably 8.5 μm or less, particularly preferably 8.0 μm or less. When the fil thickness difference falls within the range mentioned above, the exposure energy for the formation of the cured pattern with the step shape can be reduced, thereby allowing the takt time to be shortened. 
     The film thickness (T FT ) μm of the thick film part  34  and the film thicknesses (T HT ) μm of the thin film parts  35   a ,  35   b , and  35   c  preferably satisfy the relations represented by the general formulas (α) to (γ).

       2.0≤( T   FT )≤10.0  (δ)
 
       0.30≤( T   HT )≤7.0  (ε)
 
       0.15×( T   FT )≤( T   HT )≤0.70×( T   FT )  (ζ)
 
     When the film thickness (T FT ) μm of the thick film part  34  and the film thicknesses (T HT ) μm of the thin film pars  35   a ,  35   b , and  35   c  fall within the above-described ranges, degradation of the light-emitting element can be suppressed, and the process time can be shortened. 
     In the organic EL display according to the present invention, the taper angle of the inclined side in a cross section of the cured pattern with the step shape, obtained from the negative photosensitive resin composition, is preferably 1° or more, more preferably 5° or more, still more preferably 10° or more, even more preferably 12° or more, particularly preferably 15° or more. When the taper angle falls within the range described above, light-emitting elements can be integrated and arranged at high density, and the resolution of the organic EL display can be thus improved.

Furthermore, the electric field concentration at the edge of the electrode can be suppressed, and degradation of the light emitting elements can be thus suppressed.

Thereafter, (Step  3 ) the negative photosensitive resin composition according to the present invention is applied and prebaked to form a prebaked film  5   a . Then, (Step  4 ) irradiation with active actinic rays  7  is performed through a mask  6  that has a desired pattern. Next, (step  5 ) after development and pattern processing, bleaching exposure and middle baking are performed, if necessary, and thermal curing is performed, thereby forming, as a light-blocking pixel defining layer, a cured pattern  5   b  that has a desired pattern.

     &lt;Manufacturing Process for Liquid Crystal Display&gt; 
     As another process with the negative photosensitive resin composition according to the present invention, a process with the cured film of the composition as a black column spacer (hereinafter, a “BCS”) for a liquid crystal display and a black matrix (hereinafter, a “BM”) for a color filter will be described as an example with the schematic cross-sectional view shown in  FIG. 2 . 
     As shown in  FIG. 2 , first, (Step  1 ) a backlight unit (hereinafter, referred to as a “BLU”)  13  is formed on a glass substrate  12  to obtain a glass substrate  14  with the BLU. 
     Furthermore, (Step  2 ) a TFT  16  is formed on another glass substrate  15 , and a photosensitive material for a TFT planarization film is formed, subjected to pattern processing by photolithography, and then thermally cured to form a cured film  17  for TFT planarization. Next, (Step  3 ) an ITO is deposited by sputtering, and subjected to pattern processing by etching with the use of a photoresist to form a transparent electrode  18 , and a planarization film  19  and an alignment layer  20  are formed thereon. Thereafter, (Step  4 ) the negative photosensitive resin composition according to the present invention is applied and prebaked to form a prebaked film  21   a . Then, (step  5 ) irradiation with active actinic rays  23  is performed through a mask  22  that has a desired pattern. Next, (step  6 ) after development and pattern processing, bleaching exposure and middle baking are performed, if necessary, and thermal curing is performed, thereby forming, as a light-blocking BCS, a cured pattern  21   b  that has a desired pattern, and then providing a glass substrate  24  with the BCS. Then, (Step  7 ) the above-described glass substrate  14  and the glass substrate  24  are joined, thereby providing the glass substrate  25  with the BLU and the BCS. 
     Furthermore, (Step  8 ) on another glass substrate  26 , color filters  27  of three colors of red, green and blue are formed. Next, (Step  9 ) a cured pattern  28  that has a desired pattern is formed as a light-blocking BM by the same method as described above from the negative photosensitive resin composition according to the present invention. Thereafter, (Step  10 ) a photosensitive material for planarization is deposited, subjected to pattern processing by photolithography, and then thermally cured to form a cured film  29  for planarization, and an alignment layer  30  is formed thereon, thereby providing a color filter substrate  31 . Next, (Step  11 ) the above-described glass substrate  25  with the BLU and the BCS and the color filter substrate  31  are joined (Step  12 ) to obtain a glass substrate  32  with the BLU, the BCS, and the BM. Next, (Step  13 ) a liquid crystal is injected to form a liquid crystal layer  33 , thereby providing a liquid crystal display including the negative photosensitive resin composition according to the present invention as the BCS and the BM. 
     As described above, the methods for manufacturing an organic EL display and a liquid crystal display with the use of the negative photosensitive resin composition according to the present invention are capable of achieving high heat-resistance and light-blocking cured films containing polyimide and/or polybenzoxazole, subjected to pattern processing, thus leading to improvements in yield, performance, and reliability in the manufacture of organic EL displays and liquid crystal displays. 
     According to the process with the negative photosensitive resin composition according to the present invention, it is possible for the resin composition to be directly subjected to pattern processing by photolithography, because the composition is photosensitive. Accordingly, the number of steps can be reduced as compared with processes with photoresists, thus making it possible to improv the productivity of organic EL displays and liquid crystal displays, and reduce the process time and the takt time. 
     &lt;Display Device Including Cured Film Obtained from Negative Photosensitive Resin Composition According to Present Invention&gt; 
     The cured film obtained from the negative photosensitive resin composition according to the present invention can suitably constitute an organic EL display or a liquid crystal display. 
     Moreover, the negative photosensitive resin composition according to the present invention is capable of achieving a low-taper pattern shape, thereby making it possible to obtain a cured film which is excellent in high heat resistance. Thus, the composition is suitable for applications which require high heat resistance and low-taper pattern shapes, such as an insulation layer such as a pixel defining layer of an organic EL display, a TFT planarization layer, or a TFT protective layer. In particular, in applications in which problems due to heat resistance and pattern shapes are expected, such as element failures or characteristic degradation due to degassing by thermal decomposition, or electrode wiring disconnection due to high-taper pattern shapes, the use of a cured film of the negative photosensitive resin composition according to the present invention makes it possible to manufacture a highly reliable element where the above-described problems are not caused. Furthermore, the cured film is excellent in light-blocking property, thus allowing electrode wiring to be prevented from becoming visible or allowing external light reflection to be reduced, and the contrast in image display can be thus improved. Accordingly, the use of the cured film obtained from the negative photosensitive resin composition according to the present invention as a pixel defining layer of an organic EL display device, a TFT planarization layer, or a TFT protective layer can improve the contrast, without forming any polarizing plate and a quarter wavelength plate on the light extraction side of the light-emitting element.

     &lt;Method for Pattern Processing of Coating Film Formed on Substrate&gt; 
     Examples of the method for pattern processing of the coating film of the negative photosensitive resin composition according to the present invention formed on the substrate include a method of direct pattern processing by photolithography and a method of pattern processing by etching. From the viewpoint of improving productivity by reducing the number of steps and reducing the process time, a method of direct pattern processing by photolithography is preferred. 
     &lt;Step of Irradiation with Active Actinic Ray Through Photomask&gt; 
     The method for manufacturing a display device with the use of the negative photosensitive resin composition according to the present invention includes the (2) step of irradiating the above-described coating film of the negative photosensitive resin composition with active actinic rays through a photomask. Onto the substrate, the negative photosensitive resin composition according to the present invention is applied and prebaked to form a film, and then exposed with the use of an exposure machine such as a stepper, a mirror projection mask aligner (MPA), or a parallel light mask aligner (PLA). Examples of the active actinic rays in irradiation for the exposure include ultraviolet light, visible light, electron beams, X-rays, KrF (wavelength: 248 nm) lasers, and ArF (wavelength: 193 nm) lasers. It is preferable to use j-lines (wavelength: 313 nm), i-lines (wavelength: 365 nm), h-lines (wavelength: 405 nm), or g-lines (wavelength: 436 nm) from a mercury lamp. In addition, the exposure energy is typically approximately 100 to 40,000 J/m 2  (10 to 4,000 mJ/cm 2 ) (i-line illuminance meter value), and exposure can be performed through a photomask that has a desired pattern, if necessary. 
     After the exposure, post-exposure baking may be performed. By performing the post-exposure baking, effects can be expected, such as an improved resolution after development or increased tolerance for development conditions. The post-exposure baking can use an oven, a hot plate, infrared rays, a flash annealing device, a laser annealing device, or the like. The post-exposure baking temperature is preferably 50 to 180° C., more preferably 60 to 150° C. The post-exposure baking time is preferably 10 seconds to several hours. When the post-exposure baking time is 10 seconds to several hours, the reaction may proceed favorably, thereby shortening the development time. 
     In the method for producing a display device with the use of the negative photosensitive resin composition according to the present invention, it is preferable to use a half-tone photomask as the photomask. The half-tone photomask refers to a photomask that has a pattern including a light-transmitting portion and a light-blocking portion, the photomask having, between the light-transmitting portion and the light-blocking portion, a partial light-transmitting portion that is lower in transmittance than the value of the light-transmitting portion and higher in transmittance than the value of the light-blocking portion. The exposure with the use of the half-tone photomask makes it possible to form a pattern which has a step shape after development and after thermal curing. It is to be noted that the cured part irradiated with active actinic rays through the light-transmitting portion corresponds to the thick film part, whereas the half-tone exposed part irradiated with active actinic rays through the partial light-transmitting portion corresponds to the thin film part. 
     In the method for manufacturing a display device with the use of the negative photosensitive resin composition according to the present invention, the halftone photomask has a site where the light-transmitting portion and the partial light-transmitting portion are adjacent to each other. Having the site where the light-transmitting portion and the partial light-transmitting portion are adjacent to each other makes it possible to form a pattern including the thick film part corresponding to the light-transmitting portion on the photomask after development and the thin film part corresponding to the partial light-transmitting portion on the photomask. Moreover, the halftone photomask has a site where the light-blocking portion and the partial light-transmitting portion are adjacent to each other. After development, a pattern including an opening corresponding to the light-blocking portion on the photomask and the thin film part corresponding to the partial light-transmitting portion on the photomask can be formed. The halftone photomask has the site mentioned above, thereby making it possible to form a pattern with a step shape, including the thick film part, the thin film part, and the opening, after development. 
     As the half-tone photomask, in a case where the transmittance of the light-transmitting portion is denoted by (% T FT ) %, the transmittance (% T HT )% of the partial light-transmitting portion is preferably 10% or more of (% T FT ), more preferably 15% or more thereof, further preferably 20% or more thereof, particularly preferably 25% or more thereof. When the transmittance (% T HT )% of the partial light-transmitting portion falls within the range mentioned above, the exposure energy at the time of the formation of the cured pattern which has the step shape can be reduced, thus allowing the cycle time to be shortened. On the other hand, the transmittance (% T HT )% of the partial light-transmitting portion is preferably 60% or less of (% T FT ), more preferably 55% or less thereof, further preferably 50% or less thereof, particularly preferably 45% or less thereof. When the transmittance (% T HT )% of the partial light-transmitting portion falls within the range mentioned above, the film thickness difference between the thick film part and the thin film part and the film thickness difference between adjacent thin film parts on both sides of any step can be made sufficiently large, thus allowing degradation of the light-emitting element to be suppressed. In addition, the cured pattern with a step shape has a sufficient film thickness difference by itself, thus making it possible to shorten the process time. 
     In the cured pattern with a step shape, obtained by irradiation with active actinic rays through the halftone photomask, the film thickness difference (ΔT HT30-HT20 ) μm between (T HT30 ) and (T HT20 ) is preferably 0.3 μm or more, more preferably 0.5 μm or more, still more preferably 0.7 μm or more, particularly preferably 0.8 μm or more, in a case where the film thickness of the thin film part with which the transmittance (% T HT )% of the partial light-transmitting portion is 30% of (% T FT ) is denoted by (T HT30 ) μm, whereas the film thickness of the thin film part with which the transmittance (% T HT )% of the partial light-transmitting portion is 20% of (% T FT ) is denoted by (T HT20 ) μm. When the film thickness difference falls within the range mentioned above, the film thickness difference between the thick film part and the thin film part and the film thickness difference between adjacent thin film parts on both sides of any step can be made sufficiently large, thus allowing degradation of the light-emitting element to be suppressed. In addition, the cured pattern with a step shape has a sufficient film thickness difference by itself, thus making it possible to shorten the process time. On the other hand, the film thickness difference (ΔT HT30-HT20 ) μm is preferably 1.5 μm or less, more preferably 1.4 μm or less, still more preferably 1.3 μm or less, particularly preferably 1.2 μm or less. When the film thickness difference falls within the range mentioned above, the variation in film thickness due to a slight fluctuation in exposure energy, caused by the apparatus or the like, can be reduced, thereby improving the film thickness uniformity and the yield in organic EL display manufacture. 
     &lt;Step of Performing Development with Alkaline Solution to Form Pattern&gt; 
     The method for manufacturing a display device with the use of the negative photosensitive resin composition according to the present invention includes the (3) step of performing development with the use of an alkaline solution to form a pattern of the negative photosensitive resin composition described above. After the exposure, development is performed with the use of an automatic development device or the like. The negative photosensitive resin composition according to the present invention has negative photosensitivity, and thus, after the development, the unexposed part is removed with a developer, thereby allowing a relief pattern to be obtained. 
     As the developer, an alkaline developer is typically used. As the alkaline developer, for example, an organic alkaline solution or an aqueous solution of an alkaline compound is preferred, and an aqueous solution of an alkaline compound, that is, an alkaline aqueous solution is more preferred from the viewpoint of the environment aspect. 
     Examples of the organic alkaline solution or alkaline compound include 2-aminoethanol, 2-(dimethylamino)ethanol, 2-(diethylamino)ethanol, diethanolamine, methylamine, ethylamine, dimethylamine, diethylamine, triethylamine, acetic acid (2-dimethylamino)ethyl, (meth)acrylic acid (2-dimethylamino)ethyl, cyclohexylamine, ethylenediamine, hexamethylenediamine, ammonia, tetramethylammonium hydroxide, tetraethylammonium hydroxide, sodium hydroxide, potassium hydroxide, magnesium hydroxide, calcium hydroxide, barium hydroxide, sodium carbonate, and potassium carbonate, and from the viewpoint of reducing metal impurities in the cured film and suppressing defective display in the display device, tetramethylammonium hydroxide or tetraethylammonium hydroxide is preferred. As the developer, an organic solvent may be used. As the developer, a mixed solution may be used which contains both the organic solvent and a poor solvent with respect to the negative photosensitive resin composition according to the present invention. 
     Examples of the development method include paddle development, spray development, and dip development. Examples of the paddle development include a method of applying the above-described developer directly to the exposed film, and then leaving the film for an arbitrary period of time, and a method of applying the above-described developer by spraying in the form of a mist to the exposed film for an arbitrary period of time, and then leaving the film for an arbitrary period of time. Examples of the spray development include a method of keeping on spraying the above-described developer in the form of a mist to the exposed film for an arbitrary period of time. Examples of the dip development include a method of immersing the exposed film in the developer described above for an arbitrary period of time, and a method of immersing the exposed film in the developer described above, and then keeping on irradiation with ultrasonic waves for an arbitrary period of time. From the viewpoint of suppressing device contamination during the development and reducing the process cost by reducing the usage of the developer, the paddle development is preferred as the development method. Device contamination during the development is suppressed, thereby allowing substrate contamination during the development to be suppressed, and then allowing defective display in the display device to be suppressed. On the other hand, from the viewpoint of inhibiting the residue generation after development, the spray development is preferred as the development method. In addition, from the viewpoint of reducing the usage of the developer by reuse of the developer and reducing the process cost, the dip development is preferred as the development method. 
     The development time is preferably 5 seconds or longer, more preferably 10 seconds or longer, still more preferably 30 seconds or longer, particularly preferably 1 minute or longer. When the development time falls within the range described above, the residue generation during the alkali development can be inhibited. On the other hand, from the viewpoint of reducing the takt time, the development time is preferably 30 minutes or shorter, more preferably 15 minutes or shorter, still more preferably 10 minutes or shorter, particularly preferably 5 minutes or shorter. 
     After the development, the obtained relief pattern is preferably washed with a rinse solution. As the rinse solution, water is preferred in a case where an alkaline aqueous solution is used as the developer. As the rinsing solution, for example, an aqueous solution of an alcohol such as ethanol or isopropyl alcohol, an aqueous solution of an ester such as propylene glycol monomethyl ether acetate, or an aqueous solution of an acidic compound such as carbon dioxide, hydrochloric acid, or acetic acid may be used. As the rinse solution, an organic solvent may be used. 
     &lt;Step of Photo-Curing Pattern&gt; 
     The method for manufacturing a display device with the use of the negative photosensitive resin composition according to the present invention preferably includes the (3) step of performing development with the use of an alkaline solution to form a pattern of the negative photosensitive resin composition, and then further, a step of photo-curing the pattern of the negative photosensitive resin composition. 
     The step of photo-curing the pattern improves the crosslink density of the pattern, and then reduces the quantity of low-molecular components which cause degassing, thus improving the reliability of the light-emitting element including the pattern of the negative photosensitive resin composition. Furthermore, in a case where the pattern of the negative photosensitive resin composition is a pattern with a step shape, pattern reflow during thermal curing of the pattern can be suppressed, and a pattern that has a step shape with a sufficient film thickness difference between the thick film part and the thin film part can be formed even after thermal curing. In addition, maintaining the reflow property of the film surface during thermal curing improves the flatness, thereby making it possible to suppress the decrease in panel yield. Moreover, in the manufacture of the organic EL display including the pattern of the negative photosensitive resin composition, the area of contact with an evaporation mask in the formation of an organic EL layer can be reduced, thereby allowing the decrease in panel yield due to particle generation to be suppressed, and allowing degradation of the light-emitting element to be suppressed. 
     As the step of photo-curing the pattern, it is preferable to irradiate the pattern of the negative photosensitive resin composition with active actinic rays. Examples of the method of irradiation with active actinic rays include a method of bleaching exposure with the use of an exposure machine such as a stepper, a scanner, a mirror projection mask aligner (MPA), or a parallel light mask aligner (PLA). Examples of the lamp for use in irradiation with active actinic rays in the step of photo-curing the pattern include an ultra-high pressure mercury lamp, a high-pressure mercury lamp, a low-pressure mercury lamp, a metal halide lamp, a Xe excimer lamp, a KrF excimer lamp, or an ArF excimer lamp. 
     Examples of the active actinic rays in the step of photo-curing the pattern include ultraviolet light, visible light, electron beams, X-rays, XeF (wavelength: 351 nm) lasers, XeCl (wavelength: 308 nm) lasers, KrF (wavelength: 248 nm) lasers, or ArF (Wavelength: 193 nm) lasers. From the viewpoints of suppressing pattern reflow during thermal curing of the pattern, improving the step film thickness, and suppressing the decrease in panel yield, the j-lines (wavelength: 313 nm), i-lines (wavelength: 365 nm), h-lines (wavelength: 405 nm), or g-lines (wavelength: 436 nm) of a mercury lamp, or a mixed ray of i-line, h-line and g-line is preferred. 
     The exposure energy of the active actinic rays in the step of photo-curing the pattern is preferably 100 J/m 2  (10 mJ/cm 2 ) or more in terms of i-line illuminance value. On the other hand, the exposure energy of the active actinic rays is preferably 50,000 J/m 2  (5,000 mJ/cm) or less in terms of i-line illuminance value. When the exposure energy falls within the range mentioned above, pattern reflow during thermal curing of the pattern of the negative photosensitive resin composition can be suppressed. In addition, the decrease in panel yield can be suppressed.

When the exposure energy ratio falls within the range mentioned above, pattern reflow during thermal curing of the pattern of the negative photosensitive resin composition can be suppressed.

The middle baking can use an oven, a hot plate, infrared rays, a flash annealing device, a laser annealing device, or the like. The middle baking temperature is preferably 50 to 250° C., more preferably 70 to 220° C. The middle baking time is preferably 10 seconds to several hours.

     &lt;Step of Heating Pattern to Obtain Cured Pattern&gt; 
     The method for manufacturing a display device with the use of the negative photosensitive resin composition according to the present invention includes the (4) step of heating the pattern of the negative photosensitive resin composition described above to obtain a cured pattern of the negative photosensitive resin composition described above. For heating the pattern of the negative photosensitive resin composition according to the present invention, formed on the substrate, an oven, a hot plate, infrared rays, a flash annealing device, a laser annealing device, or the like can be used. The pattern of the negative photosensitive resin composition according to the present invention is cured and then thermally cured, thereby allowing the heat resistance of the cured film to be improved, and allowing a low-taper pattern shape to be obtained. 
     The temperature for thermosetting is preferably 150° C. or higher, more preferably 200° C. or higher, and further preferably 250° C. or higher. When the thermal curing temperature is 150° C. or higher, the heat resistance of the cured film can be improved, and the pattern shape after the thermal curing can be further reduced in taper. On the other hand, from the viewpoint of shortening the tact time, the thermosetting temperature is preferably 500° C. or lower, more preferably 450° C. or lower, and further preferably 400° C. or lower. 
     The time for the thermal curing is preferably 1 minute or longer, more preferably 5 minutes or longer, still more preferably 10 minutes or longer, particularly preferably 30 minutes or longer. When the thermal curing time is 1 minute or longer, the pattern shape after the thermal curing can be further reduced in taper. On the other hand, from the viewpoint of reducing the takt time, the time for the thermal curing is preferably 300 minutes or shorter, more preferably 250 minutes or shorter, still more preferably 200 minutes or shorter, particularly preferably 150 minutes or shorter. Thermal curing in two or more stages may be performed, such as thermal curing at 150° C. for 30 minutes, and then thermal curing at 250° C. for 30 minutes. 
     Further, the negative photosensitive resin composition a to the present invention makes it possible to obtain cured films which are suitably used for applications such as a pixel defining layer, an electrode insulation layer, a wiring insulation layer, an interlayer insulation layer, a TFT planarization layer, an electrode planarization layer, a wiring planarization layer, a TFT protective layer, an electrode protective layer, a wiring protective layer, a gate insulation layer, a color filter, a black matrix, or a black column spacer. Moreover, it becomes possible to obtain an elements and display devices including the cured films. The organic EL display according to the present invention includes the above-mentioned cured film as one or more selected from the group consisting of a pixel defining layer, an electrode insulation layer, a wiring insulation layer, an interlayer insulation layer, a TFT planarization layer, an electrode planarization layer, a wiring planarization layer, a TFT protective layer, an electrode protective layer, a wiring protective layer, a gate insulation layer, a color filter, a black matrix, and a black column spacer. In particular, the negative photosensitive resin composition according to the present invention is excellent in light-blocking property, and thus more preferred as a light-blocking pixel defining layer, electrode insulation layer, wiring insulation layer, interlayer insulation layer, TFT planarization layer, electrode planarization layer, wiring planarization layer, TFT protective layer, electrode protective layer, wiring protective layer, or gate insulating layer of an organic EL display protective layer, and suitable for applications which require contrast increased by suppression of external light reflection, such as a light-blocking pixel defining layer, interlayer insulation layer, TFT planarization layer, or TFT protective layer. 
     Furthermore, the methods for manufacturing a display device with the use of the negative photosensitive resin composition according to the present invention are capable of achieving high heat-resistance and light-blocking cured films containing polyimide and/or polybenzoxazole, subjected to pattern processing, thus leading to improvements in yield, performance, and reliability in the manufacture of organic EL displays and liquid crystal displays. In addition, since the negative photosensitive resin composition according to the present invention is capable of being directly subjected to pattern processing by photolithography, the number of steps can be reduced as compared with processes with photoresists, thus making it possible to improv the productivity, and reduce the process time and the takt time.

     Covering Example 1—Synthesis of Surface-Covered Benzofuranone-Based Black Pigment (Bk-CBF1) 
     As a black pigment, 150 g of benzofuranone-based black pigment Bk-S0100CF (surface-untreated product; pH 4.5 at the pigment surface) was put into a glass container containing 2,850 g of deionized water, and stirred with a dissolver, thereby providing an aqueous pigment suspension. This suspension was sacked up with a tube pump, fed into a horizontal bead mill filled with 0.4 mmφ zirconia beads (“TORAYCERAM” (registered trademark); manufactured by Toray Industries, Inc.) and subjected to a 2-pass dispersion treatment therein, then entirely discharged into the original glass container, and stirred again with a dissolver. With a pH meter such that the electrode tip was immersed at a depth of 3 to 5 cm from the liquid surface of the aqueous pigment suspension being stirred in the glass container, the pH of the obtained aqueous pigment suspension was measured, and then, the pH meter read pH 4.5 (liquid temperature: 25° C.). Thereafter, the temperature of the aqueous pigment suspension was raised to 60° C. while stirring, and the stirring was temporarily stopped after 30 minutes, then after 2 minutes, it was confirmed that there was no sediment deposited on the bottom of the glass container, and stirring was restarted. 
     To the aqueous pigment suspension, a sodium silicate aqueous solution (Na 2 O-nSiO 2 -mH 2 O; 30% by mass as sodium oxide, 10% by mass as silicon dioxide) diluted 1/100 with deionized water and a 0.001 mol/L sulfuric acid were added in parallel while adjusting the respective addition rates so as to maintain the pH in the range of 2 or more and less than 7, such that the covering amount of silica was 10.0 parts by mass in terms of SiO 2  with respect to 100 parts by mass of the black pigment, thereby depositing silica on the particle surface of the black pigment to cover the surface. Then, to the aqueous pigment suspension, a sodium aluminate aqueous solution (Na 2 O-nAl 2 O 3 -mH 2 O; 40% by mass as sodium oxide, 50% by mass as alumina) diluted 1/100 with deionized water and a 0.001 mol/L sulfuric acid were added in parallel while adjusting the respective addition rates so as to maintain the pH in the range of 2 or more and less than 7, such that the covering amount of alumina was 2.0 parts by mass in terms of Al 2 O 3  with respect to 100 parts by mass of the black pigment, thereby depositing alumina on the surface of the silica covering layer to cover the surface. Subsequently, filtration and water washing operations were repeated three times to remove some of water-soluble impurities in the aqueous pigment suspension, and the suspension was fed into a horizontal bead mill filled with 0.4 mmφ zirconia beads, and subjected to a 1-pass dispersion treatment therein. Furthermore, in order to remove ionic impurities, 10 g of a cation exchange resin and 10 g of an anion exchange resin (Amberlite; manufactured by ORGANO CORPORATION) were put in the aqueous pigment suspension, then stirred for 12 hours, and filtered to obtain a black filter cake. This filter cake was dried in a drying oven at 90° C. for 6 hours and in a drying oven at 200° C. for 30 minutes, and then subjected to granulation by dry grinding with the use of a jet mill, thereby providing a surface-covered benzofuranone-based black pigment (Bk-CBF1). 
     As a result of time-of-flight secondary ion mass spectrometry and X-ray diffraction analysis, the silica and alumina covering amounts of the surface-covered benzofuranone-based black pigment (Bk-CBF1) obtained were respectively 10.0 parts by mass in terms of SiO 2  and 2.0 parts by mass in terms of Al 2 θ 3  with respect to 100 parts by mass of the black pigment, and the average coverage of the covering layer with respect to the pigment was 97.5%. 
     Preparation Example 1—Preparation of Pigment Dispersion (Bk-1) 
     After 34.5 g of S-20000 as a dispersant, 782.0 g of MBA as a solvent were weighed, and mixed, and diffused by stirring for 10 minutes, 103.5 g of Bk-S0100CF as a colorant was weighed, and then mixed with the dispersant and the solvent, and stirred for 30 minutes, and subjected to a wet media dispersion treatment with the use of a horizontal bead mill filled with 0.40 mmφ zirconia beads such that the number average particle size was 100 nm, thereby providing a pigment dispersion (Bk-1) with a solid content concentration 15% by mass, and colorant/dispersant=75/25 (mass ratio). The number average particle size of the pigment in the obtained pigment dispersion was 100 nm. 
     Preparation Example 2—Preparation of Pigment Dispersion (Bk-2) 
     After 92.0 g of a 30% by mass MBA solution of the polyimide (PI-1) obtained in accordance with Synthesis Example 1 as a resin, 27.6 g of S-20000 as a dispersant, 717.6 g of MBA as a solvent were weighed, and mixed, and diffused by stirring for 10 minutes, 82.8 g of Bk-S0100CF as a colorant was weighed, and then mixed with the dispersant and the solvent, and stirred for 30 minutes, and subjected to a wet media dispersion treatment with the use of a horizontal bead mill filled with 0.40 mmφ zirconia beads such that the number average particle size was 100 nm, thereby providing a pigment dispersion (Bk-2) with a solid content concentration 15% by mass, and colorant/resin/dispersant=60/20/20 (mass ratio). The number average particle size of the pigment in the obtained pigment dispersion was 100 run.

     With the types and ratios of the colorant, (A1) first resin, and (E) dispersant, listed in Table 2-1, pigments were dispersed in the same manner as in Preparation Example 2, thereby providing a pigment dispersion (Bk-3) to a pigment dispersion (Bk-18). 
     The compositions according to Preparation Examples 1 to 18 are collectively shown in Table 2-1.

The Si wafer (manufactured by ELECTRONICS AND MATERIALS CORPORATION LIMITED) was dehydrated and baked by heating at 130° C. for 2 minutes with the use of a hot plate (HP-1SA; manufactured by AS ONE Corporation), and used. 
     (7) Film Thickness Measurement 
     With the use of a surface texture and contour measuring instrument (SURFCOM 1400D; manufactured by TOKYO SEIMITSU CO., LTD.), at the measurement magnification of 10,000 times, the measurement length of 1.0 mm, the measurement speed of 0.30 mm/s, the film thickness was measured after prebaking, after development, and after curing. 
     (8) Sensitivity 
     In accordance with the method described in Example 1 below, after exposure for patterning with the i-line (wavelength: 365 nm), h-line (wavelength: 405 nm), and g-line (wavelength 436 nm) of an ultra-high pressure mercury lamp through a gray scale mask (MDRM MODEL 4000-5-FS; Opto-Line International, Inc.) for sensitivity measurement with the use of a double-sided alignment single-sided exposure apparatus (Mask Aligner PEM-6M; manufactured by Union Optical Co., Ltd.), development was performed with the use of a small-size development device (AD-2000; TAKIZAWA SANGYO K.K.) for photolithography, thereby preparing a developed film of the negative photosensitive resin composition. 
     With the use of a FPD/LSI inspection microscope (OPTIPHOT-300; manufactured by NIKON CORPORATION), the resolution pattern of the developed film prepared was observed, and the exposure energy (i-line illuminance meter value) for the formation of the 20 μm line-and-space pattern with a one-to-one width was regarded as the sensitivity. It has been determined as follows that the A+, A, B, and C with the sensitivity of 90 mJ/cm 2  or less are regarded as pass, the A+, A, and B with the sensitivity of 60 mJ/cm 2  or less are regarded as favorable sensitivities, and the A+ and A with the sensitivity of 45 mJ/cm 2  or less are regarded as excellent sensitivities. 
     A+: The sensitivity is 1 to 30 mJ/cm 2    
     A: The sensitivity is 31 to 45 mJ/cm 2    
     B: The sensitivity is 46 to 60 mJ/cm 2

     In accordance with the method described in Example 1 below, after exposure for patterning with the i-line (wavelength: 365 nm), h-line (wavelength: 405 nm), and g-line (wavelength 436 nm) of an ultra-high pressure mercury lamp through a gray scale mask (MDRM MODEL 4000-5-FS; Opto-Line International, Inc.) for sensitivity measurement with the use of a double-sided alignment single-sided exposure apparatus (Mask Aligner PEM-6M; manufactured by Union Optical Co., Ltd.), development was performed with the use of a small-size development device (AD-2000; TAKIZAWA SANGYO K.K.) for photolithography, and a cured film of the negative photosensitive resin composition was then prepared with the use of a high-temperature inert gas oven (INH-9CD-S; manufactured by Koyo Thermo Systems Co., Ltd.). 
     After the thermal curing, the cured film prepared was scraped from the substrate, and about 10 mg of the film was put in an aluminum cell. This aluminum cell was, with the use of a thermogravimetric measurement device (TGA-50; manufactured by Shimadzu Corporation), held at 30° C. for 10 minutes in a nitrogen atmosphere, then heated to 150° C. at a temperature increase rate of 10° C./min, and thereafter, held at 150° C. for 30 minutes, and furthermore, a thermogravimetric analysis was carried out while increasing the temperature up to 500° C. at a temperature increase rate of 10° C./min.

     (16) Light-Emitting Characteristics of Organic EL Display (Method for Manufacturing Organic EL Display) 
       FIG. 4  shows a schematic diagram of the substrate used. First, ITO transparent conductive coatings of 10 nm were formed on the entire surface of a 38×46 mm non-alkali glass substrate  47  by sputtering, and etched as a first electrode  48  to form a transparent electrode. In addition, an auxiliary electrode  49  was formed at the same time to take out a second electrode ( FIG. 4  (Step  1 )). The obtained substrate was subjected to ultrasonic cleaning for 10 minutes with “Semico Clean” (registered trademark) 56 (manufactured by Furuuchi Chemical Corporation), and washed with ultrapure water. Next, the negative photosensitive resin composition was applied and prebaked on the substrate by the method described in Example 1, subjected to patterning exposure through a photomask with a predetermined pattern, and development and rinsing, and then thermally cured by heating. In accordance with the method mentioned above, openings of 70 μm in width and 260 μm in length were arranged at a pitch of 155 μm in the width direction and a pitch of 465 μm in the length direction, and an insulation layer  50  in a shape for exposing the first electrode through the respective openings was formed only on a substrate effective area in a limited fashion ( FIG. 4  (Step  2 )). It is to be noted that the openings will finally serve for light-emitting pixels of an organic EL display. Further, the substrate effective area was a square of 16 mm on a side, and the insulation layer  50  was formed to have a thickness of about 1.0 μm. 
     Next, an organic EL display was manufactured with the use of the substrate with the first electrode  48 , auxiliary electrode  49 , and insulation layer  50  formed. After the substrate was subjected to a nitrogen plasma treatment as a pretreatment, an organic EL layer  51  including a light-emitting layer was formed by vacuum deposition ( FIG. 4  (Step  3 )). It is to be noted that the degree of vacuum for the deposition was 1×10 −3  Pa or less, and during the deposition, the substrate was rotated with respect to a deposition source. First, a compound (HT-1) of 10 nm and a compound (HT-2) of 50 nm were deposited respectively as a hole injection layer and a hole transport layer. Next, for the light-emitting layer, a compound (GH-1) as a host material and a compound (GD-1) as a dopant material were deposited to have a thickness of 40 nm, in such a way that the dope concentration reached 10%. Thereafter, as an electron transport material, a compound (ET-1) and a compound (LiQ) were laminated at a volume ratio of 1:1 to have a thickness of 40 nm. Here are the structures of the compounds used for the organic EL layer. 
     
       
         
         
             
             
         
       
       
         
         
             
             
         
       
     
     Next, after the vapor deposition of the compound (LiQ) of 2 nm, 100 nm MgAg (magnesium/silver=10/1 (volume ratio)) was deposited as a second electrode  52  to form a reflective electrode ( FIG. 4  (Step  4 )). Thereafter, under a low-humidity nitrogen atmosphere, sealing was performed by bonding a cap-shaped glass plate with the use of an epoxy resin-based adhesive, and four bottom-emission organic EL displays each in a square shape of 5 mm on a side were prepared on one substrate. It is to be noted that the film thickness herein refers to a value displayed on a crystal oscillation-type film thickness monitor. 
     (Light-Emitting Characteristic Evaluation) 
     The organic EL displays prepared by the method described above was driven with a direct current at 10 mA/cm 2  to emit light, and it was confirmed whether there were defective light emissions such as non-light-emitting areas and uneven luminance. The prepared organic EL displays were held at 80° C. for 500 hours as a durability test. After the durability test, the organic EL displays prepared by the method described above was driven with a direct current at 10 mA/cm 2  to emit light, and it was confirmed whether there was any change in light-emitting characteristics such as light-emitting areas and uneven luminance. It has been determined as follows that, in a case where the light-emitting area before the durability test is regarded as 100%, the A+, A, and B where the light-emitting area after the durability test is 80% or higher are regarded as pass, A+ and A where the light-emitting area is 90% or higher are regarded as favorable light-emitting characteristics, and A+ where the light-emitting area is 95% or higher is regarded as an excellent light-emitting characteristic. 
     A+: The light-emitting area after the durability test is 95 to 100%. 
     A: The light-emitting area after the durability test is 90 to 94%. 
     B: The light-emitting area after the durability test is 80 to 89-. 
     C: The light-emitting area after the durability test is 70 to 79%. 
     D: The light-emitting area after the durability test is 50 to 69% 
     E: The light emitting area after the durability test is 0 to 49%.

     The prepared composition 1 was applied onto an ITO substrate by spin coating at an arbitrary rotation speed with the use of a spin coater (MS-A100; manufactured by Mikasa Co., Ltd.), and then prebaked at 110° C. for 120 seconds with the use of a buzzer hot plate (HPD-3000BZN; manufactured by AS ONE Corporation) to prepare a prebaked film of about 1.8 μm in film thickness. 
     The prebaked film prepared was subjected to spray development with a 2.38% by mass TMAH aqueous solution with the use of a small-size development device (AD-2000; manufactured by TAKIZAWA SANGYO K.K.) for photolithography, and the time at which the prebaked film (unexposed part) was completely dissolved (Breaking Point; hereinafter, a “B.P.”) was measured. 
     in the same manner as described above, a prebaked film was prepared, and the prepared prebaked film was subjected to exposure for patterning with the i-line (wavelength: 365 nm), h-line (wavelength: 405 nm), and g-line (wavelength 436 nm) of an ultra-high pressure mercury lamp through a gray scale mask (MDRM MODEL 4000-5-FS; Opto-Line International, Inc.) for sensitivity measurement with the use of a double-sided alignment single-sided exposure apparatus (Mask Aligner PEM-6M; manufactured by Union Optical Co., Ltd.), development was performed with the use of a small-size development device (AD-2000; TAKIZAWA SANGYO K.K.) for photolithography, thereby preparing a developed film of the photosensitive resin composition. After the exposure, the film was subjected to development with a 2.38% by mass TMAH aqueous solution with the use of a small-size development device (AD-2000; manufactured by TAKIZAWA SANGYO K.K.) for photolithography, and rinsed with water for 30 seconds. The development time was 1.5 times as long as B.P. 
     After the development, with the use of a high-temperature inert gas oven (INH-9CD-S; manufactured by Koyo Thermo Systems Co., Ltd.), thermal curing was performed at 250° C. to produce a cured film of about 1.2 μm in film thickness. The thermal curing condition was thermal curing at 250° C. for 60 minutes in a nitrogen atmosphere.

     (Method for Manufacturing Organic EL Display without Polarizing Layer) 
       FIG. 5  shows therein an outline of an organic EL display to e prepared. First, a laminated film of chromium and gold was formed by an electron beam evaporation method on 38×46 mm non-alkali glass substrate  53 , and a source electrode  54  and drain electrode  55  were formed by etching. Next, APC (silver/palladium/copper=98.07/0.87/1.06 (mass ratio)) of 100 nm was deposited by sputtering, and subjected to pattern processing by etching to form an APC layer, and an ITO of 10 nm was further deposited by sputtering for an upper layer on the APC layer, and etched to form a reflective electrode  56  as a first electrode. After cleaning the electrode surface with oxygen plasma, an amorphous IGZO was deposited by sputtering, and etched to form an oxide semiconductor layer  57  between the source and drain electrodes. Next, a positive photosensitive polysiloxane-based material (SP-P2301; manufactured by Toray Industries, Inc.) was deposited by a spin coating method, and after making a via hole  58  and a pixel region  59  as openings by photolithography, thermally cured to form a gate insulation layer  60 . Thereafter, gold was deposited by an electron beam evaporation method, and etched to form a gate electrode  61 , thereby providing an oxide TFT array. 
     In accordance with the above-described method described in Example 1, the composition 7 was applied and prebaked on the oxide TFT array to form a film, and the film was subjected to exposure for patterning through a photomask with a predetermined pattern, and development and rinsing to make a pixel region as an opening, and then thermally cured to form a TFT protective layer/pixel defining layer  62  with light-blocking property. In accordance with the method described above, openings of 70 μm in width and 260 μm in length were arranged at a pitch of 155 μm in the width direction and a pitch of 465 μm in the length direction, and the pixel defining layer in a shape for exposing the reflective electrode through the respective openings was formed only on a substrate effective area in a limited fashion. It is to be noted that the openings will finally serve for light-emitting pixels of an organic EL display. Further, the substrate effective area was a square of 16 mm on a side, and the pixel defining layer was formed to have a thickness of about 1.0 μm. 
     Next, an organic EL light-emitting layer  63  was formed by the method described in the section (16) described above, with the use of the compound (HT-1) as a hole injection layer, the compound (HT-2) as a hole transport layer, the compound (GH-1) as a host material, the compound (GD-1) as a dopant material, and the compound (ET-1) and the compound (LiQ) as electron transport materials. 
     Thereafter, MgAg (magnesium/silver=10/1 (volume ratio)) of 10 nm was deposited by a vapor deposition method, and etched to form a transparent electrode  64  as a second electrode. Then, a sealing film  65  was formed with the use of an organic EL sealing material (Structbond (registered trademark) XMF-T; manufactured by Mitsui Chemicals, Inc.) under a low-humidity nitrogen atmosphere. Furthermore, a non-alkali glass substrate  66  was bonded onto the sealing film, thereby preparing, on one substrate, four top-emission organic EL displays each of 5 mm on a side without any polarizing layer. It is to be noted that the film thickness herein refers to a value displayed on a crystal oscillation-type film thickness monitor. 
     (Light-Emitting Characteristic Evaluation) 
     The organic EL display prepared by the method described above was allowed to emit light by direct-current drive at 10 mA/cm 2 , and the luminance (Y′) in the case of irradiating the pixel defining layer part with external light, and the luminance (Y 0 ) in the case of irradiating the part with no external light were measured. As an index for reduction in external light reflection, the contrast was calculated by the following equation: 
       Contrast= Y   0   /Y′   
     It has been determined as follows that A+, A, and B where the contrast is 0.80 or more are regarded as pass, A+ and A where the contrast is 0.90 or more are regarded as favorable effects of reduction in external light reflection, and A+ where the contrast is 0.95 or more is regarded as an excellent effect of reduction in external light reflection. It has been confirmed that the organic EL display prepared by the above-described method has contrast of 0.90, and has ability to reduce external light reflection. 
     A+: The contrast is 0.95 to 1.00. 
     A: The contrast is 0.90 to 0.94. 
     B: The contrast is 0.80 to 0.89. 
     C: The contrast is 0.70 to 0.79. 
     D: The contrast is 0.50 to 0.69. 
     E: The contrast is 0.01 to 0.49. 
     Example 85 
     (Evaluation of Halftone Characteristics) 
     In accordance with the method described in Example 1 as described above, a prebaked film of the composition 7 was formed to have a film thickness of 5 μm on an ITO substrate, subjected to exposure for patterning with the i-line (wavelength: 365 nm), h-line (wavelength: 405 nm), and g-line (wavelength 436 nm) of an ultra-high pressure mercury lamp through a halftone photomask for halftone characteristic evaluation with the use of a double-sided alignment single-sided exposure apparatus (Mask Aligner PEM-6M; manufactured by Union Optical Co., Ltd.) such that the exposure energy for the light-transmitting portion reached the exposure energy for the sensitivity in the case of the film thickness of 5 μm after prebaking, and developed with the use of a small-size developing device (AD-2000; TAKIZAWA SANGYO K.K.) for photolithography, and a cured film of the composition 7 was then prepared with the use of a high-temperature inert gas oven (INH-9CD-S; manufactured by Koyo Thermo Systems Co., Ltd.). 
     Photomasks including a light-transmitting portion, a light-blocking portion, and a partial light-transmitting portion between the light-transmitting portion and the light-blocking portion were used as the halftone photomask. The photomasks have sites where the transmittances (% T HT )% of the partial light-transmitting portions are respectively 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, and 50% of the transmittance (% T FT ) of the light-transmitting portion. The light-transmitting portion is adjacent to the partial light-transmitting portion, and the partial light-transmitting portion is adjacent to the light-blocking portion. The pattern shapes of the light-transmitting portion, partial light-transmitting portion, and light-blocking portion each have a site in a line shape. The light-transmitting portion and the light-blocking portion each have a site in a quadrangular shape. The light-transmitting portions each have a site of 2 μm, 5 μm, 10 μm, 15 μm, 20 μm, 30 μm, 40 μm, 50 μm, or 100 μm in pattern width. In addition, the light-blocking portions are 10 μm in pattern width. On the other hand, the partial light-transmitting portions each have a site of 2 μm, 5 μm, 10 μm, 15 μm, 20 μm, 25 μm, 30 μm, 35 μm, 40 μm, 45 μm, 50 μm, and 100 μm in pattern width. 
       FIG. 6  shows, as an example of the halftone photomask, an example of the arrangement and dimensions of the light-transmitting portion, light-blocking portion, and partial light-transmitting portion. 
     With the use of a surface texture and contour measuring instrument (SURFCOM 1400D; TOKYO SEIMITSU CO., LTD.), at the measurement magnification of 10,000 times, the measurement length of 1.0 mm, the measurement speed of 0.30 mm/s, the film thickness of the light-transmitting portion after development and the film thickness (T FT ) μm thereof after the thermal curing were measured. For the partial light-transmitting portions, the film thicknesses of sites different in transmittance after development and the film thicknesses (T HT ) μm thereof after thermal curing were measured, thereby determining the minimum film thickness (T HT/min ) μm after thermal curing of the partial light-transmitting portion left as a residual film after development. As an index of halftone characteristics, the maximum step film thickness was calculated by the following formula: 
       Maximum Step Film Thickness=( T   FT )−( T   HT/min ).
 
     It has been determined as follows that A+, A, and B, and C where the maximum step film thickness is 1.0 μm or more are regarded as pass, A+, A, and B where the maximum step film thickness is 1.5 μm or more are regarded as favorable halftone characteristics, and A+ and A where the maximum step film thickness is 2.0 μm or more are regarded as excellent half-tone characteristics. It has been confirmed that the cured film of the composition 7 prepared by the method mentioned above has a light-transmitting portion of 4.0 μm in film thickness (T FT ) after thermal curing, and a partial light-transmitting portion of 2.3 μm in minimum film thickness (T HT/min ) after thermal curing, and thus have a maximum step film thickness of 1.7 μm, and have excellent halftone characteristics. 
     A+: The maximum step film thickness is 2.5 μm or more. 
     A: The maximum step film thickness is 2.0 μm or more and less than 2.5 μm. 
     B: The maximum step film thickness is 1.5 μm or more and less than 2.0 μm. 
     C: The maximum step film thickness is 1.0 μm or more and less than 1.5 μm. 
     D: The maximum step film thickness is 0.5 μm or more and less than 1.0 μm. 
     E: The maximum step thickness is 0.1 μm or more and less than 0.5 μm. 
     F: The maximum step film thickness is less than 0.1 μm or not measurable without any residual film after the development. 
     In accordance with similar manners, the halftone characteristics were evaluated with the use of the compositions 18 to 35, 60 to 68, 1, 5, 43, 45, 47, 48, 51, 53, 54, 56 to 59, and 78 to 81 as Examples 86 to 129, and the compositions 87, 88, 84, 90, and 89 as Comparative Examples 9 to 13. The evaluation results of Examples 85 to 129 and Comparative Examples 9 to 13 are shown in Table 15-1 and Table 15-2.
