Title: Aromatic heterocyclic derivative, and organic electroluminescent element, illumination device, and display device using aromatic heterocyclic derivative

Description:
TECHNICAL FIELD 
     The present invention relates to an aromatic heterocyclic derivative, an organic electroluminescent element using the same, a lighting device, and a display device. More specifically, the present invention relates to an aromatic heterocyclic derivative, an organic electroluminescent element which uses the same and having high emission efficiency, a long emission lifetime, and a small deterioration with time when used even under a high-temperature condition, a lighting device and a display device provided with this organic electroluminescent element. 
     BACKGROUND 
     An organic electroluminescent element (hereafter, it may be called as “an organic EL element”) is a thin-film type total solid element having a constitution of an organic film layer (a single layer or a plurality of layers) containing an organic luminescent substance interposed between an anode and a cathode. When an electric filed is applied to an organic EL element, a hole is injected from an anode and an electron is injected from a cathode into an organic film layer. The hole and the electron are recombined in a light emitting layer (a layer containing an organic luminescent substance) to produce an exciton. An organic electroluminescent element is a luminescent element which uses light emission (fluorescence or phosphorescence) from this exciton. This is a technology expected to become a flat display or a lighting device of the next generation. 
     It was reported the following from the Princeton University. In principle, an organic EL element utilizing phosphorescence emission from the excited triplet will realize an emission efficiency of 4 times larger compared with an emission efficiency of an organic EL element utilizing fluorescence emission. Since then, there have been investigated all over the world the materials exhibiting phosphorescence emission at room temperature, the layer constitution and the electrode of the luminescent element. 
     As described above, a phosphorescence emission mode has a very high potential. However, in an organic EL element utilizing phosphorescence emission, the method of controlling the position of the emission center, in particular, the method of recombination inside of the light emitting layer to stably carrying out emission is a technological problem to be solved for improving efficiency and lifetime of the element. This is a large difference from an organic EL element utilizing fluorescence emission. 
     In recent years, it has been well known a multi-laminated layer type element which is provided with a hole transport layer located in the anode side of the light emitting layer, or an electron transport layer located in the cathode side of the light emitting later. Further, as a light emitting layer, it has been often used a mixed layer containing a phosphorescence emitting compound as a light emitting dopant and a host compound. 
     On the other hand, from the viewpoint of materials, it is expected to create a novel material for achieving an improved property of the element. In particular, it was reported an organic EL element material which uses a host compound for a phosphorescence emitting compound. This host compound contains a multi-condensed ring compound bonded with a 6-membered nitrogen containing heterocyclic ring through an arylene linking group (refer to Patent documents 1 to 3, for example). 
     When the compounds described in the Patent documents 1 to 3 are used for organic EL element materials, 
     a lifetime and an emission efficiency of the element were improved to some extent. However, the improvement was not sufficient. Further improvement was required. Further, it was found that the organic EL elements using these compounds had a defect of inferior thermal stability.

     Effects of the Invention 
     By the above-described embodiments of the present invention, it is possible to provide a novel aromatic heterocyclic derivative. Further, it is possible to provide an organic electroluminescent element which uses the same and having high emission efficiency, a long emission lifetime, and a small deterioration with time when used even under a high-temperature condition. Moreover, it is possible to provide a display device and a lighting device provided with this organic electroluminescent element. 
     A formation mechanism or an action mechanism of the effects of the present invention is not clearly identified, but it is supposed as follows. 
     A driving voltage of an organic EL element is preferably small. This may be achieved by making the highest occupied molecular orbital energy level (HOMO level) of the compound used for the element to be high, and by making the lowest unoccupied molecular orbital energy level (LUMO level) to be low. By this, an injection property of the charge in to the light emitting layer will be increased and a driving voltage may be lowered. 
     However, when the HOMO level is made to be high and the LUMO level is made to be low, the excited singlet (S 1  energy) becomes small, and the excited triplet (T 1  energy) also becomes small. In particular, when a host compound is used for a phosphorescence emitting dopant, this decrease of the T 1  energy becomes a problem. 
     As a means to solve this problem, one of the ways may be to make the difference (ΔEst) between the Si energy and the T 1  energy to be small. 
     By making ΔEst to be small, the T 1  energy level can be kept high. It may be obtained the same energy as the decreased Si energy by making the HOMO level to be high and the LUMO level to be low. It can be understood by the following scheme describing the relationship of ΔEst, the Si energy, and the T 1  energy. 
     
       
      
       T 
       1 
       =S 
       1 
       −ΔEst  
      
     
     ΔEst may be made to be small by decreasing an interaction of parallel spins in the molecule. Namely, it may be achieved by making apart the center distance between the HOMO localized portion and the LUMO localized portion. In the compound of the present invention, the center of HOMO is made to be localized on the carbazole ring, and the center of LUMO is made to be localized on the 6-membered nitrogen containing heteroaromatic ring. Further, a preferably, each center portion is made to be at the terminal of the molecule. However, the 6-membered nitrogen containing heteroaromatic ring without a substituent is unstable when the ring has a large number of nitrogen atoms. Therefore, it is required to introduce a minimum number of appropriate substituents. 
     When a flexible group such as an alkylene group is introduced in a portion where the carbazole ring and the 6-membered nitrogen containing heterocyclic ring are bonded, the rigidity of the whole molecule is decreased. As a result, it will be induced a problem that the molecule tends to cause a morphological change in the film. Therefore, in the aromatic heterocyclic derivative of the present invention, it was introduced a condensed ring structure (containing X) between the carbazole ring and the 6-membered nitrogen containing heterocyclic ring. This condensed ring structure does not affect the localized portions of HOMO and LUMO, and improves the rigidity of the whole molecule. By this embodiment, the above-described problem was resolved. Further, by the introduction of the condensed ring structure (containing X), it was supposed the following: Tg (glass transition temperature) was increased, aggregation and crystallization were prevented, decrease of efficiency and lifetime was prevented, and stability under high-temperature condition was improved. 
     By the design that the localized centers of HOMO and LUMO are located at the terminal of the molecule, the hopping transfer of electrons becomes easier Consequently, the temporal change of carrier transferring efficiency was restrained and the lifetime of the element was improved. 
     In addition, when the size of the molecule is unnecessarily large, a sublimation property of the molecule will be lowered, and vapor deposition will become difficult. This will lead to decrease in productivity. Therefore, preferably, the molecule has a molecular weight suitable for vapor deposition. 
     Further, when a substituent is introduced to the condensed ring structure (containing X), it is possible to apply a synthetic method of high regioselectivity. As a result, the compound may be synthesized with high yield and high purity. It may be produced the compound with an appropriate cost. 
     Through suitable selection of the substituent on the carbazole ring, the compound of the present invention will have an improved thermal stability. It enables to achieve an element having an improved thermal stability under heating condition over a long period of time.

     Synthesis of Intermediate 1 
     33.6 mg (200 mmol) of dibenzofuran was dissolved in 700 ml of THF under a nitrogen atmosphere. To this was added 350 ml of n-butyl lithium (1.6 mol/1 hexane solution) at −70° C. or less. After completion of addition, the mixture was stirred at −70° C. or less for 1 hour. Then, the reaction mixture was heated to 0° C. and it was stirred for 1 hour. The reaction mixture was cooled again to −70° C. or less, and 45 g (300 ml) of 1,2-dibromoethane was added dropwise. After completion of drop, the reaction mixture was stirred for 12 hours. Then, water was added to the reaction mixture, and the reaction product was extracted with ethyl acetate. The organic layer was washed with water, and the solvent was removed under a reduced pressure. The produced residue was recrystallized with hexane to obtain 37.1 g of an intermediate 1. The yield was 75%. The structure of the compound was confirmed with NMR and mass spectrum. 
     Synthesis of Intermediate 2 
     24.7 g (100 mmol) of the intermediate 1 was dissolved in 200 ml of N,N-dimethyl acetamide under a nitrogen atmosphere. To this were added 17.6 g (105 mmol) of carbazole, 14.3 g (150 mmol) of copper powder, and 27.6 g (200 mmol) of potassium carbonate. Then the mixture was stirred at 170° C. for 12 hours. After cooling the reaction solution, it was poured into 500 ml of water. The precipitated solid was filtered. The filtered solid was dissolved in ethyl acetate, and an insoluble matter was removed with filtration. The solvent was removed from the filtrate under a reduced pressure. The obtained solid was recrystallized with methanol to obtain 33.3 g of an intermediate 2. The yield was 80%. The structure of the compound was confirmed with NMR and mass spectrum. 
     Synthesis of Exemplary Compound 619 
     16.7 g (50 mmol) of the intermediate 2 was dissolved in 300 ml of THF under a nitrogen atmosphere. To this was added 90 ml of n-butyl lithium (1.6 mol/l hexane solution) at −70° C. or less. After completion of addition, the mixture was stirred at −70° C. or less for 1 hour. Then, the reaction mixture was heated to 0° C. and it was stirred for 1 hour. The reaction mixture was cooled again to −70° C. or less, and to this was added a solution of 14.7 g (55 mmol) of 1-chloro-3,5-diphenyltriazine dissolved in 80 ml of THF. After completion of addition, the reaction mixture was stirred at room temperature for 6 hours. Then, water was added to the reaction mixture, and the precipitated product was filtered. The raw product was purified with silica gel chromatography then recrystallized with methanol. Further, the product was recrystallized with acetonitrile to obtain 25.4 g of an exemplary compound 619. The yield was 90%. The structure of the compound was confirmed with NMR and mass spectrum. 
     The other compounds of the present invention may be synthesized in the same method. 
     &lt;&lt;Constitution Layers of Organic EL Element&gt;&gt; 
     Representative element constitutions used for an organic EL element of the present invention are as follows, however, the present invention is not limited to these. 
     (1) Anode/light emitting layer/cathode
 
(2) Anode/light emitting layer/electron transport layer/cathode
 
(3) Anode/hole transport layer/light emitting layer/cathode
 
(4) Anode/hole transport layer/light emitting layer/electron transport layer/cathode
 
(5) Anode/hole transport layer/light emitting layer/electron transport layer/electron injection layer/cathode
 
(6) Anode/hole injection layer/hole transport layer/light emitting layer/electron transport layer/cathode
 
(7) Anode/hole injection layer/hole transport layer/(electron blocking layer/) light emitting layer/(hole blocking layer/) electron transport layer/electron injection layer/cathode Among these, the embodiment (7) is preferably used. However, the present invention is not limited to this.
 
     The light emitting layer of the present invention is composed of one or a plurality of layers. When a plurality of layers are employed, it may be placed a non-light emitting intermediate layer between the light emitting layers. 
     According to necessity, it may be provided with a hole blocking layer (it is also called as a hole barrier layer) or an electron injection layer (it is also called as a cathode buffer layer) between the light emitting layer and the cathode. Further, it may be provided with an electron blocking layer (it is also called as an electron barrier layer) or an hole injection layer (it is also called as an anode buffer layer) between the light emitting layer and the anode. 
     An electron transport layer according to the present invention is a layer having a function of transporting an electron. An electron transport layer includes an electron injection layer, and a hole blocking layer in a broad sense. Further, an electron transport layer unit may be composed of plural layers. 
     A hole transport layer according to the present invention is a layer having a function of transporting a hole. A hole transport layer includes a hole injection layer, and an electron blocking layer in a broad sense. Further, a hole transport layer unit may be composed of plural layers. 
     In the representative element constitutions as described above, the layers eliminating an anode and a cathode are also called as “organic layers”. 
     (Tandem Structure) 
     An organic EL element of the present invention may be so-called a tandem structure element in which plural light emitting units each containing at least one light emitting are laminated. 
     A representative example of an element constitution having a tandem structure is as follows. 
     Anode/first light emitting unit: second light emitting unit/third light emitting unit cathode: and Anode, first light emitting unit intermediate layer/second light emitting unit/intermediate layer/third light emitting unit/cathode. 
     Here, the above-described first light emitting unit, second light emitting unit, and third light emitting unit may be the same or different. It may be possible that two light emitting units are the same and the remaining one light emitting unit is different. 
     In addition, the third light emitting unit may not be provided. Otherwise, a further light emitting unit or a further intermediate layer may be provided between the third light emitting unit and the electrode. 
     The plural light emitting units each may be laminated directly or they may be laminated through an intermediate layer. Examples of an intermediate layer are: an intermediate electrode, an intermediate conductive layer, a charge generating layer, an electron extraction layer, a connecting layer, and an intermediate insulating layer. Known composing materials may be used as long as it can form a layer which has a function of supplying an electron to an adjacent layer to the anode, and a hole to an adjacent layer to the cathode.

The constitutions of the elements and the composing materials are described in these documents, however, the present invention is not limited to them. 
     Each layer that constitutes an organic EL element of the present invention will be described in the following. 
     &lt;&lt;Light Emitting Layer&gt;&gt; 
     A light emitting layer according to the present invention is a layer which provide a place of emitting light via an exciton produce by recombination of electrons and holes injected from an electrode or an adjacent layer. The light emitting portion may be either within the light emitting layer or at an interface between the light emitting layer and an adjacent layer thereof. The constitution of the light emitting layer according to the present invention is not particularly limited as long as it satisfies the requirements of the present invention. 
     A total thickness of the light emitting layer is not particularly limited. However, in view of layer homogeneity, required voltage during light emission, and stability of the emitted light color against a drive electric current, the total layer thickness is preferably adjusted to be in the range of 2 nm to 5 μm, more preferably, it is in the range of 2 to 500 nm, and still most preferably, it is in the range of 5 to 200 nm. 
     Each light emitting layer is preferably adjusted to be in the range of 2 nm to 1 μm, more preferably, it is in the range of 2 to 200 nm, and still most preferably, it is in the range of 3 to 150 nm. 
     It is preferable that the light emitting layer of the present invention incorporates a light emitting dopant (it may be simply called as a dopant) and a host compound (it may be called as a light emitting host, or simply called as a host). 
     (1) Light Emitting Dopant 
     A light emitting dopant according to the present invention will be described. 
     As a light emitting dopant, it is preferable to employ: a fluorescence emitting dopant (also referred to as a fluorescent dopant and a fluorescent compound) and a phosphorescence emitting dopant (also referred to as a phosphorescent dopant and a phosphorescent emitting compound). In the present invention, it is preferable that at least one light emitting layer contains a phosphorescence emitting dopant. 
     A concentration of a light emitting compound in a light emitting layer may be arbitrarily decided based on the specific compound employed and the required conditions of the device. A concentration of a light emitting compound may be uniform in a thickness direction of the light emitting layer, or it may have any concentration distribution. 
     It may be used plural light emitting compounds of the present invention. It may be used a combination of fluorescent compounds each having a different structure, or a combination of a fluorescence emitting compound and a phosphorescence emitting compound. Any required emission color will be obtained by this. 
     Color of light emitted by an organic EL element or a compound of the present invention is specified as follows. In FIG. 4.16 on page 108 of “Shinpen Shikisai Kagaku Handbook (New Edition Color Science Handbook)” (edited by The Color Science Association of Japan, Tokyo Daigaku Shuppan Kai, 1985), values determined via Spectroradiometer CS-1000 (produced by Konica Minolta, Inc.) are applied to the CIE chromaticity coordinate, whereby the color is specified. 
     In the present invention, it is preferable that the organic EL element of the present invention exhibits white emission by incorporating one or plural light emitting layers containing plural light emitting dopants having different emission colors. 
     The combination of light emitting dopants producing white is not specifically limited. It may be cited, for example, combinations of: blue and orange; and blue, green and red. 
     It is preferable that “white” in the organic EL element of the present invention exhibits chromaticity in the CIE 1931 Color Specification System at 1,000 cd/m 2  in the region of x=0.39±0.09 and y=0.38±0.08, when measurement is done to 2-degree viewing angle front luminance via the aforesaid method. 
     (1.1) Phosphorescence Emitting Dopant 
     A phosphorescence emitting dopant according to the present invention will be described. Hereafter, it may be called as “a phosphorescence dopant”. 
     The phosphorescence emitting dopant is a compound which is observed emission from an excited triplet state thereof. Specifically, it is a compound which emits phosphorescence at a room temperature (25° C.) and exhibits a phosphorescence quantum yield of at least 0.01 at 25° C. The phosphorescence quantum yield is preferably at least 0.1. 
     The phosphorescence quantum yield will be determined via a method described in page 398 of Bunko II of Dai 4 Han Jikken Kagaku Koza 7 (Spectroscopy II of 4th Edition Lecture of Experimental Chemistry 7) (1992, published by Maruzen Co. Ltd.). The phosphorescence quantum yield in a solution will be determined using appropriate solvents. However, it is only necessary for the phosphorescent dopant of the present invention to exhibit the above phosphorescence quantum yield (0.01 or more) using any of the appropriate solvents. 
     Two kinds of principles regarding emission of a phosphorescent dopant are cited. One is an energy transfer-type, wherein carriers recombine on a host compound on which the carriers are transferred to produce an excited state of the host compound, and then via transfer of this energy to a phosphorescent dopant, emission from the phosphorescence-emitting dopant is realized. The other is a carrier trap-type, wherein a phosphorescence-emitting dopant serves as a carrier trap and then carriers recombine on the phosphorescent dopant to generate emission from the phosphorescent dopant. In each case, the excited state energy level of the phosphorescent dopant is required to be lower than that of the host compound. 
     A phosphorescence dopant may be suitably selected and employed from the known materials used for a light emitting layer for an organic EL element. 
     Examples of a known phosphorescence dopant are compounds described in the following publications.

     An electron transport layer of the present invention is composed of a material having a function of transferring an electron. It is only required to have a function of transporting an injected electron from a cathode to a light emitting layer.

     In an organic EL element, it is known that there occurs interference between the light directly taken from the light emitting layer and the light reflected at the electrode located at the opposite side of the electrode from which the light is taken out at the moment of taking out the light which is produced in the light emitting layer. When the light is reflected at the cathode, it is possible to use effectively this interference effect by suitably adjusting the total thickness of the electron transport layer in the range of 5 nm to 1 μm. 
     On the other hand, the voltage will be increased when the layer thickness of the electron transport layer is made thick. Therefore, especially when the layer thickness is large, it is preferable that the electron mobility in the electron transport layer is 1×10 −5  cm 2 N/Vs or more. 
     As a material used for an electron transport layer (hereafter, it is called as an electron transport material), it is only required to have either a property of ejection or transport of electrons, or a barrier to holes. Any of the conventionally known compounds may be selected and they may be employed.

     Formation of organic layers of the present invention is preferably continuously carried out from a hole injection layer to a cathode with one time vacuuming. It may be taken out on the way, and a different layer forming method may be employed. In that case, the operation is preferably done under a dry inert gas atmosphere.

Further, a material such as IDIXO (In 2 O 3 —ZnO), which may form an amorphous and transparent electrode, may also be used. 
     As for an anode, these electrode substances may be made into a thin layer by a method such as a vapor deposition method or a sputtering method; followed by making a pattern of a desired form by a photolithography method. Otherwise, when the requirement of pattern precision is not so severe (about 100 μm or more), a pattern may be formed through a mask of a desired form at the time of layer formation with a vapor deposition method or a sputtering method using the above-described material. 
     Alternatively, when a coatable substance such as an organic conductive compound is employed, it is possible to employ a wet film forming method such as a printing method or a coating method. When emitted light is taken out from the anode, the transmittance is preferably set to be 10% or more. A sheet resistance of the anode is preferably a few hundred Ω/□ or less.

     Further, after forming a layer of the aforesaid metal having a thickness of 1 to 20 nm on the cathode, it is possible to prepare a transparent or translucent cathode by providing with a conductive transparent material described in the description for the anode thereon. By applying this process, it is possible to produce an element in which both an anode and a cathode are transparent. 
     &lt;&lt;Support Substrate&gt;&gt; 
     A support substrate which may be used for an organic EL element of the present invention is not specifically limited with respect to types such as glass and plastics. Hereafter, the support substrate may be also called as substrate body, substrate, substrate substance, or support. They may be transparent or opaque. However, a transparent support substrate is preferable when the emitting light is taken from the side of the support substrate. Support substrates preferably utilized includes such as glass, quartz and transparent resin film. A specifically preferable support substrate is a resin film capable of providing an organic EL element with a flexible property. 
     Examples of a resin film include: polyesters such as polyethylene terephthalate (PET) and polyethylene naphthalate (PEN), polyethylene, polypropylene, cellophane, cellulose esters and their derivatives such as cellulose diacetate, cellulose triacetate (TAC), cellulose acetate butyrate, cellulose acetate propionate (CAP), cellulose acetate phthalate, and cellulose nitrate, polyvinylidene chloride, polyvinyl alcohol, polyethylene vinyl alcohol, syndiotactic polystyrene, polycarbonate, norbornene resin, polymethyl pentene, polyether ketone, polyimide, polyether sulfone (PES), polyphenylene sulfide, polysulfones, polyether imide, polyether ketone imide, polyamide, fluororesin, Nylon, polymethyl methacrylate, acrylic resin, polyallylates and cycloolefin resins such as ARTON (trade name, made by JSR Co.

Barrier films are preferred with a water vapor permeability of 0.01 g/(m 2 ·24 h) or less (at 25±0.5° C. and 90±2% RH) determined based on JIS K 7129-1992.

     As materials that form a barrier film, employed may be those which retard penetration of moisture and oxygen, which deteriorate the element. For example, it is possible to employ silicon oxide, silicon dioxide, and silicon nitride. Further, in order to improve the brittleness of the aforesaid film, it is more preferable to achieve a laminated layer structure of inorganic layers and organic layers. The laminating order of the inorganic layer and the organic layer is not particularly limited, but it is preferable that both are alternatively laminated a plurality of times.

     &lt;&lt;Sealing&gt;&gt; 
     As sealing means employed in the present invention, listed may be, for example, a method in which sealing members, electrodes, and a supporting substrate are subjected to adhesion via adhesives. The sealing members may be arranged to cover the display region of an organic EL element, and may be a concave plate or a flat plate. Neither transparency nor electrical insulation is limited. 
     Specifically listed are glass plates, polymer plate-films, metal plate-films. Specifically, it is possible to list, as glass plates, soda-lime glass, barium-strontium containing glass, lead glass, aluminosilicate glass, borosilicate glass, barium borosilicate glass, and quartz. Further, listed as polymer plates may be polycarbonate, acryl, polyethylene terephthalate, polyether sulfide, and polysulfone. As a metal plate, listed are those composed of at least one metal selected from the group consisting of stainless steel, iron, copper, aluminum magnesium, nickel, zinc, chromium, titanium, molybdenum, silicon, germanium, and tantalum, or alloys thereof. 
     In the present invention, since it is possible to achieve a thin organic EL element, it is preferable to employ a polymer film or a metal film. Further, it is preferable that the polymer film has an oxygen permeability of 1×10 −3  ml/(m 2 ·24 h·atm) or less determined by the method based on JIS K 7126-1987, and a water vapor permeability of 1×10 −3  g/(m 2 ·24 h) or less (at 25±0.5° C., and 90±2% RH) determined by the method based on JIS K 7129-1992. 
     Conversion of the sealing member into concave is carried out by employing a sand blast process or a chemical etching process. 
     In practice, as adhesives, listed may be photo-curing and heat-curing types having a reactive vinyl group of acrylic acid based oligomers and methacrylic acid, as well as moisture curing types such as 2-cyanoacrylates. Further listed may be thermal and chemical curing types (mixtures of two liquids) such as epoxy based ones. Still further listed may be hot-melt type polyamides, polyesters, and polyolefins. Yet further listed may be cationically curable type UV curable epoxy resin adhesives. 
     In addition, since an organic EL element is occasionally deteriorated via a thermal process, preferred are those which enable adhesion and curing between a room temperature and 80° C. Further, desiccating agents may be dispersed into the aforesaid adhesives. Adhesives may be applied onto sealing portions via a commercial dispenser or printed on the same in the same manner as screen printing. 
     Further, it is appropriate that on the outside of the aforesaid electrode which interposes the organic layer and faces the support substrate, the aforesaid electrode and organic layer are covered, and in the form of contact with the support substrate, inorganic and organic material layers are formed as a sealing film. In this case, as materials that form the aforesaid film may be those which exhibit functions to retard penetration of moisture or oxygen which results in deterioration. For example, it is possible to employ silicon oxide, silicon dioxide, and silicon nitride. 
     Still further, in order to improve brittleness of the aforesaid film, it is preferable that a laminated layer structure is formed, which is composed of these inorganic layers and layers composed of organic materials. Methods to form these films are not particularly limited. It is possible to employ, for example, a vacuum deposition method, a sputtering method, a reactive sputtering method, a molecular beam epitaxy method, a cluster ion beam method, an ion plating method, a plasma polymerization method, an atmospheric pressure plasma polymerization method, a plasma CVD method, a thermal CVD method, and a coating method. 
     It is preferable to inject a gas phase and a liquid phase material of inert gases such as nitrogen or argon, and inactive liquids such as fluorinated hydrocarbon or silicone oil into the space between the space formed with the sealing member and the display region of the organic EL element. Further, it is possible to form vacuum in the space. Still further, it is possible to enclose hygroscopic compounds in the interior of the space. 
     Examples of a hygroscopic compound include: metal oxides (for example, sodium oxide, potassium oxide, calcium oxide, barium oxide, magnesium oxide, and aluminum oxide): sulfates (for example, sodium sulfate, calcium sulfate, magnesium sulfate, and cobalt sulfate); metal halides (for example, calcium chloride, magnesium chloride, cesium fluoride, tantalum fluoride, cerium bromide, magnesium bromide, barium iodide, and magnesium iodide): perchlorates (for example, barium perchlorate and magnesium perchlorate). In sulfates, metal halides, and perchlorates, suitably employed are anhydrides. For sulfate salts, metal halides and perchlorates, suitably used are anhydrous salts. 
     &lt;&lt;Protective Film and Protective Plate&gt;&gt; 
     On the aforesaid sealing film which interposes the organic layer and faces the support substrate or on the outside of the aforesaid sealing film, a protective or a protective plate may be arranged to enhance the mechanical strength of the element. Specifically, when sealing is achieved via the aforesaid sealing film, the resulting mechanical strength is not always high enough, therefore it is preferable to arrange the protective film or the protective plate described above. Usable materials for these include glass plates, polymer plate-films, and metal plate-films which are similar to those employed for the aforesaid sealing. However, from the viewpoint of reducing weight and thickness, it is preferable to employ a polymer film. 
     &lt;&lt;Improving Method of Light Extraction&gt;&gt; 
     It is generally known that an organic EL element emits light in the interior of the layer exhibiting the refractive index (being about 1.6 to 2.1) which is greater than that of air, whereby only about 15% to 20% of light generated in the light emitting layer is extracted. This is due to the fact that light incident to an interface (being an interlace of a transparent substrate to air) at an angle of 6 which is at least critical angle is not extracted to the exterior of the element due to the resulting total reflection, or light is totally reflected between the transparent electrode or the light emitting layer and the transparent substrate, and light is guided via the transparent electrode or the light emitting layer, whereby light escapes in the direction of the element side surface. 
     Means to enhance the efficiency of the aforesaid light extraction include, for example: a method in which roughness is formed on the surface of a transparent substrate, whereby total reflection is minimized at the interface of the transparent substrate to air (U.S. Pat. No. 4,774,435), a method in which efficiency is enhanced in such a manner that a substrate results in light collection (JP-A No. 63-314795), a method in which a reflection surface is formed on the side of the element (JP-A No. 1-220394), a method in which a flat layer of a middle refractive index is introduced between the substrate and the light emitting body and an antireflection film is formed (JP-A No. 62-172691), a method in which a flat layer of a refractive index which is equal to or less than the substrate is introduced between the substrate and the light emitting body (JP-A No. 2001-202827), and a method in which a diffraction grating is formed between the substrate and any of the layers such as the transparent electrode layer or the light emitting layer (including between the substrate and the outside) (JP-A No. 11-283751). 
     In the present invention, it is possible to employ these methods while combined with the organic EL element of the present invention. Of these, it is possible to appropriately employ the method in which a flat layer of a refractive index which is equal to or less than the substrate is introduced between the substrate and the light emitting body and the method in which a diffraction grating is formed between any layers of a substrate, and a transparent electrode layer and a light emitting layer (including between the substrate and the outside space). 
     By combining these means, the present invention enables the production of elements which exhibit higher luminance or excel in durability. 
     When a low refractive index medium having a thickness, greater than the wavelength of light is formed between the transparent electrode and the transparent substrate, the extraction efficiency of light emitted from the transparent electrode to the exterior increases as the refractive index of the medium decreases. 
     As materials of the low refractive index layer, listed are, for example, aerogel, porous silica, magnesium fluoride, and fluorine based polymers. Since the refractive index of the transparent substrate is commonly about 1.5 to 1.7, the refractive index of the low refractive index layer is preferably approximately 1.5 or less. More preferably, it is 1.35 or less. 
     Further, thickness of the low refractive index medium is preferably at least two times of the wavelength in the medium. The reason is that, when the thickness of the low refractive index medium reaches nearly the wavelength of light so that electromagnetic waves escaped via evanescent enter into the substrate, effects of the low refractive index layer are lowered. 
     The method in which the interface which results in total reflection or a diffraction grating is introduced in any of the media is characterized in that light extraction efficiency is significantly enhanced. The above method works as follows. By utilizing properties of the diffraction grating capable of changing the light direction to the specific direction different from diffraction via so-called Bragg diffraction such as primary diffraction or secondary diffraction of the diffraction grating, of light emitted from the light entitling layer, light, which is not emitted to the exterior due to total reflection between layers, is diffracted via introduction of a diffraction grating between any layers or in a medium (in the transparent substrate and the transparent electrode) so that light is extracted to the exterior. 
     It is preferable that the introduced diffraction grating exhibits a two-dimensional periodic refractive index. The reason is as follows. Since light emitted in the light emitting layer is randomly generated to all directions, in a common one-dimensional diffraction grating exhibiting a periodic refractive index distribution only in a certain direction, light which travels to the specific direction is only diffracted, whereby light extraction efficiency is not sufficiently enhanced. 
     However, by changing the refractive index distribution to a two-dimensional one, light, which travels to all directions, is diffracted, whereby the light extraction efficiency is enhanced. 
     A position to introduce a diffraction grating may be between any layers or in a medium (in a transparent substrate or a transparent electrode). However, a position near the organic light emitting layer, where light is generated, is preferable. In this case, the cycle of the diffraction grating is preferably from about ½ to 3 times of the wavelength of light in the medium. The preferable arrangement of the diffraction grating is such that the arrangement is two-dimensionally repeated in the form of a square lattice, a triangular lattice, or a honeycomb lattice. 
     &lt;&lt;Light Collection Sheet&gt;&gt; 
     Via a process to arrange a structure such as a micro-lens array shape on the light extraction side of the organic EL element of the present invention or via combination with a so-called light collection sheet, light is collected in the specific direction such as the front direction with respect to the light emitting element surface, whereby it is possible to enhance luminance in the specific direction. 
     In an example of the micro-lens array, square pyramids to realize a side length of 30 μm and an apex angle of 90 degrees are two-dimensionally arranged on the light extraction side of the substrate. The side length is preferably 10 to 100 μm. When it is less than the lower limit, coloration occurs due to generation of diffraction effects, while when it exceeds the upper limit, the thickness increases undesirably. 
     It is possible to employ, as a light collection sheet, for example, one which is put into practical use in the LED backlight of liquid crystal display devices. It is possible to employ, as such a sheet, for example, the luminance enhancing film (BEF), produced by Sumitomo 3M Limited. As shapes of a prism sheet employed may be, for example, A shaped stripes of an apex angle of 90 degrees and a pitch of 50 μm formed on a base material, a shape in which the apex angle is rounded, a shape in which the pitch is randomly changed, and other shapes. 
     Further, in order to control the light radiation angle from the light emitting element, simultaneously employed may be a light diffusion plate-film. For example, it is possible to employ the diffusion film (LIGHT-UP), produced by Kimoto Co., Ltd. 
     &lt;&lt;Applications&gt;&gt; 
     It is possible to employ the organic EL element of the present invention as display devices, displays, and various types of light emitting sources. 
     Examples of light emitting sources include: lighting apparatuses (home lighting and car lighting), clocks, backlights for liquid crystals, sign advertisements, signals, light sources of light memory media, light sources of electrophotographic copiers, light sources of light communication processors, and light sources of light sensors. The present invention is not limited to them. It is especially effectively employed as a backlight of a liquid crystal display device and a lighting source. 
     If needed, the organic EL element of the present, invention may undergo patterning via a metal mask or an ink-jet printing method during film formation. When the patterning is carried out, only an electrode may undergo patterning, an electrode and a light emitting layer may undergo patterning, or all element layers may undergo patterning. During preparation of the element, it is possible to employ conventional methods. 
     &lt;&lt;Display Device&gt;&gt;

       FIG. 1  is a schematic perspective drawing to show an example of a display device constituted of an organic EL element of the present invention. It displays image information by emission of an organic EL element. An example is a mobile phone. As illustrated in  FIG. 1 , a display 1 is constituted of a display section A having plural number of pixels and a control section B which performs image scanning of the display section A based on image information. 
     The control section B, which is electrically connected to the display section A, sends a scanning signal and an image data signal to plural number of pixels based on image information from the outside and pixels of each scanning line successively emit depending on the image data signal by a scanning signal to perform image scanning, whereby image information is displayed on the display section A.

     Example 1 
     &lt;&lt;Preparation of Organic EL Element&gt;&gt; 
     (1) Preparation of Organic EL Element  101   
     An anode was prepared by making patterning to a glass substrate of 50 mm×50 mm having a thickness of 0.7 mm on which ITO (indium tin oxide) was formed with a thickness of 150 nm. Thereafter, the above transparent support substrate provided with the ITO transparent electrode was subjected to ultrasonic washing with isopropyl alcohol, followed by drying with desiccated nitrogen gas, and was subjected to UV ozone washing for 5 minutes. The resulting transparent support substrate was fixed to a substrate holder of a commercial vacuum deposition apparatus. 
     The constituting materials for each layer were loaded in each resistance heating boat for vapor deposition in the vacuum deposition apparatus with an optimum amount. As a resistance heating boat for vapor deposition, it was used a resistance heating boat made of molybdenum or tungsten. 
     After reducing the pressure of a vacuum tank to 4×10 −4  Pa, the resistance heating boat containing HI-1 was heated via application of electric current and deposition was made onto the ITO transparent electrode at a deposition rate of 0.1 nm/second, whereby it was produced a hole injection layer having a thickness of 15 nm. 
     Subsequently, HT-1 was deposited onto the hole injection layer at a deposition rate of 0.1 nm/second, whereby it was produced a hole transport layer having a thickness of 30 nm. 
     Subsequently, the resistance heating boats each respectively containing the comparative compound 1 as a comparative host compound and GD-1 were heated via application of electric current and co-deposition was made onto the hole transport layer at a deposition rate of 0.1 nm/second and 0.010 nm/second, whereby it was produced a light emitting layer having a thickness of 40 nm. 
     Subsequently, HB-1 was deposited at a deposition rate of 0.1 nm/second, whereby it was produced a first electron transport layer having a thickness of 5 nm. 
     Further, ET-1 was deposited thereon at a deposition rate of 0.1 nm/second, whereby it was produced a second electron transport layer having a thickness of 45 nm. 
     Subsequently, 0.5 nm thick lithium fluoride was vapor deposited, and then, 100 nm thick aluminum was vapor deposited to form a cathode, whereby an organic EL element  101  was prepared. 
     After preparation of the organic EL element, the non-light emitting surface of the prepared organic EL element  101  was covered with a glass cover under the atmosphere of high purity nitrogen gas of 99.999% or more. A glass substrate having a thickness of 300 μm was used as a sealing substrate. As a sealing material, an epoxy-based light curable adhesive (LUXTRACK LC0629B produced by Toagosei Co., Ltd,) was applied to the periphery of the glass cover. The resulting one was superimposed on the cathode side to be brought into close contact with the transparent support substrate. Curing and sealing were carried out via exposure of UV radiation onto the glass substrate side, whereby the lighting device having the constitution illustrated in  FIG. 3  and  FIG. 4  was formed. This was used as a sample for evaluation. 
     &lt;&lt;Preparation of Organic EL Elements  102  to  111 &gt;&gt; 
     Organic EL elements  102  to  111  were prepared in the same manner as preparation of the organic EL element  101  except that the host compound was changed as indicated in Table 1. After preparation, the lighting devices having the constitution as illustrated in  FIG. 3  and  FIG. 4  were prepared. They were used for samples. 
     &lt;&lt;Evaluation of Organic EL Elements  101  to  111 &gt;&gt; 
     The prepared samples were subjected to the evaluations as described below. The evaluation results are listed in Table 1. 
     (1) External Taking Out Quantum Efficiency 
     Each organic EL element was allowed to emit light with a constant electric current of 2.5 mA/cm.sup.2 at room temperature (at about 23° C.). The external taking out quantum efficiency (η) was determined by measuring the luminance (L0) (cd/m 2 ) measured immediately after starting to emit light. 
     Here, the measurement of luminance was done with a spectroradiometer CS-2000 (produced by Konica Minolta Inc.). The external taking out quantum efficiency was represented by a relative value when the external quantum efficiency of the organic EL element  101  was set to be 100. 
     When the value is larger, it indicates that the light emitting efficiency is better. 
     (2) Half Lifetime 
     Evaluation of half Lifetime was done according to the following measuring method. 
     The prepared organic EL element was driven with a constant electric current to give an initial luminance of 4,000 cd/m 2 . 
     The time required for decease in one half of the initial luminance was determined, and it was used as a scale for a half lifetime. The emission lifetime was represented as a relative value when the emission lifetime of the organic EL element  101  was set to be 100. 
     When the value is larger, it indicates that the durability is better compared with the comparative sample. 
     (3) Evaluation of High-Temperature Storage Stability 
     The prepared organic EL element was placed in a thermostat oven under a high-temperature condition (about 50±5° C.). The evaluation of half lifetime in the same manner as described in (2) was carried out. The heat resistance was calculated by using the following scheme. 
       Heat resistance(%)=[(Half lifetime under a high-temperature condition)/(Half lifetime at room temperature)]×100
 
     In Table 1, the heat resistance was represented as a relative value when the heat resistance of the organic EL element  101  was set to be 100. When the heat resistance is larger, it indicates that the resistance against temperature change is better compared with the comparative sample. That is, the larger the heat resistance, the excellent the high-temperature storage stability.

     &lt;&lt;Preparation of Organic EL Element&gt;&gt; 
     (1) Preparation of Organic EL Element  201   
     An anode was prepared by making patterning to a glass substrate of 50 mm×50 mm having a thickness of 0.7 mm on which ITO (indium tin oxide) was formed with a thickness of 150 nm. Thereafter, the above transparent support substrate provided with the ITO transparent electrode was subjected to ultrasonic washing with isopropyl alcohol, followed by drying with desiccated nitrogen gas, and was subjected to UV ozone washing for 5 minutes. The resulting transparent support substrate was fixed to a substrate holder of a commercial vacuum deposition apparatus. 
     The constituting materials for each layer were loaded in each resistance heating boat for vapor deposition in the vacuum deposition apparatus with an optimum amount. As a resistance heating boat for vapor deposition, it was used a resistance heating boat made of molybdenum or tungsten. 
     After reducing the pressure of a vacuum tank to 4×10 −4  Pa, the resistance heating boat containing HI-2 was heated via application of electric current and deposition was made onto the ITO transparent electrode at a deposition rate of 0.1 nm/second, whereby it was produced a hole injection layer having a thickness of 10 nm. 
     Subsequently, HT-2 was deposited onto the hole injection layer at a deposition rate of 0.1 nm/second, whereby it was produced a hole transport layer having a thickness of 30 nm. 
     Subsequently, the resistance heating boats each respectively containing the comparative compound 2 as a comparative host compound and GD-2 were heated via application of electric current and co-deposition was made onto the hole transport layer at a deposition rate of 0.1 nm/second and 0.010 nm/second, whereby it was produced a light emitting layer having a thickness of 30 nm. 
     Subsequently, HB-2 was deposited at a deposition rate of 0.1 nm/second, whereby it was produced a first electron transport layer having a thickness of 5 nm. 
     Further. ET-2 was deposited thereon at a deposition rate of 0.1 nm/second, whereby it was produced a second electron transport layer having a thickness of 45 nm. 
     Subsequently, 0.5 nm thick lithium fluoride was vapor deposited, and then, 100 nm thick aluminum was vapor deposited to form a cathode, whereby an organic EL element  201  was prepared. 
     After preparation of the organic EL element, the non-light emitting surface of the prepared organic EL element  201  was covered with a glass cover under the atmosphere of high purity nitrogen gas of 99.999% or more. A glass substrate having a thickness of 300 μm was used as a sealing substrate. As a sealing material, an epoxy-based light curable adhesive (LUXTRACK LC0629B produced by Toagosei Co., Ltd,) was applied to the periphery of the glass cover. The resulting one was superimposed on the cathode side to be brought into close contact with the transparent support substrate. Curing and sealing were carried out via exposure of UV radiation onto the glass substrate side, whereby the lighting device having the constitution as illustrated in  FIG. 3  and  FIG. 4  was formed. This was used as a sample for evaluation. 
     &lt;&lt;Preparation of Organic EL Elements  202  to  212 &gt;&gt; 
     Organic EL elements  202  to  212  were prepared in the same manner as preparation of the organic EL element  201  except that the host compound was changed as indicated in Table 2. After preparation, the lighting devices having the constitution as illustrated in  FIG. 3  and  FIG. 4  were prepared. They were used for samples. 
     &lt;&lt;Evaluation of Organic EL Elements  201  to  212 &gt;&gt; 
     The prepared samples were subjected to the evaluations as described below. 
     With respect to external taking out quantum efficiency, half lifetime, and evaluation of high-temperature storage stability, evaluations were made in the same ways as in Example 1. The evaluation results were represented as a relative value when the results of the organic EL element  201  were set to be 100. 
     The evaluation results are listed in Table 2.

     Example 3 
     &lt;&lt;Preparation of Organic EL Element&gt;&gt; 
     (1) Preparation of Organic EL Element  301   
     An anode was prepared by making patterning to a glass substrate of 50 mm×50 mm having a thickness of 0.7 mm on which ITO (indium tin oxide) was formed with a thickness of 150 nm. Thereafter, the above transparent support substrate provided with the ITO transparent electrode was subjected to ultrasonic washing with isopropyl alcohol, followed by drying with desiccated nitrogen gas, and was subjected to UV ozone washing for 5 minutes. The resulting transparent support substrate was fixed to a substrate holder of a commercial vacuum deposition apparatus. 
     The constituting materials for each layer were loaded in each resistance heating boat for vapor deposition in the vacuum deposition apparatus with an optimum amount. As a resistance heating boat for vapor deposition, it was used a resistance heating boat made of molybdenum or tungsten. 
     After reducing the pressure of a vacuum tank to 4×10 −4  Pa, the resistance heating boat containing HI-2 was heated via application of electric current and deposition was made onto the ITO transparent electrode at a deposition rate of 0.1 nm/second, whereby it was produced a hole injection layer having a thickness of 20 nm. 
     Subsequently, HT-1 was deposited onto the hole injection layer at a deposition rate of 0.1 nm/second, whereby it was produced a hole transport layer having a thickness of 20 nm. 
     Subsequently, the resistance heating boats each respectively containing the comparative compound 3 as a comparative host compound and GD-3 were heated via application of electric current and co-deposition was made onto the hole transport layer at a deposition rate of 0.1 nm/second and 0.010 nm/second, whereby it was produced a light emitting layer having a thickness of 30 nm. 
     Subsequently, HB-3 was deposited at a deposition rate of 0.1 nm/second, whereby it was produced a first electron transport layer having a thickness of 10 nm. 
     Further, ET-2 was deposited thereon at a deposition rate of 0.1 nm/second, whereby it was produced a second electron transport layer having a thickness of 40 nm. 
     Subsequently, 0.5 nm thick lithium fluoride was vapor deposited, and then, 100 nm thick aluminum was vapor deposited to form a cathode, whereby an organic EL element  301  was prepared. 
     After preparation of the organic EL element, the non-light emitting surface of the prepared organic EL element  301  was covered with a glass cover under the atmosphere of high purity nitrogen gas of 99.999% or more. A glass substrate having a thickness of 300 μm was used as a sealing substrate. As a sealing material, an epoxy-based light curable adhesive (LUXTRACK LC0629B produced by Toagosei Co., Ltd,) was applied to the periphery of the glass cover. The resulting one was superimposed on the cathode side to be brought into close contact with the transparent support substrate. Curing and sealing were carried out via exposure of UV radiation onto the glass substrate side, whereby the lighting device having the constitution as illustrated in  FIG. 3  and  FIG. 4  was formed. This was used as a sample for evaluation. 
     &lt;&lt;Preparation of Organic EL Elements  302  to  312 &gt;&gt; 
     Organic EL elements  302  to  312  were prepared in the same manner as preparation of the organic EL element  301  except that the host compound was changed as indicated in Table 3. After preparation, the lighting devices having the constitution as illustrated in  FIG. 3  and  FIG. 4  were prepared. They were used for samples. 
     &lt;&lt;Evaluation of Organic EL Elements  301  to  312 &gt;&gt; 
     The prepared samples were subjected to the evaluations as described below. 
     With respect to external taking out quantum efficiency, half lifetime, and evaluation of high-temperature storage stability, evaluations were made in the same ways as in Example 1. The evaluation results were represented as a relative value when the results of the organic EL element  301  were set to be 100. 
     The evaluation results are listed in Table 3.

     From the results in Table 4, it is clear that the organic EL elements  402  to  412  of the present invention are excellent in external taking out quantum efficiency, half lifetime, and high-temperature storage stability compared with the comparative organic EL element  401 . 
     Example 5 
     &lt;&lt;Preparation of Organic EL Element&gt;&gt; 
     (1) Preparation of Organic EL Element  501   
     An anode was prepared by making patterning to a glass substrate of 50 mm×50 mm having a thickness of 0.7 mm on which ITO (indium tin oxide) was formed with a thickness of 120 nm. Thereafter, the above transparent support substrate provided with the ITO transparent electrode was subjected to ultrasonic washing with isopropyl alcohol, followed by drying with desiccated nitrogen gas, and was subjected to UV ozone washing for 5 minutes. 
     On the transparent support substrate thus prepared was applied a 70% solution of poly (3,4-ethylenedioxythiphene)-polystyrene sulfonate (PEDOT/PSS, Baytron P AI4083, made by Bayer AG) diluted with water by using a spin coating method at 3,000 rpm for 30 seconds to form a film, and then it was dried at 200° C. for one hour. A hole injection layer having a thickness of 20 nm was prepared. 
     Then, the resulting transparent support substrate was fixed to a substrate holder of a commercial vacuum deposition apparatus. 
     The constituting materials for each layer were loaded in each resistance heating boat for vapor deposition in the vacuum deposition apparatus with an optimum amount. As a resistance heating boat for vapor deposition, it was used a resistance heating boat made of molybdenum or tungsten. 
     After reducing the pressure of a vacuum tank to 4×10 −4  Pa, the resistance heating boat containing HI-4 was heated via application of electric current and deposition was made onto the ITO transparent electrode at a deposition rate of 0.1 nm/second, whereby it was produced a hole transport layer having a thickness of 20 nm. 
     Subsequently, the resistance heating boats each respectively containing the comparative compound 1 as a comparative host compound and GD-1 were heated via application of electric current and co-deposition was made onto the hole transport layer at a deposition rate of 0.1 nm/second and 0.010 nm/second, whereby it was produced a light emitting layer having a thickness of 40 nm. 
     Subsequently, HB-1 was deposited at a deposition rate of 0.1 nm/second, whereby it was produced a first electron transport layer having a thickness of 5 nm. 
     Further. ET-3 was deposited thereon at a deposition rate of 0.1 nm/second, whereby it was produced a second electron transport layer having a thickness of 30 nm. 
     Subsequently, 0.5 nm thick lithium fluoride was vapor deposited, and then, 100 nm thick aluminum was vapor deposited to form a cathode, whereby an organic EL element  501  was prepared. 
     After preparation of the organic EL element, the non-light emitting surface of the prepared organic EL element  501  was covered with a glass cover under the atmosphere of high purity nitrogen gas of 99.999% or more. A glass substrate having a thickness of 300 μm was used as a sealing substrate. As a sealing material, an epoxy-based light curable adhesive (LUXTRACK LC0629B produced by Toagosei Co., Ltd) was applied to the periphery of the glass cover. The resulting one was superimposed on the cathode side to be brought into close contact with the transparent support substrate. Curing and sealing were carried out via exposure of UV radiation onto the glass substrate side, whereby the lighting device having the constitution as illustrated in  FIG. 3  and  FIG. 4  was formed. This was used as a sample for evaluation. 
     &lt;&lt;Preparation of Organic EL Elements  502  to  512 &gt;&gt; 
     Organic EL elements  502  to  512  were prepared in the same manner as preparation of the organic EL element  501  except that the host compound was changed as indicated in Table 5. After preparation, the lighting devices having the constitution as illustrated in  FIG. 3  and  FIG. 4  were prepared. They were used for samples. 
     &lt;&lt;Evaluation of Organic EL Elements  501  to  512 &gt;&gt; 
     The prepared samples were subjected to the evaluations as described below. 
     With respect to external taking out quantum efficiency, half lifetime, and evaluation of high-temperature storage stability, evaluations were made in the same ways as in Example 1. The evaluation results were represented as a relative value when the results of the organic EL element  501  were set to be 100. 
     The evaluation results are listed in Table 5.

     &lt;&lt;Preparation of Full-Color Display Device&gt;&gt; 
     (1) Blue Color Emitting Element 
     &lt;&lt;Preparation of Organic EL Element  1301 &gt;&gt; 
     An anode was prepared by making patterning to a glass substrate of 100 mm×100 mm×1.1 mm (NA45, produced by NH Techno Glass Corp.) on which ITO (indium tin oxide) was formed with a thickness of 100 nm. Thereafter, the above transparent support substrate provided with the ITO transparent electrode was subjected to ultrasonic washing with isopropyl alcohol, followed by drying with desiccated nitrogen gas, and was subjected to UV ozone washing for 5 minutes. 
     The resulting transparent support substrate was fixed to a substrate holder of a commercial vacuum deposition apparatus. Separately, 200 mg of HT-1 was placed in a molybdenum resistance heating boat, 200 mg of mCP (1,3-bis-N-carbazolylbenzene) as a host compound was placed in another molybdenum resistance heating boat, 200 mg of HB-2 was placed in another molybdenum resistance heating boat, 100 mg of BD-1 as a light emitting dopant was placed in another molybdenum resistance heating boat, and 200 mg of ET-2 was placed in another molybdenum resistance heating boat. The resulting boats were fitted in the vacuum deposition apparatus. 
     Subsequently, after reducing the pressure of a vacuum tank to 4×10 −4  Pa, the heating boat containing HT-1 was heated via application of electric current and deposition was made onto the transparent support substrate at a deposition rate of 0.1 nm/second, whereby it was produced a hole transport layer having a thickness of 40 nm. 
     Subsequently, the molybdenum resistance heating boats each respectively containing mCP (1,3-bis-N-carbazolylbenzene) and BD-1 were heated via application of electric current and co-deposition was made onto the hole transport layer at a deposition rate of 0.2 nm/second and 0.012 nm/second, whereby it was produced a light emitting layer having a thickness of 40 nm. The substrate temperature was made to be room temperature during the deposition process. 
     Further, the molybdenum resistance heating boat containing HB-2 was heated via application of electric current, and deposition was made onto the light emitting layer at a deposition rate of 0.1 nm/second, whereby it was produced a hole blocking layer having a thickness of 10 nm. 
     Further, the molybdenum resistance heating boat containing ET-2 was heated via application of electric current, and deposition was made onto the hole blocking layer at a deposition rate of 0.1 nm/second, whereby it was produced an electron transport layer having a thickness of 10 nm. The substrate temperature was made to be room temperature during the deposition process. 
     Subsequently, 0.5 nm thick lithium fluoride was vapor deposited, and then, 110 nm thick aluminum was vapor deposited to form a cathode, whereby an organic EL element  1301  was prepared. 
     After preparation of the organic EL element, the non-light emitting surface of the prepared organic EL element  1301  was covered with a glass cover under the atmosphere of high purity nitrogen gas of 99.999% or more. A glass substrate having a thickness of 300 μm was used as a sealing substrate. As a sealing material, an epoxy-based light curable adhesive (LUXTRACK LC0629B produced by Toagosei Co., Ltd,) was applied to the periphery of the glass cover. The resulting one was superimposed on the cathode side to be brought into close contact with the transparent support substrate. Curing and sealing were carried out via exposure of UV radiation onto the glass substrate side, whereby the lighting device having the constitution as illustrated in  FIG. 3  and  FIG. 4  was formed. This was used as a sample for evaluation. 
     (2) Green Color Emitting Element 
     The organic EL element in Example 5 was used as a green color emitting element. 
     (3) Red Color Emitting Element 
     &lt;&lt;Preparation of Organic EL Element  1302 &gt;&gt; 
     An organic EL element  1302  that is a red color emitting element was prepared in the same manner as preparation of the organic EL element  1301  that is a blue color emitting element except that the light emitting dopant GD-1 was replaced with RD-1. 
     (4) Preparation of Display Device 
     The red color, green color and blue color emitting organic EL elements were arranged in a line on the same substrate. It was prepared a full-color display device with an active matrix mode and having the structure as illustrated in  FIG. 1 . 
       FIG. 2  is a schematic drawing illustrating only a display section A of the prepared display device. 
     As illustrated in  FIG. 2 , the display section A has: a wiring section containing plural scanning lines  5  and data lines  6 , and plural pixels  3  (such as a pixel having an emission color of a red region, a pixel of a green region and a pixel of a blue region) arranged in parallel provided on the same substrate. The scanning lines  5  and data lines  6  in the wiring section, which are respectively composed of a conductive material, cross each other at a right angle in a grid form and are connected to the pixels  3  at the right-angled crossing points (details are not shown in the drawing). 
     The plural pixels  3  each are operated in an active matrix mode provided with a switching transistor and an operating transistor, both being an active element, and organic EL elements corresponding to each emission color. The plural pixels  3  receive an image data signal from the date line  6  when a scanning signal is applied from the scanning line  5  to emit based on the received image data. Each red, green and blue pixel  3  was suitably arranged in parallel in this manner, whereby a full-color display device was prepared. 
     It has been confirmed that the obtained full-color display device exhibited a full-color moving image having a high luminance, a high durability, and excellent in storage stability at high-temperature when it was driven.
