Title: Display device and method for manufacturing same

Description:
TECHNICAL FIELD 
     The present invention relates to a display included in, for example, a television and a method of manufacturing the same. 
     BACKGROUND ART 
     In recent years, for example, displays such as those including liquid crystal and an organic EL (electroluminescence) are used as a display monitor for a flat television, a notebook personal computer, a car navigation, and the like. In such a display, it is known that a front plate formed of a transparent substrate such as plastic and glass is provided on a front surface side (a display side) of the display panel, in terms of surface protection and design (for example, see PTLs 1 to 4). 
     In PTL 1, to prevent image quality degradation caused by interface reflection, it is proposed that a transparent material adjusted in refractive index is interposed between the front plate and the display panel. In addition, in PTLs 2 to 4, for example, liquid, a gel sheet, an adhesive sheet, and photocurable resin are used as such a transparent material. 
     For example, in the case of using photocurable resin of the above-described transparent materials, after the photocurable resin is sandwiched between the display panel and the front plate, the resin material is cured by light application from the front plate side. Using the photocurable resin eliminates concern such as leakage compared with a liquid material, and makes it difficult for dust and air bubbles to enter at the time of manufacturing compared with an adhesive sheet. Further, it becomes possible to bond the display panel to the front plate without being affected by distortion, a step structure, etc. of the display panel and the front plate. 
     On the other hand, in the front plate, a region facing a non-display section (a bezel section) of the display panel is subjected to light shielding processing in some cases, in terms of image quality enhancement and design. Specifically, a light shielding layer is formed by, for example, evaporating or printing a light shielding material or bonding an opaque sheet material to a frame-like region along the outer edge of the front plate.

     SUMMARY OF INVENTION 
     However, in the case where a resin layer formed of photocurable resin is interposed between the front plate and the display panel and the above-described frame-like light shielding layer is formed on the front plate, the following defects have occurred. Specifically, in such a case, in the manufacturing process, light is applied from a side of a front plate provided with the light shielding layer to cure the resin material, and thus the resin on a backside of the light shielding layer is remained in an uncured state, and liquid of uncured resin may be leaked after application. 
     The present invention is made in view of the above disadvantages, and it is an object of the present invention to provide a display capable of suppressing curing failure of a resin layer on a backside of a light shielding layer and a method of manufacturing the display. 
     A first display according to the present invention includes the following components (A) to (E):
     (A) a display panel including a display region and a non-display region, the display region including a plurality of pixels, and the non-display region surrounding the display region;   (B) a resin layer provided on a front surface of the display panel and formed of a photocurable resin, the resin having a refractive index higher than a refractive index of the transparent substrate before and after curing in a wavelength range of light used for curing;   (C) a transparent substrate provided on a front surface of the resin layer;   (D) an intermediate layer provided on a front surface of the transparent substrate and having a refractive index lower than the refractive index of the transparent substrate in the wavelength range of the light used for curing the resin; and   (E) a light shielding layer provided in a region of a front surface of the intermediate layer, the region facing the non-display region.   

     In the first display of the present invention, the light applied for curing the resin in the manufacturing process enters the transparent substrate from the front surface or the side surface thereof. Since the intermediate layer that has the refractive index lower than that of the transparent substrate in the wavelength range of the light used for curing the resin is provided on the front surface of the transparent substrate, the light entering from the side surface of the transparent substrate is totally reflected by an interface between the transparent substrate and the intermediate layer, and is then guided through the transparent substrate. In addition, since the light shielding layer is provided on the front surface of the intermediate layer, the light is not absorbed by the light shielding layer. Further, since the resin layer is formed of a resin that has a refractive index higher than the refractive index of the transparent substrate before and after curing in the wavelength range of the light used for curing, the light enters the resin layer from the transparent substrate to cure the resin. Consequently, curing failure of the resin layer on a backside of the light shielding layer is suppressed. 
     A second display according to the present invention includes the following components (A) to (D):
     (A) a display panel including a display region and a non-display region, the display region including a plurality of pixels, and the non-display region surrounding the display region;   (B) a resin layer provided on a front surface of the display panel and formed of a photocurable resin, the resin having a refractive index higher than a refractive index of a transparent substrate before and after curing in a wavelength range of light used for curing;   (C) a transparent substrate provided on a front surface of the resin layer; and   (D) a light shielding layer provided in a region of a front surface of the transparent substrate, the region facing the non-display region, and the light shielding layer having a refractive index lower than the refractive index of the transparent substrate in the wavelength range of the light used for curing the resin.   

     In the second display of the present invention, the light applied for curing the resin in the manufacturing process enters the transparent substrate from the front surface or the side surface thereof. In a region of the front surface of the transparent substrate facing the non-display region, since the light shielding layer that has the refractive index lower than that of the transparent substrate in the wavelength range of the light used for curing the resin is provided, the light entering from the side surface of the transparent substrate is totally reflected by an interface between the transparent substrate and the light shielding layer, and is then guided through the transparent substrate. In addition, since the light shielding layer is provided on the front surface of the transparent substrate, the light is not absorbed by the light shielding layer. Further, since the resin layer is formed of a resin that has a refractive index higher than the refractive index of the transparent substrate before and after curing in the wavelength range of the light used for curing, the light enters the resin layer from the transparent substrate to cure the resin. Consequently, curing failure of the resin layer on the backside of the light shielding layer is suppressed. 
     A first method of manufacturing a display according to the present invention includes the following steps (A) to (D):
     (A) providing a transparent substrate on a front surface of a display panel with a photocurable resin in between, the display panel including a display region and a non-display region, the display region including a plurality of pixels, the non-display region surrounding the display region, and using, as the resin, a resin having a refractive index higher than a refractive index of the transparent substrate before and after curing in a wavelength range of light used for curing;   (B) providing an intermediate layer on a front surface of the transparent substrate, the intermediate layer having a refractive index lower than the refractive index of the transparent substrate in the wavelength range of the light used for curing the resin;   (C) providing a light shielding layer in a region of a front surface of the intermediate layer facing the non-display region; and   (D) forming a resin layer by applying light from a front surface side and a side surface side of the display panel to cure the resin.   

     A second method of manufacturing a display according to the present invention includes the following steps (A) to (C):
     (A) providing a transparent substrate on a front surface of a display panel with a photocurable resin in between, the display panel including a display region and a non-display region, the display region including a plurality of pixels, the non-display region surrounding the display region, and using, as the resin, a resin having a refractive index higher than a refractive index of the transparent substrate before and after curing in a wavelength range of light used for curing;   (B) providing a light shielding layer in a region of a front surface of the transparent substrate facing the non-display region, the light shielding layer having a refractive index lower than the refractive index of the transparent substrate in the wavelength range of the light used for curing the resin; and   (C) forming a resin layer by applying light from a front surface side and a side surface side of the display panel to cure the resin.   

     According to the first display of the present invention or the first method of manufacturing the display of the present invention, the resin layer is formed of a resin that has a refractive index higher than the refractive index of the transparent substrate before and after curing in the wavelength range of the light used for curing, as well as the intermediate layer that has a refractive index lower than that of the transparent substrate in the wavelength range of the light used for curing the resin is provided on the surface of the transparent substrate and the light shielding layer is provided on the front surface of the intermediate layer. Accordingly, the level relationship between the refractive indices of the resin layer, the transparent substrate, and the intermediate layer is optimally adjusted, and curing failure of the resin layer on the backside of the light shielding layer is suppressed. 
     According to the second display of the present invention or the second method of manufacturing the display of the present invention, the resin layer is formed of a resin that has a refractive index higher than the refractive index of the transparent substrate before and after curing in the wavelength range of the light used for curing, as well as the light shielding layer that has a refractive index lower than that of the transparent substrate in the wavelength range of the light used for curing the resin is provided in a region of the front surface of the transparent substrate facing the non-display region. Accordingly, the level relationship between the refractive indices of the resin layer, the transparent substrate, and the light shielding layer is optimally adjusted, and curing failure of the resin layer on the backside of the light shielding layer is suppressed.

Examples   

     First Embodiment 
       FIG. 1  schematically illustrates a cross-sectional configuration of a display according to a first embodiment of the present invention. The display  1  is a liquid crystal display used as a display monitor of, for example, a television, a notebook personal computer, and a car navigation, and includes a resin layer  20 , a transparent substrate  30 , an intermediate layer  40 , and a light shielding layer  50  in this order on a front surface side (light emission side) of a display panel  10 . A backlight unit  60  is provided on a back surface side (light incident side) of the display panel  10 . The display panel  10  and the backlight unit  60  are disposed in an exterior member  70 . 
     The display panel  10  is a liquid crystal display panel displaying a picture based on illumination light from the backlight unit  60 , and is of an active matrix system displaying a picture for each pixel by a drive signal supplied from a gate driver (not illustrated), based on a picture signal transmitted from a data driver (not illustrated). The display panel  10  is configured by sealing a not-illustrated liquid crystal layer between a drive substrate  10 A and a counter substrate  10 B. A polarizing plate  11 A is bonded to an outside surface of the drive substrate  10 A and a polarizing plate  11 B is bonded to an outside surface of the counter substrate  10 B. On the drive substrate  10 A, a TFT (Thin Film Transistor) driving each pixel is disposed on, for example, a glass substrate, and a drive circuit supplying a picture signal and the like to each pixel, a wiring substrate for external connection, and the like are provided. The counter substrate  10 B is configured by forming not-illustrated color filters of three primary colors (R, G, and B) for each pixel on, for example, a glass substrate. The liquid crystal layer used includes nematic liquid crystal of VA (Vertical Alignment) mode, TN (Twisted Nemtatic) mode, IPS (In Plane Switching) mode, and the like. Note that the drive substrate  10 A and the counter substrate  10 B are not necessarily provided in this order. Moreover, the color filters may not be particularly provided, or alternatively, the color filters may be provided not on the counter substrate  10 B but on the drive substrate  10 A. Further, a drive device other than a TFT may be used. 
       FIG. 2  illustrates a plane configuration of the display  1  illustrated in  FIG. 1  as viewed from the light shielding layer  50  side. In the display panel  10 , a non-display region B (a frame-like region between a boundary a 1  and an edge a 2  of the display panel  10 ) is provided around a display region A (a rectangular region surrounded by the boundary al). A plurality of pixels are arranged in a matrix in the display region A, and the drive circuit for driving the pixels, the wiring substrate for external connection, and the like are provided in the non-display region B. 
     The resin layer  20  has a function to suppress interface reflection between the display panel  10  and the transparent substrate  30 , and is provided to improve impact resistance. The resin layer  20  is formed of a silicone resin, an epoxy resin, an acrylic resin, or the like that is cured by, for example, ultraviolet light or visible light, and is preferably formed of an acrylic resin. As the acrylic resin, a resin composition containing an oligomer, an acrylic monomer, a photopolymerization initiator, a plasticizer, and the like is desirable. Examples of the oligomer include polyurethane acrylate, polyisoprene acrylate, polyesteracrylate, and epoxyacrylate. As the acrylic monomer, monofunctional acrylic monomer such as isobornyl acrylate, benzyl acrylate, and 2-hydroxyethyl methacrylate is preferable. 
     Such a resin layer  20  desirably has a cure shrinkage at the time of resin curing of 2% or less, and desirably has a storage elastic modulus after resin curing of 1.0×10 6  Pa or less in order to suppress display unevenness. 
     The resin layer  20  desirably has a thickness of 20 μm to 5 mm, and more desirably 20 μm to 500 μm. If the thickness of the resin layer  20  is smaller than 20 μm, bonding strength is lowered or manufacturability is impaired. On the other hand, if the thickness of the resin layer  20  is larger than 500 μm, a sense of depth of image quality becomes remarkable, design is degraded, cost is increased due to increase in the use of resin materials, and further, the weight of the entire display  1  is increased. 
     The transparent substrate  30  is a so-called front plate that is provided to protect the surface of the display panel  10  and to improve design. The transparent substrate  30  has a thickness of, for example, 0.2 mm to 5.0 mm, and is formed of glass or plastic. Examples of the plastic include acryl and polycarbonate. Incidentally, a glass material is desirably used particularly for a large display in terms of dimensional stability. In addition, a surface on the front surface side (observing side, light emission side) of the transparent substrate  30  is preferably subjected to non-reflection treatment or low-reflection treatment. 
     The external dimensions of the transparent substrate  30  is larger than the external dimensions of the display panel  10 , and the edge b 2  of the transparent substrate  30  hangs over by, for example, about 5 mm to about 100 mm toward the outside from the edge a 2  of the display panel  10 . 
     The intermediate layer  40  is formed of a transparent resin material on the front surface (a surface on the light emission side)  30 A of the transparent substrate  30 . Incidentally, the intermediate layer  40  may be provided on the entire front surface  30 A of the transparent substrate  30 , or may be provided only under the light shielding layer  50 . A rectangular region of the intermediate layer  40  or the transparent substrate  30  facing the display region A is a light transmissive section A 1  for transmitting display light. 
     The light shielding layer  50  is provided in a frame-like region of the front surface  40 A of the intermediate layer  40  facing the non-display region B in order to improve image quality and design. The light shielding layer  50  has a thickness of, for example 0.1 μm to 100 μm, and is formed of an opaque material such as carbon black, metal, pigment, and dye. The edge b 1  on the inner side of the light shielding layer  50  is preferably located outside of the boundary a 1  between the display region A and the non-display region B of the display panel  10 . This makes it possible to prevent the pixels of the display panel  10  from being hidden by the light shielding layer  50  when the display  1  is viewed from an oblique direction. 
     Further, in the present embodiment, the resin layer  20  is formed of a resin that has a refractive index higher than a refractive index of the transparent substrate  30  before curing (in a liquid state) and after curing (in a solid state) in the wavelength range of the light used for curing. The intermediate layer  40  has a refractive index lower than that of the transparent substrate  30  in the wavelength range of the light used for curing the resin configuring the resin layer  20 . Therefore, in the display  1 , it is possible to suppress curing failure of the resin layer  20  on the back side of the light shielding layer  50 . 
       FIG. 3  and  FIG. 4  each illustrate a specific configuration example of the transparent substrate  30 , the intermediate layer  40 , and the light shielding layer  50 . For example, in  FIG. 3 , the intermediate layer  40  is provided on the entire front surface  30 A of the transparent substrate  30 , and the light shielding layer  50  is provided in a region of the front surface  40 A of the intermediate layer  40  facing the non-display region B. The intermediate layer  40  is formed by, for example, coating a transparent resin material that has a refractive index lower than that of the transparent substrate  30  in the wavelength range of the light used for curing the resin configuring the resin layer  20 . The light shielding layer  50  is formed by printing or evaporating the above-described opaque material, for example. 
     In addition, for example, in  FIG. 4 , a transparent film  51  is bonded to the entire front surface  30 A of the transparent substrate  30  with the intermediate layer  40  serving also as an adhesive layer in between. The light shielding layer  50  is provided by printing or the like, in a region of the transparent film  51  facing a non-emission region B. The intermediate layer  40  is formed of a transparent adhesive agent that has a refractive index lower than that of the transparent substrate  30  in the wavelength range of the light used for curing the resin configuring the resin layer  20 . 
     The backlight unit  60  illustrated in  FIG. 1  illuminates the display panel  10  from backside thereof directly or through an optical member such as a light guide plate, using a fluorescent tube such as a CCFL (Cold Cathode Fluorescent Lamp), a light emitting diode (LED), and the like as a light source. 
     The display  1  may be manufactured in the following way, for example. 
       FIG. 5  and  FIG. 6  illustrate a part of the method of manufacturing the display  1  in process order. First, as illustrated in  FIG. 5A , the display panel  10  is fabricated. Specifically, the drive substrate  10 A provided with the TFT, the drive circuit, and the like is bonded to the counter substrate  10 B having the color filters with a not-illustrated liquid crystal layer in between, and then the polarizing plate  11 A is bonded to the outside surface of the drive substrate  10 A and the polarizing plate  11 B is bonded to the outside surface of the counter substrate  10 B. 
     On the other hand, as illustrated in  FIG. 5B , the intermediate layer  40  and the light shielding layer  50  are formed in this order on the front surface  30 A of the transparent substrate  30 . At this time, the intermediate layer  40  is so formed as to have the refractive index lower than that of the transparent substrate  30  in the wavelength range of the light used for curing the resin of the resin layer  20 . 
     To be more specific, for example, as illustrated in  FIG. 3 , the entire front surface  30 A of the transparent substrate  30  is coated with a transparent resin material that has a refractive index lower than that of the transparent substrate  30  in the wavelength range of the light used for curing the resin configuring the resin layer  20  to form the intermediate layer  40 . After that, for example, the above-described opaque material is dispersed or dissolved in a binder and is printed or directly evaporated on the front surface  40 A of the intermediate layer  40  to provide the light shielding layer  50 . 
     Alternatively, for example, as illustrated in  FIG. 4 , the transparent film  51  on which the light shielding layer  50  is printed is bonded to the entire front surface  30 A of the transparent substrate  30  with the intermediate layer  40  serving also as an adhesive layer in between. The intermediate layer  40  is formed of a transparent adhesive agent that has a refractive index lower than that of the transparent substrate  30  in the wavelength range of the light used for curing the resin configuring the resin layer  20 . 
     Note that the front surface (the surface on the observing side) of the transparent substrate  30  is preferably subjected to non-reflection treatment or low-reflection treatment. These treatments may be performed by evaporation or coating of a non-reflection material or a low-reflection material, or bonding of a non-reflection film, a low-reflection film, or the like. 
     Subsequently, as illustrated in  FIG. 6 , the display panel  10  and the transparent substrate  30  fabricated in the above-described way are overlaid with the photocurable resin  21  in between, and light L in the wavelength range curing the resin  21 , for example, ultraviolet light or visible light, is applied from the front surface  30 A side of the transparent substrate  30 . Specifically, it is sufficient to use light having a photosensitive wavelength in a photoinitiator contained in the resin  21 . In terms of productivity, however, a lamp with emission center of 365 nm or 405 nm, an LED having such an emission wavelength, or the like is preferably used. In addition, although it is only necessary to set the illuminance and the amount of the light L depending on the composition, the thickness, and the like of the resin material used for the resin  21 , desirably, integral of light is set within a range of 1500 to 15000 mL/cm 2 , and the illuminance is set within a range of 10 to 500 mW/cm 2 . 
     Moreover, also as illustrated in  FIG. 6 , the light L is applied from a side surface  30 B side of the transparent substrate  30  at the same time as the light L is applied from the front surface  30 A side of the transparent substrate  30 . Incidentally, the process of applying the light L from the side surface  30 B side of the transparent substrate  30  may be performed at the same time as application from the front surface  30 A side, or may be performed before or after application from the front surface  30 A side. 
       FIG. 7  illustrates a backside of the light shielding layer  50  illustrated in  FIG. 6  in an enlarged manner. As illustrated in  FIG. 7 , the light L applied from the side surface  30 B side enters the transparent substrate  30  from an end surface thereof or from a bonding section of the transparent substrate  30  and the display panel  10 . Since an entering angle is extremely shallow, the light L cures the resin  21  on the backside of the light shielding layer  50  while being guided through the transparent substrate  30 , to form the resin layer  20 . 
     To be more specific, on the front surface  30 A of the transparent substrate  30  (an interface between the transparent substrate  30  and the intermediate layer  40 ), since the refractive index of the intermediate layer  40  is lower than that of the transparent substrate  30  in the wavelength range of the light L used for curing the resin  21 , the light L is totally reflected. On the other hand, on a back surface  30 C of the transparent substrate  30  (an interface between the transparent substrate  30  and the resin  21 ), the refractive index of the resin  21  before and after curing is higher than the refractive index of the transparent substrate  30  in the wavelength range of the light L. Therefore, the light L enters the resin  21  to cure the resin  21 . In addition, the light attenuated after curing the resin  21  is reflected by an interface between the polarizing plate  11 B and the resin  21  (or the resin layer  20 ) to cure the resin  21  again. 
     On the other hand, when the refractive index of the resin  21  before and after curing is set to be lower than the refractive index of the transparent substrate  30  in the wavelength range of the light L, the light L is almost totally reflected by the interface between the transparent substrate  30  and the resin  21 . Therefore, the light L does not enter the resin  21 , and thus the resin  21  is hardly cured. Moreover, when the intermediate layer  40  is not provided and the light shielding layer  50  is provided directly on the front surface  30 A or the back surface  30 C of the transparent substrate  30 , the light L guided through the transparent substrate  30  enters the light shielding layer  50  and is absorbed by the light shielding layer  50 , and therefore the resin  21  is not efficiently cured. 
     As described above, to allow the light L necessary for curing the resin  21  to enter the transparent substrate  30  from the side surface  30 B side thereof, characteristics capable of being cured deeply in the entering direction of the light L are demanded for the resin  21 . To ensure such higher deep-section curability, acyl phosphine oxide-based photopolymerization initiator (for example, see PTLs 5 and 6) or titanocene-based photopolymerization initiator that exhibits at least photobleaching property is used as a photopolymerization initiator, and a light source containing the light L with long wavelength having higher light transmittance to the resin  21 , for example, the light L within the wavelength of around 380 nm to 480 nm is used for photo-curing. Thus, the light transmittance of the resin  21  is increased and the curing of the resin  21  proceeds sequentially toward the deep position as the resin  21  is irradiated with the light. 
     After the transparent substrate  30  is bonded to the display panel  10  with the resin layer  20  in between in this way, the display panel  10  and the transparent substrate  30  thus bonded are placed together with the backlight unit  60  in the exterior member  70 . Consequently, the display  1  illustrated in  FIG. 1  is completed. 
     In the display  1 , when the light enters from the backlight unit  60  to the display panel  10 , the entering light passes through the polarizing plate  11 A, and then passes through the not-illustrated liquid crystal layer while being modulated for each pixel based on a picture voltage applied between the drive substrate  10 A and the counter substrate  10 B. The light that has passed through the liquid crystal layer passes through the counter substrate  10 B having the not-illustrated color filters, thereby being extracted to the outside of the polarizing plate  11 B as color display light. 
     In this case, the resin layer  20  is formed of the resin  21  that has a refractive index higher than the refractive index of the transparent substrate  30  before and after curing in the wavelength range of the light L used for curing. Moreover, the intermediate layer  40  that has a refractive index lower than that of the transparent substrate  30  in the wavelength range of the light L used for curing the resin  21  is provided on the front surface  30 A of the transparent substrate  30 , and the light shielding layer  50  is provided on the front surface  40 A of the intermediate layer  40 . Therefore, the resin  21  on the backside of the light shielding layer  50  is favorably cured close to the display region A in the manufacturing process, and the curing failure of the resin layer  20  on the backside of the light shielding layer  50  is suppressed. Accordingly, leakage of liquid of uncured resin from between the display panel  10  and the transparent substrate  30  is suppressed. 
     Moreover, suppressing the curing failure of the resin layer  20  on the backside of the light shielding layer  50  reduces the possibility of losing the stress balance between the uncured resin  21  remained on the backside of the light shielding layer  50  and the cured resin layer  20 . Therefore, it is possible to suppress occurrence of unevenness caused by variation in a cell gap (the thickness of the liquid crystal layer of the display panel  10 ) in the non-display region B or in the vicinity thereof. Such frame-like unevenness is markedly viewed as display unevenness particularly when a black screen is viewed from an oblique direction or on a low gray level screen, and causes significant lowering of display quality. In the present embodiment, however, occurrence of display unevenness caused by such frame-like unevenness is certainly suppressed. 
     As described above, in the present embodiment, the resin layer  20  is formed of the resin  21  that has a refractive index higher than the refractive index of the transparent substrate  30  before and after curing in the wavelength range of the light L used for curing. In addition, the intermediate layer  40  that has a refractive index lower than that of the transparent substrate  30  in the wavelength range of the light L used for curing the resin  21  is provided on the front surface  30 A of the transparent substrate  30 , and the light shielding layer  50  is provided on the front surface  40 A of the intermediate layer  40 . Therefore, the level relationship between the refractive indices of the resin layer  20 , the transparent substrate  30 , and the intermediate layer  40  is optimally adjusted, and curing failure of the resin layer  20  on the backside of the light shielding layer  50  is suppressed. Consequently, it is possible to suppress leakage of liquid of uncured resin, frame-like display unevenness in the non-display region B or in the vicinity thereof, and the like. 
     Second Embodiment 
       FIG. 8  schematically illustrates a cross-sectional configuration of a display according to a second embodiment of the present invention. The display  1 A is not provided with the intermediate layer  40 , and a light shielding layer  80  is allowed to double with the intermediate layer  40  by adjusting the refractive index of the light shielding layer  80  itself. Except for this point, the display  1 A has a configuration, functions, and effects similar to those of the display  1  according to the first embodiment. Accordingly, the corresponding components will be described with the same reference numerals. 
     The display panel  10 , the resin layer  20 , the transparent substrate  30 , the backlight unit  60 , and the exterior member  70  are configured similarly to those of the first embodiment. 
     The light shielding layer  80  is provided in a region of the front surface  30 A of the transparent substrate  30  facing the non-display region B, and has a refractive index lower than that of the transparent substrate  30  in the wavelength range of the light L used for curing the resin  21 . Therefore, in the display  1 A, it is possible to suppress curing failure of the resin layer  20  on the backside of the light shielding layer  80 , similarly to the first embodiment. 
     Specifically, such a light shielding layer  80  is obtained by mixing or dispersing an opaque material such as carbon black, metal, pigment, and dye into a resin material that has a refractive index lower than that of the transparent substrate  30  in the wavelength range of the light L used for curing the resin  21 . Examples of the resin material serving as a base material include silicone-based coating agent and acrylic coating agent that has a refractive index satisfying the above-described requirement. 
     The display  1 A may be manufactured in the following way, for example. 
       FIG. 9  and  FIG. 10  illustrate a part of a method of manufacturing the display  1 A in process order. First, as illustrated in  FIG. 9A , the display panel  10  is fabricated in a similar way to the first embodiment. On the other hand, as illustrated in  FIG. 9B , the light shielding layer  80  is formed in a region of the front surface  30 A of the transparent substrate  30  facing the non-display region B. For example, application liquid in which an opaque material is mixed or dispersed in the resin material having the refractive index described above is prepared, and the application liquid is applied on the transparent substrate  30 , followed by curing or drying the application liquid to form the light shielding layer  80 . 
     Subsequently, as illustrated in  FIG. 10 , the display panel  10  and the transparent substrate  30  fabricated in the above way are overlaid with the photocurable resin  21  in between, and the light L within the wavelength range curing the resin  21 , for example, ultraviolet light or visible light, is applied from the front surface  30 A side of the transparent substrate  30  as in the first embodiment. Moreover, also as illustrated in  FIG. 10 , the light L is applied from the side surface  30 B side of the transparent substrate  30  at the same time as the light L is applied from the front surface  30 A side of the transparent substrate  30 . Incidentally, the process of applying the light L from the side surface  30 B side of the transparent substrate  30  may be performed at the same time as application from the front surface  30 A side, or may be performed before or after application from the front surface  30 A side. 
       FIG. 11  illustrates a backside of the light shielding layer  80  illustrated in  FIG. 10  in an enlarged manner. As illustrated in  FIG. 11 , the light L applied from the side surface  30 B side enters the transparent substrate  30  from the end surface thereof or from a bonding section of the transparent substrate  30  and the display panel  10 . Since an entering angle is extremely shallow, the light L cures the resin  21  on the backside of the light shielding layer  80  while being guided through the transparent substrate  30 , to form the resin layer  20 . 
     To be more specific, on the front surface  30 A of the transparent substrate  30  (an interface between the transparent substrate  30  and the light shielding layer  80 ), since the refractive index of the light shielding layer  80  is lower than that of the transparent substrate  30  in the wavelength range of the light L used for curing the resin  21 , the light L is totally reflected. On the other hand, on the back surface  30 C of the transparent substrate  30  (an interface between the transparent substrate  30  and the resin  21 ), the refractive index of the resin  21  before and after curing is higher than the refractive index of the transparent substrate  30  in the wavelength range of the light used for curing. Therefore, the light L enters the resin  21  to cure the resin  21 . In addition, the light attenuated after curing the resin  21  is reflected by the interface between the polarizing plate  11 B and the resin  21  (or the resin layer  20 ) to cure the resin  21  again. 
     On the other hand, when the refractive index of the resin  21  before and after curing is set to be lower than the refractive index of the transparent substrate  30  in the wavelength range of the light L, the light L is almost totally reflected by the interface between the transparent substrate  30  and the resin  21 . Therefore, the light L does not enter the resin  21 , and thus the resin  21  is hardly cured. Moreover, when the light shielding layer  80  is provided on the back surface  30 C of the transparent substrate  30 , the light L guided through the transparent substrate  30  enters the light shielding layer  80  and is absorbed by the light shielding layer  80 , and therefore the resin  21  is not efficiently cured. 
     Note that, in the process, to allow the light L necessary for curing the resin  21  to enter from the side surface  30 B side of the transparent substrate  30 , it is desirable that deep-section curability of the resin  21  be ensured as in the first embodiment. 
     After the transparent substrate  30  is bonded to the display panel  10  with the resin layer  20  in between in this way, the display panel  10  and the transparent substrate  30  thus bonded are placed together with the backlight unit  60  in the exterior member  70 . Consequently, the display  1 A illustrated in  FIG. 8  is completed. 
     In the display  1 A, when the light enters from the backlight unit  60  to the display panel  10 , the entering light is modulated for each pixel and is extracted to the outside of the polarizing plate  11 B as color display light, similarly to that of the first embodiment. 
     In this case, the resin layer  20  is formed of the resin  21  that has a refractive index higher than the refractive index of the transparent substrate  30  before and after curing in the wavelength range of the light L used for curing. Moreover, the light shielding layer  80  that has a refractive index lower than that of the transparent substrate  30  in the wavelength range of the light L used for curing the resin  21  is provided on the front surface  30 A of the transparent substrate  30 . Therefore, the resin  21  on the backside of the light shielding layer  80  is favorably cured close to the display region A in the manufacturing process, and curing failure of the resin layer  20  on the backside of the light shielding layer  80  is suppressed. Accordingly, leakage of liquid of uncured resin from between the display panel  10  and the transparent substrate  30  is suppressed. 
     Moreover, suppressing the curing failure of the resin layer  20  on the backside of the light shielding layer  80  reduces the possibility of losing the stress balance between the uncured resin  21  remained on the backside of the light shielding layer  80  and the cured resin layer  20 . Therefore, it is possible to suppress occurrence of unevenness caused by variation in the cell gap (the thickness of the liquid crystal layer of the display panel  10 ) in the non-display region B or in the vicinity thereof. Such frame-like unevenness is markedly viewed as display unevenness particularly when a black screen is viewed from an oblique direction or on a low gray level screen, and causes significant lowering of display quality. In the present embodiment, however, occurrence of display unevenness caused by such frame-like unevenness is certainly suppressed. 
     As described above, in the present embodiment, the resin layer  20  is formed of the resin  21  that has a refractive index higher than the refractive index of the transparent substrate  30  before and after curing in the wavelength range of the light L used for curing. In addition, the light shielding layer  80  that has a refractive index lower than that of the transparent substrate  30  in the wavelength range of the light L used for curing the resin  21  is provided on the front surface  30 A of the transparent substrate  30 . Therefore, the level relationship between the refractive indices of the resin layer  20 , the transparent substrate  30 , and the light shielding layer  80  is optimally adjusted, and the curing failure of the resin layer  20  on the backside of the light shielding layer  80  is suppressed. Consequently, it is possible to suppress leakage of liquid of uncured resin, frame-like display unevenness in the non-display region B or in the vicinity thereof, and the like. 
     Third Embodiment 
       FIG. 12  schematically illustrates a cross-sectional configuration of a display according to a third embodiment of the present invention. The display  1 B is provided with a semi-transmissive layer  90  along the edge b 1  on the inner side of the light shielding layer  50 . Except for this point, the display  1 B has a configuration, functions, and effects similar to those of the display  1  according to the first embodiment. Therefore, the corresponding components will be described with the same reference numerals. 
     The display panel  10 , the resin layer  20 , the transparent substrate  30 , the intermediate layer  40 , the backlight unit  60 , and the exterior member  70  are configured similarly to those of the first embodiment. 
       FIG. 13  illustrates a planar configuration of the display  1 B illustrated in  FIG. 12  as viewed from the light shielding layer  50  side. The non-display region B of the display panel  10  includes a region C where shielding of light from the backlight unit  60  is necessary (a backlight shielding region; a frame-like region outside the boundary a 1  and inside the boundary a 3 ) and a region D where shielding is unnecessary (a backlight non-shielding region; a frame-like region outside the boundary a 3  and inside the edge a 2  of the display panel  10 ). 
     The semi-transmissive layer  90  is provided to have a rectangular frame-like shape in a region between a region of the front surface  40 A of the intermediate layer  40  facing the display region A (the light transmissive section Al) and the light shielding layer  50 . An edge b 3  on the display region A side of the semi-transmissive layer  90  is disposed outside the boundary a 1  (on the non-display region B side). On the other hand, an edge b 4  on the light shielding layer  50  side of the semi-transmissive layer  90  (a boundary between the semi-transmissive layer  90  and the light shielding layer  50 ) is disposed inside the boundary a 3  (on the backlight shielding region C side). In other words, the semi-transmissive layer  90  is provided in the backlight shielding region C. With this arrangement, it is possible to avoid leakage of light from the backlight unit  60  through the semi-transmissive layer  90 . 
     Incidentally, the position of the edge b 4  on the light shielding layer  50  side of the semi-transmissive layer  90  is not particularly limited, and may be disposed outside the boundary a 3  (on the backlight non-shielding region D side). For example, even in the backlight non-shielding region D (outside the boundary a 3 ), the light is allowed to be shielded with use of other shielding member. Therefore, in such a case, the edge b 4  of the semi-transmissive layer  90  may be in the backlight non-shielding region D. Moreover, the edge b 3  of the semi-transmissive layer  90  may overlap with the boundary a 1 . Further, the flat dimension of the semi-transmissive layer  90  may be equal to the flat dimension of the backlight shielding region C (the edge b 3  and the edge b 4  may overlap with the boundary a 1  and the boundary a 3 , respectively). 
       FIG. 14  to  FIG. 17  each illustrate an example of a planar configuration (XY plane configuration) of the semi-transmissive layer  90  on the transparent substrate  30  near the edges b 3  and b 4 . In the light shielding layer  50 , the entire region of the light shielding layer  50  on the transparent substrate  30  is an opaque region Db. In the semi-transmissive layer  90 , selective regions in the semi-transmissive layer  90  on the transparent substrate  30  are the opaque region Db, and the other region is a transparent region Da. The opaque region Db has a thickness of, for example, 0.1 μm to 100 μm, and is formed of an opaque material such as carbon black, metal, pigment, and dye. On the other hand, the transparent region Da is formed of the transparent substrate  30  itself. The semi-transmissive layer  90  exhibits semi-transmissive property by the fact that the opaque region Db and the transparent region Da are mixedly present in the plane, and the light transmittance thereof corresponds to area ratio of the opaque region Db (the opaque region Db/(the transparent region Da+the opaque region Db)). Accordingly, the light transmittance of the semi-transmissive layer  90  is lower than that of the transparent substrate  30 , and is higher than that of the light shielding layer  50 . Note that the light transmittance of the semi-transmissive layer  90  may be uniform (constant) in the semi-transmissive layer  90 , or may be varied in the semi-transmissive layer  90  as follows. 
     To be more specific, as illustrated in  FIG. 14 , in the semi-transmissive layer  90 , for example, a plurality of circle-shaped opaque regions Db (circular regions Db 1 ) are formed in a repeating pattern, and the size of each of the circle is gradually increased from the edge b 3  toward the edge b 4 , namely, from the light transmissive section A 1  side toward the light shielding layer  50  side. In other words, the area ratio of the opaque region Db (the opaque region Db/(the transparent region Da+the opaque region Db)) is gradually increased from the light transmissive section A 1  side toward the light shielding layer  50  side (an area occupied by the opaque region Db is gradually increased). As a result, the light transmittance is gradually decreased from the light transmissive section A 1  side toward the light shielding layer  50  side. 
     Although each of the circular regions Db 1  is desirably small in terms of design, if it is too small, it is difficult to form the opaque region Db. Therefore, in the semi-transmissive layer  90 , the size of the circular region Db 1  (the XY plane dimension) is desirably a diameter of about 0.1 mm to about 2 mm in view of balancing opacity and design. In addition, the size of the plurality of circular regions Db 1  in the semi-transmissive layer  90  is desirably varied in about three to ten levels within such a range. For example, the circular regions Db 1  are arranged at intervals of 1.5 mm in the X direction (in a lateral direction of the paper in  FIG. 14 ), as well as are arranged at intervals of 1.0 mm in the Y direction (in a vertical direction of the paper in  FIG. 14 ) while the diameter is allowed to change to 0.7, 0.8, 0.9, 1.0, 1.1, and 1.2 (mm) in a stepwise fashion from the light transmissive section A 1  side toward the light shielding layer  50  side (from the top to the bottom of the paper in  FIG. 14 ). In addition, the circular regions Db 1  with the same size are arranged in the X direction, and the circular regions Db 1  are arranged (alternately) in the Y direction so that adjacent circular regions Db 1  do not overlap with each other. In this example, the light transmittance is about 70% on the light transmissive section A 1  side and is about 20% on the light shielding layer  50  side. 
     Incidentally, the planar shape (XY plane shape) of the opaque region in the semi-transmissive layer  90  is not limited to the above-described circular shape, and may be a square shape as illustrated in  FIG. 15 . Also in this case, in view of balancing with design described above, the length of one side of the square opaque region (square region Db 2 ) is desirably about 0.1 mm to about 2 mm. In addition, the size of the plurality of square regions Db 2  is desirably varied in about three to ten levels within such a range. For example, the square regions Db 2  are arranged at intervals of 1.5 mm in the X direction (in the lateral direction of the paper in  FIG. 15 ), as well as are arranged at intervals of 1.0 mm in the Y direction (in the vertical direction of the paper in  FIG. 15 ) while one side of the square is allowed to change to 0.5, 0.6, 0.8, and 1.0 (mm) in a stepwise fashion from the light transmissive section A 1  side toward the light shielding layer  50  side (from the top to the bottom of the paper in  FIG. 14 ). In addition, the square regions Db 2  with the same size are arranged in the X direction, and the square regions Db 2  are arranged (alternately) in the Y direction so that adjacent square regions Db 2  do not overlap with each other. In this example, the light transmittance is about 70% on the light transmissive section A 1  side, and is about 20% on the light shielding layer  50  side. 
     Moreover, it is not limited to the circular shape and the square shape described above, and other polygonal shapes such as triangular shape and rectangular shape may be employed. Alternatively, as illustrated in  FIG. 16 , the opaque region Db of the semi-transmissive layer  90  may be formed of a plurality of isosceles triangle opaque regions (triangle regions Db 3 ) arranged in one direction (the entire shape may be a sawtooth shape). For example, the opaque region Db illustrated in  FIG. 16  has a configuration in which the isosceles triangle opaque regions (the triangle regions Db 3 ) having a base width of 1.5 mm and a height of 4 mm are arranged at intervals of 1.5 mm along the X direction (in the lateral direction of the paper in  FIG. 16 ). In this example, the light transmittance is 100% on the light transmissive section A 1  side, and is 0% on the light shielding layer  50  side. With such a configuration, it is possible to gradually decrease the light transmittance from the light transmissive section A 1  side toward the light shielding layer  50  side. 
     Furthermore, the semi-transmissive layer  90  does not necessarily have a regular pattern, and for example, as illustrated in  FIG. 17 , may have a planar configuration in which a plurality of minute opaque regions are discretely arranged so that the light transmittance gradually decreases from the light transmissive section A 1  side toward the light shielding layer  50  side. Note that, in  FIG. 17 , a section illustrated by black color corresponds to the opaque region. 
     In addition, the semi-transmissive layer  90  may be formed of opaque regions having the predetermined shapes arranged irregularly (at random). Moreover, the planar shapes of the opaque regions are not necessarily the same as one another, and may include different shapes from one another. Incidentally, in any case, the area ratio of the opaque region described above is desirably small on the light transmissive section A 1  side and is desirably large on the light shielding layer  50  side. In other words, the light transmittance in a region provided with the semi-transmissive layer  90  is desirably high on the light transmissive section A 1  side and is desirably low on the light shielding layer  50  side. Further, more desirably, the area ratio of the opaque region described above in the semi-transmissive layer  90  is gradually increased, and the light transmittance is gradually decreased from the light transmissive section A 1  side toward the light shielding layer  50  side. This is because stress balance between uncured resin and cured resin can be easily held favorable. 
       FIG. 18  and  FIG. 19  each illustrate a specific configuration example of the transparent substrate  30 , the intermediate layer  40 , the light shielding layer  50 , and the semi-transmissive layer  90 . For example, in  FIG. 18 , the intermediate layer  40  is provided on the entire front surface  30 A of the transparent substrate  30 , and the light shielding layer  50  and the semi-transmissive layer  90  are provided in a region of the front surface  40 A of the intermediate layer  40  facing the non-emission region B. For example, the intermediate layer  40  is formed by coating a transparent resin material that has a refractive index lower than that of the transparent substrate  30  in the wavelength range of the light used for curing the resin configuring the resin layer  20 . The light shielding layer  50  and the opaque region Db of the semi-transmissive layer  90  are formed by, for example, printing or evaporating. 
     In addition, for example in  FIG. 19 , the transparent film  51  is bonded to the entire front surface  30 A (the surface on the light emission side) of the transparent substrate  30  with the intermediate layer  40  serving also as an adhesive layer in between. The light shielding layer  50  and the opaque region Db of the semi-transmissive layer  90  are provided by printing or the like, in a region of the transparent film  51  facing the non-emission region B. The intermediate layer  40  is formed of a transparent adhesive agent that has a refractive index lower than that of the transparent substrate  30  in the wavelength range of the light used for curing the resin configuring the resin layer  20 . 
     The display  1 B may be manufactured in the following way, for example. Incidentally, the processes overlapping with those in the first embodiment will be described with reference to  FIG. 5  to  FIG. 7 . 
     First, similarly to the first embodiment, the display panel  10  is fabricated in the process illustrated in  FIG. 5A . 
     On the other hand, the intermediate layer  40 , the light shielding layer  50 , and the semi-transmissive layer  90  are formed in this order on the front surface  30 A of the transparent substrate  30 . At this time, the intermediate layer  40  is so formed as to have the refractive index smaller than that of the transparent substrate  30  in the wavelength of the light used for curing the resin of the resin layer  20 . 
     To be more specific, for example, as illustrated in  FIG. 18 , the intermediate layer  40  is formed on the entire front surface  30 A of the transparent substrate  30  by coating a transparent resin material that has a refractive index lower than that of the transparent substrate  30  in the wavelength range of the light used for curing the resin configuring the resin layer  20 . After that, for example, the above-described opaque material is dispersed or dissolved in a binder and is then printed, or is directly deposited on the front surface  40 A of the intermediate layer  40 , to provide the light shielding layer  50  and the opaque region Db of the semi-transmissive layer  90 . 
     At this time, in the light shielding layer  50 , the opaque material is solidly evaporated or printed on the transparent substrate  30  to make the entire light shielding layer  50  into an opaque region. 
     On the other hand, on the semi-transmissive layer  90 , the opaque material is evaporated or printed in a selective region on the transparent substrate  30  to make the selective region and the other region in the semi-transmissive layer  90  into an opaque region and a transparent region, respectively. When the semi-transmissive layer  90  is formed by evaporation, it is sufficient for an evaporation mask to use a mask having openings that correspond to the repeating pattern of the opaque region described above. Alternatively, when the semi-transmissive layer  90  is formed by printing, it is sufficient to use a printing plate corresponding to the repeating pattern of the opaque region described above by, for example, screen printing or offset printing. 
     Alternatively, for example, as illustrated in  FIG. 19 , the transparent film  51  on which the light shielding layer  50  and the opaque region Db of the semi-transmissive layer  90  are printed is bonded to the entire front surface  30 A of the transparent substrate  30  with the intermediate layer  40  serving also as an adhesive layer in between. The intermediate layer  40  is formed of a transparent adhesive agent that has a refractive index lower than that of the transparent substrate  30  in the wavelength range of the light used for curing the resin configuring the resin layer  20 . 
     Subsequently, similarly to the first embodiment, the display panel  10  and the transparent substrate  30  are overlaid with the photocurable resin  21  in between in the processes illustrated in  FIG. 6  and  FIG. 7 . After that, the light L within wavelength range curing the resin  21 , for example, ultraviolet light or visible light, is applied from the front surface  30 A side and the side surface  30 B side of the transparent substrate  30  to cure the resin  21 , thereby forming the resin layer  20 . 
     At this time, the semi-transmissive layer  90  is provided in a region between the region of the front surface  40 A of the intermediate layer  40  facing the display region A (the light transmissive section A 1 ) and the light shielding layer  50 , and the light transmittance of the semi-transmissive layer  90  is higher than that of the light shielding layer  50 . Therefore, the semi-transmissive layer  90  is cured by the light L that has been guided through the transparent substrate  30 , and at the same time, is cured by the light L entering from the front surface  30 A side of the transparent substrate  30 . Accordingly, if the width of the non-display region B is large, uncuring of the resin  21  is reduced on the backside of the semi-transmissive layer  90 , and the curing failure of the resin layer  20  on the backside of the light shielding layer  50  and the semi-transmissive layer  90  is suppressed. In addition, drastic change in resin characteristics between the cured section and the uncured section of the resin  21  is suppressed. Therefore, stress balance around the display region A is held favorable, and occurrence of frame-like unevenness due to variation in the cell gap (the thickness of the liquid crystal layer of the display panel  10 ) is suppressed. Moreover, in a region around the display region A, light shielding property of the transparent substrate  30  is not largely impaired. 
     After the transparent substrate  30  is bonded to the display panel  10  with the resin layer  20  in between, the display panel  10  and the transparent substrate  30  thus bonded are placed together with the backlight unit  60  in the exterior member  70 . Consequently, the display  1 B illustrated in  FIG. 12  is completed. 
     In the display  1 B, when the light enters the display panel  10  from the backlight unit  60 , the entering light is modulated for each pixel and is extracted to the outside of the polarizing plate  11 B as color display light, similarly to that of the first embodiment. 
     In this case, the semi-transmissive layer  90  is provided in the region between the region of the front surface  40 A of the intermediate layer  40  facing the display region A (the light transmissive section A 1 ) and the light shielding layer  50 . Therefore, the resin  21  on the backside of the light shielding layer  50  is favorably cured close to the display region A in the manufacturing process, as well as the resin  21  on the backside of the semi-transmissive layer  90  is favorably cured. Thus, the curing failure of the resin layer  20  on the backside of the light shielding layer  50  and the semi-transmissive layer  90  is suppressed. Accordingly, leakage of liquid of uncured resin from between the display panel  10  and the transparent substrate  30  is suppressed even if the width of the non-display region B is large. 
     Moreover, suppressing the curing failure of the resin layer  20  on the backside of the light shielding layer  50  and the semi-transmissive layer  90  reduces the possibility of losing the stress balance between the uncured resin  21  remained on the backside of the light shielding layer  50  and the semi-transmissive layer  90  and the cured resin layer  20 . Therefore, it is possible to suppress occurrence of the frame-like unevenness due to variation in the cell gap (the thickness of the liquid crystal layer of the display panel  10 ) in the non-display region B or in the vicinity thereof to cause the display unevenness. 
     As described above, in the present embodiment, the semi-transmissive layer  90  is provided in the region between the region of the front surface  40 A of the intermediate layer  40  facing the display region A (the light transmissive section A 1 ) and the light shielding layer  50 . Therefore, it is possible to suppress the curing failure of the resin layer  20  on the backside of the light shielding layer  50  and the semiconductor layer  90 . Consequently, possibility of leakage of liquid of uncured resin is allowed to be extremely reduced, and it is advantageous particularly when the width of the non-display region B is large. 
     In addition, it is possible to suppress occurrence of unevenness in thickness of the liquid crystal layer of the display panel  10  and to suppress occurrence of display unevenness around the display region A without large loss of light shielding property around the display region A. Consequently, the display quality is improved, and picture display with high image quality is achievable. 
     (Modification 1) 
     Note that as illustrated in  FIG. 20 , the third embodiment is applicable to a display  1 C provided with the light shielding layer  80  of the second embodiment in place of the intermediate layer  40  and the light shielding layer  50 . Specifically, the semi-transmissive layer  90  may be provided in a region between the region of the front surface  30 A of the transparent substrate  30  facing the display region A (the light transmissive section A 1 ) and the light shielding layer  80 , and the light transmittance of the semi-transmissive layer  90  may be lower than that of the transparent substrate  30  and higher than that of the light shielding layer  80 . In this case, similarly to the light shielding layer  80 , the semi-transmissive layer  90  is set to have the refractive index lower than that of the transparent substrate  30  in the wavelength range of the light L used for curing the resin  21 . 
     EXAMPLES 
     Hereinafter, specific examples of the present invention will be described. 
     Experimental Example 1 
     A display was fabricated in a similar way to the first embodiment. First, the display panels  10  of transmissive VA type having a display size of 46 inches and 55 inches in diagonal dimensions were prepared (see  FIG. 5A ). Each of the display panels  10  was provided with the non-display region B having a width of 11 mm around the display region A (see  FIG. 2 ). 
     Subsequently, the transparent substrate  30  was overlaid on the display panel  10  with the ultraviolet curable resin  21  having the thickness of 100 μm in between (see FIG.  6 ). At this time, five kinds of resins A to E with different refractive indices around a wavelength of 400 nm were used as the resin  21 . The refractive index in a liquid state before curing and the refractive index in a solid state after curing of each of the resins A to E are illustrated in Table 1. A mixture of bis(acyl)phosphine oxide and 1-hydroxycyclohexyl phenyl ketone was used as a polymerization initiator of the resin  21 .

     A glass having a refractive index of 1.52 around a wavelength of 400 nm was used as the transparent substrate  30 . As illustrated in  FIG. 21 , after the intermediate layer  100  was formed on the entire front surface  30 A of the transparent substrate  30 , the light shielding layer  50  was provided in the region of the front surface  40 A of the intermediate layer  40  facing the non-display region B. At this time, coating layers P, Q, and R with the thickness of about 20 μm made of three kinds of resins with different refractive indices were formed as the intermediate layer  40 . The coating layer P was formed using a silicone-based coating agent. The refractive index thereof around the wavelength of 400 nm was 1.46. The coating layer Q was formed using an acryl-based coating agent. The refractive index thereof around the wavelength of 400 nm was 1.48. The coating layer R was formed using a styrene-based coating agent. The refractive index thereof around the wavelength of 400 nm was 1.56. 
     Subsequently, ultraviolet ray was applied from the front surface  30 A side and the side surface  30 B side of the transparent substrate  30  to form the resin layer  20  (see  FIG. 6  and  FIG. 7 ). At this time, a metal halide lamp that has strong emission peak at the wavelength of 365 nm and 405 nm and has illuminance of 100 mW/cm 2  was used as the irradiation light source, and the application time was one minute. 
     Experimental Example 2 
     The display panels  10  similar to those in the experimental example 1 were prepared, and the transparent substrate  30  was overlaid on each of the display panels  10  with the ultraviolet curable resin  21  with the thickness of 100 μm in between. At this time, the resins A to E similar to those in the experimental example 1 were used as the resin  21 . 
     A glass having the refractive index of 1.52 around the wavelength of 400 nm was used as the transparent substrate  30  as in the experimental example 1. As illustrated in  FIG. 22 , the transparent film  51  formed of PET (polyethylene terephthalate) on which the light shielding layer  50  was printed was bonded to the entire front surface  30 A of the transparent substrate  30  with the intermediate layer  40  serving also as an adhesive layer S, T, or U in between. The adhesive layer S was formed using a silicone-based adhesive agent. The refractive index thereof around the wavelength of 400 nm was 1.46. The adhesive layer T was formed using an acryl-based adhesive agent. The refractive index thereof around the wavelength of 400 nm was 1.49. The adhesive layer U was formed using a urethane-based adhesive agent. The refractive index thereof around the wavelength of 400 nm was 1.53. 
     Subsequently, similarly to the experimental example 1, ultraviolet ray was applied from the front surface  30 A side and the side surface  30 B side of the transparent substrate  30 . 
     Comparative Example 1 
     A display panel similar to that in the experimental example 1 was prepared, and a transparent substrate was overlaid on the display panel with ultraviolet curable resin with a thickness of 100 μm in between. At this time, the resin E as in the experimental example 1 was used as the resin. 
     A glass having the refractive index of 1.52 around the wavelength of 400 nm was used as the transparent substrate, as in the experimental example 1. As illustrated in  FIG. 23 , a light shielding layer  150  was provided by printing in a region of a back surface  130 C (on a side bonded to the display panel) of a transparent substrate  130  facing the non-display region B. 
     Subsequently, similarly to the experimental example 1, ultraviolet ray was applied from a front surface  130 A side and a side surface  130 B side of the transparent substrate  130 . 
     (Evaluation Results) 
     Presence or absence of display unevenness was examined for the obtained displays of the experimental examples 1 and 2 and the comparative example 1. The results are illustrated in Table 2 to Table 7. Incidentally, in Table 2 to Table 7, a circle indicates that the display unevenness is not observed, a triangle indicates that frame-like unevenness is slightly observed, and a cross indicates that frame-like unevenness is strong and image quality is deteriorated.

     In addition, the display panel  10  and the transparent substrate  30  bonded were broken away, the resin layer  20  in the section of the display panel  10  corresponding to the display region A and the resin layer  20  in the section (on the backside of the light shielding layer  50 ) corresponding to the non-display region B were obtained, and reaction rate was calculated from carbonyl absorption peak of FTIR spectrum. The results are illustrated in Table 8 to Table 13.

     As is found from Table 2 to Table 5 and Table 8 to Table 11, when the resin D or E that has a refractive index in a liquid state before curing and a refractive index in a solid state after curing both higher than the refractive index of the transparent substrate  30  was used as the resin  21  as well as the coating layer P or Q or the adhesive layer S or T that has a refractive index lower than the refractive index of the transparent substrate  30  was used as the intermediate layer  40 , the resin layer  20  in a section (on the backside of the light shielding layer  50 ) corresponding to the non-display region B was sufficiently cured, and display unevenness was not observed. 
     In contrast, when the resin A, B, or C in which one or both of the refractive index in a liquid state before curing and the refractive index in a solid state after curing is lower than the refractive index of the transparent substrate  30  was used as the resin  21 , the resin layer  20  in the section (on the backside of the light shielding layer  50 ) corresponding to the non-display region B was insufficiently cured, and frame-like unevenness occurred. 
     Moreover, when the coating layer R or the adhesive layer U that has a refractive index higher than that of the transparent substrate  30  was used as the intermediate layer  40 , curing of the resin layer  20  in the section (on the backside of the light shielding layer  50 ) corresponding to the non-display region B was insufficient and frame-like unevenness occurred, irrespective of using any of the resins A to E. 
     In addition, as is found from Table 6, Table 7, Table 12, and Table 13, in the comparative example 1 in which the light shielding layer  150  was provided on the back surface  130 C of the transparent substrate  130 , curing of the resin layer  20  in the section (on the backside of the light shielding layer  150 ) corresponding to the non-display region was insufficient, and frame-like unevenness occurred. 
     Specifically, it was found that forming the resin layer  20  by the resin  21  that has a refractive index in a liquid state before curing and a refractive index in a solid state after curing both higher than the refractive index of the transparent substrate  30  in the wavelength range of the light L used for curing as well as providing the intermediate layer  40  that has a refractive index lower than that of the transparent substrate  30  in the wavelength range of the light L used for curing the resin  21  on the front surface  30 A of the transparent substrate  30  and providing the light shielding layer  50  on the front surface  40 A of the intermediate layer  40  make it possible to suppress the curing failure of the resin layer  20  in the section (on the backside of the light shielding layer  50 ) corresponding to the non-display region B, and to suppress frame-like display unevenness or the like in the non-display region B or in the vicinity thereof. 
     As described above, although the present invention has been described with reference to the embodiments and the examples, the present invention is not limited to the above-described embodiments and the like, and various modifications may be made. For example, in the above-described embodiments and the like, although the case where the polarizing plate  11 B on the light emission side of the display panel  10  is bonded to the surface of the display panel  10  has been described as an example, the polarizing plate  11 B may be provided on the front surface  30 A of the transparent substrate  30 . 
     Moreover, in the above-described embodiments and the above-described examples, although the case where a liquid crystal display panel is used as the display panel  10  has been described as an example, the present invention is applicable to the case where the other display panel  10  such as an organic EL (electroluminescence) panel and a plasma display panel is used.
