Field of the Invention The present invention relates to a technique of displaying an image using a photovoltaic layer such as a light-emitting layer or a liquid crystal layer. [Prior Art] A display body formed by reflecting a reflected light on a back side of a photovoltaic layer to emit light to the observation side, and having light incident on the observation side from the observation side is reflected and emitted to the observation side, The view of the viewing side of the display body is superimposed on the original image (reflecting the background). A technique for suppressing background reflection by using a circularly polarizing plate disposed on the observation side of the photovoltaic layer is disclosed in Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. Hei. . SUMMARY OF THE INVENTION A display body is required to be large screen. However, in order to realize the enlargement of the display body, various problems must be solved: the manufacturing cost is increased or the interest rate is lowered, and the drive circuit is increased in size or power consumption is increased. In view of the above, it is an object of the present invention to increase the area of the display area on the exterior without increasing the size of the display. In order to solve the above problems, a display device according to a first aspect of the present invention includes: a display body in which a light reflection layer that reflects light emitted from a photovoltaic layer is reflected on a viewing side is formed in a display region; a plate-shaped outer casing that displays an edge region of a portion outside the periphery of the body, and a -4-200917223 reflection preventing plate that continuously covers the both sides of the display region and the edge region to suppress incidence from the observation side. The external light reflected by the light reflecting layer or the edge region is emitted toward the observation side. In the above configuration, the 'reflection prevention plate' is continuous across the display area and the edge area, and thus the boundary between the display body and the exterior body is not conspicuous. Therefore, the area of the display area on the appearance can be enlarged without increasing the size of the display body. The display device relating to the present invention is utilized in various electronic devices. In a specific example of the display device according to the first type, the optical characteristics of the edge region of the exterior body and the optical characteristics of the display region of the display body (when the full pixel is not lit) are substantially identical ( Slightly consistent). More specifically, the reflectance (%) when the edge portion of the outer casing is irradiated with the measurement light by the reflection preventing plate is at the same wavelength as the reflectance (%) when the measurement light is applied to the display region of the display body by the reflection preventing plate. The maximum 値 of the difference 値 (for example, the difference 値 Δ in FIG. 4 ) is 3% or less when the wavelength of the measurement light is in the range of 5 〇 Onm to 600 nm. According to this aspect, the boundary between the display body and the exterior body can be made not particularly conspicuous. In a specific example of the display device of the first type, the exterior system has a frame-like member in which the opening portion is formed such that the display region of the display body is located inside the inner peripheral edge. Further, the display system includes a light shielding layer that shields the gaps of the respective pixels, and the outer periphery of the light shielding layer is located outside the inner periphery of the exterior body. According to this aspect, since the outer periphery of the light shielding layer is located outside the inner periphery of the outer casing, a gap is formed between the inner periphery of the outer casing and the outer periphery of the light shielding layer (for example, the area GB of FIG. 5). 'The former can make the boundary between the display body and the exterior body less visible. -5- 200917223 In a specific example of the display device of the first type, the exterior system is bonded to the surface of the observation side of the display body, and the reflection preventing plate is bonded to the surface of the observation side of the exterior body. In this type, since the reflection preventing plate is separated from the surface on the observation side of the display body, the transfer of heat from the display body to the reflection preventing plate can be suppressed. Thereby, deterioration of the reflection preventing plate due to heating can be suppressed. However, the reflection preventing plate is separated from the surface on the observation side of the display body, and light is reflected on the surface on the observation side of the display body or the surface on the back side of the reflection preventing plate. Therefore, the display device according to a specific example suitable for the first type includes an anti-reflection on at least one of the opposing surface of the anti-reflection plate and the display body and the opposite surface of the display body and the anti-reflection plate. Reflection (AR; Anti Reflection) coating. Further, the display device of another type includes a light-transmissive material which is filled in a space which is interposed between the surface of the observation side of the display body and the reflection preventing plate. According to each of the above types, it is advantageous in that the reflection of the surface on the observation side of the display body or the surface on the back side of the reflection preventing plate can be suppressed. In a specific example of the display device of the first type, the exterior system is placed on the plate-like member on the back side of the display body. According to this aspect, it is advantageous in that the joining of the exterior body and the display body can be facilitated, and the mechanical strength of the display body can be reinforced by the exterior body. In another specific example of the first type, a light-shielding property adjustment layer including a portion located on the outer side of the display region is formed on the opposite surface of the reflection preventing plate from the display body (for example, FIG. 13 or FIG. Feature adjustment layer 8 0 ). According to the above aspect, even if the optical characteristics of the edge region of the exterior body do not coincide with the optical characteristics of the display region of the display body, the display region of the property adjustment layer and the display body is made by -6-200917223. The optical characteristics match, and the periphery of the display body (the boundary between the display area and the characteristic adjustment layer) can be made inconspicuous. Further, in a specific form, the property adjustment layer includes a first layer formed on the back side surface of the anti-reflection sheet and a second layer formed on the surface of the first layer, and a plurality of openings formed in the second layer . According to the above pattern, the optical characteristics of the property adjustment layer can be adjusted by appropriately selecting the type or distribution (total or dense) of each opening of the second layer. Further, when one of the first layer and the second layer is formed with a film thickness which is extremely thin to the extent that the emitted light from the display body is sufficiently transmitted, both the outer side and the inner side of the display region in the anti-reflection plate are used ( The entire area of the anti-reflection plate and the opposite surface of the display body is formed to form the layer. A display device according to a second aspect of the present invention includes: a plurality of display bodies in which light-reflecting layers that reflect light emitted from the photovoltaic layer are reflected on the observation side are formed in the respective display regions, and are included in each display body The plate-shaped outer casing of the edge region of the outer side of the periphery (for example, the portion A2a of FIG. 8 or the portion A2b of FIG. 9) and the reflection preventing plate are continuously covered by the display region and the edge region of the plurality of display bodies. The plates of the two are used to suppress the emission of external light reflected by the light reflecting layer or the edge region of each display body from the observation side toward the observation side. In the above configuration, the reflection preventing plate is continuous across the plurality of display regions and the edge regions, and thus the boundary between the respective display bodies and the exterior body is not conspicuous. Therefore, it is possible to enlarge the area of the display area on the appearance without increasing the size of each display body. The display device of the second type is used in various electronic devices. In a specific example of the display device of the second type, a plurality of display bodies 200917223 are arranged apart from each other, and the exterior system includes a portion located in a gap between adjacent display bodies (for example, part A2b of FIG. 9) . According to the above aspect, it is possible to make the boundaries between the adjacent display bodies and the externally mounted bodies inconspicuous, and to enlarge the area of the display area in appearance by separating the display bodies from each other. In a specific example of the display device according to the second type, the reflectance (%) when the reflection preventing plate is irradiated with the measurement light in the edge region of the outer casing, and the measurement light is applied to the display region of each display body by the reflection preventing plate. The maximum 値 of the difference 値 (for example, the difference 値Δ in FIG. 4 ) at the same wavelength is 3% or less in the range of 500 nm or more and 600 nm or less of the wavelength of the measurement light. According to this form, the boundary between each display body and the exterior body can be made not particularly conspicuous. In a specific example of the display device of the second type, the exterior system forms a plurality of plate members having a plurality of openings so that the display region of each display body is located inside the inner periphery. In addition, the display body is provided with a light shielding layer which is formed such that the outer peripheral edge is located on the outer side of the inner periphery of the outer casing and shields the gap between the pixels. According to this aspect, since the outer periphery of the light shielding layer is located outside the inner periphery of the outer casing, a gap is formed between the inner periphery of the outer casing and the outer periphery of the light shielding layer (for example, the area GB of FIG. 5). The former can make the boundary between each display body and the outer body less conspicuous. In a specific example of the display device of the second type, the exterior system is bonded to the surface of each of the plurality of display bodies, and the reflection preventing plate is bonded to the surface of the observation side of the exterior body. In this type, since the reflection preventing plate is separated by the surface on the observation side of each display body, heat can be suppressed from being transmitted from the display body to the reflection preventing plate of -8-200917223. Thereby, deterioration of the reflection preventing plate due to heating can be suppressed. However, the reflection preventing plate is separated from the surface on the observation side of the display body, and light is reflected on the surface of the observation side of each display body or the surface on the back side of the reflection preventing plate. Therefore, the display device according to a specific example suitable for the second type is provided on at least one of the opposing surface of the antireflection plate and each of the display bodies, and the opposing surface of each of the display bodies and the antireflection plate. An anti-reflective (AR) coating is formed. Further, the display device of another type has a light-transmissive filling material which is filled in a space between the surface of the observation side of each display body and the gap between the reflection preventing plates. According to the above various types, the advantage is that the reflection of the surface of the observation side of each display body or the surface of the back side of the reflection preventing plate can be suppressed. In a specific example of the display device of the second type, the exterior system is disposed on the plate-like member on the back side of the plurality of display bodies. According to this aspect, it is advantageous in that the joining of the exterior body and the plurality of display bodies can be facilitated, and the mechanical strength of each of the display bodies can be reinforced by the exterior body. [Embodiment] Hereinafter, a plurality of embodiments of the present invention will be described with reference to the drawings. Further, in the following description, the respective elements of the same reference numerals are attached, and in particular, the functions or functions are common except for the case where they are not mentioned. <A: First Embodiment> Fig. 1 is an exploded perspective view showing a configuration of a display device 100A according to a first embodiment of the present invention. Figure 2 is a cross-sectional view of the device 〇〇 △ 200917223. The display device 100A shown in Fig. 1 and Fig. 2 is a planar structure in which the display body D, the exterior body 40, and the reflection preventing plate 60 are laminated. The display body D displays various images by a plurality of pixels p arranged in a plane in the display area A 1 . As shown in Fig. 2, the display body D includes a first substrate 10 and a second substrate 20 which are bonded by a light-transmitting adhesive layer 25. The second substrate 20 is located on the observation side of the first substrate 1 (that is, the viewer side of the display image can be visually confirmed by the display D). The plurality of reflective light layers 11 of the respective faces P of the first substrate 10 and the opposite faces of the second substrate 20 are formed apart from each other. Each of the light reflecting layers 11 is a film body formed of a light reflective material. Further, the light reflection layer 11 is also continuously formed across the entire area of the display area A1. On the surface of the first substrate 10, a light-transmitting insulating layer 12 covering each of the light-reflecting layers 11 is formed. On the surface of the insulating layer 12, a plurality of first electrodes 14 corresponding to the respective pixels p are formed to be spaced apart from each other. Each of the first electrodes 14 is an electrode formed of a light-transmitting conductive material of ITO (Indium Tin Oxide). As shown in Fig. 2, the light-reflecting layer 11 and the first electrode 14 are overlapped in the vertical direction of the first substrate 1A. On the surface of the insulating layer 12, a partition layer (bank) 13 is formed. The partition layer 13 is an insulating layer that partitions the space on the surface of the first substrate 1 into a shape (lattice shape) per pixel P. The light-emitting layer 15 is formed of an organic EL (electroluminescence) material in a space surrounded by the inner surface of the partition layer 13 and having the first electrode 14 as a bottom surface. The partition layer 13 and the light-emitting layer 15 are covered by the second electrode 16. The second electrode 16 is a translucent conductive film in which a plurality of pixels P are continuous across the -10-200917223. The light-emitting layer 15 emits white light in accordance with the amount of light of electric energy supplied from the first electrode 14 (anode) and the second electrode 16 (cathode). The light emitted from the light-emitting layer 15 toward the observation side and the reflected light emitted from the light reflection layer 11 are transmitted through the second electrode 16 to the observation side to display various images. Each element on the first substrate 1 is sealed by a light-transmissive sealing body 17. The second substrate 20 is a light-transmissive plate material in which the light shielding layer 21 and the plurality of color layers 22 (22R, 22G, and 22B) are formed on the surface opposite to the first substrate 10. The light-shielding layer 2 1 is formed in a lattice-like region (a region superposed on the first electrode 14 or the light-reflecting layer 11) corresponding to each pixel P to block the gap between the pixels P. Fig. 3 is a view showing the relationship of the planes of the respective elements of the display device 100A. However, FIG. 3 is an illustration in which the reflection preventing plate 60 is omitted. As shown in Fig. 2 and Fig. 3, the outer shape of the light shielding layer 21 is larger than that of the display area A1, and the former is large. Therefore, the outer peripheral edge Q1 of the light shielding layer 2 1 is located outside the display area A 1 . Each of the colored layers 22 of FIG. 2 is a light-transmissive film body colored in any of a plurality of colors (red (22R), green (22G), and blue (22B)), which is formed on the light shielding layer 21. The inside of each opening. Therefore, the plurality of color layers 22 are arranged in a plane in the display area A1. The emitted light from the light-emitting layer 15 passes through the colored layers 22 and is emitted toward the observation side to make the color image visible to the observer.

例如壓克力樹脂或聚碳酸酯）的基板作爲支撐體62。如 圖2所示，圚偏光板64係由被黏貼在支撐體62的觀察側 的表面之位相差板64 1、與被黏貼在位相差板64 1的表面 之偏光板642所構成。從而，在即使外光由觀察側射入顯 示裝置10 0 Α而在光反射層11的表面或外裝體40的邊緣 區域A2反射之場合，也可抑制該反射光往觀察側的射出 〇 圖4係圖示在將指定的光點（spot )徑的可見光（以

圖4之特性C 3 ’係在設置反射防止板6 0之本型態的 構成基礎下，中介著反射防止板6 0將測定光照射到外裝 體4〇之邊緣區域A2之場合之測定結果。從特性2與特 性C 3之對比可以理解，本型態中，被選定以外裝體4 〇的 邊緣區域A2之光反射特性、與顯示體D的顯示區域a i 內之光反射特性實質上一致化（大略一致）作爲外裝體 40之邊緣區域A2或顯示體D之各要素之光學的特性。進 一步詳述，對各個外裝體40之邊緣區域A2與顯示體D 之顯不區域A 1個別地照射測定光以測定反射光，在算定 針對各區域以相同波長照射時被測定之反射率之差分値A 時’被選定500nm以上600nm以下之波長範圍r內之差 分値△的最大値在3 %以下（在1 %以下更好），成爲外裝 體40之邊緣區域A2或顯示體D之各要素之光學的特性 (更詳細說明於材料或加工法）。例如，藉由將針對顯示 體D之顯示區域A

止板60僅重疊在顯示區域A1之構成相比較’可以使外 裝體40與顯示體D之邊界較不醒目。特別是’本型態中 ，因爲是選定於邊緣區域A2與顯示區域A1使光反射特 性（反射率）實質上一致化（大略一致）作爲外裝體40 或顯示體D之特性’所以以上的效果格外顯著。接著’ 藉由將外裝體40與顯示體D之邊界作成不鮮明，利用者 就能覺察顯示裝置1 0 0 A之顯示區域是否剛好連續到外裝 體40之外周緣R1之附近（反射防止板60之全區域）。 亦即，本型態中，可以在不大型化顯示體100A下擴大外 觀上的顯示區域的面積。 又，由於在使顯示區域A1之全體發光之場合顯示區 域1與非發光之邊緣區域A2之邊界可以被利用者覺察， 因而所謂外觀上之顯示區域之面積被放大之效果’係對於 顯示發光層15在熄燈時以灰階之黑色爲背景而在顯示區 域A 1之中央部配置被寫體之影像（亦即顯示區域A1之

緣R2之間之區域GB照射測定光測定反射率之結果。 在第1基板10之中區域GB內之區域’因爲在顯示 區域A1內被形成用以供給驅動訊號或電源電位之配線（ 圖示略），所以區域GB之特性C4’如圖4所示’係不 同於外裝體40之邊緣區域A2之特性C3或顯示區域A1 內之特性C2。從而，在圖5之構成’如相較於反射防止 板6 0被排除之構成（特性C 1 )’是外裝體4 0與顯示體 D之邊界較不醒目之效果確實奏效’但如相較於圖2之構 成，邊界被覺察之可能性則比較局。亦即，在圖2之構成 ，因爲遮光層21之外周緣Q1是位於外裝體40之內周緣 R2之外側’所以’相較於圖5之構成’耶者的優點在方·^ 外裝體40與顯示體D之邊界較不醒目。 <B:第2實施形態> 圖ό係顯示有關本發明的第2實施型態'之顯不裝置 -16- 200917223

(第2基板20)之觀察側之表面形成抗反 射塗層7 0 C。 第1實施型態之構成因爲反射防止板60之背面側之 表面或顯示體D之觀察側之表面是與空氣接觸，所以容 易在該表面反射來自發光層15之射出光。對此，本型態 因爲係利用抗反射塗層70 ( 70B、70C )抑制反射防止板 60之背面側之表面或顯示體D之觀察側之表面之反射， 而可以提高來自發光層1 5之射出光之利用效率。此外，

40 is an opaque frame-shaped plate material which is formed into a rectangular opening portion 42. The exterior body 40 is attached to the surface of the observation side of the display body D -11 - 200917223 (that is, the surface on the observation side of the second substrate 20). For example, it is suitable to use an aluminum plate coated with black as the exterior body 40. As shown in FIG. 2 and FIG. 3, the outer dimensions of the outer casing 40 (dimensions of the outer edges R1) and the outer dimensions of the display body D (dimensions of the first substrate or the second substrate 20) are larger. . The exterior body 40 displays the body D, and the outer peripheral edge R13 of the exterior body 40 is fixed to the outside of the periphery Q2 of the display body D (1 substrate 10 or the second substrate 20), that is, the observation side of the exterior body 40 The surface (hereinafter referred to as "edge region") A2 includes a portion on the outer side of the peripheral edge Q2 of the display body D. Further, the display region A1 is located inside the opening portion 4 2 (the inner edge R2 of the outer casing 40), and the light shielding layer The outer peripheral edge Q1 of 21 is located outside the opening portion (the inner peripheral edge R2 of the outer casing 40). As shown in FIG. 1 and FIG. 2, the anti-reflection plate 60 is a plate which is formed into a shape (size and shape) in which the outer periphery R 1 of the outer casing 40 is matched, and is the same as the display D. The substrate 10 or the second substrate 2 has a large area of the reflection preventing plate 60. As shown in Fig. 2, the reflection preventing plate 60 is joined to the edge region A2 such that the periphery of the reflection preventing plate 60 is aligned with the outer edge R1 of the outer casing 40. Therefore, the reflection preventing plate 60 is continuous with the edge area A2 across the display area A1 so as to cover both the display D exposed in the opening 42 of the exterior body 40 and the exterior body 40. As shown in FIG. 2, between the surface on the back side of the anti-reflection plate 60 and the surface on the observation side of the display body D (second substrate 20), the area inside the mouth portion 42 corresponds to the outer casing 40. And the space v of the interval between the circumference 10 and the circumference of the circumference of the circumference of the circumference of the circumference of the circumference of the circumference of the circumference of the circumference of Since the reflection preventing plate 60 and the display body D are spaced apart from each other in the space V as described above, the heat generated in the display body D is less likely to be transmitted to the reflection than the configuration in which the reflection preventing plate 6 is closely attached to the display body D. Prevent plate 60. Therefore, there is an advantage that the deterioration of the reflection preventing plate 60 (especially the circular polarizing plate 64) can be suppressed by heating. As shown in FIGS. 1 and 2, the reflection preventing plate 60 is composed of a support 62 and a circularly polarizing plate 64. The support body 62 is a light-transmitting plate which reinforces the mechanical strength of the circular polarizing plate 64. It is preferable to use a substrate made of glass or resin (for example, acrylic resin or polycarbonate) as the support 62. As shown in Fig. 2, the iridium polarizing plate 64 is composed of a phase difference plate 64 1 adhered to the surface on the observation side of the support 62 and a polarizing plate 642 adhered to the surface of the phase difference plate 64 1 . Therefore, even when external light is incident on the display device 100 from the observation side and is reflected on the surface of the light reflection layer 11 or the edge region A2 of the exterior body 40, the emission of the reflected light toward the observation side can be suppressed. 4 is a graph showing the characteristics of reflected light emitted from the observation side when visible light (hereinafter referred to as "measurement light") of a predetermined spot diameter is irradiated to the respective portions of the display device 1A by the observation side. The horizontal axis of Fig. 4 measures the wavelength (nm) of light, and the vertical axis represents the reflectance (i.e., the ratio (%) of the amount of light of the reflected light to the amount of light of the measured light). The characteristic C1 of Fig. 4 is a measurement result in the case where the light-emitting layer 15 of the full-pixel P is completely extinguished, and the measurement light is incident on the display area A1, in the configuration in which the reflection preventing plate 60 is removed. On the other hand, the characteristic C2 is a configuration in which the reflection mode of the reflection preventing plate 60 is set, and the light-emitting layer 15 of the full-pixel p-13-200917223 is completely extinguished, and the reflection preventing plate 60 is interposed to illuminate the measurement light. The measurement result in the case where the area A 1 is displayed. It can be understood from the comparison between the characteristic C1 and the characteristic C2 that the amount of light reflected from the incident light from the observation side of the display device i 〇〇A to the display body D (particularly, the light reflection layer 1 1 ) is emitted toward the observation side. It is sufficiently suppressed by the reflection preventing plate 60. Thereby, the reflection of the background can be suppressed. The characteristic C 3 ' of FIG. 4 is based on the configuration in which the reflection preventing plate 60 is provided, and the measurement result in the case where the reflection preventing plate 60 is irradiated with the measurement light to the edge region A2 of the outer casing 4 is interposed. . It can be understood from the comparison between the characteristic 2 and the characteristic C 3 that in the present mode, the light reflection characteristic of the edge region A2 of the selected exterior body 4 实质上 substantially coincides with the light reflection characteristic in the display region ai of the display body D. (Significantly identical) is an optical characteristic of each of the edge region A2 of the exterior body 40 or the display body D. More specifically, the edge area A2 of each of the exterior bodies 40 and the display area A1 of the display body D are individually irradiated with measurement light to measure the reflected light, and the reflectance measured when the respective areas are irradiated at the same wavelength is calculated. When the difference 値A is selected, the maximum 値 of the difference 値Δ in the wavelength range r of 500 nm or more and 600 nm or less is 3% or less (more preferably 1% or less), and becomes the edge region A2 of the exterior body 40 or the display body D. The optical properties of each element (more details on materials or processing methods). For example, the exterior body 40 is formed by applying a coating material to the surface (edge region A2) of the sheet material in the display region A1 of the display body D in which the reflectance measured beforehand is satisfied. As described above, the reflection preventing plate 60 of the continuous type (size and shape) across the display area A 1 and the edge area A2 -14 - 200917223 is disposed to cover both the exterior body 40 and the display body D. . Therefore, it is possible to suppress not only the reflection of the background but also the configuration in which the reflection preventing plate 60 is not provided or the reflection preventing plate 60 is overlapped only in the configuration of the display area A1, so that the boundary between the exterior body 40 and the display body D can be made less conspicuous. . In particular, in the present mode, the light reflection characteristics (reflectance) are substantially equalized (substantially identical) in the edge region A2 and the display region A1 as the characteristics of the exterior body 40 or the display body D. The effect is particularly remarkable. Then, by making the boundary between the exterior body 40 and the display body D unclear, the user can perceive whether the display area of the display device 100A is just continuous to the periphery of the outer periphery R1 of the exterior body 40 (reflection prevention plate) 60 full area). That is, in this type, the area of the display area on the exterior can be enlarged without increasing the size of the display body 100A. Further, since the boundary between the display region 1 and the non-light-emitting edge region A2 can be perceived by the user when the entire display region A1 is caused to emit light, the effect of the area of the display region on the appearance is enlarged. When the light is turned off, the image of the object to be written is placed in the center of the display area A 1 with the gray of the gray level as the background (that is, the optical characteristic and the edge area are formed in the display area A1 for the non-light-emitting area other than the object to be written. The case of A2 is the most effective. In the above description, the measurement result in the case where the measurement light is irradiated into the display area A 1 is exemplified as the characteristic C2, and the area outside the display area A 1 toward the inside of the opening 42 of the exterior body 40 ( In the case where the light-shielding layer 21 is present, the measurement result of the GA irradiation measurement light is slightly equivalent to the characteristic C2 of -15-200917223. Therefore, the optical characteristics of the outer casing 40 or the display body can be selected such that the light reflection characteristics of the region ga and the light reflection characteristics of the edge region A2 of the outer casing 40 are substantially identical (slightly coincident). Although the peripheral edge Q1 of the light shielding layer 21 of FIG. 2 is located outside the opening portion 4 2 of the exterior body 40, as shown in FIG. 5, the outer peripheral edge Q1 of the light shielding layer 21 is located at the opening of the exterior body 40. The composition of the inner side of 42 (inner circumference R2) can also be employed. The characteristic C4 of Fig. 4 is a result of measuring the reflectance of the measurement light in the region GB between the outer peripheral edge Q1 of the light shielding layer 21 and the inner peripheral edge R2 of the outer casing 40 in the configuration of Fig. 5 . In the region "in the region GB of the first substrate 10", since the wiring for supplying the driving signal or the power supply potential (not shown) is formed in the display region A1, the characteristic C4' of the region GB is as shown in FIG. It is different from the characteristic C3 of the edge area A2 of the outer casing 40 or the characteristic C2 of the display area A1. Therefore, in the configuration of Fig. 5, the configuration (the characteristic C 1 ) that is excluded from the reflection preventing plate 60 is that the boundary between the exterior body 40 and the display body D is less conspicuous, but the effect is true. Compared with the composition of Figure 2, the possibility of the boundary being perceived is relatively inconsistency. That is, in the configuration of Fig. 2, since the outer peripheral edge Q1 of the light shielding layer 21 is located outside the inner periphery R2 of the outer casing 40, the advantage of the composition of the outer layer of the outer casing 40 is better than that of the composition of Fig. 5. The boundary between the body 40 and the display body D is less conspicuous. <B: Second Embodiment> Fig. 分解 is an exploded perspective view showing a configuration of a display device of the second embodiment of the present invention -16-200917223 100B. As shown in Fig. 6, the display device 100B has a planar structure in which the display body DA and the display DB upper laminated body 4 and the reflection preventing plate 60 are disposed apart from each other in the same plane. Each of the display body DA and the display body DB has the same configuration as that of the first embodiment display body D, and various types of pixels are displayed by a plurality of pixels p that are planarly arranged in the display area A1. In the following description, when the display body DA and the display body DB are not particularly distinguished, the two are collectively referred to as "display body D". Fig. 7 is a view showing the relationship of the planes of the respective elements of the display device 100B. However, FIG. 7 omits illustration of the reflection preventing plate 60. In addition, 8, the cross-sectional view seen from the Vllla-VIIIa line or the Vlllb-Vlllb line of Fig. 7 (that is, the cross-sectional view of the vicinity of the periphery of the outer casing 40), the plan is seen from the IX-IX line of Fig. 7. The cross-sectional view (that is, the cross-sectional view of the vicinity of the gap between the display body DA and the display body DB). As shown in Figs. 7 and 8, the outer shape of the light shielding layer 21 is larger than that of the display area A1. Therefore, the outer peripheral edge Q1 of the light shielding layer 21 is located outside the display area A1. As shown in Fig. 6 and Fig. 7, the exterior body 40 is an opaque plate material which is formed in a rectangular opening portion corresponding to two of the display body DA and the display body DB. The outer casing 4 is joined to the side of the observation side of the display body D (i.e., the surface on the observation side of the second substrate 20) by the double-sided tape 30. As shown in Fig. 7 and Fig. 8, the outer casing 4〇 and the outer peripheral edge R1 of each of the display body D outer casings 40 are located outside the peripheral edge Q2 of each display body D, and must be shown in Fig. 9 and The more obvious 4 2 table is fixed in the way of side-17-200917223. Therefore, as shown in Fig. 8, the edge region A2 of the surface on the observation side of the exterior body 40 includes a portion A2a located outside the periphery Q2 of each display body D. In addition, since the display body DA and the display body DB are spaced apart from each other, the edge region A2 includes a portion A 2 b ° located in the gap between the display body DA and the display body DB as shown in FIG. As shown in FIGS. 7 to 9, the display area A1 of each display body D is located inside the opening portion 42 (the inner circumference R2 of the exterior body 40) corresponding to the display body D, and the light shielding layer of each display body D The outer peripheral edge Q1 of 21 is located on the outer side of the opening portion 42 (the inner peripheral edge R2 of the outer casing 40) corresponding to the display body D. As shown in Fig. 6 and Fig. 8, the 'reflection preventing plate 60' is a rectangular plate which is formed into a shape (size and shape) which coincides with the outer peripheral edge R1 of the outer casing 40, compared with the display body. The DA and the total area of the display body DB have a large area of the reflection preventing plate 60. Similarly to the first embodiment, the reflection preventing plate 60 is composed of a support 62 and a circularly polarizing plate 64. The reflection preventing plate 60 is joined to the edge region A2 such that the periphery of the reflection preventing plate 60 coincides with the outer peripheral edge R1 of the outer casing 40. Therefore, the reflection preventing plate 60' is continuous with the display area A1 and the edge area A2 so as to cover the display body DA exposed from the respective opening portions 42 of the exterior body 40 and the display body DB and the exterior body 40. As shown in Figs. 8 and 9, the space V is formed between the surface on the back side of the reflection preventing plate 60 and the surface on the observation side of each of the display bodies D. Therefore, the heat generated in the display body D as compared with the configuration in which the reflection preventing plate 60 and the display body D are closely adhered to each other is less likely to be transmitted to the reflection preventing plate 60. That is, it has the advantage of being able to suppress the deterioration of the circular polarizing plate 64 by heating -18-200917223. As described with reference to Fig. 4, in the present mode, the light reflection characteristics of the edge region A 2 of the selected exterior body 40 and the light reflection characteristics in the display region A 1 of each display d are substantially identical. The optical characteristics of the edge regions A2 of the package 4 or the elements of the display body D. More specifically, the edge area A2 of each exterior body 40 and the display area A1 of the display body D are individually irradiated with measurement light to measure reflected light, and the difference in reflectance measured when irradiating the same wavelength for each area is calculated. In the case of 値Δ, the maximum 値 of the difference 値Δ in the wavelength range R selected from 500 nm to 600 nm is 3% or less (more preferably 1% or less), and becomes the edge region A2 of the exterior body 40 or the display body D. The optical properties of each element (more details on materials or processing methods). As described above, the reflection preventing plate 60 of the pattern (size and shape) which is continuous across the display area A1 and the edge area A2 is provided so as to cover both the exterior body 40 and the display body D. Therefore, not only the reflection of the background can be suppressed, but also the configuration of the reflection preventing plate 60 is not provided or the reflection preventing plate 60 is superposed only on the display area A1 of each display body D, and the exterior body 40 (part A2a and The boundary between the portion A2b) and the display body D is less conspicuous. In particular, in the present embodiment, since the light reflection characteristics (reflectance) are selected to be slightly matched between the edge region A2 and the display region A1 as the characteristics of the exterior body 40 or the respective display bodies D, the above effects are particularly remarkable. . Then, by making the boundary between the exterior body 40 and the display body D unclear, the observer can perceive whether the display area of the display device 1B is just continuous to the periphery of the outer periphery R1 of the exterior body 40 (reflection - 19- 200917223 Prevent the entire area of the board 60). That is, in this type, the area of the display area in appearance can be enlarged without enlarging the display body 100. <C: Third embodiment> Next, a third embodiment of the present invention will be described. In addition, the configuration based on the first embodiment is exemplified below. However, from the third embodiment to the sixth embodiment, the second embodiment having a plurality of display bodies d (DA, DB) is used. The display device 100B is also applicable similarly. Fig. 10 is a cross-sectional view showing the configuration of a display device 100C according to a third embodiment of the present invention. As shown in FIG. 1A, an anti-reflection coating 70 (70A, 70B) for suppressing reflection of the surface is formed in contact with the surface of the air among the light-transmitting elements of the display device i〇〇c. 70C). More specifically, an anti-reflection coating 70 A is formed on the surface of the observation side of the reflection preventing plate 60 (circular polarizing plate 64), and an anti-reflection coating is formed on the surface of the back side of the reflection preventing plate 60 (support 62). 70B. Further, an anti-reflection coating layer 70C is formed on the surface of the observation side of the display body D (second substrate 20). In the first embodiment, since the surface on the back side of the anti-reflection sheet 60 or the surface on the observation side of the display body D is in contact with air, it is easy to reflect the light emitted from the light-emitting layer 15 on the surface. In this case, since the anti-reflection coating 70 (70B, 70C) suppresses the reflection of the surface of the back side of the reflection preventing plate 60 or the surface of the observation side of the display body D, the light-emitting layer 15 can be improved. The efficiency of the use of light. Further, since the anti-reflection coating -20-200917223 7〇A' is also formed on the surface of the observation side of the reflection preventing plate 60, there is an advantage that the background can be effectively prevented from being reflected by the surface. <D: Fourth Embodiment> Fig. 1 is a cross-sectional view showing a configuration of a display of the fourth embodiment of the present invention. As shown in Fig. 11, the surface of the back surface side of the anti-reflection plate support 62) and the display body D (the surface on the observation side of the second substrate and the inner peripheral surface of the opening portion 4 of the exterior body 40) are The space V is sealed with a light-transmissive crucible 75. The crucible 75 can be formed of a resin material, and the refractive index of the crucible 75 is equal to the refractive index of at least one of the second substrate 20 of the support 62. In the case of the presence of air in the space V, the former can suppress the surface of the side of the reflection preventing plate 60 or the observation of the display body D by reducing the difference between the inside of the space V and the refractive index of the support 62 or the second 20 The light reflection on the surface of the side. Even in the third embodiment, the anti-reflection (AR) coating 70B 70C is omitted, and the interest rate of the light emitted from the light-emitting layer 15 can be increased. However, the composition of Fig. 11 can also be used. The anti-reflection coatings 70B and 70C of Fig. 1 are provided. <E: Fifth Embodiment> Fig. 12 is a cross-sectional view showing a display device 100E according to the fifth embodiment. As shown in Fig. 12, the outer casing 40 of this type is a plate-shaped member on the back side of the display body D. The exterior body 40 does not reflect

The surface on the back side of the display body D (the first substrate 10) is bonded to the exterior body 40. The surface on the observation side of the exterior body 40 on the outer side of the periphery Q2 of the display body D is the edge area A2. The light shielding layer 21 of the display body D is formed across the entire area of the second substrate 20. The plate 60' is provided so as to be continuous with the display area A1 across the edge area A2 and to cover the exterior body 40 and the display body D. Further, as in the first embodiment, light reflection is performed on the edge area A2 of the exterior body 40. The characteristics are slightly matched with the light reflection characteristics in the display area A 1 of the display body D, and are selected as the optical characteristics of the edge regions A2 of the exterior body 40 or the respective elements of the display body D. Thus, in the present embodiment The same effect as in the first embodiment can be achieved. Further, according to this aspect, it is advantageous in that the bonding work between the exterior body 4〇 and the display body D can be facilitated, and the mechanical strength of the display body D can be utilized. The outer casing 40 is reinforced. The anti-reflection (AR) coating 70 (70A, 70B, 70C) of the third embodiment may be added to the display device 100E of the present type. <F: Sixth embodiment> Fig. 13 shows A cross-sectional view of a display device i〇〇F of the sixth embodiment. As shown in FIG. 13 , the display device 1 〇〇f of the present embodiment is additionally characterized by the display device 1 00A of the first embodiment. The characteristic adjustment layer 80 is disposed on the outer side of the display area a 1 of the display body D among the back side surface (that is, the opposite side of the support body 62 and the display body D) covering the reflection preventing plate 60. The light-reflective (light-shielding) film body formed in the form of the region. The property-adjusting layer 80 is a resin material or a chromium (Cr) which is dispersed by a black material such as carbon black (carb〇n-22-200917223 black). The light-shielding metal material is formed. Further, the property adjustment layer 80 can be formed by applying a black paint to the reflection preventing plate 60. The processing method or material or film thickness of the property adjustment layer 80 is adjusted by the property adjustment layer 8G. The light reflection characteristic of the contact surface of the anti-reflection plate 6〇 and the display area of the display body D The manner in which the light reflection characteristics of A1 are slightly uniform is selected, that is, the edge area A2 of the exterior body 40 and the display area A1 of the display body D are formed in the same manner as described above with reference to FIG. In the case of light rays in the wavelength range r of 60 〇 nm or less, the difference between the reflectance of the characteristic adjustment layer 80 and the reflectance of the display region A1 値 Δ is at most 3% (better than 1%), and the characteristics are formed. The layer 80 is adjusted. Since the optical characteristics of the characteristic adjustment layer 80 on the observation side of the outer casing 40 are matched with the display area A1 as described above, even the edge area A2 of the exterior body 40 and the display area A2 of the display body D are light. When the reflection characteristics (reflectance) are different, the same effect as the area of the display region in the appearance of the first embodiment can be exhibited. Accordingly, the present invention is particularly suitable for the case where the optical characteristics of the outer casing 4 are inconsistent with the display area A1 (for example, when the material or processing method of the outer casing 40 is limited). In other words, the outer casing 40 can be made cheaper because the optical conditions required for the outer casing 40 are alleviated. Further, although Fig. 13 shows a configuration in which the characteristic adjustment layer 80 is a single layer, the characteristic adjustment layer 80 may be formed as a laminate of a plurality of layers as shown in Fig. 14 . The characteristic adjustment layer 80 of Fig. 14 is composed of the first layer 81 and the second layer 82, -23-200917223. The first layer 81' is a film body formed of light reflectivity (light blocking property) formed on the back surface side surface (the region on the outer side of the display region A1) of the reflection preventing plate 60. The second layer 82 is laminated on the light-shielding film body of the first layer 81. The first layer 81 and the second layer 82' are formed of a material selected from a light-blocking material such as a resin material in which a black material such as carbon black is dispersed, or a light-shielding metal material such as aluminum or chromium. . For example, it is preferable that the first layer 81 is formed of one of aluminum or chromium, and the second layer 82 is formed of aluminum or chromium. As shown in Fig. 14, a plurality of openings 821 are formed (patterned) in the second layer 8 2 . Each of the openings 821 is uniformly distributed in the plane of the second layer 82. For example, the second layer 82 is formed in the same pattern as the light shielding layer 21 of the display body D. Since the film thickness of the first layer 81 is sufficiently thin, the optical characteristics of the contact surface of the characteristic adjustment layer 80 and the anti-reflection plate 60 are also dependent on the characteristics of the first layer 81 depending on the second layer 82. characteristic. That is, the optical characteristics of the characteristic adjustment layer 80 vary depending on the size or distribution (total number or density) of the openings 8 21 formed in the second layer 82. Therefore, by appropriately selecting the size or distribution of the opening 82 1 of the second layer 82, the light reflection characteristic of the characteristic adjustment layer 80 can be accurately and accurately matched to the display area A 1 of the display body (i.e., the characteristic adjustment layer) The boundary between the 80 and the display area A1 becomes unobtrusive). In addition, in the case where the characteristic adjustment layer 80 is added to the display device 100A of the first embodiment, it is also preferable to add a characteristic adjustment layer to the configuration of FIG. 6 to FIG. 12 (or the configuration of FIG. 15 described later). The composition of 80. Further, although the first layer 81 and the second layer 82 are formed only in the region on the outer side of the display region A1 as illustrated in FIG. 14, the first layer 81 may be formed into the light emitted from the display body D. When the film thickness is sufficiently transmitted to the observation side (for example, when a sufficiently thin aluminum film is formed as the first layer 81), the entire area of the surface on the back side of the anti-reflection prevention plate 60 is formed first. Layer 8 1. According to the above configuration, it is not necessary to perform patterning when the first layer 81 is formed. Further, a method of adjusting the light reflection characteristics of the characteristic adjustment layer 80 by appropriately selecting the film thickness of the characteristic adjustment layer 80 of FIG. 13 or the film thickness of at least one of the first layer 81 and the second layer 82 of FIG. . <G: Modifications> Various modifications can be added to the above various types. Specific deformation patterns are exemplified as follows. Further, two or more types may be arbitrarily selected and combined from the following examples. (1) Modification 1 The form or position of the exterior body 40 is not limited to the above examples. For example, as shown in FIG. 15, an opening portion 42 whose size is slightly equal to the outer shape of the display body D (or slightly larger) may be formed in the outer casing 40 to form the side end surface of the display body D and the inner circumference of the opening portion 42. The display body D is disposed inside the opening portion 4 2 in a facing manner. Further, according to FIG. 15, a configuration in which the observation side surface of the display body D (second substrate 20) and the edge region A2 are located in the same plane has an advantage that the reflection preventing plate 60 can be easily and strongly -25-200917223 The outer casing 40 and the display body D are bonded to the outer casing 40, and the display device 1 (100A, 100B, 100D '100E, 1 〇〇F) can be thinned because the space is omitted. (2) Modification 2 If it is necessary to separately ensure the mechanical strength of the circularly polarizing plate 64 in addition to the manufacture or use of the display device 100, the configuration in which the support 62 is omitted from the preventing plate 60 may be employed. Further, in order to prevent breakage of the circular polarizing plate 64 due to the action, a translucent plate material may be disposed on the side of the circular polarizing plate 64. (3) Modification 3 The configuration common to (dimensions or shapes) of the plurality of display bodies D (DA, DB) of the second embodiment is not essential to the present invention. Also, the size or shape of each display body D may be each display body D. Further, Fig. 6 exemplifies a configuration in which a plurality of display bodies D are spaced apart from each other, and is also suitable for a configuration in which each display body D is disposed without a gap (for example, a configuration in which the side end surface of the display D A is in contact with the side end surface of the display body D B ).

When the power switch 4002 is operated, various information such as an address book or a travel schedule is displayed on the display device 1 . Fig. 22 is a view showing a mode in which the display device 100B of the second embodiment is employed in the on-board meter (panel meter) of the automobile. As shown in Fig. 22, the on-board meter includes a display device 100B in which the display body DA and the display body DB are arranged in the lateral direction, drive circuits 82A and 82B, and a control circuit 84. The drive circuit 82A displays the image instructed from the control circuit 84 on the display body DA. The drive circuit 82B displays the image instructed from the control circuit 84 on the display body DB. The control circuit 84 displays, for example, the speed of the car on the display body DA, and displays a map of the car navigation device (not shown) on the display body DB using a route leading to the destination. The control circuit 84 is connected to detect a detector (not shown) for detecting an abnormality of the display body DA or the display body DB. For example, it is suitable to use a temperature sensing device that detects the temperature of the display body DA or the display body DB, an ammeter that detects the current flowing to the light-emitting layer 15 of each pixel P, or a luminance meter that measures the brightness of each pixel P. As a detector. The control circuit 84 determines that an abnormality has occurred in the display body DA or the display body DB and performs the specific control in the case where the detection 値 of the detector exceeds (or falls below) the specified 闳. For example, when an abnormality of the display body DA is detected, the control circuit -29-200917223 circuit 84 displays the speed of the car displayed on the display body DA on the display body DB. According to the above aspect, there is an advantage that both the display body DA and the display body DB can display various images without an abnormality. On the other hand, when an abnormality occurs in one of the display body DA or the display body DB, Changing the display side of the desired information to the other display body D' can reliably display the information (such as speed) with a high priority.
