發光顯示面板，已提案一種藉由轉換發光色即可轉換發光 顯示圖案之發光顯示面板（參閱例如發明專利文獻1 )。 第14圖係展示傳統發光顯示面板之顯示層之一實例平 面模式圖。參閱顯示層之平面模式圖的第14(a)圖與其局 部放大圖的第1 4 ( b )圖，顯示層1 1 0係具有供透射來自紅 色光源之光的發光顯示圖案lllr與供透射來自藍色光源之 光的發光顯示圖案111b，且其發光顯示圖案lllr與發光顯

200903402 (發明專利文獻1 ) w〇 2006/ 1 1 5 〇31號 【發明內容】 〔發明所欲解決之技術問題〕 然而，如上所述之傳統的發光顯示面板，卻必須對於 重複發光顯示圖案之處使各圖案以不至於重畳供透射不同 色之網點的方式配置於顯示層，因此要求高位置對準精確 度。 此外，由於以能使各圖案之網點不至於重畳的方式配 置，在重複發光顯示圖案之處，其發光量勢必因分攤發光 面積而減少。例如，若爲以兩色之發光圖案所構成者時， 則其各發光面積在重複發光顯示圖案之處，則將分別變成 爲 5 0%。 並且，爲使各圖案之網點不至於重畳，卻必須在網點 之間設置不至於透射複數之發光色的微細境界領域。因此 造成各發光顯示面積則更加減少之結果，使得照射光之損 失增大。例如，在兩色之發光顯示圖案重複的情況下，其 各發光面積在重複發光顯示圖案之處，則將分別變成爲小 於 5 0%。 有鑑於此，本發明則以獲得一種在重複發光顯示圖案 之處，使不同的發光色可充分有效地發光顯示之發光顯示 面板爲其課題。 本發明之其他課題，由本發明之說明當可明暸。 〔解決課題之手段〕 爲解決如上所述之技術問題，本發明之一模式的發光 200903402 顯示面板，係由具有複數個發光顯示圖案之顯示層、與配 置於該顯示層之背面側用於對該顯示層照射光之光照射手 段（means

Description of the Invention: [Technical Field] The present invention relates to an indicator for a small electronic device such as a car for use in home appliances, audio equipment, portable telephones, etc. A light-emitting display panel in which a pattern such as a mark is displayed. [Prior Art] The inventors of the present invention have two or more different kinds of light beams composed of two or more light sources having different light-emitting colors and materials having different wavelengths which are transmitted by light from the light source in the display layer. In a light-emitting display panel comprising a display pattern, a light-emitting display panel in which a light-emitting display pattern can be converted by converting a light-emitting color has been proposed (see, for example, Patent Document 1). Fig. 14 is a diagram showing an example of a planar view of a display layer of a conventional light-emitting display panel. Referring to Fig. 14(a) of the planar mode diagram of the display layer and Fig. 14(b) of the partially enlarged view, the display layer 110 has a light-emitting display pattern 111r for transmitting light from the red light source and for transmission from The light-emitting display pattern 111b of the light of the blue light source, and the light-emitting display pattern 111r and the light-emitting display pattern 111b are overlapped in the repeating domain 116. The 14th (c) diagram shows the text displayed when the red light source is lit, and the 1st 4th (d) diagram shows the text displayed when the blue light source is lit. In the conventional light-emitting display panel, two or more light-emitting display patterns exist in the same region, and in the case where there is a place where the respective patterns are repeated, the light-emitting display patterns are formed by dots or matrices and the respective patterns are combined. In order to convert the illuminating colors, the respective illuminating display patterns can be independently and effectively displayed. 200903402 (Patent Document 1) W〇2006/1 1 5 〇31 [Invention] [Technical Problem to be Solved by the Invention] However, the conventional light-emitting display panel as described above must be used for a repeated light-emitting display pattern. The pattern is disposed on the display layer so as not to overlap the dots for transmitting different colors, and thus high alignment accuracy is required. Further, since the dots of the respective patterns are arranged so as not to overlap, the amount of light emitted from the place where the light-emitting display pattern is repeated is inevitably reduced by the distribution of the light-emitting area. For example, if it is composed of two color illuminating patterns, the respective illuminating areas will be 50% when the illuminating display pattern is repeated. Moreover, in order to make the dots of the respective patterns do not overlap, it is necessary to provide a fine boundary area between the dots which does not transmit a plurality of luminescent colors. As a result, the area of each of the luminescent display areas is further reduced, resulting in an increase in the loss of the illuminating light. For example, in the case where the two-color light-emitting display patterns are repeated, the respective light-emitting areas are respectively reduced to less than 50% at the place where the light-emitting display patterns are repeated. In view of the above, the present invention has an object of obtaining a light-emitting display panel in which different luminescent colors can be sufficiently efficiently illuminated and displayed at the same time as the illuminating display pattern is repeated. Other problems of the present invention will become apparent from the description of the present invention. [Means for Solving the Problem] In order to solve the above-described technical problems, a light-emitting panel 200903402 display panel according to one aspect of the present invention is provided by a display layer having a plurality of light-emitting display patterns and a rear side disposed on the back side of the display layer. The display layer is configured to emit light by means of light, and the light irradiation means has a light source for N colors (N-type positive integers of 2 or more) in which the luminescent colores are different from each other, and the display layer is each a single color display panel having a single color display pattern formed by a material that can transmit light of a single color of the N colors, and a light-emitting color panel that converts the light-emitting color of the light source to independently display one single color display pattern, wherein The single color display pattern includes a repeating color display field repeated with at least one of the other single color display patterns, and the single color display pattern is subtracted from the single color display pattern including the repeated color display field One of the areas of the display field is an individual color display field, and the brightness between the repeated color display fields satisfies the relationship of the formula (1): 0.5 ^ (cE s/cE〇l )^1.5 (1) In the formula (1), the cEs are the individual regions of the region in which the repeated color display region is subtracted in the single color display pattern when the c-color source is lit, and the color display region The brightness, cE0L is the brightness of the repeated color display field in the single color display pattern when the c color source is lit. In the formula (1), the C color system means the luminescent color of the light source which should be transmitted through the repeated color display field. The c color is 2 or more and the color of N or less. The formula (1) holds for the plural c color. 200903402, for example, using different light sources of red and blue colors and forming different single color display patterns with materials that can only individually transmit the light-emitting wavelengths of the respective light sources, if the repeated color display fields of the single color display pattern are repeated to transmit red When the light-emitting display panel of the blue/blue light-emitting color forms the obtained light-emitting display panel, the red light-emitting color is transmitted by both the red individual color display domain portion and the red-blue repeating color display region which are only for transmitting red light when the red light is emitted. Display the pattern in a single red color. Further, in the case of blue light emission, blue light is transmitted by both the blue individual color display field for transmitting only blue light and the red blue repeating color display field to display a blue single color display pattern. The c color represented by the formula (1) in this example is a red light emitted by a red light source and a blue light emitted by a blue light source. Further, the equation (1) holds for the two colors of the red and the blue. In one embodiment of the present invention, the light irradiation means as described above in the light-emitting display panel may be a light guide body having a light-emitting means on the back side and a light source disposed in the light-injecting portion of the light guide body. . According to this embodiment mode, the thickness of the light-emitting display panel can be made thin. In particular, the light irradiation means of the present invention may be constituted by a light source and directly illuminating the light emitted from the light source to the display layer. In other embodiments of the present invention, the light-emitting display panel may be configured to prevent the pattern from being exposed on the surface side of the display layer as described above to prevent reflection of external light when the light source is not lit. The illuminated display reveals the pattern. In this embodiment mode, when the light source is not turned on, the single color display pattern can be more effectively and effectively hidden. By configuring the pattern preventing exposure means, it is possible to increase the effect of expressing different single color display patterns only by transmitted light. In another embodiment mode of the present invention, the light-emitting means uses a light-emitting display panel of a light guide and a light source, and a light absorbing means may be disposed on the back side of the light guide. The light incident on the light-emitting display panel from the outside also has a single color display pattern of the transmissive display layer, and is transmitted through the light guide body and reflected to the structure located on the lower side of the light guide body to return to the surface side. By providing a light absorbing means for absorbing incident light from the outside on the back side of the light guide body, the single color display 75 pattern of 75 layers can be more effectively and effectively hidden. This hidden effect is especially effective when the light source is not lit. The light absorbing means may be a film or a plate which is attached to the back surface of the light guide body or is separated from the light guide body and disposed on the back side of the light guide body. Alternatively, it may be a black paint applied to the frame on which the light guide body is placed. The film or sheet may be black, or fine irregularities may be formed on the surface to have a function of suppressing reflection. In still another embodiment of the present invention, the light-emitting display panel is provided with an anti-reflection layer between the display layer as described above and the light-illuminating means as described above. According to this embodiment mode, the reflection of external light can be more effectively and effectively eliminated. In still another embodiment mode of the present invention, the light-emitting display panel may be an anti-reflection layer provided on the surface and/or the back surface of the light guide body as described above. According to this embodiment mode, the reflection of external light can be eliminated more efficiently. 200903402 The above-described embodiments of the present invention and the components of the implementation of the modules are implemented in combination as far as practicable. [Effect of the Invention] The light-emitting display panel of the present invention can clearly display a single color display pattern because it can illuminate each of the different single patterns and repeat the respective light-emitting colors. Further, large luminescence can be obtained. Further, the light of the light source can be utilized sufficiently efficiently for the light-emitting display.

The box. Further, the light guide body 32 may be a flexible one, for example, an elastic film made of enamel resin. The light-emitting means is a means for emitting light which is guided to the depth by the reflection (full reflection) of the inner surface of the light guide body 3 2 toward the display layer 10, for example, a fine uneven shape 3 3 is formed. The fine concavo-convex shape can be obtained by using a distance of a distance from the light source to obtain an equal stomach % 〇 fine concavo-convex shape, and a mat-style embossed surface can be used, or Use a fine microlens shape. By using a microlens or the like to control the shape of the concavo-convex shape, the reflection characteristics of the light can be improved, and the luminous effect of # -11- 200903402 can be obtained. The fine concavo-convex shape is generally given a shape in advance to the molding die of the light guide 32, and then transferred at the time of molding. Further, instead of directly imparting a shape to the molding die, a transfer foil having a shape in which a fine uneven shape is provided on the base sheet is used, and then, when the light guide body 3 2 is formed, the above-described transfer is performed. The printing foil is inserted into the mold to transfer the fine uneven shape to the light guiding body at the same time as the forming. The light-emitting means is not limited to being formed by forming a fine uneven shape on the back side of the light guide body 3, and may be a point printer to which light-diffusion is applied to the light guide body 32. Further, the light-emitting means is not directly reflected by the fine uneven shape or dot printing as described above, but may be directed toward the display layer 10 by a reflecting plate such as a lower white sheet once transmitted. Light out. Further, in order to cause the light-emitting surface of the light guide body 32 to emit light in a comprehensive manner and to partially emit light, it is preferable to provide a light-emitting means depending on the position of the light-emitting region, and to correspond to the light-emitting means. Where the area is located, no light exit means are provided. Thereby, it is possible to use it sufficiently efficiently without causing the light from the light source to emit light. Further, the light incident portion of the light guide body 32 is not limited to the end portion of the light guide body, and may be the side surface or the lower portion of the light guide body 32. Fig. 3 is a cross-sectional view showing another specific configuration of the light-emitting display panel of the present invention. The third light-emitting display panel 3 is provided with a light source 31 on the back side of the display layer 10. The light source 31 is the light irradiation means 30. Between the display layer 1 〇 and the light source 31, a diffusion plate for diffusing light may be disposed. -12- 200903402 The light source 3 1 included in the light irradiation means 30 as described above can use LEDs of different colors having different emission colors. Ν is a positive integer of 2 or more. The LED of the twilight can be independently driven by lighting, eliminating lights, etc. according to each illuminating color. Among them, the total number of LEDs can also be more than N. For example, it is possible to arrange one of the R (red) element and the G (green) element, and to configure only two B (blue) elements to configure a total of four LEDs. In this case, n is 3. The LEDs as the light source 31 may be arranged in a package arrangement in which the respective illuminating colors are different in the light incident portion of the light guide body 32. Since the side-emitting type LED is generally small and thin, it is suitable as a light source for a light-emitting display panel in which the thickness of the entire unit is required to be thin. The LED package also has a package in which components such as R (red), G (green), and B (blue) of different luminescent colors are packaged. A more space-saving design can be achieved by using these LED packages obtained by summing up a plurality of components. The luminescent color of the light source 31 is not limited to R, G, and B, and may be, for example, yellow, orange, or the like. The illuminating color group thus obtained can appropriately select a plurality of luminescent colors. The light of a single color emitted by each light source is not limited to, for example, a light source having a wavelength range of 100 nm or less, and may be, for example, light having a wavelength range of 200 nm. The term "wavelength range" means that the wavelength of the light source of the light source is from the wavelength of the low wavelength side which can provide the strongest wavelength intensity of 15% up to the wavelength of the high wavelength side which can provide the strongest wavelength intensity of 5%. The wavelength range. The wavelength range of the single-color light that can be used varies depending on the spectrum of light transmitted by the single-color display pattern (described later) and the number of colors (N) of the light source used in the same light-emitting display panel. In particular, if the wavelength of the light of a single color is narrow, the design of a single color display pattern, a repeating color display pattern, or the like of the light-emitting display panel can be easily performed. Based on these viewpoints and the reason that the power consumption is small and small, etc., the light source is suitable as a single-color LED. However, the light source 31 is not limited to the LED, and a fluorescent single-color fluorescent lamp or the like may be used. Further, the light source 31 may be a light source that combines a white light source (e.g., a tungsten lamp) with a diffraction grating, a crucible, or the like to emit light that reduces the spectral width of the light. The display layer 10 includes a single color display pattern 11 formed of a material that transmits light of a single color. The single color display pattern corresponds to the respective lights of the N color light emitted by the light source 31, and each of the monochromatic lights includes at least one single color display pattern. For example, in the case where the light source 31 is three colors of light red (R), green (G), and blue (B), a single color display pattern composed of a material that transmits only red (R) light is disposed. A single color display pattern composed of a material that transmits only green (G) light is disposed, and two single color display patterns composed of materials that transmit only blue (B) color are disposed, and a total of four light-emitting displays can be arranged. pattern. Figure 4 is a diagram showing an example planar mode of the display layer. Fig. 4(a) shows a plan view of the layer l〇a, and Fig. 14(b) shows a partial enlarged view. The display layer 10a is combined with a light irradiation means including a blue LED and a red LED as a light source. Referring to Figure 4 (a), the display layer 1 〇 a will display blue without a single color display pattern lib 舆 red display a single color display pattern llr is formed in a region. The blue display single color display pattern lib is in the shape of -14- 200903402 English letter S. The red display single color display pattern llr is in the shape of an English letter N. The blue display single color display pattern lib and the red display single color display pattern llr make a part of the surface heavy. That is, referring to Figure 4(b), a repeating color display field with two repeated single color display patterns 1 6 * 4 (c) shows the display layer when the red light source is illuminated, Figure 4 (d) Shows the display layer when the blue light source is illuminated. As shown in Fig. 4(c), in the display layer 1 〇a, when the red light source (red LED) emits light, the character N is displayed. As shown in Fig. 4(d), in the display layer 10a, when the blue light source (blue LED) emits light, the character of S is displayed. Fig. 5 is an explanatory diagram for explaining a single color display pattern and a repeating color display field. In the display layer l〇b, the blue display single color display pattern lib and the red display single color display pattern llr are partially repeated. This repeating region is a blue red repeat display field 16br. The area obtained by the blue color display single display pattern lib minus the blue red repeat display field 1 6br is displayed in the blue individual color display field 1 7b. The area obtained by the red color display single color display pattern 1 1 r minus the blue red repeat display field 1 6br is the red individual color display field 1 7 Γ 〇 where the blue LED is illuminated and the area to be light-transmitted is blue The color individual color display field 1 7b and the blue red repeat display field 1 6br, that is, the single color display pattern 1 1 b is displayed in blue. Further, the area in which the red LED is illuminated to be transparently displayed is the red individual color display field 1 7r and the blue red repeated display field 16br, that is, the single color display pattern 1 lb is displayed in red. Therefore, with respect to the blue LED illuminating color of a specific color, the luminance b E s of the material constituting the blue individual color 200903402 display field 1 7 b and the brightness b E 〇l of the material constituting the blue red repeat display field 16 br Relationship is satisfied (1 - 1 :

This line 24 represents the luminescence spectrum of the blue LED and the luminescence spectrum indicated by the broken line 25. The luminescence spectrum of the blue LED has a luminous intensity of 450 nm. At this wavelength, the transmission color of the blue individual color display field 17b is red, and the transmission rate of the field 1 6br is greater than either of them. That is, the light emitted by the blue LED can be substantially transmitted through the blue individual color display field 17b and the blue red.

Blue red weighs 16br. The relationship between (rEs/rEOL) is roughly 1. For the material constituting the single color display pattern and the above-mentioned as described above, a person (for example, an ink) containing a pigment or a dye material in the resin binder can be used. In addition, the vicinity of the virtual red LED is the replacement 21 and the blue is 50%. The transmittance is shown below. The field is 1 6 br. The field 1 6 br is repeated in the same process color, and the vicinity is the most every 22 and the blue I 50%. The rate is 16br.

200903402 成之抗反射層。 此等之抗反射層之製法，則有真空蒸鑛法、濺鍍法、 離子鍍覆法等。或也有將金屬醇化物、金屬螯合物等之有 機金屬化合物以浸漬法或印刷法、塗布法等塗布在基體薄 片上，其後則以光照射或乾燥形成金屬氧化物皮膜以製得 抗反射層之方法。 抗反射層之厚度，可在0.01至2#m之範圍下適當地 選擇。此等之膜厚可從低折射材料之折射率適當地選擇成 能符合通式nxd = λ/4或通式nxd = 3λ/4 (但是η是代表低 折射材料之折射率、d是代表低折射材料之膜厚、λ是代表 低反射中心波長。）即可。 抗反射膜可例示經在聚對苯二甲酸乙二醇酯等之具有 優越的光透射性的薄膜之表面，以如上所述之方法形成抗 反射層所獲得者。低反射薄膜則可例示經在聚對苯二甲酸 乙二醇酯等之具有優越的光透射性的薄膜之表面，將由氟 化鎂、氧化矽等之低折射材料所構成之金屬氧化物以單體 或與由高折射材料所構成之金屬氧化物一起加以蒸鍍所積 層獲得者、或經塗布氟樹脂等之低折射材料所獲得者等。 爲說明抗反射層，茲舉一實例就在配置於與顯示層之 顯示面成相反側的光源使用會發光紅色的LED與會發光藍 色的LED，並將以能透射紅色之發光色且能遮光藍色之發 光色的材料所構成之圖案、與以能透射藍色之發光色且能 遮光紅色之發光色的材料所構成之圖案構成在一個顯示面 所獲得之發光顯示面板進行考察。例如，紅色透射部之反 200903402 射率爲15.5%、藍色透射部之反射率爲1 1.5%時，若在顯示 面之單側面形成抗反射層時，則紅色透射部之反射率則爲 1 2.6%、藍色透射部之反射率則爲1 0.4%，係可分別減少約 3%。 亦即，在未形成抗反射層的情況下，配置於顯示層之 發光面側的半透射層若設定其透射率爲24 %時，即能遮蔽在 光源並未點燈狀態下之各顯示圖案。在另一方面，在經形 成抗反射層的情況下，其半透射層若設定其透射率爲34% 時，即能遮蔽光源並未點燈狀態下之各顯示圖案。如上所 述，藉由形成抗反射層，半透射層之透射率即可提高至34% 。因此，在使用相同亮度之光源的情況下，藉由形成抗反 射層，與未形成抗反射層的情況相比較，即可提高顯示亮 度 42%。 第11圖係展示本發明之其他發光顯示面板之構成模式 截面圖。第七發光顯示面板7係在導光體之表面設有抗反 射層71。顯示層10、導光體32等係與使用第2圖加以說 明的第二發光顯示面板相同。 參閱第10圖，當外光65入光於發光顯示面板時，外 光65則在導光體32之表面34反射。以箭頭標記76表示 該反射光。此外，外光6 5係在導光體3 2之背面3 5反射。 以箭頭標記77表示該反射光。此等之反射光（箭頭標記76 與箭頭標記77 )，由於其係透射單一色顯示圖案1 1而出光 於表面側，因此產生色。以如上所述之方式在導光體32之 表面34、背面35所反射之光，會使形成於顯示層1〇之單 -25 - 200903402 —色顯示圖案11暴露。 第七發光顯示面板7係藉由抗反射層71來防止單一色 顯示圖案11暴露。抗反射層71也可設置於導光體32之背 面35。此外’抗反射層71也可設置於導光體32之表面34 及背面3 5之兩面。 抗反射層7 1之形成材料、形成方法等，係與在抗反射 層6 1加以說明者相同。 在本發明之顯示層10中，未具單一色顯示圖案之平面 區域也可設置遮光層。藉由形成遮光層，將可提高單一色 顯示圖案之對比。遮光層可舉出黑色墨或白色墨等。此外 ，藉由重疊組合複數層費層也可提高遮光功效。 此外，在光照射手段使用導光體與光源的情況下，若 形成金屬蒸鍍等之反射層作爲遮光層時，則可使照射在不 需要發光的部份之光線返回導光體，藉此即可在不至於使 來自光源之光白費地發光下充分有效地使用。 在顯示層之最表面也可形成硬質塗層。 若在製品採用本發明之發光顯示面板時，則可以簡便 、堅牢、廉價的構成來實現先前以液晶顯示器所表現的花 樣之轉換。由於可在相同面區域顯示出複數之花樣，可節 省花樣顯示域。並且，可使其花樣明確表達。第1 2圖係以 本發明之發光顯示面板實現文字顯示所轉換之實施例。圖 中之（a)係顯示層之平面模式圖，（b)係在光源非發光時 之發光顯示面板'(c )係在紅色光源發光時之發光顯示面 板、（d )係在藍色光源發光時之發光顯示面板。 -26 -

As the material constituting the light-emitting display pattern as described above, an optical film in which a plurality of layers are laminated can be used. For example, a light interference film obtained by laminating a plurality of inorganic materials such as titanium oxide or cerium oxide by a method such as coating, dipping, vapor deposition or sputtering can be used for patterning. Further, in the present invention, the "wavelength transmissive in the light from the light-emitting means 30" means that the wavelength of the direction perpendicular to the display panel can be transmitted, and does not mean that it is refracted by the transmissive optical film. The wavelength is the same or different for its materials. The material constituting the repeating color display region, for example, an ink of an intermediate color constituting the ink of the single color display 200903402 can be used. The ink can also be printed or coated on the full surface of the repeating color display field (so-called all coating) or printed on dots. When the brightness is a preferable ratio, for example, the amount of the pigment or dye in the resin binder may be increased or decreased, or the coating film thickness of the ink may be increased or decreased. Further, the display layer 1 can be disposed on one side of the light guide body 32 by direct printing or painting. Further, the display layer 10 is formed on the single surface of the light guide body 32 simultaneously with the formation of the light guide body 32 by using a transfer foil or a mosaic film and being inserted into the mold when the light guide body 32 is formed. Further, the display layer 10 may be laminated on the single surface of the light guide body 32 in a transparent film, or may be disposed only on the light guide body 32. Further, when the display layer 10 does not use the light guide 32, it is formed only on the transparent film. Also, the wavelength of the so-called transmissive single-color transmission pattern 11 does not need to correspond completely to the wavelength domain illuminated by the light source 31. For example, it may be only the wavelength of a narrower domain on the side closer to the green among the wavelength domains illuminated by the red LED, in which case the luminescent color displayed in the illuminating display pattern will become the red LED. The illuminating colors are different. Since the light source 31 as described above can be independently driven for each illuminating color, the wavelength of the light illuminating the display layer 1 can be changed at any time by selectively driving the light source 31. In the present invention, the driving of the light source 31 means that the amount of light emitted, the extinction, and the light is changed. The driving of the light source 31 can be implemented by varying the amount of power supplied to the light source 31, or by mechanical means such as a visor or a slit. Since two or more single color display patterns composed of materials having different wavelengths that can be transmitted are formed on the display layer 10, a single color pattern can be selected by changing the illumination color from the light irradiation means -19-200903402. Fig. 7 is a schematic cross-sectional view showing the configuration of another light-emitting display panel of the present invention. The fourth light-emitting display panel 4 is provided with a semi-transmissive layer 41 on the surface side of the display layer 10. The semi-transmissive layer 41 is a pattern preventing means. The display layer 10, the light irradiation means 30, and the like are the same as those of the first light-emitting display panel described in Fig. 1. When the light-emitting display panel is used in a place where there is external light, the external light 42 is incident on the light-emitting display panel by the display layer 10, reflected by the light-irradiating means 30 on the back side, and transmitted through the display layer 10 to emit light. . Since there is a single color display pattern 11 on the display layer 10, the light originating from the external light is bound to cause a single color to be exposed. In the fourth light-emitting display panel, the external light is transmitted through the semi-transmissive layer 41 twice as it enters light and when it exits light. For example, assuming that the light transmittance of the semi-transmissive layer is 30%, the light intensity of the external light becomes 0.09 (0.3x0.3) as compared with the case where the semi-transmissive layer is not provided. Therefore, the exposure of the single-color display pattern 11 originating from the external light 42 can be prevented. In this case, with respect to the light showing the single color display pattern 11 illuminated by the light source 31, although it is necessary to pass through the semi-transmissive layer 4 1, the light system transmits only the semi-transmissive layer 41 once. In the example as described above, light is emitted on the surface side at a transmittance of 30%. The light transmittance of the semi-transmissive layer is preferably set to 20 to 40%. The so-called "light transmittance" means the transmittance in the entire wavelength range in the wavelength range of visible light (from 360 nm to 830 nm). The semi-transmissive layer is a film obtained by attaching a printed semi-transmissive pattern to at least one side of a smoke-adjusting resin or a transparent resin plate or a glass plate to obtain a film of -20-200903402. Further, a film obtained by using a molded article of a transparent resin and printing a semi-transmissive pattern on at least one side at the time of molding may be inserted into the molding die, and the pattern may be transferred to the molded article at the same time as the molding. The semi-transmissive pattern is for those who have applied smoke to the printer or who have semi-vapor evaporated the metal. For other methods of preventing pattern exposure, a circular polarizing layer can be used. The circular polarizing plate layer has a function of blocking the light emitted by the difference between the circular light of the light emitted from the external light and the light emitted from the external light. The circular polarizing plate layer may also be one in which a circular polarizing plate is bonded to either one of a transparent resin plate or a glass plate. The material of the transparent resin sheet is acrylic acid, polycarbonate, polystyrene, polyolefin resin or the like. The pattern preventing means may be disposed on the surface side of the display layer 1 from the display layer, or may be disposed on the surface side of the display layer 10 in a mode integrated with the display layer. By providing the pattern preventing layer to be exposed, the following effects can be obtained (1) In the state where the light source is not lit, the exposure of the plural single color display pattern 11 can be prevented. (2) In the state of lighting the light source 31 of the single color, the single color display pattern selected by the wavelength of the light source can be illuminated, and the unselected single color display pattern can be prevented from being exposed by the reflection of the external light. Fig. 8 is a cross-sectional view showing the configuration of another light-emitting display panel of the present invention. The fifth light-emitting display panel 5 includes a light-guiding body 32 and light sources 3 1 b, 3 1 γ, and 3 1 g, and has a light-absorbing sheet 5 1 disposed on the back side 200903402 of the light guide body 3 2 . . When the light-emitting display panel is used in a place where there is external light, the external light 5 2 is incident on the light-emitting display panel by the display layer 10, and transmits the light guide body 32 and the frame and the frame of the fifth light-emitting display panel 5 are disposed. The structure or the like reflects and transmits the display layer 1 to emit light. Since the single-color display pattern 11 is provided on the display layer 1 ,, the light originating from the external light 52 is bound to cause the single color display pattern to be exposed. Therefore, in order to suppress the reflection of the external light 52, the light absorbing sheet 51 is disposed. The light absorbing sheet 51 is a black film. The light absorbing means is attached to the back surface of the light guide body, or may be a film or a plate disposed on the back side of the light guide body while being spaced apart from the light guide body. Further, a black painter may be applied to the frame of the frame in which the light guide body is provided. The film or the sheet may also be black or have fine irregularities formed on the surface thereof to have a function of suppressing reflection. By setting the light absorbing means, the following effects can be obtained: (1) In the state where the light source is not lit, the plural single color display pattern 11 can be prevented from being exposed. (2) In the state in which the light source 3 1 is turned on, the single color display pattern selected by the wavelength of the light source is illuminated, and the unselected single color display pattern is prevented from being exposed by reflection of external light. Fig. 9 is a schematic cross-sectional view showing the configuration of another light-emitting display panel of the present invention. The sixth light-emitting display panel 6 is provided with an anti-reflection layer 61 on the back surface of the single-color display pattern 11. The display layer 10, the light irradiation means 30, and the like are the same as those of the first light-emitting display panel described in the first drawing. -22- 200903402 The first diagram is used to explain the external light incident on the light-emitting display panel and its reflection. Referring to Fig. 10, when the external light 65 enters the light-emitting display panel, the external light 65 is reflected on the surface 14 of the single color display pattern U. This reflected light is indicated by arrow mark 66. The reflected light (arrow mark 66) causes a portion of the wavelength domain to be absorbed to produce color due to the action of the single color display pattern. The external light 6 5 is reflected by the back surface 1 5 of the single color display pattern 1 1 . The reflected light is indicated by an arrow mark 67. This reflected light (arrow mark 67) produces a color by transmitting a single color display pattern. As described above, the light reflected on the surface 14 and the back surface 15 of the single color display pattern 11 can expose the single color display pattern 11 formed on the display layer 10. The sixth light-emitting display panel 6 prevents the single color display pattern 11 from being exposed by the anti-reflection layer 61. The antireflection layer 61 may also be formed by coating a low refractive material, or printing, or attaching an antireflection film or a low reflection film. As the low refractive material used for the antireflection layer, a metal oxide such as magnesium fluoride or ruthenium oxide can be used. Further, an organometallic compound containing at least one of cerium oxide or an organic polyoxyalkylene can also be used. Further, a porous body of such an organometallic compound can also be used. Further, an organic compound such as a fluorine-based synthetic resin can also be used. The antireflection layer can be used as a titanium oxide layer or a cerium oxide, in addition to dispersing cerium oxide or aluminum oxide having fine pores in yttrium oxide and using it as a single layer, or using magnesium fluoride as a single layer. The antireflection layer composed of two layers of the layer is used, or as an antireflection layer composed of four layers of a titanium oxide layer/oxidized sand layer/titanium oxide layer/yttria layer, etc., and a multi-layered multilayer structure is used. Anti-reflective layer. Examples of the method for producing the antireflection layer include a vacuum distillation method, a sputtering method, and an ion plating method. Or an organometallic compound such as a metal alkoxide or a metal chelate compound may be applied onto a base sheet by a dipping method, a printing method, a coating method, or the like, and then a metal oxide film may be formed by light irradiation or drying to obtain an antireflection. Layer method. The thickness of the antireflection layer can be appropriately selected in the range of 0.01 to 2 #m. These film thicknesses can be appropriately selected from the refractive index of the low refractive material to conform to the general formula nxd = λ/4 or the general formula nxd = 3λ/4 (but η represents the refractive index of the low refractive material, and d represents low The film thickness of the refractive material, λ is the wavelength of the low reflection center.). The antireflection film can be exemplified by the formation of an antireflection layer by the method described above on the surface of a film having excellent light transmittance such as polyethylene terephthalate. The low-reflection film can be exemplified by a metal oxide composed of a low-refractive material such as magnesium fluoride or cerium oxide on the surface of a film having excellent light transmittance such as polyethylene terephthalate. The body is obtained by vapor deposition of a metal oxide composed of a high refractive material, or by a low refractive material such as a fluororesin. To illustrate the anti-reflection layer, an example of a light source disposed on the opposite side of the display surface of the display layer uses a red LED that emits light and a blue LED that emits light, and is capable of transmitting red light and can be shielded from light. A pattern formed of a material having a blue luminescent color and a pattern composed of a material capable of transmitting a blue luminescent color and capable of absorbing a red luminescent color constitute a luminescent display panel obtained on one display surface. For example, when the inverse transmittance of the red transmissive portion is 15.5% and the reflectance of the blue transmissive portion is 1 1.5%, when the antireflection layer is formed on one side of the display surface, the reflectance of the red transmissive portion is 1 The reflectance of the 2.6% blue transmission portion was 10.4%, which was reduced by about 3%. In other words, when the anti-reflection layer is not formed, if the semi-transmissive layer disposed on the light-emitting surface side of the display layer has a transmittance of 24%, the display pattern can be shielded from the light source without being turned on. . On the other hand, in the case where the antireflection layer is formed, if the transmissive layer is set to have a transmittance of 34%, it is possible to shield the display patterns in the state in which the light source is not turned on. As described above, by forming the antireflection layer, the transmittance of the semi-transmissive layer can be increased to 34%. Therefore, in the case of using a light source of the same brightness, by forming the anti-reflection layer, the display brightness can be improved by 42% as compared with the case where the anti-reflection layer is not formed. Fig. 11 is a cross-sectional view showing the constitution of another light-emitting display panel of the present invention. The seventh light-emitting display panel 7 is provided with an anti-reflection layer 71 on the surface of the light guide body. The display layer 10, the light guide 32, and the like are the same as the second light-emitting display panel described using Fig. 2 . Referring to Fig. 10, when the external light 65 enters the light-emitting display panel, the external light 65 is reflected on the surface 34 of the light guide body 32. The reflected light is indicated by an arrow mark 76. Further, the external light 65 is reflected on the back surface 35 of the light guide body 3 2 . The reflected light is indicated by an arrow mark 77. The reflected light (arrow mark 76 and arrow mark 77) is emitted on the surface side because it transmits the single color display pattern 1 1 , and thus a color is generated. The light reflected on the surface 34 and the back surface 35 of the light guide body 32 as described above exposes the single-25 - 200903402 - color display pattern 11 formed on the display layer 1 . The seventh light-emitting display panel 7 prevents the single color display pattern 11 from being exposed by the anti-reflection layer 71. The anti-reflection layer 71 may also be disposed on the back surface 35 of the light guide body 32. Further, the anti-reflection layer 71 may be provided on both surfaces 34 and 35 of the light guide 32. The material for forming the antireflection layer 171, the method of forming the film, and the like are the same as those described for the antireflection layer 61. In the display layer 10 of the present invention, a light-shielding layer may be provided in a planar region which does not have a single color display pattern. By forming the light shielding layer, the contrast of the single color display pattern can be improved. The light shielding layer may be black ink or white ink. In addition, the shading effect can also be improved by overlapping a plurality of layer layers. Further, when a light guide and a light source are used in the light irradiation means, when a reflection layer such as metal deposition is formed as a light shielding layer, light irradiated to a portion where illumination is not required can be returned to the light guide body. It can be used fully and effectively without causing the light from the light source to emit light. A hard coat layer can also be formed on the outermost surface of the display layer. When the light-emitting display panel of the present invention is used in the product, the conversion of the pattern previously exhibited by the liquid crystal display can be realized in a simple, firm, and inexpensive configuration. The pattern display field can be saved because a plurality of patterns can be displayed in the same area. Also, the pattern can be clearly expressed.
