201002123 六、發明說明: 【發明所屬之技術領域】 本發明係關於有機電激發光顯示器(以下,亦稱作「 有機EL顯示器」)。更詳細係有關本發明之有機El顯 示器乃從有機EL元件部射出於外部的光則未經由視野角 而呈現不同的發色光之有機EL顯示器。本發明係關於如 此之有機EL顯示器之製造方法。 【先前技術】 目前,液晶顯示器及有機EL顯示器等之顯示裝置乃 作爲行動電話,個人電腦,數位影印機,及列印機等之電 子機器的顯示部而加以使用。 對於上述顯示裝置的發光形態,係有自發光型與非發 光型。自發光型係適用於電激發光元件(EL元件),場 發射顯示器(FED ),及陰極射線管(CRT )等。對此, 非發光型係使用於液晶顯示元件等。 另外’對於上述顯示裝置的彩色顯示方式,係有實現 紅、綠、藍之3原色發光的多彩方式或全彩方式。在此等 方式,多使用於發光元件的出光面與畫像面之間,使彩色 濾光片層介入存在的手段。如根據該手段,可選擇性地射 出來自發光元件的特定波長,使個3原色的發光之色純度 提昇,將畫像顯示作爲高品質。 在如上述之顯示裝置之中,特別是對於有機EL顯示 器,提案有以下的技術。 -5- 201002123 對於專利文獻1係揭示有具有有機EL材料 收在有機EL·材料部的發光,將可視光的螢光發 材料部之有機EL元件部。此元件係由具備於螢 含有螢光材料之色變換濾光片者,將在有機EL 發光’在螢光材料部吸收,將可視光域的螢光發 色變換方式者。 在專利文獻1所揭示之技術中,有機EL元 光色並不限於白色。因此,比較於以往,可將亮 機EL元件部適用於光源,例如,經由使用藍色 機EL元件部之色變換方式,可將藍色光波長變 光或紅色光者。 近年來,眾所注目如專利文獻1所揭示之有 螢光材料色素之螢光材料部高精細地作爲圖案化 用從發光體的近紫外線光可視光的波長範圍之弱 色變換方式全採顯示器。 使用於該色變換方式之色變換層(相當於螢 )係主要可根據經由光阻劑之濕處理,或經由蒸 處理加以形成。但,使用於色變換層之材料係從 低的情況,對於採用濕處理的情況,完全地使色 光阻劑乾燥者爲困難。因此,如根據濕處理,乾 的水份乃從色變換層移動於有機EL層,於有機 產生稱作暗色區域之非發光缺陷之虞。因此,積 並非由濕處理而是經由乾處理型成色變換層者, 案有以下的技術。 部,和吸 光之螢光 光材料部 材料部的 光,實現 件部的發 度高之有 發光之有 換成綠色 由將含有 情況,使 能量線之 光材料部 鍍法之乾 耐熱性爲 變換層與 燥後殘留 EL層有 極地進行 例如,提 -6 - 201002123 對於專利文獻2係揭示有於基板上,具有彩色濾光片 層,螢光變換層(相當於色變換層),阻障層’電洞植入 電極,電子植入電極,於電極間,具有有關發光機能之有 機層,彩色濾光片層乃經由蒸鍍法而加以形成之有機EL 顯示裝置。在專利文獻2中,不只是彩色濾光片層,色變 換層亦由蒸鍍法(乾處理)而形成。此係因色變換層乃對 於水份弱,並控制上述暗色區域的產生者爲佳。在此,色 變換層由乾處理形成時,對於將成爲色變換層之基底的彩 色濾光片層或平坦化層,經由濕處理形成之情況,以高溫 完全地使此等乾燥之後,形成色變換層者爲佳。 在經由如此之乾處理之色變換層的形成,係可將色變 換層,於平坦化層的上方,對應於紅、綠、及藍的各副畫 素而選擇性地加以形成。從平坦化層及玻璃基板的折射率 乃對於約1 . 5而言,色變換層的折射率乃約2之情況,形 成色變換層的副畫素係比較於未形成色變換層之副畫素, 光的指向性爲低。例如,對於只於紅色的副畫素形成色變 換層之情況,對於綠色的副畫素及藍色的副畫素而言,紅 色的副畫素係光的指向性變低。 另外,對於複數種類形成色變換層之情況,因在各色 的色變換層間之折射率不同之故,在形成色變換層之副畫 素之間,亦產生關於光的指向性之差異。例如,對於於紅 色的副畫素及綠色的副畫素形成色變換層之情況,對於此 等副畫素間,一產生關於光的指向性之差異。 經由此等理由,對於從顯示器所射出之紅,綠,藍各 201002123 光,有產生各不同之指向性的可能性,經由對於顯示器之 視野角,係有畫面的發光色產生不同之虞。 然而,對於使來自副畫素的光取出量增大,係減少平 坦化層及/或玻璃基板的折射率之情況則爲重要。但,對 於減少平坦化層之折射率之情況,平坦化層等與色變換層 之間的折射率的差則變大。因此,在形成色變換層的副畫 素與未形成色變換層的副畫素之間,光的指向性的差則變 得更大,而有經由視野角,畫面之發色光則更產生不同之 虞。 有鑑於如此情事,作爲防止經由對於顯示器之視野角 的畫面發光色之變化的手段,揭示有以下的技術。 對於專利文獻3係揭示有於基板上,具有挾持於第1 電極及第2電極的發光機能層之畫素,和複數之上述畫素 所成單位畫素群;對於上述單位畫素群中被選擇之畫素, 設置散亂上述發光機能層之發光光線的散亂部之有機電激 發光裝置。 在專利文獻3所揭示之技術中,作爲只於藍色副畫素 及綠色副畫素之副畫素,設置經由凹凸之光擴散面,可防 止經由視野角之發色光的變化者。 [專利文獻1]日本特開2003-152897號公報 [專利文獻2]日本特開2001-196175號公報 [專利文獻3]日本特開2007-73219號公報 【發明內容】 201002123 [發明欲解決之課題] 但,在專利文獻3之上述凹凸係在藍色副畫素及綠色 副畫素,於相同尺寸設計下所形成之故,微調整在產生不 同光之副畫素間之光的指向性的差,無法以高的位準防止 經由視野角之發光色的變化者。 因而,檢討有對於經由視野角之發光色的變化之對策 。例如’嘗試使用於紅’綠’及藍之各色變換層之材料的 變更。但,使用於色變換層的材料變更係對於從色變換層 所射出的光的色純度及/或亮度有帶來不良影響之虞之故 ,而無法容易地進行。 因此,未進行色變換層材料的變更,而解決經由視野 角的發光色之變化者爲佳。經由視野角的發光色之變化係 如上述,因對於經由色變換層所射出的紅,綠,及藍的光 產生個不同之指向性而引起。具體而言,紅的指向性爲小 的另一方面’綠及藍的指向性爲大者則爲原因。因而,在 紅’與綠及藍之間,如可降低光的指向性的差,可解決上 述問題。 隨之’本發明之目的係提供,對於從色變換層產生的 各色光,未對於其色純度及亮度等帶來不良影響,降低在 各色的副晝素之光的指向性的差,未經由視野角而呈現不 同的發光色之有機EL顯示器。本發明之目的係提供該有 機EL顯示器之製造方法。 [爲解決課題之手段] -9- 201002123 本發明係關於具備基板、和含有平坦化層及至少一種 之色變換層的色變換濾光片部、和具有複數之發光部之有

<本發明之原理> 本發明者係經由目視有機電激發光顯示器的角度,對 於發光色產生變化的現象進行銳意檢討的結果,確定此現 象係因在不同色(R、G、B )之副畫素間,光的指向性不 同而引起者。因此,本發明者係完成由降低在此等副畫素 間之光的指向性的差者,可迴避如此現象的結論。 具體而言,在基板與彩色濾光片層或平坦化層之界面 部分之中,經由有機電激發光元件部的發光不所規定之副 畫素範圍,於各不同色之副畫素’形成不同密度之凹凸部 ’使從有機電激發光元件部所發光的R、G、B的光通過 -12- 201002123 於其凹凸部。由此,經由此,將在上述界面的 指向性,經由光的散亂原理,獨立地加以控制 色的光之指向性的差,可解決經由目視有機電 器的角度,發光色產生變化的問題。 然而’本發明者係對於經由該手法所做成 發光顯示器’將有機電激發光顯示器從正面或

〇 〇乃在後續之 各形成工程,爲了作爲反覆所成之各層的形成條件,對於 尺寸安定性優越者爲佳。更且,作爲透明基板100,使用 不會引起多色發光顯示器之發光性能下降的構成而爲重要 ,例如,可舉出玻璃,各種塑料,及各種薄膜等。 色變換濾光片部200係由於透明基板100之一方的面 上,形成爲條紋狀之紅色(R)、綠色(G)及藍色(B) 之各彩色濾光片層210R ' 210G、210B所成之彩色濾光片 層2

0之位置之透明電極 310,和形成於氣體阻障層250上,且呈包入透明電極 3 1 0地加以形成之有機電激發光層320,和形成於有機電 -14- 201002123 激發光層320上之反射電極330所構成。 (關於凹凸形狀) 在圖1所示的例中,選自各色之彩色濾光片層21 0R 、210G、210B的至少一色之彩色濾光片層(在圖1所示 的例中,係綠色濾光板層21 0G及藍色濾光板層21 0B)與 接合於此等之透明基板1〇〇的界面乃具有凹凸形狀。 綠色濾光板層210G與透明基板100之界面(界面1 )之凹凸形狀,及藍色濾光板層21 0B與透明基板100之 界面(界面2 )之凹凸形狀係作爲控制在入射外光的界面 之反射,可增強對於經由折射之有機電激發光元件部3 00 的入射外光量之形狀。另外,該凹凸形狀係作爲將來自有 機電激發光元件部300的出射光,可充分地散亂於畫像面 而射出之形狀。 界面1,2的凹凸形狀係將凹陷的平均深度作爲0.4〜 0.625//m。在此,凹陷的平均深度係指:在圖1之各彩色 濾光片層210(G、B)與透明基板100之各界面形狀,將 某凸部的紙面垂直方向位置與鄰接之凹部的紙面垂直方向 位置的差,在各彩色濾光片層210(G、B)之紙面水平方 向的全範圍,代表性地進行1處測量之平均値。該深度乃 0.525 〜0.625# m 者爲佳。 另外,界面1,2的凹凸形狀係將凹陷密度作爲〇. 8 3 〜1.99個/// m2。在此,凹凸密度係指在同圖之綠色濾光 板層210G及藍色濾光板層210B與透明基板1〇〇之界面 -15- 201002123 形狀(圖1之紙面水平方向X紙面垂直方向)之每1 μ m2 之凸部的個數。該凹凸密度乃0.83〜1.18個/ /zm2者爲佳 〇 更且’界面1 ’ 2的凹凸形狀係具有如此之凹陷的平

對於界面1,2之凹凸形狀的形成,首先,於對應於 彩色濾光片層210G,210B之圖案的透明基板1〇〇的面, 形成凹凸。接著,於該圖案上,層積所選擇之彩色濾光片 層 2 1 0G,2 1 0B。 作爲於透明基板1 〇 〇形成凹凸的方法,係可使用一般 使用表面的粗面化處理之方法,例如,將光阻劑圖案使用 餘光罩,經由化學藥劑,電漿等而進行蝕刻之方法。另外 ,亦可使用利用光罩與硏磨劑,削去表面,例如使用噴砂 法,櫛齒而刷除表面之機械性的方法等。 作爲透明基板1 00而使用玻璃基板的情況,經由噴砂 法,使用平均粒徑爲5" m的硏磨材,經由進行2〜8秒, 理想爲3~7·5秒處理之時,可將最佳的凹凸形成於玻璃基 板面。由不過度地加長處理時間,可控制凹凸形狀之凹凸 密度成爲過大,防止損及處理表面的亮度者。 -17- 201002123 然而,在圖1所示的例中,紅色濾光片層210R與透 明基板1〇〇之界面,係未附上凹凸形狀。對於紅色濾光片 層210R’係於透明基板1〇〇上,可經由公知的各種方法 而加以層積。例如,將公知的紅色濾光片材料,經由旋塗 法而進行塗布,可根據經由微光影法而進行圖案化之時而 加以形成。 (關於有機電激發光顯示器之構成要素) 以下,在圖1所示之有機電激發光顯示器之各構成要 素之中’對於上述之基板1 0

Description of the Invention: [Technical Field of the Invention] The present invention relates to an organic electroluminescence display (hereinafter also referred to as "organic EL display"). More specifically, the organic EL display of the present invention is an organic EL display which emits light from the organic EL element portion and which does not pass through the viewing angle to exhibit different color light. The present invention relates to a method of manufacturing an organic EL display as such. [Prior Art] Currently, display devices such as liquid crystal displays and organic EL displays are used as display units of electronic devices such as mobile phones, personal computers, digital photocopiers, and printers. The light-emitting form of the display device described above is a self-luminous type and a non-emitted type. The self-luminous type is suitable for an electroluminescence element (EL element), a field emission display (FED), and a cathode ray tube (CRT). In contrast, the non-light-emitting type is used for a liquid crystal display element or the like. Further, the color display method of the display device described above is a colorful mode or a full color mode in which three primary colors of red, green, and blue are illuminated. In these methods, a color filter layer is often used to intervene between the light-emitting surface of the light-emitting element and the image surface. According to this means, the specific wavelength from the light-emitting element can be selectively emitted, the color purity of the three primary colors can be increased, and the image can be displayed as high quality. Among the display devices as described above, in particular, for the organic EL display, the following techniques have been proposed. -5-201002123 Patent Document 1 discloses an organic EL element portion having a fluorescent material in a fluorescent material portion having visible light emitted from an organic EL material portion. This element is a color conversion filter provided with a fluorescent material, and absorbs the fluorescent light in the visible light field in the organic EL light-emitting portion. In the technique disclosed in Patent Document 1, the organic EL element light color is not limited to white. Therefore, in comparison with the related art, the bright EL element portion can be applied to a light source. For example, the color of the blue light can be changed to light or red by using a color conversion method using the blue EL element portion. In recent years, the fluorescent material portion having the fluorescent material dye disclosed in Patent Document 1 has been highly developed as a weak color conversion method for the wavelength range of the near-ultraviolet light visible light of the illuminating body. . The color conversion layer (corresponding to the fluorescene) used in the color conversion method can be mainly formed by wet treatment via a photoresist or by steam treatment. However, the material used for the color conversion layer is low, and in the case of wet treatment, it is difficult to completely dry the color photoresist. Therefore, as in the case of the wet treatment, the dry moisture moves from the color conversion layer to the organic EL layer, and organically produces a non-luminous defect called a dark region. Therefore, the product is not a wet process but a dry process type color conversion layer, and the following techniques are known. And the light of the material part of the light-emitting fluorescent material part is changed to have a high degree of light emission in the part, and the green heat is changed by the plating method to make the dry heat resistance of the light material part of the energy ray. The layer and the post-drying residual EL layer are extremely subjected to, for example, -6 - 201002123. Patent Document 2 discloses that a color filter layer, a fluorescent conversion layer (corresponding to a color conversion layer), and a barrier layer are provided on a substrate. A hole-embedded electrode, an electron-implanted electrode, an organic layer having an organic light-emitting function between the electrodes, and a color filter layer formed by an evaporation method. In Patent Document 2, not only the color filter layer but also the color conversion layer is formed by a vapor deposition method (dry process). It is preferable that the color conversion layer is weak for moisture and controls the generation of the above dark region. Here, when the color conversion layer is formed by dry processing, the color filter layer or the planarization layer which is the base of the color conversion layer is formed by a wet process, and after drying at a high temperature, the color is formed. It is better to change the layer. In the formation of the color conversion layer thus processed, the color conversion layer can be selectively formed above the planarization layer corresponding to each of the sub-pixels of red, green, and blue. The refractive index of the flattening layer and the glass substrate is about 1.5, and the refractive index of the color conversion layer is about 2, and the sub-picture forming the color conversion layer is compared with the sub-picture without the color conversion layer. The directivity of light is low. For example, in the case where the color conversion layer is formed only by the red sub-pixel, the directivity of the red sub-pixel element light is low for the green sub-pixel and the blue sub-pixel. Further, in the case where a plurality of types of color conversion layers are formed, since the refractive indices between the color conversion layers of the respective colors are different, a difference in directivity with respect to light occurs between the sub-pixels forming the color conversion layer. For example, in the case where the red sub-pixel and the green sub-pixel form a color conversion layer, a difference in directivity with respect to light is generated between the sub-pixels. For these reasons, the red, green, and blue 201002123 light emitted from the display may have different directivity, and the illuminating color of the screen may be different depending on the viewing angle of the display. However, it is important to increase the amount of light extracted from the sub-pixels to reduce the refractive index of the flattened layer and/or the glass substrate. However, in the case where the refractive index of the planarization layer is reduced, the difference in refractive index between the planarization layer and the like and the color conversion layer becomes large. Therefore, the difference in directivity of light between the sub-pixel forming the color conversion layer and the sub-pixel without the color conversion layer becomes larger, and the color of the light of the picture is different through the viewing angle. After that. In view of such circumstances, the following technique has been disclosed as means for preventing a change in the illuminating color of the screen through the viewing angle of the display. Patent Document 3 discloses a pixel having a light-emitting function layer held on a first electrode and a second electrode on a substrate, and a plurality of pixels of the pixel set in the above-mentioned unit pixel group; The selected pixel is provided with an organic electroluminescence device that disperses the scattered portion of the illuminating light of the illuminating functional layer. According to the technique disclosed in Patent Document 3, as a sub-pixel of only the blue sub-pixel and the green sub-pixel, a light diffusing surface passing through the unevenness is provided, and a change in the color light passing through the viewing angle can be prevented. [Patent Document 1] Japanese Laid-Open Patent Publication No. 2001-196175 (Patent Document 3) Japanese Laid-Open Patent Publication No. JP-A No. Hei. No. 2007-73219. However, in the above-mentioned embossing of Patent Document 3, the blue sub-pixel and the green sub-pixel are formed under the same size design, and the directivity of the light between the sub-pixels of different light is finely adjusted. Poor, it is impossible to prevent a change in the illuminating color through the viewing angle at a high level. Therefore, there is a review for countermeasures against changes in the illuminating color through the viewing angle. For example, 'trying to change the materials used in the red 'green' and blue color conversion layers. However, the material change used in the color conversion layer has an adverse effect on the color purity and/or brightness of the light emitted from the color conversion layer, and cannot be easily performed. Therefore, it is preferable to change the color of the color conversion layer without changing the color of the color conversion layer. The change in the illuminating color via the viewing angle is caused by the fact that the red, green, and blue light emitted through the color conversion layer are different in directivity as described above. Specifically, the directivity of red is small. On the other hand, the directivity of green and blue is large. Therefore, the above problem can be solved between red' and green and blue, such as to reduce the difference in directivity of light. Accordingly, it is an object of the present invention to provide that each color light generated from a color conversion layer does not adversely affect its color purity, brightness, and the like, and the difference in directivity of light of each color is reduced. An organic EL display exhibiting different illuminating colors at a viewing angle. SUMMARY OF THE INVENTION An object of the present invention is to provide a method of manufacturing the organic EL display.

In such an organic electroluminescent display, at least one of the color filter layers can be interposed between the substrate and the planarization layer. In this case, the interface between the substrate and the color filter layer has a concavo-convex shape, and the concavo-convex shape has a different concavo-convex density for each of the sub-pixels. In the organic electroluminescence display, the uneven shape may be a shape in which a plurality of concave portions and convex portions having a smaller period than the sub-pixel width are provided. Further, the uneven shape may be a shape having a different cycle shape for each of the sub-pixels'. -10-201002123 The present invention includes an art for forming a color-converting calender sheet portion including a color conversion layer having a reduced planarization on a substrate, and an organic conversion filter portion for forming a plurality of organic light-emitting portions. The optical element unit is configured to form a method for producing an organic electroluminescence display device of a multi-pixel by the plurality of light-emitting portions, and to form an uneven shape on the surface of the substrate that is in contact with the substrate, and to form the uneven shape as the sub-picture A method of manufacturing an organic electric actuator that is adjusted to different uneven density. Further, the present invention relates to a color conversion filter portion including a color conversion layer having a reduced planarization on a substrate, and a first layer of the layer is formed, and an organic light element portion having a plurality of light-emitting portions is formed on the substrate. 'The construction of the second layered body and the process of bonding the above-mentioned first integrated body and the second laminated body; and the manufacture of the organic electroluminescent display through the plural 'predetermined plural sub-pixels' The substrate surface in contact with the flat layer is formed into a concavo-convex shape, and the convex shape is adjusted to each of the sub-pixels to a method of manufacturing a different uneven density electroluminescent display. In such a method of fabricating an organic electroluminescent display, at least one of the color filters may be formed between the board and the planarization layer. In this case, a concave-convex shape is formed on the surface of the color filter layer contact plate, and the uneven shape is adjusted to a different unevenness density for each of the precursors. In the organic electroluminescent display, the concavo-convex shape can be adjusted to at least one period, a plurality of layers having a smaller sub-pixel width, and a sub-flat layer having the electric excitation number, and each of the light-display layers and the integrated body.

Further, the uneven shape may be adjusted to be different for each of the sub-pixels. [Effect of the Invention] The organic electroluminescence display of the present invention is a sub-pixel specified by the light-emitting portion of the organic electroluminescence element unit, and the substrate surface is made of a specific shape. Between the pixels, the directivity of the light is finely adjusted, and the change of the illuminating color through the viewing angle is prevented at a high level. [Embodiment] Hereinafter, the principle of the present invention and the organic electroluminescent display of the present invention and The manufacturing method will be described. <Principle of the Invention> The present inventors determined the phenomenon of the change in the luminescent color by visually observing the angle of the organic electroluminescent display, and determined that the phenomenon is due to different colors (R, G, B). Among the sub-pictures, the directivity of light is different. Therefore, the inventors have concluded that the difference in the directivity of the light between the sub-pixels can be avoided. Specifically, in the interface portion between the substrate and the color filter layer or the planarization layer, the sub-pixel range defined by the light emission of the organic electroluminescence element portion is not formed by the sub-pixels of the different colors. The uneven portions of different densities pass the light of R, G, and B emitted from the organic electroluminescence element portion to the uneven portion of -12-201002123. As a result, the directivity of the interface is independently controlled by the directivity principle of the light, and the difference in the directivity of the light is controlled, and the problem that the luminescent color changes due to the angle of the visual organic device can be solved. However, the inventors of the present invention measured the angular distribution of the luminescence spectrum while the organic electroluminescence display was viewed from the front or the side of the illuminating display made by the method. The difference in the directivity difference between the lights of the respective colors is at the same time as the performance of the organic electroluminescent device portion of the color is maintained. <Organic electroluminescent display and method of manufacturing the same> [Organic electroluminescent display (Form 1)] Hereinafter, an embodiment of the present invention will be described in detail with reference to Fig. 1 . However, the following examples are illustrative of a single embodiment of the invention comprising a color filter layer, as may be suitable for the industry, i.e., for examples that do not contain a color filter layer, as explained. (Configuration of the whole) The organic electroluminescence display of the present invention (the color conversion filter unit 200 which is laminated on the transparent substrate 100 by the transparent substrate 100 as shown in the bottom emission type, and the color conversion filter unit) In the surface, the organic electroluminescence element unit 300 is changed to the light of the color filter unit 200 and the organic electroluminescence element unit 3 00', and the result of the organic electro-slanting surface of each excitation light is lowered. The details of the degree of completion and brightness are also described in detail, but only for design changes. The following description is based on the light entering the surface of one of the faces of Figure 1, and the color change and the external air are interrupted-13-201002123 (not The seal material shown in the figure). The transparent substrate 100 is a layer having respective constituent elements of the electromechanical excitation light display formed in order to support them. The transparent substrate 100 is made of a color filter layer 210 (R, G, B), a light shielding layer 220, and a red conversion layer 240 to be described later, and an organic electroluminescence element portion 3, which are resistant to light transmittance. 00 (electrode, organic light-emitting layer, etc.) conditions (solvent, temperature, etc.). Further, the transparent substrate 1 is formed in the subsequent processes, and it is preferable that the dimensional stability is superior in order to form the respective layers formed as the reverse. Further, as the transparent substrate 100, it is important to use a configuration that does not cause a decrease in the light-emitting performance of the multi-color light-emitting display, and examples thereof include glass, various plastics, and various films. The color conversion filter unit 200 is formed of stripe-shaped red (R), green (G), and blue (B) color filter layers 210R' 210G, 210B on one surface of the transparent substrate 100. The formed color filter layer 210, and the light shielding layer 220' embedded in the gap between the color filter layers, and the planarization layer 230 formed above the color filter layer 210 and the light shielding layer 220, And a red conversion layer 240 formed on the planarization layer 230 and formed at a position corresponding to the red (R) color filter layer 210R, and formed on the planarization layer 230 by encapsulating the red conversion layer 240 The gas barrier layer is composed of 250. The organic electroluminescent device unit 300 is formed on the gas barrier layer 250, formed on the transparent electrode 310 corresponding to the position of the color filter layer 210, and formed on the gas barrier layer 250. The organic electroluminescence layer 320 formed by encapsulating the transparent electrode 310 and the reflective electrode 330 formed on the organic light-14-201002123 excitation layer 320 are formed. (About the uneven shape) In the example shown in FIG. 1, a color filter layer of at least one color selected from the color filter layers 21 0R , 210G , and 210B of the respective colors (in the example shown in FIG. 1 , is green) The interface between the filter layer 21 0G and the blue filter layer 21 0B) and the transparent substrate 1 接合 bonded thereto has an uneven shape. The uneven shape of the interface (interface 1) between the green filter layer 210G and the transparent substrate 100, and the uneven shape of the interface (interface 2) between the blue filter layer 210B and the transparent substrate 100 are controlled as an interface at the incident external light. The reflection enhances the shape of the incident external light amount to the organic electroluminescence element portion 300 passing through the refraction. In addition, the uneven shape is a shape in which the emitted light from the electro-optic excitation light element unit 300 can be sufficiently scattered on the image surface. The uneven shape of the interfaces 1, 2 is such that the average depth of the depressions is 0.4 to 0.625 / / m. Here, the average depth of the depressions refers to the interface shape of each of the color filter layers 210 (G, B) and the transparent substrate 100 of FIG. 1, and the vertical direction of the paper surface of a certain convex portion and the paper surface of the adjacent concave portion. The difference in the position in the vertical direction is representatively measured as the average value of one measurement in the entire range of the horizontal direction of the paper surface of each of the color filter layers 210 (G, B). The depth is preferably 0.525 to 0.625# m. Further, the uneven shape of the interfaces 1, 2 is such that the density of the depressions is 〇 8 3 to 1.99 / / / m 2 . Here, the uneven density refers to the shape of the interface -15-201002123 between the green filter layer 210G and the blue filter layer 210B of the same figure and the transparent substrate 1 (the horizontal direction of the paper in the horizontal direction of the paper X in FIG. 1). The number of protrusions of 1 μ m2. The uneven density is preferably 0.83 to 1.18 / /zm 2 and the unevenness of the interface 1 ' 2 has an uneven depth and a concave-convex density as such a regular or irregular shape. By not excessively increasing the average depth of the recesses and the unevenness density, it is possible to control the disordered reflection of the incident external light to be excessively large, and to prevent the luminance loss of the light-emitting surface. Such a concavo-convex shape is attached to each of the sub-pixels (in the example shown in Fig. 1 'each of the green filter layer 210G and the blue filter layer 210B), and has a different uneven density. This is because the directionality of the light using the principle of the scattering can be made high to prevent the change of the illuminating color through the viewing angle. Specifically, the uneven shape is defined by a period of 1⁄2 or more of the wavelength of the changed light, whereby the unevenness density is adjusted, and the refractive index is adjusted to be emitted from each of the sub-pixels for each sub-pixel. The directivity of the light. Here, the period of the uneven shape refers to the horizontal distance of the finger surface between the adjacent convex portions of the respective color filter layers 2 1 0 (G, B) in the example shown in Fig. 1 . For example, in the case where the uneven density of the uneven shape of the interface 1 is 0.83 to 0.91 m2, it is preferable that the uneven density of the uneven shape of the interface 2 is 1.01 to 1.18 / " m2. In this way, when the unevenness density is finely adjusted between the sub-pixels, the difference in the directivity of the light between the sub-pixels can be reduced, and the difference in the luminescent color via the viewing angle can be sufficiently prevented. In the case shown in FIG. 1, in the pixel (the whole of FIG. 1), the portion corresponding to the light-emitting portion of the organic electroluminescence element portion - 16102102123, that is, the transparent electrode 3 is provided. The width of the 1 0 part. However, although the interface between the red color filter layer 21 OR and the transparent substrate 100 shown in FIG. 1 is not completely covered with irregularities, in the present invention, the unevenness density at the interface is described as the flaw, and the interface is also included. Each sub-pixel has a different density of concave and convex. As a specific example of such a concavo-convex shape, it is possible to have a configuration of a concave portion and a convex portion having at least one cycle and a smaller sub-pixel width. Further, as a specific means for making the unevenness density of the unevenness of the interfaces 1, 2 different, it is possible to attach a concave-convex shape of a different period to each sub-pixel (each interface 1, 2). For the formation of the uneven shape of the interfaces 1, 2, first, irregularities are formed on the surface of the transparent substrate 1A corresponding to the pattern of the color filter layers 210G, 210B. Next, on the pattern, the selected color filter layers 2 1 0G, 2 1 0B are stacked. As a method of forming the unevenness on the transparent substrate 1 , a method of roughening the surface of a general surface can be used, for example, a method of etching a photoresist pattern using a mask, via a chemical, a plasma, or the like. . Further, it is also possible to use a mask and a honing agent to remove the surface, for example, a sandblasting method, a method of rubbing the teeth, and a mechanical method of removing the surface. When a glass substrate is used as the transparent substrate 100, a honing material having an average particle diameter of 5 " m is used by a sand blasting method, and when it is treated for 2 to 8 seconds, preferably 3 to 7·5 seconds, The optimum concavities and convexities are formed on the surface of the glass substrate. By not excessively lengthening the processing time, it is possible to control the unevenness of the unevenness of the uneven shape to prevent the brightness of the treated surface from being damaged. -17- 201002123 However, in the example shown in Fig. 1, the interface between the red color filter layer 210R and the transparent substrate 1 is not attached with a concavo-convex shape. The red color filter layer 210R' is attached to the transparent substrate 1A, and can be laminated by various known methods. For example, a known red filter material is applied by a spin coating method, and can be formed by patterning by a micro-gloss method. (Components of the organic electroluminescence display) Hereinafter, among the constituent elements of the organic electroluminescence display shown in Fig. 1, elements other than the above-described substrate 100 will be described in detail. Color filter layer 210 The color filter layer 210 is a layer that is incident on the incident light of the layer and is lifted by a specific wavelength in order to obtain the color purity of light having a certain range of wavelengths. The color filter layer 210 (R, G, B) on the transparent substrate 100 can be formed using a material for a flat panel display. The color filter layer 210 can be used as a blue filter layer that transmits a wavelength of 400 to 550 nm, a green filter layer that transmits a wavelength of 500 to 600 nm, and a red filter that transmits a wavelength of 600 nm or more. The structure of the slice. These color filter layers are formed of a photosensitive resin layer which is preferably a dye or a pigment, which is preferably a pigment dispersed. As a dispersion pigment, an azo color system, an insoluble gas system, a condensed azo system, and the like are preferably used. Indigo cyanine, quinolin [I fluorenone-18-201002123, dioxazine, isoindolinone, anthraquinone, thioindole, dinaphthene benzene] and these mixed systems. The color filter layer 210 has a stripe pattern formed by repeating red (R), green (G), and blue (B), and each pattern has a pattern width of 60 to 100 /zm, and is 70 to 90/zm. The pattern is spaced apart on one of the faces of the transparent substrate 1〇〇. As the method of forming the color filter layer 210, a coating method can be used, and it is particularly preferable to use a light treatment. The light-shielding layer 220 is formed by the purpose of improving the contrast by not transmitting the visible region to each of the color filter layers. The light shielding layer 220 is formed using a material for a general flat panel display. As a method of forming the light shielding layer 220, a coating method can be used, and in particular, a light treatment is preferred. The planarization layer 203 is formed by the purpose of protecting the color filter layer 210 (R, G, B). In addition, the flattening layer 230 is formed so as not to affect the dimensional accuracy of each layer above the layers 210 and 220 in order to be a step generated by the color filter layer 210 and the light shielding layer 220. Floor. Therefore, the flattening layer 203 is required to be rich in light transmittance, and is formed by selecting a material and a process which do not deteriorate the color filter layer 210 (R, G, B). As a material which can be applied to the planarization layer 203, light-hardening or -19-201002123 photothermal curing resin is light- and/or heat-treated, and the atomic species 'ion species are generated to be polymerized or cross-linked'. The composition as insoluble and non-melting is general. Further, in order to perform patterning, the photocurable or photothermal curing resin is preferably one which is soluble in an organic solvent or an alkaline solution before curing. Specifically, 'as a photocurable or photothermal curing resin, (1) an acrylic polyfunctional monomer or oligomer having a plurality of acrylonitrile groups, isobutylene groups, and light or thermal polymerization a film formed of a starting agent, which is subjected to light or heat treatment to cause photopolymerization or thermal radical generation to be polymerized, and (2) a composition of polyethylene cinnamic acid ester and a sensitizer, which is subjected to light or heat treatment. (3) a film of a composition of a chain or a cyclic olefin and a bisazide, which is produced by light or heat treatment, and a olefin is crosslinked, and (4) will have A film of a composition of a monomer of an epoxy group and a photooxygen generator is produced by light or heat treatment to generate oxygen (cation). In particular, in the case of using the photocurable or photothermal curing resin of the above (1), it can be patterned by light treatment, and is excellent in reliability in terms of solvent resistance and heat resistance. Examples of other photocurable or photothermal curing resins include polycarbonate (PC), polyethylene terephthalate (PET), polyether oxime, polyvinyl butyral, and polyphenylene. Ether, polyamine, polyetherimide, norbornane resin, isobutylene resin, isobutylene maleic anhydride copolymer resin, thermoplastic resin such as ring-20-201002123 olefin, epoxy resin, ethyl phenol resin Resin, acrylic resin, ethyl acrylate resin, imine ethyl formate resin, urea resin, melamine [formaldehyde] tree thermosetting resin, or contain polystyrene, polypropylene, polycarbonate functional 'or 4-functional The polymer of the alkoxy decane is mixed as the method of forming the planarization layer 230, and it is preferable to use a coating method using a light treatment. However, Fig. 1 is an example in which the color filter layer 210 is included, and in the case where the color filter layer 210 is entirely contained, an uneven shape is formed at the interface of the transparent substrate 1 2 layer 203. In this case, it is also possible to use a cloth method, especially a light processor. Red conversion layer 240 The color conversion layer is a sensory pigment that disperses the fluorescent pigment in a near-ultraviolet range or a visible range, absorbs the fluorescent pigment, and has a fluorescent light-emitting function that reflects the visible range of the wavelength of the incident light. Made of layers. In the example shown in Fig. 1, only the red conversion layer 240 is used among the red conversion layer, the green layer, and the blue conversion layer. The fluorescent pigment in the blue-green-green range that absorbs the light emitted by the organic electroluminescence device unit 300 is used as a fluorescent pigment for the layer 240 of the fluorescent light in the red range, and examples thereof include Rhodamine B and 6G. Rhodamine 3B, Rhodamine 101, Rhodamine 10, Sulfhydrazine, Basic Rhodopsin 1 1 , Basic Red 2, etc. Rhodamine pigment, Phthalocyanine, 1-ethyl-2-[4 -(p-dimethylaminophenyl)-1,3-butadiene, amine methyl ester, amine lipid, etc., and the like. Especially in the case of unfinished and flat use, the color of the tree is changed, and even the color of red is changed to danming, the color of the pigment, the color of the pigment, the stagnation of the stagnation, the stagnation of the sputum, the sputum Steep pigments and chewable pigments. Further, various dyes such as direct dyes, acid dyes, basic dyes, disperse dyes and the like can also be used in the form of fluorescence. Although it is not used in the example shown in FIG. 1, it is used for absorbing the blue or even cyan-range light emitted by the organic electroluminescence device unit 300, and is used for fluorescing the green-converted layer of the fluorescent light in the green range. Examples of the coloring matter include 3-(2'-benzothiazole)-7-dimethylaminocoumarin (coumarin 6) and 3-(2'-benzimidazole)-7-dimethyl group. Aminocoumarin (coumarin 7 ), 3-(2'-N-benzimidazole)-7-dimethylaminocoumarin (coumarin 30), 2,3,5,6-111, 411-tetrahydro-8-trifluoromethylquinazine (9,93,1-811) Coumarin dyes such as coumarin (coumarin 153) and coumarin dyes such as basic yellow 51 , ophthalmide pigments such as Solvent Yellow 11, Solvent Yellow 116, and the like. Further, various dyes such as direct dyes, acid dyes, basic dyes, and disperse dyes can also be used in the form of fluorescence. The blue conversion layer is generally abbreviated to have a wavelength range which is slightly the same as the wavelength range of the light which is selected to be emitted by the organic electroluminescence element unit 300 in the blue color filter layer 210B, and is not normally omitted in the example shown in FIG. use. However, instead of omitting the blue conversion layer, a transparent photosensitive resin layer can be formed as a mold. The color conversion layer (in the example shown in Fig. 1 , the red conversion layer 240) can be formed by various dry processes, and it is preferable to form it by a vacuum vapor deposition method without forming an organic material. As the heating method of the vacuum evaporation method, either a direct heating method or an indirect heating method may be used, and in particular, resistance heating, electron beam heating, or infrared heating may be used -22-201002123. In the case where a plurality of color conversion dyes are used to form a color conversion layer, a preliminary mixture of a plurality of color conversion dyes is mixed in a predetermined ratio, and a preliminary mixture can be used for co-evaporation. Further, a plurality of color conversion dyes may be disposed in individual heating portions, and the respective color conversion pigments may be individually heated to perform co-evaporation. In particular, in the case where a plurality of kinds of color conversion dyes have large differences in characteristics such as vapor deposition rate and/or vapor pressure, it is advantageous to use the latter method. The thickness of the color conversion layer (in the example shown in FIG. 1 , the red conversion layer 240 ) is preferably 1/m or less, and is preferably at a point where the function of the color conversion layer can be exhibited, and 200 nm to 1 nm. The zm is better at the point where the color conversion layer can be effectively utilized. Gas barrier layer 250 The gas barrier layer 25 is a layer formed to prevent intrusion of moisture and/or oxygen from the outside to the color conversion layer (in the case of the same figure, the red conversion layer 240). This color change pigment is an organic matter 'weakness to moisture'. Here, the purpose of the stroke of the gas barrier layer 25 is the protection of the red conversion layer 240. However, in the example shown in FIG. 1, not only the red conversion layer 240 but also the planarization layer 230 is protected. However, this configuration is also effective for protecting the organic electroluminescent layer 320 to be described later in order to prevent leakage of moisture from the color conversion filter unit 200. As a material which can be applied to the gas barrier layer 250, it is possible to use a material having electrical insultability and having a high transparency for the gas and the organic solvent 1 and having a high transparency in the visible region of the -23-201002123 (The transmittance in the range of 400 to 7 〇〇 nm is 50% or more). Further, the hardness formed on the gas barrier layer 250 to withstand the formation of the transparent electrode 310 or the like described later is preferably a material having a film hardness (pencil hardness) of 2H or more. However, this film hardness (pencil hardness) is based on the standard of JIS K5600-5-4. As the specific gas barrier layer 250, for example, an inorganic oxide such as SiOx, SiNx, SiNxOy, AlOx, TiOx, TaOx or ZnOx, or an inorganic nitride or the like can be used. The method for forming the gas barrier layer 250 is not particularly limited, and a sputtering method, a CVD method, a vacuum deposition method, or the like can be used. Further, the gas barrier layer 250 is of course a single layer, and may be a laminate of a plurality of layers. The color conversion filter portion 200 is formed on the transparent substrate 1A as described above. Transparent Electrode 3 1 0 As a material applicable to a transparent electrode, ITO, tin oxide, indium oxide, IZO, zinc oxide, zinc-aluminum oxide, zinc-gallium oxide, or for such oxides can be used. A conductive transparent metal oxide of a dopant such as F or Sb is added. Further, the transparent electrode 310 is formed by a vapor deposition method, a sputtering method or a chemical vapor deposition method (CVD), and can be obtained by patterning using a photolithography method or the like. Among such formations, in particular, sputtering is preferred. The transparent electrode 3 1 0 can also be used as either an anode or a cathode. For the case where the transparent electrode 310 is used as a cathode, a cathode buffer layer (not shown) is formed between the transparent electrode-24-201002123 310 and the organic electroluminescent layer 320, and the organic electroluminescent layer 3 is lifted.

As a material applicable to the cathode buffer layer, an alkali metal such as Li, Na, K or Cs, an alkaline earth metal such as Ba or Sr, an alloy containing such a metal, a rare earth metal, or a fluorine of such a metal can be used. Compounds and the like. The film thickness of the cathode buffer layer is preferably 1 Onm or less from the viewpoint of ensuring transparency. On the other hand, in the case where the transparent electrode 3 10 is used as an anode, a layer of a conductive transparent metal oxide is provided between the transparent electrode 310 and the organic electroluminescent layer 320 to enhance the organic electroluminescence. The hole implantation efficiency of layer 320 is good. As a material suitable for the conductive transparent electrode, ITO, tin oxide, indium oxide, IZO, zinc oxide, zinc-aluminum oxide, zinc-gallium oxide may be used, or for these oxides, F or The material of the dopant such as Sb.

A material of each layer of 320 may be a known constituent. Further, each layer constituting the organic electroluminescent layer 320 is formed. It can be formed by any method known in the art of steaming or the like. For the case where the red conversion layer 240 shown in Fig. 1 is used, the organic electroluminescence layer 30 is realized from blue to blue. A green illuminator is important. As a material which can be applied to an organic light-emitting layer which emits light from blue to cyan, for example, a benzothiazole-based, benzimidazole-based or benzoxazole-based system can be used. Fluorescent whitening agent, metal chelated oxynium cation compound, styryl benzene compound, or aromatic methine compound, etc. Further, in the example shown in Fig. 1, the luminescence of the organic light-emitting layer is necessary It can also be used as white light. However, it is important to use a well-known red dopant in this case. This is not shown in Fig. 1, but the case of using a green conversion layer as a color conversion layer The luminescence of the layer is important as a luminescence from blue to red. The reflective electrode 3 3 0 -26- 201002123 As a material applicable to the reflective electrode 330, a high reflectivity metal is used, and a high reflectance is not used. A shape alloy, or a highly crystalline microcrystalline alloy is preferable. Examples of the metal having high reflectance include A1, Ag, Mo, W, Ni, or Cr. As an amorphous alloy having high reflectance, For example, NiP, NiB, CrP, or CrB may be mentioned. Examples of the high-reflectivity microcrystalline alloy include NiAl. The reflective electrode 3 30 may be used as either an anode or a cathode. When the cathode is used as a cathode, a cathode buffer layer (not shown) is formed between the reflective electrode 310 and the organic electroluminescent layer 2020 to enhance the electron implantation efficiency for the electromechanical excitation layer 3 20 . It is better. Alternatively, for a metal having a high reflectance characteristic as described above, an amorphous alloy or a microcrystalline alloy, a material having a small function, that is, an alkali metal such as lithium, sodium or potassium, or calcium, magnesium or strontium is added. It is alloyed with an alkaline earth metal to improve the efficiency of electron implantation.

The resulting reflective electrode 330. In the example shown in Fig. 1, the reflective electrode 330 has a stripe pattern intersecting the pattern of the transparent film, and the intersecting range is a sub-pixel. However, as described above, the obtained organic electroluminescence light shows a dry nitrogen environment (the environment in which the concentration of 〇2 and the concentration of H20 is 10 ppm or less) in the glove box, and is formed by using a sealing glass and a chemical adhesive (not shown).

Prepare 200mm><200 mm x 0.7 mm glass substrate. First, a Cr film (film thickness l 〇〇 nm) formed by patterning is used as a mask at a specific pitch, and a dry etching method (C4F8: 16 ms CCm, CH 2 F 2 : 16 sccm, pressure 0.8 Pa, and power 2 kW) is used. The blue sub-pixel region and the green sub-pixel region on the color filter layer side of the substrate are formed at a depth of 0.6 " m, and a straight conical concave and convex substrate having a pitch of 0.2 // m is 100° on the substrate 1 On the other hand, the coating liquid for a light-shielding layer (CK8400L Fujifilm ARCH) was applied by spin coating, and dried at 80 ° C. Thereafter, a pattern of a sub-pixel size (300/zm in the longitudinal direction of 300/zm in the lateral direction and 1 μm in the thickness direction) was formed by a photolithography method at a pitch of 3 3 Ο μm, and the light-shielding layer 220 was laminated on the substrate 100. For the formation of the blue color filter 210B, a blue color filter material (Fuji soft film ARCH system: color mosaic CB-70 0 1 ) is applied to the substrate 1 by spin coating [implementation via photolithography] The pattern of the law. Specifically, a substrate 100 formed in a straight conical shape having a depth of 0.6 #m and a pitch of 0.2/zm is drawn. Thus, the substrate side of the blue color filter 210B is obtained in a region having a depth of 0.6 vm, a pitch of 〇. 2 // m, an average density of 0.88 / " m2, and a concave and concave area size 80 "m><300 ym, a line pattern having a film thickness of 2 em. For the formation of the green color filter 210G, a green color filter material (Fuji Film ARCH-37-201002123: Color Mosaic CG-7001) is applied onto the substrate 1 by spin coating, and light lithography is performed.

On the other hand, in Comparative Example 1 in which the interface between the substrate 1 and the blue and green filters 21 0B and 2 10G was not used as the uneven density, it was confirmed that the change in the luminescent color of the screen via the observation angle was remarkable. Further, in Comparative Example 2 in which the interface between the substrate 100 and the blue and green filters 210B, 2 10G was the same unevenness density, the change in the luminescent color of the screen through the observation angle was determined. Incidentally, no change was observed for the luminance and chromaticity of Examples 1, 2 and Comparative Examples 1, 2. Accordingly, in the organic electroluminescence display of the first and second embodiments, it is determined that the interface between the substrate and the color filter has a structure for adjusting the unevenness density of each of R, G, and B, while maintaining brightness and chromaticity. The difference in directivity of light between R, G, and B can be reduced. However, the above results are suitable for adjusting the interface between the substrate and the color filter. However, in the case where the color filter is not present, it is expected that an example in which the interface between the substrate and the planarization layer is appropriately adjusted can be obtained. result. [Industrial Applicability] In the present invention, the interface between the substrate and the color filter or the planarization layer is a specific shape, and the difference in directivity of the light is finely adjusted between the sub-pixels of the different colors, which can be high. The level prevents the change of the illuminating color through the viewing angle. The present invention is promising in that it is possible to provide various electronic devices such as a mobile phone having a display unit that does not have a change in the illuminating color of the viewing angle, as in the case of -39-201002123.
