1283379 九、發明說明: 【發明所屬之技術領域】 本發明係有關於一種四色全彩化有機電激發光 . 顯示裝置及其製作方法,不僅可有效提高各色光源之穿透 率及色彩飽和度,又可降低耗電量及提高生產良率者。 【先前技術】 # 近年來進行有機電激發光顯示裝置(OLED)相關的研 究及發展,如何達到具有全彩顯示效果的技術往往是該有 機電激發顯示裝置發展成功與否的關鍵,其達到全彩顯示 功能之最常見的製作方法有以下兩種: 1. 分別將可產生紅(R)、綠(G)、藍(B)三原色之有機電激發 光元件獨立設置(Side by Side),並將此三種色光以適當 比例混合搭配而產生全彩的顯示效果。然而,在製作過 程當中,由於紅、綠、藍三種發光材料必須分開蒸鍍。 • 每個像素的遮罩開口僅僅只有十微米,因此將會提高遮 罩對位時的困難度。 2. 設置有至少一可產生白色光源之有機電激發光元件,搭 配使用技術純熟之彩色濾光片。藉由彩色濾光片的使用 以達到過濾白色光源之目的,並因此產生全彩的顯示效 果。該設置方法與紅、綠、藍發光材料分開蒸鍍的方式 相較之下較為簡潔。然而,由此一方法所製作而成之有 機電激發光裝置所產生之各色光源對彩色濾光片之穿 1283379 透率不佳,容易造成各色光之色彩飽和度不佳、顯示亮 度不足及電源的浪費等問題的產生。 將可產生三原色之有機電激發光顯示元件獨立設置 之構造,如第1圖所示。主要係於一透明基板11表面分 別設置有一第一有機發光單元231、第二有機發光單元 233及第三有機發光單元235。其中,各有機發光單元 23所產生之第一光源S1、第二光源S2及第三光源S3 係分別為一紅色光源、綠色光源及藍色光源,藉由適當 比例之各色光源的混合搭配可達到該有機電激發光顯示 裝置2 0 0全彩化顯示之目的。 於透明基板11之上方設置該有機發光單元23時, 需進行一遮罩對位及蒸鍍之程序。其中,遮罩對位若出 現誤差,將會直接影響該有機發光單元23之設置。例 如,該第二有機發光單元233之遮罩對位不精確,使得 該第二有機發光單元233之設置位置出現偏移。並於原 本該設置有第二有機發光單元233的位置上產生一誤差 區域239。由於,該誤差區域239上並未設有第二有機 發光單元233,因此該誤差區域239將不會產生第二光 派S2。致使該第二有機發光單元233之作用面積由原本 A1減少為A2,而影響該第二光源S2之發光亮度及該顯 示裝置之顯示品質。 【發明内容】 為此,如何針對上述習用技術所遭遇的問題,設計出 7 1283379 一種新穎之全彩有機電激發光顯示裝置及其製作方法,針 對遮罩對位精準度的問題提出有效的解決方法,可達到有 激電機發光顯示裝置之穿透率增加與色彩飽和度提升,此 即為本發明之發明重點。 本發明之主要目的,在於提供一種四色全彩化有機電 激發光顯示裝置,其中藉由第四有機發光單元之設置,可 於其他有機發光單元之遮罩對位發生誤差時,仍可維持該 有機電激發光顳示裝置之顯示效果,並有效提高該有機電 激發光顯示裝置之產品良率者。 本發明之次要目的,在於提供一種四色全彩化有機電 激發光顯示裝置,其中藉由第一有機發光單元、第二有機 發光單元、第三有機發光單元及第四有機發光單元之設 置,可有效提高該有機電激發光顯示裝置之各色光源的穿 透率及色彩飽和度。 本發明之又一目的,在於提供一種四色全彩化有機電 激發光顯示裝置,其中藉由一白色次畫素的設置可有效提 高該有機電激發光顯示裝置之顯示色階。 本發明之又一目的,在於提供一種四色全彩化有機電 激發光顯示裝置之製作方法,不僅可降低遮罩對位時對準 確度的要求,又可有效提高該顯示裝置之光源穿透率及色 彩飽和度。 本發明之又一目的,在於提供一種四色全彩化有機電 激發光顯示裝置之製作方法,其中藉由發光效率的提昇可 有效解決大型顯示面板所面臨之耗電問題,並延長顯示面 8 1283379 板之使用壽命。 口此為達成上述目的,本發明提供一種四色全彩化 有機電激發光顯示裝置,其主要構造係包括有··一彩色濾 • 光片,主要係於一透明基板之表面設有至少一第一彩色光 • ,、至少一第二彩色光阻、至少一第三彩色光阻及至少一 第四彩色光阻;一第一電極,設置於彩色濾光片之表面; 一有機發光單元,包括有至少一第一有機發光單元、至少 _ ^第二有機發光單元、至少一第三有機發光單元及至少一 第四有機發光單元,其中第一有機發光單元、第二有機發 光單元及第三有機發光單元分別設置於彩色濾光片之第一 彩色光阻、第二彩色光阻及第三彩色光阻之垂直延伸位 置,而第四有機發光單元則設置於彩色濾光片之第一彩色 光阻、第二彩色光阻、第三彩色光阻及第四彩色光阻之垂 直延伸位置;及一第二電極,設置於該有機發光單元上。 又’為達上述目的,本發明尚提供一種四色全彩化有 φ 機電激發光顯示裝置之製作方法,其主要係包括有以下步 驟··於一透明基板之表面設置至少一第一彩色光阻、至少 一第二彩色光阻、至少一第三彩色光阻及至少一第四彩色 光阻’依此成為一彩色濾光片;形成有至少一第一電極於 該彩色濾光片上方,·放置一第一遮罩於彩色濾光片之第二 并〉色光阻、第二彩色光阻及第四彩色光阻之垂直延伸位置 ’以一第一洛鍵源進行一第一有機發光單元之蒸鑛程序; 放置一第一遮罩於彩色濾、光片之第一彩色光阻、第三彩色 光阻及第四彩色光阻之垂直延伸位置;以一第二蒸錢源進 9 1283379 行一第二有機發光單元之蒸鍍程序;放置一第三遮罩於彩 色濾光片之第一彩色光阻、第二彩色光阻及第四彩色光阻

首先,請參閱第2圖及第2 A圖,係分別為本發明四 色全彩化有機電激發光顯示裝置一較佳實施例之剖面示 意圖。如圖所示,本發明有機電激發光顯示裝置400主要 係於一彩色濾光片30上設有至少一有機電激發光元件 40。其中,該彩色濾光片30係於一透明基板31之表面設 有至少一黑色矩陣33(Black Matrix)。並於黑色矩陣33之 部分表面及該透明基板31上未設有黑色矩陣33處增設有 一具有光色過濾功能之彩色濾光層35(或稱彩色光阻)。該 彩色濾光層35係包括有一第一彩色光阻351(例如:R)、 第二彩色光阻353(例如:G)、第三彩色光阻355(例如: B)及第四彩色光阻357(係可為一透光部或鏤空部)。又, 於黑色矩陣33及彩色濾光層35上方覆蓋有一平坦障蔽單 1283379 元37,其可為一平坦化層(Over Coat)、一障蔽層(Barrier Layer)或兩者皆是。 於彩色濾光片30之平坦障蔽單元37上設置有至少一 有機電激發光元件40之第一電極41。並於該第一電極41 上依序設有一有機發光單元43及一第二電極45。該有機 發光單元43係包括有至少一第一有機發光單元431、第二 有機發光單元433、第三有機發光單元435及第四有機發 光單元437。 有機電激發光顯示裝置400中,每一個單一畫素(pixel) 内係包括有四個次畫素(sub-pixel)。並於每一次畫素上分 別設有第一彩色光阻351、第二彩色光阻353、第三彩色 光阻355及第四彩色光阻357。而該第一有機發光單元 431、第二有機發光單元433及第三有機發光單元435亦 分別設置於該晝素内之任意一個次畫素的上方。而該第四 有機發光單元437則設置於該晝素内之四個次畫素的上 方。例如,該第一有機發光單元431、第二有機發光單元 433及第三有機發光單元435係分別設置於第一彩色光阻 351、第二彩色光阻353及第三彩色光阻355之垂直延伸 位置,並與第一電極41接觸,而第四有機發光單元437 則設置於第一彩色光阻351、第二彩色光阻353、第三彩 色光阻355及第四彩色光阻357之垂直延伸位置。 層疊之第一有機發光單元431及第四有機發光單元 437所產生之第一光源S1將可穿透該第一彩色光阻351, 並過濾產生一第一色光L1。層疊之第二有機發光單元433 11 1283379 ”四有機發光單兀437所產生之第二光源S2將可穿透 該第二彩色光阻353,並過滤產生-第二色光L2。層疊之 第^有機發光單元435及第四有機發光單元437所產生之 ,三光源S3將可穿透該第三彩色光阻355,並過濾產生一 第三色光L3。該第四有機發光單元437 以將可穿透該第㈣色先阻357,並過濾產生^四 L4 〇 於本發明一實施例中,該第一有機發光單元431、第 二有機發光單元433 &第三有機發光單元435彳分別產生 a。紅色光源、一綠色光源及一藍色光源,而第四有機發光 早70 4 3 7則可產生UU。此時,該第-彩色光阻 351、第二彩色光阻353及第三彩色光阻355將分別為一 紅色光阻R(351)、綠色光阻G(353)及藍色光阻B(355), 第四彩色光阻357為一透光部或一鏤空部。經由該彩色濾 光層35過濾產生之第一色光u、第二色光L2、第三色光 L3及第四色光L4將分別為—紅色光、綠色光、藍色光及 白色光。其中,藉由該第四色光L4(白色光)與其它色光之 混合可提高該有機電激發光顯示裝置4〇〇之顯示色階。 ¥色濾光層35係為一僅容許特定波長範圍的光源通 過之裝置,並藉此達到光色過濾之目的。例如,該第一彩 色光阻351僅容許波長範圍在64〇nm〜77〇nm之間的光源 通過,當一白色光源(s)穿透該第一彩色光阻351後,第一 衫色光阻351會將波長範圍在64〇nm〜77〇nm以外的其它 色光源加以過濾阻隔。使得通過該第一彩色光阻351之色 12 1283379 : 光波長範圍介於640nm〜770nm之間,也就是肉眼所能减 受之紅色光源,藉此以達到光色過濾之目的。然而,在光 色過濾、的同時,波長在640nm〜770nm以外的色光源將合 被第一彩色光阻351過濾阻隔,將使得光源穿透率只剩 25%至35%,相對地將會降低其顯示亮度。 反之,該第一彩色光阻351所能容許色光通過之波長 範圍係如前述所言是在640nm〜770nm(紅色光阻)。則該第 一彩色光阻351對一紅色光源(例:波長分佈範圍係為 ’ 650nm〜760nm)而言將具有一良好的穿透率,例如在本發 明之實施例中,其光源穿透率即可達到70%以上。 又’於本發明實施例所述之第一有機發光單元431、 第二有機發光單元433及第三有機發光單元435與該第四 有機發光單元437之設置次序係可加以改變。例如,先於 第一電極41上設置有該第四有機發光單元437,而後再於 第四有機發光單元437上方,分別設置有該第一有機發光 k 單元431、第二有機發光單元433及第三有機發光單元 Ψ 435。 藉由該第四有機發光單元437之設置,可克服設置第 一有發光單元431、第二有機發光單元433及第三有機發 光單元435時,因遮罩對位的誤差所造成的良率損失。如 第2 A圖所示,當第二有機發光單元433於遮罩對位程序 進行時有偏移之情形發生。使得在第二彩色光阻353之垂 直延伸位置上的部分區域,形成一未設置有該第二有機發 光單元433之誤差區域439。又,由於該第二彩色光阻353 13 1283379 之垂直延伸位置上尚設置有該第四有機發光單元437,而 使得該偏移之誤差區域439上將會存在有部分之第四有機 發光單7G 437。當第四有機發光單元437所產生之第四光 源S4係為一白色光源時,該第四光源將會經由誃 極41穿透第二彩色光阻353並過濾產生相同的^二色光 L2。 因此’藉由該第四有機發光單元437之設置,將可克 服设置泫第一有機發光單元431、第二有機發光單元433 及第三有機發光單元435時,因遮罩對位的誤差所造成的 良率損失。即便該第一有機發光單元431及/或第二有機發 光單元433及/或第三有機發光單元435於遮罩對位時有^ 差’亦不會影響該有機電激發光顯示裝置400之顯示^ 質’將有利於產品良率之提昇。 再者,請參閱第3圖,係為本發明另一實施例之剖面 示意圖。如圖所示,本發明有機電激發光顯示裝置4〇1, 主要係於一彩色濾光片30上方設置有該第一有機發光單 元431、第二有機發光單元433、第三有機發光單元435 及第四有機發光單元437。其中,該第一有機發光單元 431、第二有機發光單元433、第三有機發光單元435及第 四有機發光單元437係為一可經由電流訊號導通而產生光 源之發光單元。其内部係可分別選擇包括有至少一電洞注 入層 432(Hole Injection Layer)、至少一電洞傳輸層 434(Hole Transport Layer)、至少一有機發光層(Emitting Layer)、至少一電子傳輸層 436(Electron Transport Layer)、 1283379 矣少〆電子注入層438(Electron Injecti〇n Layer)或上述各 元件組合式之其中之一。 又,該第一有機發光單元431、第二有機發光單元 433、第三有機發光單元435及第四有機發光單元437,係 選擇為一單層型有機發光單元或一複數層疊設型有機發 光單元。例如’該第一有機發光單元431、第二有機發光 單元433及第三有機發光單元435係為單層型有機發光單 元。其内部係分別包括有該第一有機發光層4311、第二有 機發光層4331及第三有機發光層4351。該第四有機發光 單元437係可為一複數層疊設型有機發光單元,其内部之 第四有機發光層4371係為一層疊之第五有機發光層4373 及第六有機發光層4375。 接續,請參閱第4圖,係為本發明又一實施例之剔面 禾意圖。如圖所示,於本發明實施例中,係於一基板32 之上表面設置有一有機電激發光元件40。在未設有該有機 電激發光元件40之基板32的部分表面則設有一封裝盏板 於該封裝蓋板39内部包覆有該有機電激發光元件40’ 藉,以保護該有機電激發光元件40並防止外界之空氣及 水乳進入。該封裝蓋板39之底層係設有一第一彩色光阻 51 第二彩色光阻353、一第三彩色光阻355及〆第四 矽,光阻357。藉此以過濾該有機電激發光元件40所產生 ,,一光源S1、第二光源S2、第三光源S3及第四光源S4。 。亥第二電極45係可選擇由一具透光導電特性之材質所製 成,藉此該第一光源S1、第二光源S2、第三光源S3及第 15 1283379 四光源S 4將可穿透該第二電極4 5 ^並達到該有機電激發 光顯示裝置403頂部發光(Top-Emission)之目的。 於本發明實施例中,當有機發光單元43於遮罩對位 時與上述之第2 A圖所示實施例一樣發生遮罩對位之誤 差時。同樣可藉由該第四有機發光單元437之設置,而有 效克服該該遮罩對位誤差所衍生的其他問題。 該具有彩色濾光層35之封裝蓋板39亦可設置於一彩 色濾光片30之透明基板31之部分上表面(如第2圖所

於第一彩色光阻551及第二彩色光阻553垂直延伸位 置之第一電極61上依序設有一第一有機發光單元631及 1283379 一第二有機發光單元633。並於該第一彩色光阻551、第 二彩色光阻553、第三彩色光阻555及第四彩色光阻557 之垂直延伸位置上設置有一第四有機發光單元637。 該第四有機發光單元637係可為一複數層疊型有機發 光單元。例如,包括有一弟五有機發光層6373及一第六 有機發光層6375。該第五有機發光層6373係為一可產生 藍色光源之有機發光層’而該第六有機發光層6375則選 擇為一可產生橙色光源、黃色光源或紅色光源之有機發光 f 層。藉由第五有機發光層6373及第六有機發光層6375適 當之搭配,將使得該第四有機發光單元637所產生之第四 光源S4為一白色光源。該白色光源在穿透第三彩色光阻 555及第四彩色光阻557後,將分別過濾產生一第三色光 L3及一第四色光L4。 又,請參閱第6圖,係為本發明又一實施例之剖面示 意圖。如圖所示,於本發明實施例中,該有機電激發光顯 _ 示裝置603,係於該一彩色滤光片50上依序設有該薄膜電 曰曰體53及平坦保護層54 ’措此以形成一 AOC(array on color filter)之結構。 該有機發光單元63係包含有:第一有機發光單元 631、第二有機發光單元633、第三有機發光單元635及第

係於第一電極41設置完成後,透過一蒸鍍之方式於第一電 極41上設置有至少一電洞注入層432及/或至少一電洞傳 輸層434。再於電洞傳輸層434上設置有至少一第一有機 發光單元431之第一有機發光層43U、至少一第二有機發 光單元433之第二有機發光層4331及至少一第三有機發光 單元435之第三有機發光層4351。 > 如第8 A圖所示,將一第一遮罩481放置於第二彩色

料461係選擇為一可產生紅色光源之有機發光材料。 如第8 B圖所示,將一第二遮罩483放置於第一彩色 光阻351、第三彩色光阻355及第四彩色光阻357之垂直 延伸位置。再以一第二蒸鍍源473進行一第二有機發光單 元433之第二有機發光層4331的蒸鍍程序。於第二彩色 光阻353之垂直延伸位置之第一電極41上形成第二有機 發光層4331。其中,該第二蒸鍍源473之第二有機發光材 料463係可依據第二彩色光阻353的顏色而進行選擇。例 1283379 如,當第二彩色光阻353係為一綠色光阻,該第二有機發 光材料463係選擇為一可產生綠色光源之有機發光材料。 如第8 C圖所示,將一第三遮罩485放置於第一彩色 光阻351、第二彩色光阻353及第四彩色光阻357之垂直 延伸位置。再以一第三蒸鍍源475進行一第三有機發光單 元435之第三有機發光層4351的蒸鍍程序。於第三彩色 光阻355之垂直延伸位置之第一電極41上形成第三有機 發光層4351。其中,該第三蒸鍍源475之第三有機發光材 料465係可依據第三彩色光阻355的不同而進行選擇。例 如,當第三彩色光阻355係為一藍色光阻,該第三有機發 光材料465係選擇為一可產生藍色光源之有機發光材料。 如第8 D圖所示,當第一有機發光層4311、第二有機 發光層4331及第三有機發光層4351設置完成之後。係可

四有機發光材料467係選擇為一可產生白色光源之有機發 光材料。 於實際應用時,該第一有機發光層4311、第二有機發 光層4331、第三有機發光層4351及第四有機發光層4371 20 1283379 之設置次序係可加以改變。例如,可先進行第四有機發光 層4371之設置,再進行第一有機發光層4311、第二有機 發光層4331及第三有機發光層4351的設置。又,該第一 有機發光層4311、第二有機發光層4331及第三有機發光 層4351之設置次序亦可加以改變。 該彩色濾光片30之第一彩色光阻351、第二彩色光阻 353、第三彩色光阻355及第四彩色光阻357之設置位置 係可加以改變。並於該第一彩色光阻351、第二彩色光阻 353、第三彩色光阻355及第四彩色光阻357之位置更改 的同時,該第一有機發光層4311、第二有機發光層4331 及第三有機發光層4351的設置位置亦隨之更改。 當第一有機發光層4311、第二有機發光層4331、第 三有機發光層4351及第四有機發光層4371設置完成之 後,可繼續有機電激發光顯示裝置400之後續製程。例如, 於第四有機發光單元437之第四有機發光層4371上,以 蒸鍍之方式依序形成至少一電子傳輸層436及/或至少一 電子注入層438與第二電極45,藉此以完成該有機電激發

Description of the Invention: [Technical Field] The present invention relates to a four-color full-color organic electroluminescence. The display device and the manufacturing method thereof can not only effectively improve the transmittance and color saturation of each color light source. It can also reduce power consumption and increase production yield. [Prior Art] # In recent years, research and development related to organic electroluminescent display devices (OLEDs), how to achieve full color display technology is often the key to the success of the organic electro-active display device, which reaches the full The most common methods for producing color display functions are as follows: 1. Separately set the organic electroluminescent elements that can produce red (R), green (G), and blue (B) colors (Side by Side), and The three color lights are mixed and matched in an appropriate ratio to produce a full-color display effect. However, during the production process, the three luminescent materials of red, green and blue must be separately evaporated. • The mask opening for each pixel is only ten microns, which will increase the difficulty of mask alignment. 2. Equipped with at least one organic electroluminescent element that produces a white light source, using a color filter that is technically sophisticated. By using a color filter to achieve the purpose of filtering a white light source, and thus producing a full color display effect. The setting method is relatively simple compared with the method of separately evaporating red, green and blue luminescent materials. However, the light source of each color light source produced by the organic electroluminescence device manufactured by the method has poor transmittance to the color filter of 1283379, and the color saturation of each color light is not good, the display brightness is insufficient, and the power source is insufficient. The generation of problems such as waste. A configuration in which an organic electroluminescence display element capable of generating three primary colors is independently provided is shown in Fig. 1. A first organic light emitting unit 231, a second organic light emitting unit 233, and a third organic light emitting unit 235 are disposed on the surface of a transparent substrate 11, respectively. The first light source S1, the second light source S2, and the third light source S3 generated by each of the organic light-emitting units 23 are respectively a red light source, a green light source, and a blue light source, which can be achieved by mixing and matching the light sources of appropriate colors. The organic electroluminescent display device has the purpose of displaying a full color display. When the organic light-emitting unit 23 is disposed above the transparent substrate 11, a mask alignment and vapor deposition process is required. If the error occurs in the mask alignment, the setting of the organic light emitting unit 23 will be directly affected. For example, the mask alignment of the second organic light emitting unit 233 is inaccurate such that the set position of the second organic light emitting unit 233 is shifted. An error region 239 is generated at a position where the second organic light emitting unit 233 is originally disposed. Since the second organic light emitting unit 233 is not provided on the error region 239, the error region 239 will not generate the second light level S2. The area of the second organic light-emitting unit 233 is reduced from the original A1 to A2, which affects the luminance of the second light source S2 and the display quality of the display device.

Further, a black mask 33 and a color filter layer 35 are overlaid with a flat barrier sheet 1283379, which may be an over Coat, a barrier layer or both. The first electrode 41 of the at least one organic electroluminescent element 40 is disposed on the flat barrier unit 37 of the color filter 30. An organic light emitting unit 43 and a second electrode 45 are sequentially disposed on the first electrode 41. The organic light emitting unit 43 includes at least one first organic light emitting unit 431, a second organic light emitting unit 433, a third organic light emitting unit 435, and a fourth organic light emitting unit 437. In the organic electroluminescent display device 400, each single pixel includes four sub-pixels. A first color photoresist 351, a second color photoresist 353, a third color photoresist 355, and a fourth color photoresist 357 are respectively disposed on each pixel. The first organic light emitting unit 431, the second organic light emitting unit 433, and the third organic light emitting unit 435 are also disposed above any of the secondary pixels in the pixel. The fourth organic light-emitting unit 437 is disposed above the four sub-pixels in the pixel. For example, the first organic light emitting unit 431, the second organic light emitting unit 433, and the third organic light emitting unit 435 are respectively disposed on the vertical extension of the first color photoresist 351, the second color photoresist 353, and the third color photoresist 355. Positioned and in contact with the first electrode 41, and the fourth organic light emitting unit 437 is disposed on the vertical extension of the first color photoresist 351, the second color photoresist 353, the third color photoresist 355, and the fourth color photoresist 357 position.

The stacked second organic light emitting unit 433 11 1283379 "the second light source S2 generated by the four organic light emitting unit 437 will penetrate the second color resist 353 and filter to generate - the second color light L2. The three light sources S3 will pass through the third color photoresist 355 and be filtered to generate a third color light L3. The fourth organic light emitting unit 437 will be transparent.

The color filter layer 35 is a device that allows only a light source of a specific wavelength range to pass through, and thereby achieves the purpose of color filter. For example, the first color photoresist 351 is only allowed to have a wavelength range of 64 〇 nm~ A light source between 77 〇 nm passes through. When a white light source (s) penetrates the first color photoresist 351, the first shirt color resist 351 emits other color light sources having a wavelength ranging from 64 〇 nm to 77 〇 nm. Filtering is blocked, so that the color 12 1283379 passing through the first color photoresist 351 has a wavelength range of 640 nm to 770 nm, that is, a red light source that can be reduced by the naked eye, thereby achieving the purpose of color filter. However, in the case of light color filtering, the color light source having a wavelength other than 640 nm to 770 nm is filtered and blocked by the first color photoresist 351, so that the light source transmittance is only 25% to 35%, which is relatively lowered.

As shown in Fig. 2A, the second organic light emitting unit 433 is offset when the mask alignment process is performed. An error region 439 in which the second organic light-emitting unit 433 is not disposed is formed in a partial region at a vertically extending position of the second color resist 353. Moreover, since the fourth organic light emitting unit 437 is still disposed at a vertical extending position of the second color photoresist 353 13 1283379, a portion of the fourth organic light emitting unit 7G is present on the offset error region 439. 437. When the fourth light source S4 generated by the fourth organic light emitting unit 437 is a white light source, the fourth light source will penetrate the second color photoresist 353 via the cathode 41 and filter to generate the same dichromatic light L2.

A portion of the fourth organic light-emitting layer 4371 is positioned on the upper surface of the first organic light-emitting layer 4311, the second organic light-emitting layer 4331, and the third organic light-emitting layer 4351. The fourth organic light-emitting material 467 of the fourth evaporation source 477 is selected as an organic light-emitting material capable of generating a white light source. In practical applications, the order of arrangement of the first organic light-emitting layer 4311, the second organic light-emitting layer 4331, the third organic light-emitting layer 4351, and the fourth organic light-emitting layer 4371 20 1283379 may be changed. For example, the fourth organic light-emitting layer 4371 may be disposed first, and then the first organic light-emitting layer 4311, the second organic light-emitting layer 4331, and the third organic light-emitting layer 4351 may be disposed. Further, the order of arrangement of the first organic light-emitting layer 4311, the second organic light-emitting layer 4331, and the third organic light-emitting layer 4351 may be changed. The positions of the first color photoresist 351, the second color photoresist 353, the third color photoresist 355, and the fourth color photoresist 357 of the color filter 30 can be changed. And the first organic light-emitting layer 4311 and the second organic light-emitting layer 4331 are simultaneously changed at positions of the first color photoresist 351, the second color photoresist 353, the third color photoresist 355, and the fourth color photoresist 357. The installation position of the third organic light-emitting layer 4351 is also changed. After the first organic light-emitting layer 4311, the second organic light-emitting layer 4331, the third organic light-emitting layer 4351, and the fourth organic light-emitting layer 4371 are disposed, the subsequent process of the organic electroluminescent display device 400 can be continued. For example, at least one electron transport layer 436 and/or at least one electron injection layer 438 and the second electrode 45 are sequentially formed on the fourth organic light-emitting layer 4371 of the fourth organic light-emitting unit 437 by evaporation. The setting of the organic electroluminescent display device 400 is completed. In the above-mentioned production process, the vapor deposition of the organic light-emitting unit 43 is independently set to the organic electroluminescent light elements of the three primary colors of red (R), green (G), and blue (B) to form organic electroluminescent light. In terms of the arrangement of the display device, it is possible to overcome the yield loss caused by the accuracy error in the mask alignment program, and thereby achieve the improvement of the product yield of the full-color organic electroluminescent display device 400. 21 1283379 Of course, the above process steps are equally applicable to an active matrix organic electroluminescent display device, a first organic light emitting unit (631), a second organic light emitting unit (633), and a third organic light emitting unit (635). And the fourth organic light emitting unit (637) can also be formed in order, and will not be described herein. In summary, the invention relates to a full-color organic electroluminescent display device and a manufacturing method thereof, which can not only effectively improve the transmittance and color saturation of each light source, but also overcome the mask alignment program. Those who suffer from yield loss due to accuracy errors and increase production yield. Therefore, the present invention is a novelty, progressive, and available for industrial use.
