‘ 第二基板130配置於電泳顯示層12〇 H 工·不。第二基板 201250357 130可為一透明基板,例如玻璃基板或其他透明基板。在 一實施例中’電泳顯示器100為一反射式的顯示器,入射 光可經由第二基板130進入電泳顯示層120,然後光線被 電泳顯示層120中的電泳顯示單元124反射後,再經第二 基板130而離開電泳顯示器1〇〇。因此,使用者可在第二 基板130的外側觀看及使用電泳顯示器1〇〇。但是,本發 明亦可使用於穿透式的顯示裝置中。 表面應力層140位於第二基板13〇的下表面,並與黏 著層150相接觸。因此,第二基板13〇不會直接接觸黏著 層150。在一實施例中,表面應力層14〇為一含氟高分子 的絕緣材料所製成,其厚度可為約0.2 //m至約2 /zm。 =此實施例中,可藉由一旋轉塗佈製程,先形成一含氟高 分子的溶液層,然後再經由高溫烘烤而形成表面應力層14〇 於第一基板130的下表面。待表面應力層硬化後,再 以黏著層150與電泳顯示層12〇黏合。 黏著層150配置於表面應力層14〇與電泳顯示層12〇 之間’且接觸電泳顯示| 12〇與表面應力層刚。黏著層 =〇用以黏結第一基板11〇上的電泳顯示層與第二基 ^ ;30上的表面應力们4〇’而使第一基板ιι〇、電泳顯示 获2、第二基板130以及表面應力層140形成密合的封 。在本實施例中,表面應力層140與黏著層150間 :力為電泳顯示層12〇與黏著層15〇間之黏著力的約 。約125%,例如為約85%至約115%。在一實施例 泳顧力I 140與黏著層150間之黏著力大致等於電 〜不胃20與黏著層15〇間之黏著力。在另一實施例中, 201250357 表面應力層140與黏著層150間之黏著力略大於或大致等 於電泳顯示層120與黏著層150間之黏著力。黏著層150 可例如為一紫外光硬化膠所製成。在一實施例中,黏著層 150包覆電泳顯示器1〇〇的外緣1〇2,以增強第一基板no 與第一基板13〇之間的接著強度,並可防止水氣或污染物 進入電泳顯示器100中。 控制表面應力層140與黏著層150之間的黏著力以及 電泳顯示層120與黏著層150之間的黏著力是重要的。第 2A圖繪示本發明一比較例之剖面示意圖。在比較例中,第 二基板130為玻璃基板,黏著層15〇為一紫外光硬化膠, 電泳顯示層120的基材122為PET材料所製成。第二某 130的下表面未設置表面應力層14〇,第二基板13〇直接斑 黏著層150接觸。換言之,黏著層15〇直接將第二基板⑽ ,結在電泳顯示層12〇上。然而,比較例中的黏著層15〇 ,過紫外光照射硬化後’黏著層15〇與電泳顯示層12〇 在局部區域發生㈣縣,且特财易發 =的邊緣處,如第2A圖箭頭F所指處。所以,】 剝離區域發生異常的光學路徑,也因此、、。 在邊緣處的心效果與其他正常區 嚴 =:γ_ε所指的情況二^ 電泳顯示層⑽與第-基板 功能。以·』7^刚的邊緣處喪失正常的顯示 本發明之發明人為改善上述問題,嘗試多種不同的製 201250357 =條:以及不同黏著層材料,均不容易 ;。發明人更進-步究其原因後發現,常用的黏著4: 材:璃破?材料之間的黏著力大於其他種基材 為其斑黏者層15G與玻璃基板之間的黏著力約 jfPET基材122之間黏著力的1.5倍。例如,在相同 、面積下’黏著層15〇與玻璃基板之間的黏著力為約 4’一而黏著層150與pET基材122之間黏著力僅約 g換:之黏著層15〇與第二基板13〇之間的黏著力遠 =黏著層15G與電泳顯示層12G的ρΕΤ基材122之間的 黏著力。t以紫外光照射而使黏著層15〇硬化時,黏著層 150發生收縮(Shrinkage)現象,再因上述黏著力的差異,而 造成黏著層150與電泳顯示層12〇在局部區域發生剝離現 象0 因此,根據本發明之實施方式,在第二基板13〇的下 表面叹置表面應力層14〇,使表面應力層14〇與黏著層 間之黏著力為電泳顯示層12〇與黏著層15〇間之黏著力的 約75 %至約125 °/〇,從而改善上述問題。 請參見第3圖,其為本發明另一實施方式之電泳顯示 器100的剖面示意圖。在本實施方式中,電泳顯示器1〇〇 大致與第1圖繪示之實施方式相同,不同之處在於,第二 基板130包括有一透明基板131、一彩色光阻層is]以及 一透明電極層134。彩色光阻層132配置在透明基板131 的内側表面上,而使電泳顯示裝置100呈現彩色的顯示功 能。詳言之,可在透明基板131上形成圖案化的紅色光阻 層區域132R、綠色光阻層區域132G及藍色光阻層區域 201250357 132B且母一顏色的光阻層區域對應一個晝素電極114〇 因此’可形成全彩的電泳顯示器!⑽。透明電極層134配 置在彩色光阻層U2上,並藉由透明電極層134與畫素電 極114之間形成電場來控制電泳顯示單丨124的顯示狀 態。在上述實施例中,表面應力们4G配置在透明電極層 134的下表面。表面應力層14〇與黏著層15〇相接觸。在 其他實施例中’電泳顯示器⑽可為平面切換(ΐη他狀 Switchmg,IPS)式的顯示器,因此彩色光阻層132上無須配 置透明電極層134。在此實施例中,表面應力| 14〇可配 置在彩色光阻層132上。 雖然本發明已以實施方式揭露如上,然其並非用以限 定本發明,任何熟習此技藝者,在不脫離本發明之 範圍内,當可作各種之更動與潤飾,因此本發明之保護範 圍當視後附之申請專利範圍所界定者為準。 【圖式簡單說明】 為讓本發明之上述和其他目的、特徵、優點與實施 能更明顯易懂,所附圖式之說明如下: 第1圖係繪示本發明-實施方式之電泳顯示器的剖面 不意圖。 第2A及2B圖係繪示本發明一比較例之剖面示意圖。 —第3圖係繪示本發明另一實施方式之電泳顯示:的剖 rtn —r* ·Β* Ι^ι λ ’ 【主要元件符號說明】 201250357 100電泳顯示器 102電泳顯示器外緣 110第一基板 111上表面 112驅動元件 114晝素電極 120電泳顯示層 122基材 123下表面 124電泳顯示單元 126膠層 130第二基板 131透明基板 132彩色光阻層 132R紅色光阻層區域 132G綠色光阻層區域 132B藍色光阻層區域 134透明電極層 140表面應力層 150黏著層 E, F箭頭
