201210812 六、發明說明: 【明戶斤屬々貝3 發明領域 本發明係關於頗適於面材接合的硬化性樹脂組成物、 使用該硬化性樹脂組成物進行面材層積的層積體、以及該 層積體之製造方法。 發明背景 在顯示元件上隔著接合樹脂層進行保護板層積的顯示 裝置,當使接合樹脂層硬化時,因該接合樹脂層的收縮所 產生應力會有對顯示元件造成影響之可能性。若對顯示元 件施加應力,便會發生下述問題。 •顯示元件中的顯示形成材料(以下稱「顯示材」)會因 應力而受影響,會有損及顯示均勻性之虞。例如#液晶顯 示元件的情況而言’顯示元件中所封入液晶的排列會因外 部應力而凌亂,導致被檢視到顯示斑。 •當在顯示元件靠顯示面側之基板表面上,形成諸如 視野角等為改善顯示品質用的光學膜時,因應力會導致該 光學膜的光學特性出現局部性變化,而有損及顯示之均句/ 性之虞。 再者’因為接合樹脂層係設置於顯示元件的檢視側,因 而若硬化的接合樹脂層中有存在氣泡,便會發生下述問題。 •來自顯示元件的出射光或反射光會因氣泡而凌亂, 會有大幅損及顯示影像之晝質之虞。 3 201210812 因為通過保護板殘存 •當顯示元件沒有顯示影像時 因而會有大幅損 於接合樹脂層中的氣泡較容易被檢視到 及製品品質的可能性。 •樹脂層與㈣元件間之界面料力、賴脂層與保 濩板間之界面接著力會降低。 —製造具有在顯示元件上層積有透明面材之層積構造顯 示裝置的方法,已知有如下述方法。 ⑴在樹脂製紐板上注人液態原料使硬化㈣成接合 樹脂後’或將捲片狀接合樹脂以脫氣狀態貼設於樹脂製保 護板上之後,-邊將液晶單元從—端按押—邊使以脫氣狀 態進行密接並層㈣方法i合飽旨的補較佳係使用聚 矽氧凝膠(專利文獻1)。 (2)在玻璃製保護板的狀位置處,利賴著構件將顯 示面板予以定位而暫時固定後,再對保護板與顯示面板之 間所形成的空間中,以減壓狀態注人液態樹脂材料並使硬 化,藉此而層積的方法。液態樹脂材料較佳係使用聚矽氧 樹脂(專利文獻2)。 先行技術文獻 專利文獻 專利文獻1:日本專利特開平7-209635號公報 專利文獻2 :曰本專利特開2006-58753號公報 【發明内容】 發明概要 發明欲解決之課題 201210812 ▲根據本發明者等的發現,藉由降低形成接合樹脂層的 树月日之極性與分子量,便可使接合樹脂層的彈性模數降 低。若在顯示元件與透日㈣材間所介存的接合樹脂層之彈 性模數降低,則硬化收縮時所產生的應力便會變小,俾可 抑制對顯示品質的影響。 然而,僅依賴降低#合樹脂層的彈性模數,會有將顯 示元件與透明面材予以固^的力嫌不^之情況例如當顯 示裝置係呈垂直設置使用時,顯示树會有經時性從透明 面材上偏移脫落、或脫離的可能性。 又,雖亦考慮在接合樹脂層的原料方面盡可能使用高 分子量的硬化前驅體化合物,俾使硬化反應之結合部位數 相對地減少,藉此使接合樹脂層的彈性模數降低之方法, 但未硬化時的組成物黏度變得過高而恐有難以注入或塗佈 之虞。此外,若因結合部位數減少而使得硬化後樹脂層的 交聯密度變得過小,帛以固定顯示元件與透明面材的力道 將變得不夠’例如當顯示裝置係呈#直設置❹時,顯示 元件會有經時性從透明面材上偏移脫落、或脫離的可能性。 本發明係有鑒於前述事情而完成,目的在於提供:當 隔著由硬化性樹脂組成物的硬化物所構成的樹脂層,將面 材層積一體化時,可將面材彼此間予以充分固定,且可降 低因樹脂層硬化時的收縮而產生之應力的硬化性樹脂組成 物及已使用該硬化性樹脂組成物進行面材之層積的層積 體。 再者,本發明目的在於提供:當隔著由硬化性樹脂組 201210812

圖示例的顯示元件50係將設有彩色濾光片的透明面材 52、與設有TFT的透明面材53進行貼合,再將其利用一對偏 光板51夾持而構成的液晶顯示元件一例,但本實施形態的 顯示元件並不侷限於圖示例。 顯示元件係在至少其中一者為透明電極的一對電極 中,挾持利用外部之電氣信號而變化光學樣態的顯示材。 依照顯示材的種類,有諸如:液晶顯示元件、EL顯示元件、 電漿顯示元件、電子墨水型顯示元件等。又,顯示元件係 具有貼合一對面材且該一對面材至少一者為透明面材的構 造,並配置成透明面材側鄰接於樹脂層。此時,部分的顯 示元件係在與樹脂層相鄰侧的透明面材最外層側,設置諸 如偏光板、相位差板等光學膜。此情況,樹脂層係呈顯示 元件上的光學膜與表面材相接合的樣態。 12 201210812 對顯不元件與樹脂層的接合面,為提升與密封部間之界 面接著力,亦可施行表面處理。表面處理係可僅對周緣部施 灯’亦可對面材的整體表面實施。表面處理的方法有如利用 可低溫加工的接著用底漆等施行處理之方法等。 顯不元件的厚度係當屬於利用TFT啟動的液晶顯示元 件時,通常為0.4〜4mm,當屬於EL顯示元件時通常為 0·2〜3mm。 [樹脂層] 樹脂層係由本發明的硬化性樹脂組成物(以下亦稱「樹 脂層形成用光硬化性樹脂組成物」)進行硬化而構成的層。 本發明的硬化性樹脂組成物(本實施形態的樹脂層形 成用光硬化性樹脂組成物),係可降低硬化後的彈性模數, 並可降低進行硬化時所產生的應力。所以,可抑制因該應 力對顯示元件的顯示性能造成不良影響。又,該硬化性樹 脂組成物在未硬化時的黏度較低,所以能在短時間施行對 面材表面的硬化性樹脂組成物供應,因而容易防止在表面 材與背面材的層積後出現氣泡殘留情形。 樹脂層的厚度較佳係0_03〜2mm、更佳係〇.1〜〇.8mm、 特佳係0.2〜0.6mm。若樹脂層的厚度達〇.〇3mm以上,樹脂 層便可有效的緩衝因來自透明面材側的外力所造成衝擊 專’俾可保護顯示元件。特別係當顯示元件對外力屬於敏 銳,較容易影響顯示品質的情況’較佳係設成達0.2mm以 上的厚度。又,本實施形態的製造方法中,即便在透明面 材與顯示元件之間混入超越樹脂層厚度的異物,樹脂層的 13 201210812 厚度仍不會有太大的變化’對光穿透性能的影響較少。若 樹脂層的厚度在2mm以下’在樹脂層中不易殘留氣泡,且 顯示裝置的整體厚衫會成W餘的厚。讀脂層的彈性 模數較小之情況,物制顯示元件經時性接合位置偏移等 情形,較佳係設為〇.6mm以下的厚度。 调整樹脂層厚度的方法,係有如調節後述密封部的厚 度’且同時調節對第丨面材所供應之液狀樹脂層形成用光硬 化性樹脂組成物的供應量之方法。 [密封部] 密封部係塗佈後述液狀密封部形成用光硬化性樹脂組 成物,經硬化而構成者。因為顯示元件的影像顯示區域之 外側區域比較狹窄,因而密封部的寬度以狹窄為宜。密封 部的寬度較佳係0.5〜2mm、更佳係ο』〜i.6mm。 [遮光印刷部] 視需要,可在透明面材的周緣部設置遮光印刷部。遮 光印刷部係依顯示元件的影像顯示區域之外均無法從透明 面材側看到的方式,隱藏連接於顯示元件的配線構件等。 遮光印刷部係可設置於透明面材與樹脂層的接合面、或其 背面’就降低遮光印刷部與影像顯示區域的視差之觀點, 以设置於透明面材與樹脂層的接合面為佳。當透明面材係 玻璃板的情況,若遮光印刷部係使用含黑色顏料的陶瓷印 刷’則遮光性較高,屬較佳。藉由將表面或背面已設有遮 光印刷部的透明薄膜貼合於透明面材上,亦可形成遮光印 刷部。亦可使用沒有遮光印刷部的透明面材。 201210812 [形狀] 顯示裝置的形狀通常係矩形。 顯示裝置的大小並無特別的限定,因為本實施形態的 製造方法特別適用於較大面積之顯示裝置的製造,因而告 屬於採用液晶顯示元件之情況,以pc螢幕的情況而言較佳 為(Umx〇.i8m,以電視接收器的情況而言較佳為〇 以上、更佳為〇.7mx〇.4m以上》顯示裝置的大小上限大多係 依照顯示元件的大小而決定。又,過大的顯示裝置在^置 等處理上容易趨於困難。顯示裝置的大小上限係從鸪等阼 制觀之’通常為2.5mxl_5m程度。小型顯示器的情況,較佳 為 0.14mx〇.〇8m 以上。 成為保護板的透明面材' 與顯示元件的尺寸係可為大 致相等,但就與收納顯示裝置的其他框體間之關係,多數 情況係透明面材較顯示元件大一圈。又,相反的依照其他 框體的構造,亦可使透明面材若干小於顯示元件。 <顯示裝置之製造方法> 本貫施形態的顯示裝置之製造方法,係包括有下述步 驟(a)〜(d)的方法。 ’ V 弟i面材(月曲材(或表面材))的表面周緣部,塗佈 含有硬化性化合物(I)及光聚合起始劑(α)的液狀密封 成用光硬化性樹脂組成物,而形成未硬化密封部的㈣ (但,當第1面材係顯示元件的情況,便在影像顯示側的表 面上形成密封部)。 (b)對未硬化柳卩所包_區域,供應含有硬化性化 15 201210812 合物(π)與光聚合起始劑(C2)的液狀樹脂層形成用光硬化性 樹脂組成物之步驟。 (c) 在lOOPa以下的減壓環境下,於樹脂層形成用光硬化 性樹脂組成物上重疊第2面材(表面材(或背面材)),而獲得 樹脂層形成用光硬化性樹脂組成物已由第丨面材、第2面材 及未硬化密封部加以密封之層積前驅體的步驟(但,當在第 2面材的表面設有抗反射膜時,便依其背面側的表面鄰接樹 脂層形成用光硬化性樹脂組成物的方式重疊。又,當第2面 材係顯示元件的情況’便依影像顯示側鄰接於樹脂層形成 用光硬化性樹脂組成物的方式重疊)。 (d) 將層積前驅體放置於5〇kPa以上之壓力環境下並於 此狀態下,對未硬化密封部及樹脂層形成用光硬化性樹脂 組成物施行光照射,而使硬化的步驟。 當透明面材上沒有形成遮光部的情況,便從層積前驅 體靠透明面材側,透過透光部對密封部及樹脂層形成用光 硬化性樹脂組成物照射光。 當在透明面材的周緣部有形成遮光部的情況,由該遮 光部所包圍的透光部面積,係小於由密封部所包圍的樹脂 層面積,且上述樹脂層形成用光硬化性樹脂組成物中所含 光聚合起始劑(C2)所具有的吸收波長區域(;12),較上述密 封部形成用光硬化性樹脂組成物中所含光聚合起始劑(Ci) 的吸收波長區域(λ 1)更靠長波長側存在,而使在上述步驟 (d)中從層積前驅體的側邊所照射的光,涵蓋吸收波長區域 (λ 1)内的波長光及吸收波長區域(又2)内的波長光。 16 201210812 本貫施形態的製造方法係在減壓環境下,於第丨面材與 第2面材之間封入液狀樹脂層形成用光硬化性樹脂組成 物,在大氣壓環境下等高壓力環境下,使所封入的樹脂層 形成用光硬化性樹脂組成物硬化而形成樹脂層的方法(減 壓層積方法)。在減壓下進行樹脂層形成用光硬化性樹脂組 成物的封入,並非在第1面材與第2面材的間隙之窄而寬空 間中注入樹脂層形成用光硬化性樹脂的方法,而是對第丄面 材的幾乎整面供應樹脂層形成用光硬化性樹脂組成物,然 後重疊上第2面材,而在第1面材與第2面材之間封入樹脂層 形成用光硬化性樹脂組成物的方法。 在減壓下進行液狀樹脂層形成用光硬化性樹脂組成物 的封入、以及在大氣壓下利用樹脂層形成用光硬化性樹脂 組成物的硬化而進行透明層積體的製造方法一例,係屬公 知。例如國際公開第2008/81838號小冊子、國際公開第 2009/16943號小冊子所記載的透明層積體之製造方法、以 及該製造方法所使用的光硬化性樹脂組成物,均納入於本 說明書中。 [步驟⑷] 首先,沿第1面材一表面的周邊部形成未硬化密封部。 第1面材係可任意使用背面材、或使用表面材。 第1面材係當屬於成為顯示元件之保護板的透明面材 時’形成未硬化密封部之面係可任意為2個表面中之任一 面。當2個表面的性狀不同等情況時便選擇需要的一表面。 例如當其中一表面有施行為提升與樹脂層間之界面接著力 17 201210812 的表面處理時,便在該表面上形成未硬化密封部。又,卷 虽 在其中一表面上設有抗反射層的情況,便在其背面形成未 硬化密封部。 ¥第1面材係顯示元件的情況’形成未硬化密封部之 面便為影像顯示側的表面。 未硬化密封部重點在於:在後述步驟(C)中,具有、夜狀 樹脂層形成用光硬化性樹脂組成物不會從未硬化密封部與 第1面材間之界面、以及從未硬化密封部與第2面材間之界 面處茂漏出程度以上的界面接著力’以及具有能維持形狀 之程度的堅固度。所以,未硬化密封部最好係將黏度較高 的社封部形成用光硬化性樹脂組成物,利用諸如印刷、八 配等施行塗佈而形成。 再者’為保持第1面材與第2面材間之間隔,亦可在密 封部形成用光硬化性樹脂城物巾雜既定純的間隔粒 在达、封部形成用光硬化性樹脂組成物剛塗佈後,亦可 立即藉由照射用以使密封部硬化的光而使密封部呈局部性 半硬化,使密封部的形狀維持更長時間維持。 [密封部形成用光硬化性樹脂組成物] 密封部形成用光硬化性樹脂組成物(以下亦稱「密封 材」)’係含有光硬化性之硬化性化合物⑴與光聚合起始劑 (C1)的液狀組成物。 密封部形成用光硬化性樹脂組成物的黏度,較佳係 500〜3_Pa · S、更佳係_〜2500Pa · S、特佳係1〇〇〇〜 201210812 2000Pa· s。若黏度達500Pa· s以上,便可較長時間維持未 硬化密封部的形狀,可充分維持密封部的高度。若黏度在 3000Pa . s以下,便可利用塗佈法形成密封部。 密封部形成用光硬化性樹脂組成物的黏度,係在25它 下’使用E型黏度計進行測定。 (硬化性化合物(I)) 硬化性化合物⑴係就容易將密封部形成用光硬化性樹 脂組成物的黏度調整於前述範圍内的觀點,較佳係含有寡

烯醯氧基所構成群組的基。 募聚物(A)中之硬化性基、與單體(B)中之硬化性基係可 互為相同、亦可為不同。因為分子量較高的寡聚物中之 硬化性基,反應性容易變得低於分子量較低的單體(B)中之 硬化性基,因而會有單體(B)的硬化先行進行導致組成物整 體的黏性急遽提高,造成硬化反應呈不均質的可能性。為 忐縮小二者硬化性基的反應性差,俾可獲得均質的密封 部,最好將寡聚物(A)中之硬化性基設為反應性較高的丙烯 醯氧基,並將單體(B)中之硬化性基設為反應性較低的甲基 201210812 丙烯醯氧基。 寡聚物(A)的數量平均分子量係30000〜100000、較佳係 40000〜80000、更佳係5〇000〜65000。若寡聚物(A)的數量平 均分子量在該範圍内,便容易將密封部形成用光硬化性樹 脂組成物的黏度調整於前述範圍内。 寡聚物(A)的數量平均分子量係利用Gpc測定而獲 得,屬於聚苯乙烯換算的數量平均分子量。另外,Gpc測 定中’當有ib現未反應之低分子量成分(單體等)的尖峰時, 便排除該尖峰求取數量平均分子量。 單體(B)的分子量係125〜_、較佳係14〇〜4〇〇、更佳係 150〜350。若單體(B)的分子量達125以上當利用後述減壓 層積方法進行顯示裝置製造時,便可抑制單體⑼的揮發。 若單體(_分子4在_町,便可提高單體(酬高分子 .

多元醇、聚異氰酸酯係屬於公知化合物,例如國際公開 第2009/016943號小冊子所記載當作胺曱酸酯系寡聚物(&)之 21 201210812 原料的多兀醇⑴、二異氰酸酯(…等,均納入於本說明書中。 多元醇⑴係可舉:聚氧乙二醇、聚氧伸丙基二醇等聚 氧伸烧基多元醇;聚酷多元醇、聚碳酸醋多元醇等。該等 之中’較佳係聚氧伸院基多元醇、更佳係聚氧伸丙基多元

合物(II)單獨進行硬化反應的硬化物中便存在羥基。該經基 的存在係對樹脂層形成用光硬化性樹脂組成物中的非硬化 性寡聚物安定化具有貢獻。 所以,具有前述硬化時不會產生反應之羥基的化合物 (Ila)’只要是硬化反應後有存在未反應羥基便可 ,例如即 使化合物(Ila)的羥基一部分進行硬化反應,另一部分未進 行硬化反應而以未反應狀態殘留的話便可。 該具有硬化時不會產生反應之羥基的化合物(IIa),係

藉由使樹脂層形成用光硬化性樹脂組成物含有非硬化 ,[生寡聚物(D) ’便可在上述抑制硬化後的樹脂層損失正切 (一)上升之情況下,使料剪切彈性模數降低,因而可同 恃達成動態黏彈性測定中储存剪切彈性模數與損失正切 (taM)的各自較佳範圍。 (添加劑) 樹脂層形成用光硬化性樹脂組成物係視需要,尚可含 有諸如:聚合終止劑、光硬化促進劑、鏈轉移劑、光安定

月曰組成物的第1面材,放入減壓裝置中,並在減壓裝置内的 固定支撐盤上,依硬化性樹脂組成物之面朝上的方式,平 放第1面材。 在減壓裝置内的上部,設有可於上下方向移動的移動 支撐機構,在移動支撐機構上安裝有第2面材。當第2面材 係顯示元件的情況,便將顯示影像該側的表面朝下。當在 第2面材的表面設有抗反射層之情況,便將沒有形成抗反射 層之一側的表面朝下。 第2面材係放置於第1面材的上方,且不與樹脂層形成 40 201210812 用光硬化性樹脂组成物接觸的位置處。即,使第1面材上的 樹脂層形成用光硬化性樹脂組成物、與第2面材不會相接觸 地呈相對向。 另外,亦可將於上下方向移動的移動支撐機構設置於 減壓裝置内的下部,並在移動支撐機構之上放置已被供應 硬化性樹脂組成物的第1面材。此情況’第2面材係安裝於 在減壓裝置内的上部所設置之固定支撐盤上,並使第1面材 與第2面材呈相對向。 再者,亦可將第1面材與第2面材二者均由設置於減壓 裝置内的上下之移動支撐機構所支撐。 將第1面材與第2面材配置於既定位置後,便對減壓褒 置的内部施行減壓而形成既定的減壓環境。若可能的話, 亦可在減壓操作中、或經形成既定減壓環境之後,便在減 壓裝置内使第1面材與第2面材位於既定位置處。 在減壓裝置的内部成為既定減壓環境之後,便將由移 支樓機構所支樓的第2面材朝下方移動,俾使第2面材重

mm的較厚狀雜。 42 201210812 [步驟(d)] 在步驟(c)中’經解除減壓環境後,便將層積前驅體放 置於環境壓力達50kPa以上的壓力環境下。 若將層積前驅體放置於50kPa以上的壓力環境下,第1 面材與第2面材便利用上升的壓力朝相密接的方向被按押’ 因而若在層積前驅體内的密閉空間中有存在氣泡,樹脂層形 成用光硬化性樹脂組成物會流動於氣泡中,便使密閉空間整 體由樹脂層形成用光硬化性樹脂組成物均勻地填充。 壓力環境通常係80kPa〜120kPa。壓力環境係可為大氣 壓%境、亦可為較高於此的壓力。就樹脂層形成用光硬化 性樹脂組絲的硬化轉作可在不需要制設備情況下實 施的觀點,較佳為大氣壓環境。 從將層積前驅體放置於50kPa以上的壓力環境下之時 點起、迄樹脂層形細級化性樹脂組成物開始硬化為止 的寺門(乂下稱「南壓保持時間」)並無特別的限定。當將層 積月J驅體從減壓裝置中取出並移動至硬化裝置,直到開始 更化為止的t程均在大氣壓環境下進行的情況此項製程 ,需=時間便成為縫料時間。所以,當在放置於大 氣 兄下的時點,於層積前驅體的密閉空間内已無存在 氣泡的情況’或者在該製程期間錢泡;肖㈣情況,均可 馬脂層形成用光硬化性樹脂組成物硬化。當直到氣 均將声積時間的情況,便在截至氣泡消失為止前, 均將層^驅體保持於通㈣上的動環境下。又,因為 即便尚壓保持時間延長,通常仍不會構成阻礙,因而就製 43 201210812 程上的其他必要性,亦可延長高壓保持時l高壓保持時 間係可為1日以上的長時間,但就生產效率的觀點較佳係 6小時以内、更佳係1小時以内’就提高生產效率的觀點, 特佳在10分鐘以内。 接著,以將層積前驅體放置於5〇kPa以上的壓力環境下 之狀態,藉由使樹脂層形成用光硬化性樹脂組成物進行硬 化,便形成將顯示元件與保護板予以接合的樹脂層,可製 得顯示裝置》 樹脂層形成用光硬化性樹脂組成物及密封部形成用光 硬化性樹脂組成物’係照射光而使硬化。例如從光源(諸如 紫外線燈、高壓水銀燈、黑燈、化學燈、UV_LED等)照射 紫外線或短波長可見光,而使光硬化性樹脂組成物硬化。 再者’此時’由密封部形成用光硬化性樹脂組成物所 形成的未硬化密封部,係可與樹脂層形成用光硬化性樹脂 組成物的硬化同時進行硬化,亦可在樹脂層形成用光硬化 性樹脂組成物進行硬化前便使預先硬化。又,當透明面材 其中一部分有形成遮光印刷部,並由遮光印刷部挾持而形 成密封部的情況,因為在樹脂層形成用光硬化性樹脂組成 物的硬化時所採取之利用通過透明面材之透光部的光而使 密封部硬化係有困難,因而亦可在樹脂層形成用光硬化性 樹脂組成物硬化之後才使密封部硬化。 例如從層積前驅體的第1面材及第2面材中具有光穿透 性之側,對樹脂層形成用光硬化性樹脂組成物施行光照 射’且從層積前驅體側邊,對由遮光部及顯示元件所包夾 44 201210812 的未硬化密封部及樹脂層形成用級化性樹脂組成物,施 行光照射。 第1面材及第2面材當中,因為顯示元件在未使啟動的 狀態下並不具有光穿透性,因而從成為保護板的透明面材 之側通過透光部施行光照射。 再者,若在透明面材的周邊部設置遮光印刷部,並在 由遮光印刷部與顯示元件所挾持的區域巾有存在未硬化密 封。p或糾旨層形成用光硬化性樹脂組成物則僅依靠來自 透明面材之透光部的光並無法充分硬化。所以,從顯示元 件的側邊施行光照射。 光較佳係紫外線、或45〇nm以下的可見光。特別係當在 透明面材上設有抗反射層,且抗反射層或已形成抗反射層 的透月树月曰溥膜、或者在該抗反射薄膜與透明面材間設有 黏著層等紫外線無法穿透的情況,便必須利用可見光進行 硬化。 從側邊進行光照射的光源,係可使用當採取從透明面 材側進行光照射時所使用的光源,但就光源的配置空間、 與適用於特定地方的有效率光照射之觀點,較佳係使用紫 外線、或發出450nm以下之可見光的lED。 光照射的步驟係可在從透明面材一側施行光照射之後 再從側邊施行光照射,亦可相反,或同時施行光照射,為 能更加促進遮光印刷部的未硬化密封部與樹脂層形成用光 硬化性樹脂組成物的光硬化,較佳係先從側邊施行光照 射、或與側邊同時從透明面材側施行光照射。又,當經光 45 201210812 照射後經時會進行樹脂層形成用光硬化性樹脂組成物的硬 化等情況時、或者光硬化性樹脂組成物的硬化需要時間等 情況時,亦可在樹脂層形成用光硬化性樹脂組成物的硬化 大致完成後,再利用從側邊的光照射而使密封部硬化。 [具體例] 本實施形態的製造方法中,第i面材係可任意使用背面 材、或使用表面材。所以,顯示裝置係配合第丨面材的選擇, 可分別依照以下2種方法進行製造。 (α-l)第1面材係使用顯示元件(背面材),第2面材係使 用成為保護板的透明面材(表面材)之方法。 U-2)第1面材係使用成為保護板的透明面材(表面 材)’第2面材係使用顯示元件(背面材)的方法。 以下’以方法U-1)的情况為例,針對^圖的顯示裝 置之製造方法’使用圖式進行具體策明。 (步驟(a)) 如第3圖與第4圖所示,沿顯示元件5〇(第i面材)的周緣 部,利用分配器(未圖示)等塗佈密封部形成用光硬化性樹脂 組成物,而形成未硬化密封部12。 在顯示元件的外周部設置有傳遞用以使顯示元件啟動 之電氣信躺FPC等配輯件。本實闕㈣製造方法中, 當保持各面㈣,就使崎構件•魏絲易之觀點, 最好將顯示元件當作第1面材並配置於下側。 (步驟(b)) 接著,如第5圖及第6圖所示,對由顯示元物的未硬 46 201210812 化密封部12所包圍矩形狀區域13供應樹脂層形成用光硬化 性樹脂組成物14。樹脂層形成用光硬化性樹脂組成物14的 供應里係預先§史疋為由未硬化密封部12與顯示元件及透 明面材10(參照第7圖)所密閉的空間,剛好能利用樹脂層形 成用光硬化性樹脂組成物14填滿的量。 樹脂層形成用光硬化性樹脂組成物14的供應係如第5 圖及第6圖所示’將顯示元件50平放於下定盤18上,利用在 水平方向移動的分配器20,呈線狀、帶狀或點狀供應樹脂 層形成用光硬化性樹脂組成物14而實施。 分配器20係利用由一對導螺22、及與導螺22呈正交的 導螺24所構成之公知水平移動機構,可在區域13的全範圍 中進行水平移動。另外’亦可取代分配器2〇,改為使用模 具塗佈機。 (步驟(c)) 接著,如第7圖所示’將顯示元件5〇與透明面材1〇(第2 面材)搬入減壓裝置26内。在減壓裝置26内的上部,配置有 具備複數吸附墊32的上定盤3〇,並在下部設置有下定盤 31。上定盤30係利用氣缸34可於上下方向移動。 透明面材10係安震於吸附墊32上。顯示元件50係將被 供應樹脂層形成用光硬化性樹脂組成物14之面朝上,固定 於下定盤31之上。 接著,利用真空泵28抽吸減壓裝置26内的空氣。減壓 裝置26内的環境壓力係在到達例如i5〜4〇pa減壓環境之 後,便在將透明面材1 〇利用上定盤的吸附整32進行吸附 47 201210812 保持的狀態下,朝向下方呈待機的顯示元件50 ’使氣缸34 啟動而下降。然後,使顯示元件50與透明面材10隔著未硬 化密封部12相重疊,而構成層積前驅體’並在減壓環境下 保持層積前驅體既定時間。 另外,顯示元件50對下定盤31的安裝位置、吸附墊32 的個數、以及透明面材10對上定盤30的安裝位置等’係配 合顯示元件50及透明面材1〇的尺寸、形狀等而適當調整。 此時,吸附墊係使用靜電吸盤,藉由採用日本特願 2008-206124所附說明書(納入本說明書中)所記載的靜電吸 盤保持方法,可將玻璃基板安定地保持於減壓環境下。 (步驟(d)) 接著,將減壓裝置26的内部形成例如大氣壓之後,便 從減壓裝置26取出層積前驅體。若將層積前驅體放置於大 氣壓環境下,層積前驅體之顯示元件50側的表面與透明面 材1 〇側的表面便利用大氣壓而被按押,而密閉空間内的樹 脂層形成用光硬化性樹脂組成物14則被顯示元件50與透明 面材10加壓。利用該壓力,密閉空間内的樹脂層形成用光 硬化性樹脂組成物I4會流動,密閉空間整體便由樹脂層形 成用光硬化性樹脂組成物M均勻地填充。 胸接著在透明面材上&置遮光印刷部’當使由遮光印 Π所挾持的未硬化密封部與樹月旨層形成用光硬化性樹脂 邊:先行硬化時,便如第8圖所示,從層積前驅體的側 光印刷部55及顯示元件5g所包夾的未硬化密封 祕脂層形成用光硬化性樹脂纽成物14’涵蓋顯示元 48 201210812 件全周施行光(紫外線、或450nm以下的可見光)照射,且從 透明面材10之側’透過透光部56對樹脂層形成用光硬化性 樹脂組成物14施行光(紫外線、或450nm以下的可見光)照 射,而使層積前驅體内部的未硬化密封部12及樹脂層升》成 用光硬化性樹脂組成物14進行硬化,便製得顯示裝置i。 當透明面材上無設置遮光印刷部的情況,便從透明面 材10之側涵蓋層積前驅體全面施行光照射,藉由使層積前 驅體内部的未硬化密封部12及樹脂層形成用光硬化性樹脂 組成物14進行硬化,便製得顯示裝置1。 以上’,?尤方法(a _ 1)的情況為例,針對本實施形態的顯 示裝置之製造方法進行具體說明’而其他方法(α _2)的情況 亦同樣的可製造顯示裝置。 [作用效果:顯示裝置之製造方法] 根據以上所說明本實施形態的顯示裝置之製造方法, 可在樹脂層中不會產生氣泡的情況下,製造大面積的顯示 裝置。假設即便在減壓下施行密封的樹脂層形成用光硬化 性樹脂組成物中有氣泡殘存,對硬化前在高壓力環境下已 密封的樹脂層形成用光硬化性樹脂組成物施加該壓力,便 可減少該氣泡的體積,俾使氣泡容易消失。例如在lOOPa 下已密封的樹脂層形成用光硬化性樹脂組成物中,氣泡中 的氣體體積可認為係在lOOkPa下的1/1000。因為氣體亦會 溶解於樹脂層形成用光硬化性樹脂組成物中,因而微小體 積氣泡中的氣體會迅速溶解於樹脂層形成用光硬化性樹脂 組成物中並消失。 49 201210812 再者,因為即便對密封後的樹脂層形成用光硬化性樹 脂組成物施加大氣壓等壓力,液狀樹脂層形成用光硬化性 樹脂組成物仍屬於流動性的組成物,因而該壓力係均勻分 佈在顯示元件的表面上,不會對接觸到樹脂層形成用光硬 化性樹脂組成物的顯示元件表面其中一部分施加在此以上 的應力,對顯示元件造成損傷的威脅較低。 再者’由樹脂層形成用光硬化性樹脂組成物的硬化所 形成之樹脂層、與顯示元件、透明面材間之界面接著力, 局於利用熱溶接所產生的界面接著力。且,對流動性樹脂 層形成用光硬化性樹脂組成物加壓而密接於顯示元件、透 明面材的表面上’並使在此狀態下硬化,因而可獲得更高 的界面接著力’且可獲得對顯示元件、透明面材的表面呈 均勻的接著’界面接著力局部性降低的情況很少。 所以,在樹脂層的表面發生剝離的可能性低,且從界 面接著力不足的部分滲入水分、腐蝕性氣體的可能性亦較 低。 再者’相較於在2片面材間的狹窄且寬廣面積空間中注 入流動性樹脂層形成用光硬化性樹脂組成物的方法(注入 法)氣泡的產生少,且可在短時間内便填充樹脂層形成用光 硬化性樹脂組成物。且,樹脂層形成用光硬化性樹脂組成 物的黏度限制較少’可輕易地填充高黏度的樹脂層形成用 光硬化性樹脂組成物。所以,可使用含有可提高樹脂層強 度之高分子量硬化性化合物的高黏度樹脂層形成用光硬化 性樹脂組成物。 50 201210812 再者’樹脂層形成用光硬化性樹脂組成物的光聚合起 始劑(C2) ’係使用所具有的吸收波長區域(λ2)較未硬化密封 部的光聚合起始劑(C1)之吸收波長區域(λ1)更靠長波長側 存在的光聚合起始劑(C2),且從層積前驅體的側邊方所照 射之光,係使用吸收波長區域(λ1)内的波長光與吸收波長區 域(λ2)内的波長光二者,藉此,便可使不會被未硬化密封部 的光聚合起始劑(C1)所吸收之吸收波長區域以2)内的波長 光’充分到達由遮光部中顯示元件所包夾的樹脂層形成用 光硬化性樹脂組成物,利用具有吸收波長區域(λ2)的光聚合 起始劑(C2),便可充分地執行樹脂層形成用光硬化性樹脂 組成物的硬化。 [作用效果:硬化性樹脂組成物] 顯示元件與透明面材間之接合上,藉由降低硬化性樹 脂硬化時的收縮率、或降低硬化後的樹脂層彈性模數,便 可降低對顯示元件所施加的應力’而有效地防止顯示斑等 會損及顯示品質的情況發生。 但是,若為降低硬化時的收縮,而增加硬化性化合物 每個硬化部位的分子量,則硬化性化合物的黏性便會變 大,導致硬化性樹脂組成物對面材面的均勻供應趨於困 難,會有硬化時的硬化反應呈不均勻之可能性。 再者,若為降低硬化後的樹脂層的彈性模數,而使含有 對硬化無具貢獻的非硬化性成分,則在未硬化時,硬化性樹 脂組成物的相溶性會降低,導致損及硬化後的樹脂組成物之 透明性,或造成硬化後的樹脂層與面材面間之密接性降低, 51 201210812 亦會有造成表面材與背面材經時剝離的可能性。 相對於此,本發明的硬化性樹脂組成物係特別含有 10〜90質量%之每1分子中具有〇 8〜3個羥基的非硬化性寡聚 物,作為在硬化時不會與樹脂層形成用光硬化性樹脂組成 物中的硬化性化合物(II)進行硬化反應之非硬化性成分,同 時使硬化性化合物(II)中存在有硬化時不會產生反應的羥 基,藉此,便可使未硬化時的樹脂層形成用光硬化性樹脂 組成物之安定性呈良好,俾可降低黏性,且硬化時的硬化 反應均勻性良好,並可降低硬化時的收縮,且可降低硬化 後的樹脂之彈性模數。 若硬化時的收縮降低、硬化後的樹脂之彈性模數降 低,則樹脂層因硬化收縮所產生的應力便會降低。若未硬 化時的樹脂層形成用光硬化性樹脂組成物安定性良好,且 硬化時的硬化反應均勻性良好,便可輕易地獲得透明性良 好的樹脂層。若降低未硬化時的樹脂層形成用光硬化性樹 脂組成物之黏性,便可㈣地充分抑職泡產生,俾可輕 易地獲得面材與樹脂層間之良好界面接合力。 特別係當顯示元件係液晶顯示元件,甚至是 IPS(In-plane Switching,平面杻轉)式液晶顯示元件、或於 顯示面上經貼合視纽善的光學膜之ΤΝ(ΤΜ_价_〇 式液晶顯示元件的情況,因為對顯示元件所施加的應力容 易對顯示品質造成不良影響,gj而接合義層最好係屬於 低彈性模數。 所以,使用本發明硬化性樹脂組成物的顯示裝置中的 52 201210812 顯不元件’較佳係液晶顯示元件,更佳係IPS式液晶顯示元 件、或TN式液晶顯示元件。 另外’本發明的硬化性樹脂組成物並不僅偈限使用於 顯不褒置’亦可適用於一對面材隔著樹脂層進行層積的層 積體’可獲得同樣的效果。 再者’本發明的硬化性樹脂組成物係可為熱硬化性的 樹脂組成物,此情況,硬化性化合物的硬化性基係使用公 知的熱硬化性基。又,視需要使之含有公知的熱聚合起始 劑。上述實施形態中’當樹脂層形成用硬化性樹脂組成物 係屬於熱硬化性的情況,最好亦使密封部形成用硬化性樹 脂組成物為熱硬化性。 特別係因為光硬化性的樹脂組成物在硬化時並不需要 高溫,因而就因高溫而對面材等造成不良影響的威脅較少 之觀點’係屬較佳。 併用光聚合起始劑與熱聚合起始劑等情況,可同時施 行光硬化與熱硬化,或者亦可個別進行提高硬化性。 再者,使用本發明硬化性樹脂組成物製造層積體的方 法,並不僅侷限於上述實施形態的方法,亦玎適當使用公 知方法。 [實施例] 以下,例示為確認本發明有效性而實施的例子。例 1〜5、9及10係實施例,例6〜8係比較例。 (儲存剪切彈性模數、及其損失正切的測定方法) 硬化後的樹脂層之儲存剪切彈性模數及其損失正切 53 201210812 (tan (5 ),係使用流變儀(Anton Paar公司製,Physica

脂層形成用光硬化性樹脂組成物D在25°C下的黏度,結果為 1.3Pa · s。 另外’樹脂層形成用光硬化性樹脂組成物D所使用的光 聚合起始劑(前述IRGACURE 819),係較密封部形成用光硬 化性樹脂組成物C所使用光聚合起始劑(前述IRGACURE 184)的吸收波長區域(約38〇nm以下),更靠長波長側亦具有 吸收波長區域(約440nm以下)。 接著’使用流變儀’測定樹脂層形成用光硬化性樹脂 組成物D光硬化後的黏彈性特性,結果儲存剪切彈性模數係 3.7xl03Pa、其損失正切(tan5)係0.61。 (步驟(a)) 涵蓋顯示元件A的影像顯示區域外側約3mm位置全 周,依成為寬約1mm、塗佈厚度約〇 6mm的方式,利用分 57 201210812 配器塗佈密封部形成用光硬化性樹脂組成物c,而形成未硬 化密封部。 (步驟(b)) 在顯示元件A的影像顯示區域外周所塗佈之未硬化密

The invention relates to a curable resin composition which is suitable for surface material joining, a laminate in which a surface material is laminated using the curable resin composition, And a method of manufacturing the laminate. BACKGROUND OF THE INVENTION In a display device in which a protective layer is laminated on a display element via a bonding resin layer, when the bonding resin layer is cured, stress generated by shrinkage of the bonding resin layer may affect the display element. If stress is applied to the display element, the following problems occur. • The display forming material (hereinafter referred to as the "display material") in the display element is affected by stress, which may impair the uniformity of display. For example, in the case of the liquid crystal display element, the arrangement of the liquid crystal enclosed in the display element is disturbed by the external stress, and the display spot is observed. • When an optical film such as a viewing angle is used to improve the display quality on the surface of the substrate on the display surface side of the display element, the optical characteristics of the optical film may be locally changed due to stress, and the display may be damaged. Uniform sentence / Sexuality. Further, since the bonding resin layer is provided on the inspection side of the display element, if bubbles are present in the cured bonding resin layer, the following problem occurs. • The outgoing or reflected light from the display element will be messy due to air bubbles, which will greatly damage the quality of the displayed image. 3 201210812 Because it remains through the protective plate. • When the display element does not display an image, there is a possibility that the bubbles in the bonding resin layer are more easily detected and the quality of the product. • The interfacial force between the resin layer and the (4) component, and the interface between the lyophilized layer and the slab are reduced. - A method of manufacturing a laminated structure display device having a transparent face material laminated on a display element is known, and a method as described below is known. (1) After injecting a liquid raw material into a resin-made blank plate to harden (4) the bonded resin, or after attaching the rolled-shaped bonding resin to the resin protective plate in a degassed state, the liquid crystal cell is pressed from the end. - Polyoxygen gel (Patent Document 1) is used for the replenishment in the degassing state and in the layer (4) method. (2) At the position of the glass protective plate, the liquid crystal resin is injected under reduced pressure in the space formed between the protective plate and the display panel after the member is positioned and temporarily fixed by the member. The method of laminating the material and hardening it. The liquid resin material is preferably a polyoxyn resin (Patent Document 2). CITATION LIST Patent Literature PATENT DOCUMENT PATENT DOCUMENT PATENT DOCUMENT PATENT DOCUMENT PATENT DOCUMENT PATENT DOCUMENT PATENT DOCUMENT PATENT DOCUMENT PATENT DOCUMENT PATENT DOCUMENT It has been found that the elastic modulus of the bonding resin layer can be lowered by lowering the polarity and molecular weight of the resin layer forming the bonding resin layer. When the elastic modulus of the bonding resin layer interposed between the display element and the Japanese (four) material is lowered, the stress generated during the hardening and contraction is reduced, and the influence on the display quality can be suppressed. However, depending on the reduction of the elastic modulus of the # resin layer, there is a case where the display element and the transparent surface material are not fixed. For example, when the display device is vertically disposed, the display tree may have a time. The possibility of being deflected off or detached from the transparent face material. In addition, it is considered that a high molecular weight hardening precursor compound is used as much as possible in the raw material of the bonding resin layer, and the number of bonding sites of the curing reaction is relatively decreased, whereby the elastic modulus of the bonding resin layer is lowered. The viscosity of the composition when it is not hardened becomes too high and there is a fear that it is difficult to inject or coat. Further, if the crosslink density of the resin layer after hardening becomes too small due to the decrease in the number of bonding sites, the force of fixing the display element and the transparent face material will become insufficient, for example, when the display device is set to #直设置❹, The display element may have the possibility of being deflected off or detached from the transparent face material over time. The present invention has been made in view of the above circumstances, and it is an object of the invention to provide a surface layer which can be sufficiently fixed to each other when a surface layer is integrated by a resin layer composed of a cured product of a curable resin composition. Further, a curable resin composition which can reduce stress caused by shrinkage during curing of the resin layer and a laminate in which the surface material is laminated using the curable resin composition can be used. In addition, it is an object of the present invention to provide a surface layer which is formed by laminating a surface layer of a cured resin formed of a curable resin group 201210812, and the surface materials can be sufficiently fixed to each other. A method for producing a laminate in which the stress generated by the shrinkage of the resin layer is reduced and the generation of bubbles in the resin material is sufficiently suppressed. The means for solving the problem of the present invention is a laminate for use in a laminate in which a uncured curable resin composition is held between a pair of face materials and cured. The surface material is at least a surface material which is transparent, and the curable resin composition contains the following curable compound (II) and the following non-curable oligomer (D), and the non-hardening property The content of the oligomer (D) is 10 to 90% by mass. The curable compound (II) is one or more types of a curable compound which undergoes a curing reaction when the curable resin composition is cured, and at least one of the curable compounds One type has a radical which does not react when the curable resin composition is cured. Non-curable polymer (D): an oligomer which does not undergo a curing reaction with the curable compound (II) when the curable resin composition is cured, and has 0.8 to 3 hydroxyl groups per molecule. It is preferred that the curable compound (II) contains a monomer having a curable group and having a hydroxyl group. Preferably, the curable compound (II) contains an oligomer (A') having a curable group and having a molecular weight of 1,000 to 100,000; and a monomer (B〇 having a curable group and having a molecular weight of 125 〜) 600, and the monomer (B,) contains a monomer having a hydroxyl group (B3). 201210812 The second is a non-hardening oligomer (D), and the polyoxygen extension polymer (4) is a polyoxygen extension. An amine-based oligo-polymer synthesized by using a polybasic vinegar as a raw material. The vehicle X is preferably the aforementioned oligomer (A,) having a propyl sulphate and a sulphide (a) Preferably, the monomer (B3) contains a mercaptopropionic acid via a base having a hydroxyl group of 1 and a carbon number of 3 to 8. Preferably, the above is preferred. The monomer (B,) contains a monomer (1) 4) selected from the group consisting of alkyl thioalkyl acrylates having a carbon number of 8 to u. Preferably, the alkane does not contain a chain transfer agent, or contains a chain transfer agent, and is extended in an amount of 100 parts by mass based on 100 parts by mass of the curable compound (11), and the layered body provided by the present invention is contained.

[Surface material] The surface material is a display element that can be penetrated by the display image. Bright surface material 10 201210812 (protective plate). The transparent surface material is, for example, a glass plate or a transparent resin plate, and is highly transparent to the light emitted from the display element and reflected light. From the viewpoints of low birefringence, high planar precision, surface scratch resistance, and high mechanical strength, it is most preferably a glass plate. The viewpoint of sufficiently penetrating light energy for hardening a photocurable resin composition is also The glass plate is preferably a material of the glass plate, for example, a glass material such as soda lime glass, and preferably a high penetration glass having a lower iron content and less blue light (the glass P is used for safety improvement, and the surface material may be A tempered glass is used. The material of the transparent resin sheet is, for example, a resin material having high transparency (such as polycarbonate, polymethyl methacrylate, etc.). In the transparent surface material, in order to enhance the interfacial adhesion between the resin layer and the resin layer, Surface treatment can also be carried out. The method of surface treatment is, for example, a method of treating a surface of a transparent surface material with a broken yard coupling agent, or forming an yttrium oxide by using an oxidizing flame generated by a flame burner. Film treatment, etc. In the transparent surface material, in order to improve the contrast of the display image, an anti-reflection layer may be provided on the back surface of the joint surface with the resin layer. The anti-reflection layer may be formed directly on the surface of the transparent surface material, for example. A method of bonding an inorganic thin film or a method of bonding a transparent resin film provided with an antireflection layer to a transparent surface material is provided. Further, for the purpose of image display, a part or all of the transparent surface material may be colored in advance. Or it is light-scattered, and light is refracted or reflected by the fine unevenness of the surface, etc. Further, 201210812 can also optically optical film, polarizing film, etc. as described above. The modulated optical film or the like is bonded to the transparent surface material to form an integral body, and is used as a transparent surface material. The thickness of the transparent face material is usually 0.5 to 25 mm in terms of mechanical strength and transparency. The use of a television receiver for indoor use, a display for a PC, etc., is preferably 0.7 to 6 mm in terms of weight reduction of the display device, and is preferably 3 to 20 mm when used for outdoor display. Reinforced glass can be used for the transparent surface material, and chemically strengthened glass can be used when the transparent surface material is thin. In the case of a transparent resin sheet, it is preferably 2 to 10 mm. [Back material] The back material is a display element. The display element 50 of the illustrated example is a liquid crystal display in which a transparent surface material 52 provided with a color filter and a transparent surface material 53 provided with a TFT are bonded together and sandwiched by a pair of polarizing plates 51. Although an element is an example, the display element of this embodiment is not limited to the illustration. The display element is a display material in which an optical state is changed by an external electrical signal in a pair of electrodes in which at least one of them is a transparent electrode. Depending on the type of the display material, there are, for example, a liquid crystal display element, an EL display element, a plasma display element, an electronic ink type display element, and the like. Further, the display element has a configuration in which a pair of face materials are bonded and at least one of the pair of face materials is a transparent face material, and the transparent face material side is disposed adjacent to the resin layer. At this time, a part of the display elements are provided on the outermost layer side of the transparent face material on the side adjacent to the resin layer, and an optical film such as a polarizing plate or a phase difference plate is provided. In this case, the resin layer is in a state in which the optical film on the display element is bonded to the surface material. 12 201210812 The surface of the joint between the display element and the resin layer can be surface-treated to enhance the interface between the seal and the seal. The surface treatment can be applied to only the peripheral portion and can also be applied to the entire surface of the face material. The surface treatment method is, for example, a method in which a low-temperature process can be used followed by a primer or the like. The thickness of the display element is usually 0.4 to 4 mm when it is a liquid crystal display element activated by a TFT, and is usually 0. 2 to 3 mm when it belongs to an EL display element. [Resin layer] The resin layer is a layer formed by curing the curable resin composition of the present invention (hereinafter also referred to as "photocurable resin composition for forming a resin layer"). The curable resin composition of the present invention (the photocurable resin composition for forming a resin layer of the present embodiment) can reduce the modulus of elasticity after curing and can reduce the stress generated during curing. Therefore, it is possible to suppress the adverse effect on the display performance of the display element due to the stress. Further, since the curable resin composition has a low viscosity when it is not cured, the curable resin composition on the surface of the surface material can be supplied in a short time, so that it is easy to prevent bubble residue after the surface material and the back material are laminated. situation. The thickness of the resin layer is preferably 0_03 to 2 mm, more preferably 〇.1 to 〇.8 mm, and particularly preferably 0.2 to 0.6 mm. If the thickness of the resin layer is more than mm3 mm, the resin layer can effectively buffer the impact caused by the external force from the side of the transparent surface material. In particular, when the display element is sensitive to external force and is more likely to affect the display quality, it is preferably set to a thickness of 0.2 mm or more. Further, in the production method of the present embodiment, even if a foreign material exceeding the thickness of the resin layer is mixed between the transparent surface material and the display element, the thickness of the resin layer 13 201210812 does not change much, which affects the light penetration performance. less. If the thickness of the resin layer is 2 mm or less, the bubbles are less likely to remain in the resin layer, and the overall thick jersey of the display device will be thicker than W. When the elastic modulus of the fat-receiving layer is small, the time when the display element of the material display element is shifted with time or the like is preferably set to a thickness of 〇6 mm or less. The method of adjusting the thickness of the resin layer is a method of adjusting the thickness of the sealing portion described later and adjusting the supply amount of the liquid-hardening resin composition for forming the liquid resin layer supplied to the second surface material. [Sealing portion] The sealing portion is formed by applying a photocurable resin composition for forming a liquid sealing portion, which is described later, and is cured. Since the outer region of the image display area of the display element is relatively narrow, the width of the sealing portion is preferably narrow. The width of the sealing portion is preferably 0.5 to 2 mm, more preferably ο" to i.6 mm. [Light-shielding printing portion] A light-shielding printing portion can be provided on the peripheral portion of the transparent surface material as needed. The opaque printing unit hides the wiring member or the like connected to the display element so that it cannot be seen from the side of the transparent surface material except for the image display area of the display element. The light-shielding printing portion can be provided on the joint surface of the transparent surface material and the resin layer or the back surface thereof to reduce the parallax between the light-shielding printing portion and the image display region, and is preferably provided on the joint surface of the transparent surface material and the resin layer. In the case where the transparent surface material is a glass plate, it is preferable that the light-shielding printing portion is made of a ceramic printing plate containing a black pigment. The light-shielding printing portion can also be formed by bonding a transparent film having a light-shielding portion on the front surface or the back surface to the transparent surface material. A transparent face material without a light-shielding printing portion can also be used. 201210812 [Shape] The shape of the display device is usually rectangular. The size of the display device is not particularly limited, and the manufacturing method of the present embodiment is particularly suitable for the manufacture of a display device having a large area, and thus it is preferable to use a liquid crystal display element, and in the case of a pc screen, it is preferable ( Umx〇.i8m is preferably 〇 or more, more preferably 〇.7mx 〇.4m or more in the case of a television receiver. The upper limit of the size of the display device is often determined according to the size of the display element. The apparatus tends to be difficult to handle, etc. The upper limit of the size of the display device is usually about 2.5 mxl_5 m from the viewpoint of 鸪, etc. In the case of a small display, it is preferably 0.14 mx 〇. 〇 8 m or more. The transparent face material of the plate and the size of the display element can be substantially equal, but in relation to the other housings accommodating the display device, in most cases, the transparent face material is larger than the display element. The structure of the frame can also make the transparent surface material a little smaller than the display element. <Manufacturing Method of Display Device> The method of manufacturing the display device according to the present embodiment includes the following steps (a) to (d). The surface of the surface of the surface material of the V-shaped surface material (the moon-shaped material (or surface material)) is coated with a photo-curable resin containing a curable compound (I) and a photopolymerization initiator (α). (4) Forming an uncured seal portion (However, when the first face material is a display element, a seal portion is formed on the surface on the image display side). (b) A step of supplying a photocurable resin composition for forming a liquid resin layer containing a curable compound (2012) and a photopolymerization initiator (C2) to the uncured sputum. (c) The second surface material (surface material (or back material)) is superposed on the resin layer-forming photocurable resin composition under a reduced pressure of 100 Pa or less to obtain a photocurable resin for resin layer formation. a step of laminating a precursor having a second surface material, a second surface material, and an unhardened sealing portion (however, when an antireflection film is provided on the surface of the second surface material, the back side is The surface-adjacent resin layer is formed so as to overlap with the photocurable resin composition. In the case of the second surface-material display element, the image display side is superimposed on the photo-curable resin composition for resin layer formation. . (d) A step in which the uncured seal portion and the resin layer-forming photocurable resin composition are irradiated with light to be cured in a pressure environment of 5 kPa or more. When the light-shielding portion is not formed on the transparent surface material, the sealing portion and the resin layer-forming photocurable resin composition are irradiated with light from the laminated surface on the side of the transparent surface material through the light-transmitting portion. When the light shielding portion is formed on the peripheral portion of the transparent surface material, the area of the light transmission portion surrounded by the light shielding portion is smaller than the area of the resin layer surrounded by the sealing portion, and the resin layer is formed of a photocurable resin. The absorption wavelength region (12) of the photopolymerization initiator (C2) contained in the product is higher than the absorption wavelength region of the photopolymerization initiator (Ci) contained in the photocurable resin composition for sealing portion formation. (λ 1) exists on the longer wavelength side, and the light irradiated from the side of the laminated precursor in the above step (d) covers the wavelength light and the absorption wavelength region in the absorption wavelength region (λ 1 ) ( Also 2) wavelength light inside. 16 201210812 The manufacturing method of the present embodiment is a photocurable resin composition for forming a liquid resin layer between the second surface material and the second surface material in a reduced pressure environment, and a high pressure environment in an atmospheric pressure environment. Next, a method of forming a resin layer by curing the resin layer formed by curing the formed photocurable resin composition (decompression lamination method). The method of encapsulating the photocurable resin composition for forming a resin layer under reduced pressure is not a method of injecting a photocurable resin for forming a resin layer in a narrow space between the first surface material and the second surface material. The photocurable resin composition for forming a resin layer is supplied to almost the entire surface of the second surface material, and then the second surface material is superposed on the surface of the first surface material and the second surface material. A method of resin composition. An example of a method for producing a transparent laminate by encapsulating a photocurable resin composition for forming a liquid resin layer under reduced pressure and curing the photocurable resin composition for forming a resin layer under atmospheric pressure known. For example, the method for producing a transparent laminate described in the pamphlet of International Publication No. WO 2008/81838, the pamphlet of International Publication No. 2009/16943, and the photocurable resin composition used in the production method are incorporated in the present specification. [Step (4)] First, an uncured seal portion is formed along the peripheral portion of the surface of the first face material. The first surface material can be used arbitrarily as a back material or a surface material. When the first surface material belongs to a transparent surface material which is a protective sheet for a display element, the surface on which the uncured seal portion is formed can be arbitrarily one of two surfaces. When the characteristics of the two surfaces are different, the desired surface is selected. For example, when one of the surfaces has a surface treatment of the interface between the resin layer and the resin layer, the uncured seal is formed on the surface. Further, in the case where the roll is provided with an antireflection layer on one of the surfaces, an unhardened seal portion is formed on the back surface. In the case of the first surface material display element, the surface on which the uncured seal portion is formed is the surface on the image display side. The uncured seal portion is characterized in that, in the step (C) to be described later, the photocurable resin composition for forming a night-like resin layer does not have an interface between the unhardened seal portion and the first face material, and an unhardened seal. The interface between the portion and the second surface material has an interface adhesion force of more than the extent of the leakage and a degree of robustness capable of maintaining the shape. Therefore, it is preferable that the uncured seal portion is formed of a photocurable resin composition having a high viscosity and formed by coating such as printing or arranging. In addition, in order to maintain the space between the first surface material and the second surface material, it is also possible to form a photocurable resin for the sealing portion, and the spacer particles are formed of a photocurable resin for forming a sealing portion. Immediately after application, the sealing portion may be partially semi-cured by irradiating light for curing the sealing portion, and the shape of the sealing portion may be maintained for a longer period of time. [Photocurable resin composition for sealing portion formation] The photocurable resin composition for sealing portion formation (hereinafter also referred to as "sealing material") is a photocurable curable compound (1) and a photopolymerization initiator (C1). Liquid composition. The viscosity of the photocurable resin composition for forming the sealing portion is preferably 500 to 3 Pa·s, more preferably 2 to 2,500 Pa·s, and more preferably 1 to 12,108,028,200 Pa·s. When the viscosity is 500 Pa·s or more, the shape of the uncured seal portion can be maintained for a long period of time, and the height of the seal portion can be sufficiently maintained. If the viscosity is at 3000Pa.  Below s, the sealing portion can be formed by a coating method. The viscosity of the photocurable resin composition for forming the seal portion was measured at 25 Å using an E-type viscometer. (The curable compound (I)) The curable compound (1) is preferably one in which the viscosity of the photocurable resin composition for forming a sealing portion is adjusted within the above range, and it is preferable to contain the oligo (4) or more. More than or equal to the monomer (9), the oligomer (4) has a curable group and has a number average molecular weight of 3 Å to 1 Å; the monomer (B) has a curable group and a molecular weight of丨25~6〇〇. The curable group of the polymer (A) or the monomer (B) may, for example, be an unsaturated group having an addition polymerizable group (such as a propylene fluorenyl group, a decyl propylene oxy group or the like) and a thiol group. From the viewpoint of the combination of the groups and the like, the viewpoint of the fast curing rate and the transparency to the sealing portion can be obtained, and is preferably selected from the group consisting of a acryloxy group and a mercapto acryloxy group. The curable group in the monomer and the curable group in the monomer (B) may be the same or different from each other. Because of the hardening group in the oligomer having a relatively high molecular weight, the reactivity tends to become lower than The hardening group in the monomer (B) having a relatively low molecular weight, and thus the hardening of the monomer (B) proceeds first, resulting in an increase in the viscosity of the entire composition, resulting in an inhomogeneity of the hardening reaction. The reactivity of the hardening group is poor, and a homogeneous sealing portion can be obtained, and the hardening group in the oligomer (A) is preferably a highly reactive propylene oxy group, and the monomer (B) is used. The hardening group in the middle is set to a less reactive methyl group 201210812 propylene oxime. The number average molecular weight of the oligomer (A) 30000 to 100000, preferably 40,000 to 80,000, more preferably 50,000 to 65,000. If the number average molecular weight of the oligomer (A) is within this range, the sealing portion is easily formed into a photocurable resin composition. The viscosity is adjusted within the above range. The number average molecular weight of the oligomer (A) is obtained by Gpc measurement, and is a polystyrene-converted number average molecular weight. In addition, in the Gpc measurement, 'when there is a low molecular weight component which is unreacted by ib When the peak of (monomer or the like) is sharp, the peak is excluded from the number average molecular weight. The molecular weight of the monomer (B) is 125 to _, preferably 14 〇 to 4 Å, more preferably 150 to 350. When the molecular weight of the body (B) is 125 or more, when the display device is produced by the pressure reduction lamination method described later, volatilization of the monomer (9) can be suppressed. If the monomer (_ molecule 4 is in the _ town, the monomer can be increased) Polymer .  The solubility of the oligomer (4) can be appropriately adjusted, and the viscosity of the (four)-shaped resin-based resin composition can be appropriately adjusted. (Oligomer (A)) The oligomer (4) is preferably an average of 1. per molecule for the viewpoint of the curability of the photocurable resin composition for forming a sealing portion and the mechanical properties of the sealing portion. 8 to 4 hardening bases. The oligomer (A) may, for example, be a urethane condensate having an amine phthalate linkage, a poly(methyl) acrylate vinegar of a polyoxyl extension polyol, or a polyphenol polyol. β (meth) acrylate, etc. According to the molecular design of the carboxylic acid smelting chain, it is possible to broadly adjust the viewpoints such as the simplicity of the tree after hardening (4) and the adhesion to the ton, 20 201210812 The urethane sulfonate oligomer (A1) which is synthesized by using polyisocyanide as a raw material is more preferably a urethane oligomer (A1) which will be described later. The polyhydric alcohol is preferably a polyoxyalkylene-based polyol. (Amine phthalate polymer (A1)) The urethane oligomer (Al) 'g' having a number average molecular weight of 3 〇〇〇〇 to 1 〇〇〇〇〇 is highly degraded. It is difficult to carry out the mixing with the monomer because it is difficult to perform the synthesis according to the ordinary method, even if it can be synthesized. Therefore, it is preferred to use the obtained product as a seal after synthesizing the amine-method (A1) according to the synthesis method using the monomer (B) (the following monomers (B1) and (B2)). The photo-curable tree residue is formed in the portion, or the obtained product is further diluted with the monomer (B) (the following monomer (B1), monomer (B3), etc.) to be used as a sealing portion.

The polyhydric alcohol and the polyisocyanate are known compounds, and are, for example, a polyterpene alcohol (1), a diisocyanate (..., etc.) which is a raw material of an amine phthalate oligomer (& 21,108,108) described in the pamphlet of International Publication No. 2009/016943. The polyhydric alcohol (1) may be a polyoxyalkylene-based polyol such as polyoxyethylene glycol or polyoxypropylene propylene glycol; a poly-polyol or a polycarbonate polyol. Among them, 'preferably polyoxyl extension-based polyol, more preferably polyoxy-extension propyl polyol. Also, if the oxygen extension of the polyoxypropyl propylene glycol is partially substituted with oxygen extension Ethyl' is preferable because it can improve the compatibility of the photocurable composition for forming a resin layer with other components. Here, "the so-called "some of the oxygen-extended propyl group can be substituted with an oxygen-extended ethyl group".

Specifically, for example, a hydroxyalkyl (meth) acrylate having a hydroxyalkyl group having 2 to 6 carbon atoms (such as 2-hydroxymethyl (meth) acrylate or (fluorenyl) acrylate-2- Hydroxypropyl ester, 2-hydroxybutyl (meth)acrylate, 4-hydroxybutyl (meth)acrylate, etc., etc., preferably a hydroxyalkyl acrylate having a hydroxyalkyl group having 2 to 4 carbon atoms (Monomer (8)) The monomer (B) is preferably one to three hardening groups per molecule from the viewpoints of the curability of the photocurable resin composition for forming a sealing portion, the mechanical properties of the sealing portion, and the like.

When the short-wavelength visible light is used for hardening, the photopolymerization of the Lithium-based phosphine oxide system starts from the viewpoint of absorbing the wavelength region. By using two or more kinds of photopolymerization initiators (C1) having different absorption wavelength regions in combination, the hardening time can be further accelerated or the surface hardenability of the sealing portion can be improved. In addition, when the transparent surface material is provided with a light-shielding printing portion, and the light is irradiated from the side surface of the surface material, the uncured seal portion held by the light-shielding portion and the photo-curable resin composition for resin layer formation are used. In the case of hardening, it is possible to use a photopolymerization initiator (C2) which will be described later in the range of curing of the resin layer-forming photocurable resin composition which does not inhibit the adjacent portion of the uncured seal portion. The ratio of the polymerization initiator (C1) to the polymerization initiator (C2) is preferably 5 Å in terms of the mass ratio of (C1):(C2) in terms of efficiency and effective hardening. Bu 5: i. In order to allow the resin layer-shaped graded tree (4) to be held by the light-shielding printing portion, the light irradiated from the side surface of the surface material can be hardened in a short time via the uncured sealing material, and the photocurable resin for forming the sealing portion can be formed.

In particular, since the amount of the polymerization terminator is less than that of the polymerization initiator, the stability of the photocurable resin composition for the seal portion can be improved, and the molecular layer of the hardened tree layer can be adjusted. When the sealing material is hardened by light irradiated from the side surface of the face material, such as a polymerization terminator, a chain transfer agent, a light stabilizer, a pigment, (4), etc., which have an effect of delaying the hardening reaction, it is preferable not to use as much as possible.

In the case of the light-curable resin composition of the photo-curable resin, the formation of the light-curable resin composition is less than (4). Therefore, the amount is preferably such that the resin layer is increased by 7 to the thickness of the photocurable resin composition, and a certain amount is thicker than the thickness of the resin layer. In the case where the hardening shrinkage is small, the predetermined thickness of the resin layer and the thickness of the photocurable resin composition for forming a resin layer may be made substantially equal.

Further, since the low boiling point component is small, it is suitable for the pressure reduction lamination method to be described later. When the viscosity is 50 Pa·s or less, the resin layer is less likely to have bubbles remaining. The viscosity of the photocurable resin composition for resin layer formation was measured at 25 ° C using an E-type viscometer.

When the curable compound (π) contains the compound (na), a hydroxyl group is present in the cured product in which the curable compound (II) is hardened alone. The presence of the warp group contributes to the stabilization of the non-curable oligomer in the photocurable resin composition for forming a resin layer. Therefore, the compound (Ila) having the hydroxyl group which does not react at the time of hardening may be any unreacted hydroxyl group after the hardening reaction, for example, even if a part of the hydroxyl group of the compound (Ila) is hardened, the other part is not hardened. It can be left in an unreacted state. The compound (IIa) having a hydroxyl group which does not react upon curing may be an oligomer having a repeating unit as long as it has a curable group which contributes to the hardening reaction and has a hydroxyl group. .

The curable group in the nutrient (A') and the curable group in the monomer (B') may be the same or different from each other. Because of the hardening group of the higher molecular weight polymer (A,), the reactivity is more likely to become lower than the hardening group of the lower molecular weight monomer (B,), and thus the hardening of the monomer (B,) When it is carried out first, the viscosity of the entire composition is rapidly increased, and there is a possibility that the hardening reaction is inhomogeneous.

The content ratio of the right monomer (B3) is 6 〇 mass% or less. The hardness of the cured product composed of the photocurable resin composition for forming a resin layer is not excessively high, and is preferable. The monomer (B') is preferably a mechanical property of the resin layer. The monomer (B4) is contained. Since the monomer (B4) lowers the glass transition temperature (Tg) of the resin layer after hardening, it contributes to a decrease in the elastic modulus of the resin layer after hardening, and the resin can be improved. The softness of the layer. However, when the curing property of the photocurable resin composition for forming a resin layer is increased and the time required for curing is shortened, it is preferable to reduce the content of the monomer (B4) or not. Monomer (B4): one or more selected from the group consisting of alkyl methacrylates having a carbon number of 8 to 22. If the carbon number is 8 or more, the glass transition temperature of the cured product can be lowered, which is preferable.

When the content of the monomer (7) is 5% by mass or more, the sufficient addition effect of the monomer (B4) can be easily obtained (photopolymerization initiator (C2)). The resin composition for forming a resin layer is used in the photocurable resin composition.

(Non-curing oligomer (D)) The non-curable oligomer (D) is excellent in compatibility with the photocurable resin composition for forming a resin layer and does not contribute to hardening, so that it can be prevented from being damaged. In the case of transparency and homogeneity, the stress generated by shrinkage at the time of hardening of the layer is reduced. When the non-curable oligomer is cured by the photocurable resin composition for forming a resin layer, it does not undergo a curing reaction with the curable compound (11) in the composition, and has 8 to 3 hydroxyl groups per molecule.

If the hydroxyl group per molecule is up to 〇. 8 or more, between the non-curable polymer, or between the non-curable oligomer and the cured product obtained from the curable compound (II), the non-hardening property can be stably maintained by the interaction between the hydroxyl groups. The viewpoint of the oligomer is preferable, and when the number of hydroxyl groups per molecule is three or less, the non-curable oligomer can be suitably dissolved in the photocurable resin composition for forming a resin layer. The system is preferred. The number average molecular weight (?n) of the average of one hydroxyl group of the non-curable oligomer (D) is preferably from 400 to 8,000. When the number average molecular weight of the average number of hydroxyl groups is 400 or more, the polarity of the non-curable oligomer (D) does not become too high, and the curability in the photocurable resin composition for forming a resin layer can be easily obtained.

The aliphatic polyglycol diol.匕Polycarbonate S is a multi-component energy consumption, for example: M•二二料 diol residue of ruthenium aliphatic poly (tetra) diol; or aliphatic cyclic carbonic acid (IV) ring-opening polymer special aliphatic polycarbonate 2 alcohol. And the average molecular weight (?n) of the average number of hydroxyl groups of the ester polyol or the polycarbonate polyol is preferably from 400 to 8000', more preferably from 8 to 6 Å. In the present specification, the number average molecular weight of the non-curable oligomer (D) is a value Α (κ〇Η mg/g) measured according to JIS K1557-1 (20〇7 edition), and non-hardening oligomerization. The number of hydroxyl groups in the molecule (0) 1 is calculated according to the formula of the following 35 201210812 formula u). Molecular weight of the non-curable emulsion (D) = 56 1xBx1 〇〇〇 / a (1) From the viewpoint that the elastic modulus of the resin layer after hardening is likely to be lower, the non-hardening oligo (4) (D) is higher than (4) The oxyperkiol polyol is more preferably a polyoxypropylidene polyol. As described later, in order to adjust the polarity of the non-curable oligomer (9), a part of the oxygen-extended propyl group of the polyoxy-extension propylene polyol may be substituted with an oxygen-extended ethyl group. The oxygen-extended propyl group may also be partially substituted with an oxygen-extended ethyl group, which is the same as described above for the plural. For example, from the viewpoint of compatibility, an oligomer (A) is preferably an amine phthalate oligomer synthesized by using a polyoxyalkylene polyol and a polyisocyanate as a raw material, instead of a curable oligomer. (D) is a polyoxyalkylene polyol. In the present invention, in order to stabilize the photocurable resin composition for forming a resin layer when it is not cured, it is preferable to suppress the non-curable oligomer (D) from being cut away from the hardened layer of the tree layer. The polymer (A') has a molecular bond of the same structure or a similar structure as the non-curable oligomer (〇). Specifically, in the case of forming the oligomer (A·) in the photocurable resin composition of the synthetic resin layer, it is preferred to use a compound having a hydroxyl group such as a polyhydric alcohol (hereinafter also referred to as "containing a radical". Compound "), and the same trans-containing compound is used as the non-curable oligomer (D). For example, when the oligomer (A') is a urethane oligomer synthesized using a polyoxyalkylene polyol and a polyisocyanate as a raw material, it is preferred to use the polyoxyalkylene polyol as Non-hardening oligomer (D). Or, when the hydroxyl group-containing compound used as the raw material of the oligomer (A') and the hydroxyl group-containing compound used as the non-curable oligomer (D) are not the same, it is preferable that the two molecules are The chain has a common repeating unit or the like, and the partiality has a common structure' and the polarities of the two are set to the same extent. The method of adjusting the polarity is, for example, a method of increasing the enthalpy by introducing a sulfhydryl group, by stretching the propyl group by oxygen. The p-knife is a method of increasing the polarity by substitution with an oxygen-extended ethyl group, and a method of increasing the polarity by the molecular weight of the lower-lying group. These methods can also be used in combination. For example, the valence polymer (A) is a polyoxyl propyl poly(tetra) (a), which is substituted with an oxygen-extended ethyl group, and a poly-isocyanate, which is synthesized by using a raw material. In the case of the filaria, it is preferred to use a polyoxy-extension propylene polyol having no oxygen-extended ethyl group as the non-curable polymer (D), and the average molecular weight of one base is 切_(a,) The wire stretches propyl polyol. The photocurable resin composition for forming an optimum resin layer is exemplified by a composition of the following oligomer (A·), non-curable oligomer (D), and body (Β·). The polymer (Α,) is a polyoxypropyl propylene glycol in which a part of the oxygen-extended propyl group has been substituted with an oxygen-extended ethyl group, and reacted with a polyisocyanate compound to obtain a prepolymer having an isocyanate group, and The monomer (Β2) is reacted to obtain an amine formate oligomer (Α2); the non-hardening oligomer (D) is the same as the raw material of the urethane oligomer (Α2), and the oxygen is extended to C A polyoxyalkylene propylene glycol in which a part of the base has been substituted with an oxygen-extended ethyl group; and the monomer (Β') is a monomer having a hydroxyl group (Β3). According to this, if the oligomer (Α') partially has the same molecular structure as the non-curable oligomer (D), the compatibility of the non-hardening oligomer (D) in the composition can be further improved. Further, by the hydroxyl group of the monomer (Βι), the interaction between the hydroxyl group in the molecular structure of the hardened 37 201210812 compound (II) and the hydroxyl group in the molecular structure of the non-hardening oligomer (D) is judged. The non-hardening oligomer (D) can be stably present in the hardened material. Further, in other examples, a composition containing the oligomer, the non-curable oligomer (D), and the monomer (B') may be used to obtain a non-hardening oligomer in the composition (D). ) is in good compatibility' and allows the non-hardening oligomer (D) to be stably present in the hardened material. The oligomer (A,) is obtained by reacting a polyoxypropyl propylene glycol having a part of an oxygen-extended propyl group with an oxygen-extended ethyl group, and reacting with a polyisocyanate compound to obtain a pre-isocyanate group. An amine phthalate oligomer (A2) obtained by reacting with the aforementioned monomer (B2); the non-hardening oligomer is a polyoxypropylene propylene glycol which is not substituted with an oxygen-extended ethyl group. 'The polyoxypropyl propylene glycol having a molecular weight smaller than the raw material of the urethane acrylate oligomer (A2); and the monomer (B,) is a monomer (B3) having a hydroxyl group. The content of the non-curable oligomer (D) in the photocurable resin composition for forming a fat layer is preferably from 1 to 9 % by mass, more preferably from 3 to 8 % by mass. When the content of the right non-hardening oligomer is 10% by mass or more, the effect of reducing the stress generated by the shrinkage of the resin during hardening can be easily obtained by filling. If it is 90% by mass or less, the face materials can be easily fixed to each other sufficiently, and the temporal positional displacement of the surface material and the back material can be easily and satisfactorily prevented. In the resin layer viscoelasticity measurement after the resin layer forming photocurable resin composition is cured, the storage shear modulus is preferably 5χ1〇2 to lxl〇5pa, more preferably 8x1〇2 to 5xl〇. 4pa, especially good for 1x10~5xl〇4pa. Also, the loss tangent (tan (5) is preferably 1. 4 or less, better 38 201210812 Series 1. 0 or less. The lower limit of the loss tangent is not particularly limited, and can be set to a range that can be achieved in a manufacturing process. When it is a soft resin layer, it is usually 达. 〇 1 or more. Rhyme shear elastic bond and loss tangent (four) method, as detailed later, using a dynamic (four) measuring device to form a photohardenable resin composition for the unhardened tree layer, applying dynamic shear stress And / or a method of hardening the resin composition to harden the resin composition. If the shear modulus after hardening is 1 x l 〇 5 Pa or less, the stress caused by shrinkage of the resin during hardening can be sufficiently reduced, and the influence on the display quality of the display panel can be suppressed. If the shear modulus is up to Μ. More than %, the face material (display element and transparent face material) can be well fixed. Also, if the loss is tangent at 1. 4 or less, even when the display device is used vertically, the display element can be sufficiently fixed to the transparent surface material, and the display element can be prevented from occurring due to plastic deformation of the resin layer due to the own weight of the display element. Position offset. When the photocurable resin composition for forming a resin layer contains non-hardening, the [raw oligomer (D)' can cut the material under the condition that the resin layer loss tangent (1) after the hardening is suppressed The elastic modulus is reduced, so that the respective preferred ranges of storage shear modulus and loss tangent (taM) in the dynamic viscoelasticity measurement can be achieved. (Additive) The photocurable resin composition for forming a resin layer may contain, for example, a polymerization terminator, a photohardening accelerator, a chain transfer agent, a light stabilizer (such as an ultraviolet absorber, a self-based capture agent, etc.). ), an antioxidant, a flame retardant, an adhesion promoter (such as Wei coupling), a pigment, a dye, and the like, each of which has a polymerization terminator or a photoinhibitor. In particular, by using a small amount of a polymerization terminator which is more than a polymerization initiator, it is possible to improve the hardness of the resin layer-shaped fine-light hard-recording group, and also the molecular weight of the resin layer after the hardening. By making a small amount of the chain transfer agent contained, the molecular weight of the resin layer after hardening can be adjusted to decrease the thickness of the resin layer, but in many cases, the hardening rate is slowed down. The photocurable resin composition for forming a resin layer containing a large amount of the non-curable oligomer (D) of the present invention, since the elastic modulus can be adjusted by the content of the oligomer (9), the content of the chain transfer agent can be reduced, or Not included is preferred. Specifically, the amount of the chain transfer agent added is preferably in the range of i parts by mass or less based on 100 parts by mass of the total of the oligomer (A) and the monomer (B'). Better system 0. 5 parts by mass or less. [Step (4)] After the step (b), the first surface material to which the photocurable tree-forming composition for resin layer formation is supplied is placed in a decompression device, and the support plate is fixed in the decompression device. The first face material is placed flat on the side of the curable resin composition. A moving support mechanism that is movable in the vertical direction is provided in an upper portion of the decompression device, and a second surface material is attached to the movable support mechanism. When the second face material is the display element, the surface on the side where the image is displayed faces downward. When the antireflection layer is provided on the surface of the second face material, the surface on which one side of the antireflection layer is not formed faces downward. The second face material is placed above the first face material and is not formed with the resin layer. 40 201210812 The position where the photocurable resin composition is in contact with each other. In other words, the photocurable resin composition for forming a resin layer on the first surface material is opposed to the second surface material without coming into contact with each other. Further, a moving support mechanism that moves in the vertical direction may be provided in a lower portion of the decompression device, and a first face material to which a curable resin composition is supplied may be placed on the moving support mechanism. In this case, the second surface material is attached to the fixed support disk provided on the upper portion of the pressure reducing device, and the first surface material and the second surface material face each other. Further, both the first face material and the second face material may be supported by the upper and lower movement supporting mechanisms provided in the decompression device. After the first face material and the second face material are placed at a predetermined position, the inside of the reduced pressure device is decompressed to form a predetermined reduced pressure environment. If possible, the first face material and the second face material may be placed at a predetermined position in the pressure reducing device after the pressure reduction operation or after the predetermined pressure reduction environment is formed. After the inside of the decompression device is in a predetermined decompression environment, the second face material of the building supported by the shifting and lowering mechanism is moved downward, and the second face material is superposed on the resin layer forming light on the & face material. Above the curable resin composition. By overlapping, the surface of the second surface material (the surface of the second surface material displayed on the display element @ image) (the surface on the side where the image is displayed as the display element) and the uncured surface are not hardened. In the work chamber surrounded by the sealing portion: 'The photocurable composition of the resin layer is sealed. When the overlap is performed, the resin layer is formed by the self weight of the second face material, the press from the moving support mechanism, or the like. The curable resin composition is pushed and expanded to fill the space with the resin layer (4) with the photocurable resin 41 201210812 composition, and then when exposed to a high pressure environment in step (d), bubbles are formed less or The resin layer having no bubbles forms a layer of the photocurable resin composition. The pressure reduction environment at the time of superposition is 100 Pa or less, preferably 101 V or more. If the decompression environment is too low pressure, there will be a resin layer. It is possible to form an adverse effect on each component (such as a curable compound, a photopolymerization initiator, a polymerization terminator, a light stabilizer, etc.) contained in the photocurable resin composition. For example, if the decompression environment belongs to If the pressure is too low, the components may be vaporized, and it takes time to provide a reduced pressure environment. The pressure in the reduced pressure environment is preferably 15 to 40 Pa. From the first surface material to the second surface material. The time until the time when the pressure-reducing environment is released is not particularly limited, and after the resin layer-forming photocurable resin composition is sealed, the pressure-reducing environment can be immediately released, and the resin layer can be cured by light. After the resin composition is sealed, the reduced pressure state is maintained for a predetermined period of time, and the photocurable resin composition for resin layer formation flows in the sealed space by the reduced pressure for a predetermined period of time, and the second surface material and the second surface material are The interval between the face materials is uniform, and the temperature can be easily maintained and sealed even if the environmental pressure is increased. The time for maintaining the reduced pressure state can be a production time with a long time of several hours or more, preferably within one hour or less. In the manufacturing method of the present embodiment, when the photocurable resin composition for forming a sealing portion having a high degree of application is applied to form an uncured sealing portion, the step (c) can be used. The resin layer of the laminated precursor is formed into a thicker impurity having a thickness of 1 mm as a photocurable sapphire composition. 42 201210812 [Step (d)] In step (c), the decompression environment is released. After that, the laminated precursor is placed in a pressure environment with an ambient pressure of 50 kPa or more. If the laminated precursor is placed in a pressure environment of 50 kPa or more, the first surface material and the second surface material are conveniently raised toward each other. When the airtight resin composition for resin layer formation flows in the air bubbles, the entire sealed space is formed by the resin layer, so that there is a bubble in the sealed space in the laminated precursor. The photocurable resin composition is uniformly filled. The pressure environment is usually 80 kPa to 120 kPa, and the pressure environment may be atmospheric pressure or higher. The hardening of the photocurable resin composition yarn for resin layer formation can be carried out in the case where the apparatus is not required, and it is preferably an atmospheric pressure environment. There is no particular limitation on the temple door (hereinafter referred to as "Southern pressure holding time") when the resin layer-shaped fine-graded resin composition starts to harden from the time when the laminated precursor is placed in a pressure of 50 kPa or more. . When the layered month J body is taken out from the decompression device and moved to the hardening device until the t-step is started in the atmospheric pressure environment, the process is required to become the sewing time. Therefore, when placed under the atmosphere of the atmosphere, there is no bubble in the confined space of the laminated precursor' or during the process; in the case of Xiao (4), the photohardenability of the formation of the marshallic layer The resin composition is hardened. When the gas is accumulated for a period of time, the layer is maintained in the dynamic environment above (four) until the bubble disappears. Moreover, even if the pressure holding time is prolonged, it usually does not constitute an obstacle. Therefore, the other necessity in the process of 201210812 can be extended, and the high-pressure holding time can be extended for a long period of time or more, but From the viewpoint of production efficiency, it is preferably within 6 hours, and more preferably within 1 hour, in terms of improving production efficiency, particularly preferably within 10 minutes. Then, the layered precursor is placed in a pressure environment of 5 kPa or more, and the resin layer forming photocurable resin composition is cured to form a resin layer for bonding the display element and the protective sheet. In the display device, the photocurable resin composition for forming a resin layer and the photocurable resin composition for forming a sealing portion are irradiated with light to be cured. For example, a light source (such as an ultraviolet lamp, a high pressure mercury lamp, a black lamp, a chemical lamp, a UV lamp, or the like) is irradiated with ultraviolet rays or short-wavelength visible light to harden the photocurable resin composition. In addition, the uncured seal portion formed of the photocurable resin composition by the sealing portion is formed at the same time, and can be cured simultaneously with curing of the photocurable resin composition for forming a resin layer, or can be formed in the resin layer. The hardening resin composition is pre-hardened before being hardened. In addition, when a part of the transparent surface material is formed with a light-shielding printing portion and is held by the light-shielding printing portion to form a sealing portion, the use of the transparent surface material is performed when the resin layer forming photocurable resin composition is cured. It is difficult to harden the sealing portion by the light in the light transmitting portion, and the sealing portion can be cured only after the resin layer forming photocurable resin composition is cured. For example, from the side of the first surface material and the second surface material of the laminated precursor having light permeability, the light-curable resin composition for forming a resin layer is irradiated with light, and from the side of the laminated precursor, The uncured seal portion of the 201210812 and the graded resin composition for forming a resin layer are sandwiched between the light-shielding portion and the display element, and light irradiation is performed. In the first surface material and the second surface material, since the display element does not have light transmittance without being activated, light is irradiated from the side of the transparent surface material serving as the protective plate through the light transmitting portion. Further, when the light-shielding printing portion is provided in the peripheral portion of the transparent surface material, the portion which is held by the light-shielding printing portion and the display element has an unhardened seal. The photocurable resin composition for p or the formation of the correcting layer is not sufficiently cured by the light from the light transmitting portion of the transparent surface material. Therefore, light irradiation is performed from the side of the display element. The light is preferably ultraviolet light or visible light of 45 Å or less. In particular, when the transparent surface material is provided with an anti-reflection layer, and the anti-reflection layer or the moon-reflecting layer which has formed the anti-reflection layer, or an ultraviolet layer such as an adhesive layer between the anti-reflection film and the transparent surface material In the case of impenetrable, it is necessary to use visible light for hardening. A light source used for light irradiation from the side may be a light source used when light is irradiated from the side of the transparent surface material, but it is preferable from the viewpoint of the arrangement space of the light source and the efficient light irradiation applied to a specific place. It is an ultraviolet ray or a lED which emits visible light of 450 nm or less. The step of irradiating light may be performed by irradiating light from the side of the transparent surface material, and then irradiating light from the side, or vice versa, or simultaneously performing light irradiation, so as to further promote the uncured seal portion and the resin layer of the light-shielding printing portion. In the photocuring of the photocurable resin composition, it is preferred to perform light irradiation from the side or light irradiation from the side of the transparent surface material simultaneously with the side. In addition, when the photocurable resin composition for forming a resin layer is cured, or the curing time of the photocurable resin composition is required, the resin layer may be formed in the resin layer. After the hardening of the photocurable resin composition is substantially completed, the sealing portion is cured by irradiation with light from the side. [Specific Example] In the production method of the present embodiment, the ith surface material can be arbitrarily used as a back material or a surface material. Therefore, the display device can be manufactured in accordance with the following two methods in accordance with the selection of the second surface material. (α-l) The first surface material is a display element (back surface material), and the second surface material is a method of using a transparent surface material (surface material) as a protective sheet. U-2) The first surface material is a transparent surface material (surface material) used as a protective sheet. The second surface material is a method using a display element (back surface material). In the following, the case of the method U-1 is taken as an example, and the manufacturing method of the display device of the figure is specifically described using the drawings. (Step (a)) As shown in Figs. 3 and 4, the photocuring property of the sealing portion is formed by a dispenser (not shown) or the like along the peripheral edge portion of the display element 5 (the i-surface material). The resin composition forms an uncured seal portion 12. An arrangement such as an electric letter FPC for transmitting the display element is provided on the outer peripheral portion of the display element. In the manufacturing method of the fourth embodiment, when the respective faces (4) are held, it is preferable to use the display element as the first face material and to arrange it on the lower side. (Step (b)) Next, as shown in Fig. 5 and Fig. 6, the resin layer forming photocurable resin composition is supplied to the rectangular region 13 surrounded by the unsealed 46 201210812 sealing portion 12 of the display element. 14. The supply of the resin layer-forming photocurable resin composition 14 is a space in which the unhardened sealing portion 12 and the display element and the transparent surface material 10 (see Fig. 7) are sealed, and the resin layer can be used. The amount filled with the photocurable resin composition 14 is formed. The supply layer of the resin layer-forming photocurable resin composition 14 is as shown in Fig. 5 and Fig. 6 'The display element 50 is placed flat on the lower fixed plate 18, and is linearly formed by the dispenser 20 moving in the horizontal direction. The strip-shaped or dot-shaped supply resin layer forming photocurable resin composition 14 is used. The dispenser 20 is horizontally movable over the entire range of the region 13 by a known horizontal movement mechanism including a pair of guide screws 22 and a guide screw 24 orthogonal to the guide screw 22. Alternatively, instead of the dispenser 2, a mold coater can be used instead. (Step (c)) Next, as shown in Fig. 7, the display element 5A and the transparent surface material 1 (the second surface material) are carried into the decompression device 26. In the upper portion of the decompression device 26, a top plate 3A having a plurality of adsorption pads 32 is disposed, and a lower plate 31 is disposed at a lower portion. The upper plate 30 is movable in the vertical direction by the air cylinder 34. The transparent face material 10 is mounted on the adsorption pad 32. The display element 50 is fixed to the lower fixed plate 31 with the surface of the resin layer-forming photocurable resin composition 14 facing upward. Next, the air in the decompression device 26 is sucked by the vacuum pump 28. After the ambient pressure in the decompression device 26 reaches the decompression environment of, for example, i5 to 4 〇pa, the transparent surface material 1 进行 is held by the adsorption 32 of the upper plate and held in the state of the adsorption of 2012 20121212, and is directed downward. The standby display element 50' causes the cylinder 34 to start and descend. Then, the display element 50 and the transparent surface material 10 are overlapped with each other via the unhardened sealing portion 12 to form a laminated precursor ', and the laminated precursor is held for a predetermined period of time under a reduced pressure environment. In addition, the mounting position of the display element 50 to the lower fixed plate 31, the number of the adsorption pads 32, and the mounting position of the transparent surface material 10 to the upper fixed plate 30, etc., match the size and shape of the display element 50 and the transparent surface material 1〇. Wait and adjust accordingly. In this case, the electrostatic chuck is used in the adsorption pad, and the glass substrate can be stably maintained in a reduced pressure environment by the electrostatic chuck holding method described in the specification attached to Japanese Patent Application No. 2008-206124 (incorporating this specification). (Step (d)) Next, after the inside of the decompression device 26 is formed, for example, at atmospheric pressure, the laminated precursor is taken out from the decompression device 26. When the laminated precursor is placed in an atmospheric pressure environment, the surface on the display element 50 side of the laminated precursor and the surface on the side of the transparent surface material 1 are conveniently pressed by atmospheric pressure, and the resin layer in the sealed space is formed with light. The curable resin composition 14 is pressurized by the display element 50 and the transparent face material 10. By this pressure, the resin layer forming photocurable resin composition I4 flows in the sealed space, and the entire sealed space is uniformly filled with the resin layer forming photocurable resin composition M. The chest is then placed on the transparent surface material & the light-shielding printing portion 'when the uncured seal portion held by the light-shielding stamp and the tree-shaped layer are formed with the photocurable resin side: when it is hardened first, as shown in Fig. 8 The photocurable resin conjugate 14' of the uncured seal layer formed by the side light-printing portion 55 of the laminated precursor and the display element 5g covers the display element 48 201210812 Irradiation with visible light of 450 nm or less and irradiation of light (ultraviolet rays or visible light of 450 nm or less) to the resin layer forming photocurable resin composition 14 from the side of the transparent surface material 10 through the light transmitting portion 56 The unhardened sealing portion 12 and the resin layer in the laminated precursor are cured by the photocurable resin composition 14, and the display device i is obtained. When the light-shielding printing portion is not provided on the transparent surface material, the laminated precursor is entirely irradiated with light from the side of the transparent surface material 10, and the uncured sealing portion 12 and the resin layer are formed in the laminated precursor. The photocurable resin composition 14 is cured to obtain a display device 1. In the case of the above-described method (a _ 1), the method of manufacturing the display device of the present embodiment will be specifically described. In the case of the other method (α _2), the display device can be manufactured in the same manner. [Operation and Effect: Manufacturing Method of Display Device] According to the method of manufacturing the display device of the present embodiment described above, it is possible to manufacture a large-area display device without generating bubbles in the resin layer. It is assumed that air bubbles remain in the photocurable resin composition for forming a resin layer which is sealed under reduced pressure, and the pressure is applied to the photocurable resin composition for forming a resin layer which is sealed under a high pressure environment before curing. The volume of the bubble can be reduced, and the bubble can be easily eliminated. For example, in the photocurable resin composition for forming a resin layer which has been sealed at 100 Pa, the volume of gas in the bubble can be considered to be 1/1000 at 100 kPa. Since the gas is dissolved in the photocurable resin composition for forming a resin layer, the gas in the fine volume bubbles is quickly dissolved in the resin layer forming photocurable resin composition and disappears. In addition, even if a pressure such as an atmospheric pressure is applied to the resin layer forming photocurable resin composition after sealing, the liquid resin composition for forming a liquid resin layer is a fluid composition, and thus the pressure system is used. Evenly distributed on the surface of the display element does not exert a stress on a part of the surface of the display element which is in contact with the resin layer forming photocurable resin composition, and the damage to the display element is low. Further, the interfacial adhesion between the resin layer formed by curing the resin layer-forming photocurable resin composition and the display element and the transparent surface material is in contact with the interface adhesion force by thermal fusion. In addition, the photocurable resin layer-forming photocurable resin composition is pressed and adhered to the surface of the display element or the transparent surface material, and is cured in this state, so that a higher interfacial adhesion force can be obtained and It is rare to obtain a uniform surface of the display element and the transparent face material, followed by a decrease in the locality of the interface. Therefore, there is a low possibility that peeling occurs on the surface of the resin layer, and there is a low possibility that water or corrosive gas is infiltrated from a portion where the boundary adhesion is insufficient. In addition, a method of injecting a photocurable resin composition into a fluid resin layer in a narrow and wide area between two sheets of materials (injection method) produces less bubbles and can be filled in a short time. A photocurable resin composition for forming a resin layer. Further, the photocurable resin composition for forming a resin layer has a small viscosity limitation, and the photocurable resin composition for forming a resin layer having a high viscosity can be easily filled. Therefore, a photocurable resin composition for forming a high-viscosity resin layer containing a high molecular weight curable compound capable of increasing the strength of the resin layer can be used. 50 201210812 Further, the photopolymerization initiator (C2) of the photocurable resin composition for resin layer formation uses a photopolymerization initiator (C1) having an absorption wavelength region (λ2) which is smaller than the uncured seal portion. The absorption wavelength region (λ1) is further on the long wavelength side of the photopolymerization initiator (C2), and the light irradiated from the side of the layered precursor is wavelength light in the absorption wavelength region (λ1). Both the wavelength light in the absorption wavelength region (λ2) can be used to make the absorption wavelength region which is not absorbed by the photopolymerization initiator (C1) of the uncured seal portion When the photocurable resin composition for forming a resin layer which is sandwiched by the display element in the light-shielding portion is reached, the photopolymerization initiator (C2) having the absorption wavelength region (λ2) is used to sufficiently perform the light for forming the resin layer. Hardening of the curable resin composition. [Operation: Hardening Resin Composition] The bonding between the display element and the transparent surface material can reduce the shrinkage factor at the time of curing the curable resin or reduce the elastic modulus of the resin layer after curing. The applied stress ' effectively prevents the occurrence of display spots and the like from damaging the display quality. However, if the molecular weight per hardened portion of the curable compound is increased to reduce the shrinkage at the time of curing, the viscosity of the curable compound becomes large, and the uniform supply of the surface of the surface of the curable resin composition tends to be difficult. There is a possibility that the hardening reaction at the time of hardening is uneven. In addition, when the non-hardening component which does not contribute to hardening is contained in order to reduce the elastic modulus of the resin layer after hardening, the compatibility of the curable resin composition may fall, and it may damage. The transparency of the cured resin composition or the adhesion between the resin layer and the surface of the surface after hardening is lowered, and there is a possibility that the surface material and the back material may be peeled off over time. On the other hand, the curable resin composition of the present invention contains, in particular, 10 to 90% by mass of a non-curable oligomer having 8 to 3 hydroxyl groups per molecule, which does not form a resin layer during curing. When the curable compound (II) in the photocurable resin composition is subjected to a non-hardening component which is subjected to a curing reaction, and the curable compound (II) is present, a hydroxyl group which does not react during curing is present, whereby The photocurable resin composition for forming a resin layer when not cured is excellent in stability, and the viscosity can be lowered, and the curing reaction uniformity at the time of curing is good, and shrinkage at the time of hardening can be reduced, and the hardening can be reduced. The modulus of elasticity of the resin. When the shrinkage at the time of hardening is lowered and the elastic modulus of the resin after hardening is lowered, the stress caused by the hardening shrinkage of the resin layer is lowered. When the photocurable resin composition for forming a resin layer is not cured, the stability of the curing reaction is good, and the resin layer having good transparency can be easily obtained. When the viscosity of the photocurable resin composition for forming a resin layer in the unhardened state is lowered, the foam can be sufficiently suppressed by (4), and a good interfacial bonding force between the face material and the resin layer can be easily obtained. In particular, when the display element is a liquid crystal display element, or even an IPS (In-plane Switching) liquid crystal display element, or an optical film attached to the display surface on the display surface (ΤΜ_价_〇) In the case of a liquid crystal display device, since the stress applied to the display element is likely to adversely affect the display quality, the bonding layer preferably has a low elastic modulus. Therefore, the display device using the curable resin composition of the present invention is used. 52 201210812 The display element is preferably a liquid crystal display element, more preferably an IPS type liquid crystal display element or a TN type liquid crystal display element. Further, the curable resin composition of the present invention is not limited to use. The same effect can be obtained by applying the same to the laminated body in which a pair of surface materials are laminated via a resin layer. Further, the curable resin composition of the present invention may be a thermosetting resin composition. In the case of the curable group of the curable compound, a known thermosetting group is used. Further, a known thermal polymerization initiator is contained as needed. In the above embodiment, 'when the resin When the curable resin composition for forming is thermosetting, it is preferable that the curable resin composition for forming a sealing portion is thermosetting. In particular, since the photocurable resin composition does not require high temperature during hardening. Therefore, the viewpoint of less adverse effects on the surface material due to high temperature is preferable. In the case of using a photopolymerization initiator and a thermal polymerization initiator, photohardening and thermal hardening can be simultaneously performed, or Further, the method of producing a laminate using the curable resin composition of the present invention is not limited to the method of the above embodiment, and a known method is suitably used.
