本發明係一種經由光硬化樹脂層將圖像顯示構件與彎曲之透光性罩蓋構件積層而成之圖像顯示裝置之製造方法，且其係具有以下之步驟(A)～(E)之製造方法。以下，一面參照圖式一面詳細說明各步驟。 ＜步驟(A)：塗佈步驟＞ 首先，如圖1A所示般準備彎曲之透光性罩蓋構件1，如圖1B所示般藉由分注器D等將光硬化性樹脂組合物2塗佈於透光性罩蓋構件1之凹部面1a。該光硬化性樹脂組合物2之塗佈量係根據圖像顯示元件之尺寸或形狀、用途等而不同，通常，於對45(w)×80(l)×3(t)mm(曲率半徑(r)：300 mm)之彎曲透光性罩蓋構件以接觸透光性罩蓋構件之未彎曲之兩邊之形式貼合40(w)×80(l)mm之圖像顯示構件之情形時，較佳為23.44 cc且彎曲最深部之厚度成為670 μm，更佳為23.76 cc且可於透光性罩蓋構件之未彎曲之兩邊與圖像顯示構件之間設置約100 μm之間隙。該間隙亦取決於圖像顯示裝置之設計，較佳為50 μm以上800 μm以下。又，此種塗佈量可藉由一次塗佈操作滿足，亦可藉由複數次塗佈操作滿足。 (透光性罩蓋構件1) 作為彎曲之透光性罩蓋構件1之具體形狀，可列舉：向一方向彎曲之形狀(例如將圓柱管以平行於其中心軸之平面切斷所獲得之劣弧側之形狀(以下稱為橫槽形狀))(圖1A)、或向X方向與Y方向彎曲之形狀(圖1C)、向360°方向彎曲之形狀(例如將球以不包含其中心點之平面切斷所獲得之劣弧側之形狀)(圖1D)等。亦可於該等形狀之中央部形成有平坦部1b(例如圖1E)。 於透光性罩蓋構件1為橫槽形狀之情形時(圖1A)，較佳為於其兩端部1x與1y之內側設置劃分光硬化性樹脂組合物之塗佈區域之內側擋材3(圖1F)，或於其兩端部1x與1y之外側設置劃分光硬化性樹脂組合物之塗佈區域之外側擋材4(圖1G)。作為內側擋材3及外側擋材4，可由不與所塗佈之光硬化性樹脂組合物相容而可將其阻擋，且於光硬化性樹脂組合物之暫時硬化後能簡便地去除之公知材料所形成。例如作為內側擋材3，可列舉：將具備微黏著層之公知之熱塑性彈性體帶等以堤壩狀貼附於透光性罩蓋構件1之端部內側者。作為外側擋材4，可列舉矽酮片材、氟樹脂片材等。 再者，於透光性罩蓋構件1為圖1C或圖1D之態樣之情形時，亦可去掉擋材。又，於為圖1A、1B之態樣之情形時，亦可對與內側擋材3對應之透光性罩蓋構件1之表面實施用以防止光硬化性樹脂組合物之流動之表面處理(例如根據光硬化性樹脂組合物之特性而進行粗面化處理、親水化處理、或撥水化處理等)。 作為透光性罩蓋構件1之材料，只要具有可看到形成於圖像顯示構件之圖像般之透光性即可，可列舉：玻璃、丙烯酸系樹脂、聚對苯二甲酸乙二酯、聚萘二甲酸乙二酯、聚碳酸酯等樹脂材料。對於該等材料，可實施單面或兩面硬塗處理、抗反射處理等。透光性罩蓋構件1之彎曲之形狀或厚度等尺寸特性、彈性等部位利敵物性可根據使用目的而適當決定。 (光硬化性樹脂組合物2) 塗佈於透光性罩蓋構件1之凹部面1a之光硬化性樹脂組合物2之性狀較佳為液狀。若使用液狀者，則可於透光性罩蓋構件1之凹部面1a以組合物表面變得平坦之方式填充光硬化性樹脂組合物2。此處所謂液狀，係藉由錐板型黏度計而顯示0.01～100 Pa·s(25℃)之黏度者。 此種光硬化性樹脂組合物2可較佳地例示含有基質成分(成分(a))、丙烯酸系單體成分(成分(b))、及光聚合起始劑(成分(c))者。視需要，可進而含有塑化劑成分(成分(d))。再者，光硬化性樹脂組合物2之最終硬化收縮率為3%以上。亦可為5%以上。 此處所謂“最終硬化收縮率”，意指使光硬化性樹脂組合物2自未硬化狀態至完全硬化狀態之間所產生之硬化收縮率。此處所謂完全硬化，意指如下述般以硬化率至少成為90%之方式硬化之狀態。以下，將最終硬化收縮率稱為總硬化收縮率。又，將使硬化性樹脂組合物自未硬化狀態至暫時硬化狀態之間所產生之硬化收縮率稱為暫時硬化收縮率。進而，於正式硬化步驟中，自暫時硬化狀態至完全硬化狀態之間所產生之硬化收縮率稱為正式硬化收縮率。 關於光硬化性樹脂組合物之總硬化收縮率，可使用電子比重計(Alfa Mirage股份有限公司製造之SD-120L)測定未硬化(換言之，硬化前)之組合物與完全硬化後之固體之完全硬化物之比重，並根據兩者之比重差藉由下式而算出。又，關於光硬化性樹脂組合物之暫時硬化樹脂之暫時硬化收縮率，可使用電子比重計(Alfa Mirage股份有限公司製造之SD-120L)測定未硬化(換言之，硬化前)之組合物與暫時硬化後之固體之暫時硬化物之比重，並根據兩者之比重差藉由下式而算出。正式硬化收縮率可藉由將總硬化收縮率減去暫時硬化收縮率而算出。 總硬化收縮率(%)=[(完全硬化物比重－未硬化組合物比重)/完全硬化物比重]×100 暫時硬化收縮率(%)=[(暫時硬化物比重－未硬化組合物比重)/暫時硬化物比重]×100 正式硬化收縮率(%)=全硬化收縮率－暫時硬化收縮率 成分(a)之基質成分為透光性硬化樹脂層之膜形成成分，為含有彈性體及丙烯酸系低聚物中之至少任一者之成分。亦可將兩者併用作成分(a)。 作為彈性體，可較佳地列舉：較佳為包含丙烯酸酯之共聚物之丙烯酸系共聚物、聚丁烯、聚烯烴等。再者，該丙烯酸酯共聚物之重量平均分子量較佳為5000～500000，聚丁烯之重複數n較佳為10～10000。 另一方面，作為丙烯酸系低聚物，較佳為可列舉：骨架中具有聚異戊二烯、聚胺基甲酸酯、聚丁二烯等之(甲基)丙烯酸酯系低聚物。再者，於本說明書中，「(甲基)丙烯酸酯」之用語包含丙烯酸酯與甲基丙烯酸酯。 作為聚異戊二烯骨架之(甲基)丙烯酸酯系低聚物之較佳具體例，可列舉：聚異戊二烯聚合物之順丁烯二酸酐加成物與甲基丙烯酸2-羥基乙酯之酯化物(UC102(聚苯乙烯換算分子量17000)，可樂麗股份有限公司；UC203(聚苯乙烯換算分子量35000)，可樂麗股份有限公司；UC-1(分子量約25000)，可樂麗股份有限公司)等。 又，作為具有聚胺基甲酸酯骨架之(甲基)丙烯酸酯系低聚物之較佳具體例，可列舉：脂肪族丙烯酸胺基甲酸酯(EBECRYL230(分子量5000)，Daicel-Allnex股份有限公司；UA-1，Light chemical工業股份有限公司)等。 作為聚丁二烯骨架之(甲基)丙烯酸酯系低聚物，可採用公知者。 成分(b)之丙烯酸系單體成分於圖像顯示裝置之製造步驟中，為了對光硬化性樹脂組合物賦予充分之反應性及塗佈性等而被用作反應性稀釋劑。作為此種丙烯酸系單體，可列舉：甲基丙烯酸2-羥基丙酯、甲基丙烯酸4-羥基丁酯、丙烯酸硬脂酯、丙烯酸苄酯、丙烯酸四氫糠酯、丙烯酸二環戊烯酯、甲基丙烯酸二環戊烯氧基乙酯、丙烯酸異𦯉基酯、丙烯酸雙環戊酯、甲基丙烯酸月桂酯等。 作為成分(c)之光聚合起始劑，可使用公知之光自由基聚合起始劑，例如可列舉：1-羥基-環己基苯基酮(Irgacure184，BASF日本股份有限公司)、2-羥基-1-{4-[4-(2-羥基-2-甲基-丙醯基)苄基]苯基}-2-甲基-1-丙烷-1-酮(Irgacure127，BASF日本股份有限公司)、二苯甲酮、苯乙酮等。 相對於基質成分(a)中之丙烯酸系低聚物及丙烯酸系單體成分(b)之合計100質量份，此種光聚合起始劑若過少則紫外線照射時變得硬化不足，若過多則由裂解所導致之釋氣增加而有發泡不良之傾向，故較佳為0.1～5質量份，更佳為0.2～3質量份。 又，光硬化性樹脂組合物2可為了調整分子量而含有鏈轉移劑。例如可列舉：2-巰基乙醇、月桂基硫醇、縮水甘油基硫醇、巰基乙酸、硫代乙醇酸2-乙基己酯、2,3-二巰基-1-丙醇、α-甲基苯乙烯二聚物等。 又，光硬化性樹脂組合物2進而視需要可含有矽烷偶合劑等接著改善劑、抗氧化劑等一般添加劑。 對於光硬化性樹脂組合物2而言，由於下述暫時硬化步驟之後的正式硬化步驟中其硬化收縮率被抑制於未達3%，故基本上無需含有塑化劑成分，但為了對硬化樹脂層賦予緩衝性，並且使光硬化性樹脂組合物之硬化收縮率降低，可於不損及本發明之效果之範圍內含有塑化劑成分(成分(d))。因此，光硬化性樹脂組合物中，成分(a)之基質成分與成分(b)之丙烯酸系單體成分之合計含量較佳為25～85質量%，成分(d)之塑化劑成分之含量為0～65質量%之範圍。 成分(d)之塑化劑成分於紫外線之照射下不與成分(a)之基質成分及成分(b)之丙烯酸系單體成分發生反應。此種塑化劑成分含有固體之黏著賦予劑(1)與液狀油成分(2)。 作為固體之黏著賦予劑(1)，可列舉：萜烯樹脂、萜酚樹脂、氫化萜烯樹脂等萜烯系樹脂，天然松香、聚合松香、松香酯、氫化松香等松香樹脂，萜烯系氫化樹脂。又，亦可使用將上述丙烯酸系單體成分預先低分子聚合化而成之非反應性低聚物，具體而言，可列舉：丙烯酸丁酯與丙烯酸2-己酯及丙烯酸之共聚物、或丙烯酸環己酯與甲基丙烯酸之共聚物等。 作為液狀油成分(2)，可含有聚丁二烯系油、或聚異戊二烯系油等。 ＜步驟(B)：暫時硬化步驟＞ 其次，如圖2A所示，對所塗佈之光硬化性樹脂組合物2照射紫外線UV而使其暫時硬化，於透光性罩蓋構件1之凹部面1a(通常於其中央部)形成具有基於光硬化性樹脂組合物2之硬化收縮之微小凹陷5a(例如圖2B中為X字狀之凹陷，亦可為線狀等其他形狀之凹陷)的暫時硬化樹脂層5。所謂微小凹陷5a中之“微小”，意指由暫時硬化收縮所導致之體積變動量。此處，暫時硬化之原因在於：使光硬化性樹脂組合物2成為不流動之狀態而提高操作性。此種暫時硬化之水準係暫時硬化樹脂層5之硬化率(凝膠分率)成為較佳為10～90%、更佳為40～90%般的水準。又，所謂硬化率(凝膠分率)，係定義為紫外線照射後之(甲基)丙烯醯基之存在量相對於紫外線照射前之光硬化性樹脂組合物2中之(甲基)丙烯醯基之存在量的比率(消費量比率)之數值，該數值越大表示越進行硬化。 再者，硬化率(凝膠分率)可藉由以下方式算出：將紫外線照射前之樹脂組合物層之FT-IR測定圖中的距基線之1640～1620 cm-1
之吸收峰高度(X)、與紫外線照射後之樹脂組合物層之FT-IR測定圖中的距基線之1640～1620 cm-1
之吸收峰高度(Y)代入至以下之數式中。 硬化率(%)={(X－Y)/X}×100 關於紫外線之照射，只要能以硬化率(凝膠分率)較佳為成為10～80%之方式暫時硬化，則光源之種類、輸出、累計光量等並無特別限制，可採用公知之利用紫外線照射的(甲基)丙烯酸酯之光自由基聚合處理條件。 又，關於紫外線照射條件，較佳為於上述硬化率之範圍內，選擇於下述步驟(C)之貼合操作時不產生暫時硬化樹脂層5之滴液或變形般之條件。若以黏度來表現不產生此種滴液或變形般之條件，則成為20 Pa·S以上(錐板流變儀，25℃，錐及板C35/2，轉速10 rpm)。 關於暫時硬化中之硬化之水準，以於下述正式硬化步驟中自暫時硬化樹脂層5至硬化樹脂層之間所產生之硬化收縮率成為未達3%之方式進行硬化。即，於總硬化收縮率為5%之光硬化性樹脂組合物2之情形時，於暫時硬化時至少以2%暫時硬化收縮。 再者，於步驟(A)中設有內側擋材3或外側擋材4之情形時，較佳為於步驟(B)之後、步驟(C)之前去除內側擋材3或外側擋材4。其原因在於：光硬化性樹脂組合物2已暫時硬化，不會產生樹脂流動。 ＜步驟(C)：光硬化性樹脂組合物之再填充＞ 其次，將與暫時硬化樹脂層5之微小凹陷5a對應之量的光硬化性樹脂組合物2塗佈於暫時硬化樹脂層5(圖3A)或通常平坦之圖像顯示構件6(圖3B)。此處，與微小凹陷5a對應之量可藉由使用微小表面形狀測量裝置(例如3D測定雷射顯微鏡(OLS4000系列)，島津製作所股份有限公司)測量微小凹部5a之凹部形狀而算出。或亦可根據光硬化性樹脂組合物之暫時硬化收縮率及使用量(體積)而決定。 又，該步驟所使用之光硬化性樹脂組合物2自折射率之觀點而言，較佳為使用與步驟(A)中所使用之光硬化性樹脂組合物2相同者，但若折射率大致相同，亦可使用不同組成之光硬化性樹脂組合物。又，光硬化性樹脂組合物之塗佈較佳為藉由先前公知之方法以於微小凹陷5a中填充光硬化性樹脂組合物2之方式進行。例如於將光硬化性樹脂組合物2塗佈於暫時硬化樹脂層5或圖像顯示構件6之情形時，只要以填埋微小凹部5a之方式塗佈成線狀(圖3A、3B)、X字狀，或於中央部塗佈成點狀即可。 再者，即便於光硬化性樹脂組合物2之塗佈位置自微小凹部5a偏移之情形時，亦由於不使塗佈之光硬化性樹脂組合物2暫時硬化而以保持流動性之狀態進行真空貼合，故可使光硬化性樹脂組合物2向微小凹部5a適當地移動。 作為圖像顯示構件6，可列舉：液晶顯示面板、有機EL顯示面板、電漿顯示面板、觸控面板等。此處所謂觸控面板，意指將如液晶顯示面板般之顯示元件與如觸控板般之位置輸入裝置組合而成的圖像顯示、輸入面板。 再者，作為上文中說明之步驟(B)及該步驟(C)之較佳態樣，可列舉：於步驟(B)中，於透光性罩蓋構件之凹部面之至少中央部產生微小凹陷，並且於步驟(C)中，將相當於微小凹陷體積之70%以上的光硬化性樹脂組合物塗佈於對應之暫時硬化樹脂層或圖像顯示構件之態樣。 ＜步驟(D)：積層步驟＞ 繼而，經由暫時硬化樹脂層5將圖像顯示構件6與透光性罩蓋構件1積層(圖4)。積層可藉由使用公知之壓接裝置於10℃～80℃進行加壓而進行，為了不使氣泡進入暫時硬化樹脂層5與圖像顯示構件6或透光性罩蓋構件1之間，較佳為藉由所謂真空貼合法進行積層。 再者，較佳為於步驟(D)之後、步驟(E)之前，對積層物進行公知之加壓消泡處理(處理條件例：0.2～0.8 MPa，25～60℃，5～20 min)。 ＜步驟(E)：正式硬化步驟＞ 繼而，對夾持於圖像顯示構件6與透光性罩蓋構件1之間的暫時硬化樹脂層5照射紫外線UV而使其正式硬化，藉此形成透光性硬化樹脂層7(圖5)。藉此，獲得目標圖像顯示裝置。再者，該步驟中進行正式硬化之原因在於：使暫時硬化樹脂層5充分硬化，將圖像顯示構件6與透光性罩蓋構件1接著並積層。此種正式硬化之水準為透光性硬化樹脂層7之硬化率(凝膠分率)成為較佳為90%以上、更佳為95%以上般的水準。 再者，關於透光性硬化樹脂層7之透光性之水準，只要為可看到形成於圖像顯示構件6之圖像般之透光性即可。 [實施例] 以下，藉由實施例具體說明本發明。再者，於以下之實施例中，光硬化性樹脂組合物之總硬化收縮率、暫時硬化收縮率、正式硬化收縮率係使用電子比重計(Alfa Mirage股份有限公司製造之SD-120L)測定光硬化性樹脂組合物之比重、暫時硬化物及完全硬化物各自之比重，將該等測定結果代入至下式中而算出。 總硬化收縮率(%)=[(完全硬化物比重－未硬化組合物比重)/完全硬化物比重]×100 暫時硬化收縮率(%)=[(暫時硬化物比重－未硬化組合物比重)/暫時硬化物比重]×100 正式硬化收縮率(%)=全硬化收縮率－暫時硬化收縮率 比較例1 (步驟(A)：塗佈步驟) 首先，準備45(w)×80(l)×3(t)mm尺寸之透明樹脂板(聚對苯二甲酸乙二酯板)，於寬度方向上以曲率半徑(r)成為300 mm之方式藉由公知之方法使其彎曲，獲得樹脂罩蓋(圖1A)作為彎曲之橫槽形狀之透光性罩蓋構件。 另外，將具有聚丁二烯骨架之(甲基)丙烯酸系低聚物(TE-2000，日本曹達股份有限公司)50質量份、甲基丙烯酸羥基乙酯20質量份、光聚合起始劑10質量份(BASF日本股份有限公司製造之Irgacure184 3質量份、DKSH日本股份有限公司製造之SpeedCure TPO 7質量份)均勻混合，製備光硬化性樹脂組合物。該光硬化性樹脂組合物於硬化率0%至90%之間顯示5.6%之總硬化收縮率。 其次，以2片矽酮橡膠片材作為外側擋材而夾住橫槽形狀之樹脂罩蓋之兩端(圖1G)。於該樹脂罩蓋之凹部，使用樹脂用分注器以中央部之厚度成為880 μm厚之方式噴出所製備之光硬化性樹脂組合物，形成光硬化性樹脂組合物膜。 (步驟(B)：暫時硬化步驟) 其次，對該光硬化性樹脂組合物膜使用紫外線照射裝置(LC-8，Hamamatsu Photonics股份有限公司)，以累計光量成為1200 mJ/cm2
之方式照射6秒200 mW/cm2
強度之紫外線，藉此使光硬化性樹脂組合物膜暫時硬化而形成暫時硬化樹脂層，進而去除外側擋材。暫時硬化時，可觀察到於暫時硬化樹脂層之中央部形成有微小凹部(圖2B)。再者，暫時硬化收縮率為3.8%。 再者，暫時硬化樹脂層之硬化率係以FT-IR測定圖中的距基線之1640～1620 cm-1
之吸收峰高度作為指標而求出，結果約70%。 (步驟(D)：積層步驟) 其次，於40(W)×80(L)mm尺寸之平坦之液晶顯示元件的積層有偏光板之面上，將步驟(B)中所獲得之透光性罩蓋構件以其暫時硬化樹脂層側成為偏光板側之方式載置，自樹脂罩蓋側藉由真空貼合機(真空度50 Pa，貼合壓力0.07 MPa，貼合時間3秒，常溫)貼附(圖4)。 (步驟(E)：正式硬化步驟) 其次，對該液晶顯示元件自樹脂罩蓋側使用紫外線照射裝置(ECS-03601EG，Eye Graphics股份有限公司)以3000 mJ/cm2
照射紫外線(200 mW/cm2

Hereinafter, each step will be described in detail with reference to the drawings. <Step (A): Coating Step> First, as shown in FIG. 1A , a translucent cover member 1 that is bent is prepared, and as shown in FIG. 1B , the photocurable resin composition 2 is dispensed with a dispenser D or the like. It is apply|coated to the recessed part surface 1a of the translucent cover member 1. The coating amount of the photocurable resin composition 2 varies depending on the size, shape, application, etc. of the image display element, but generally, it is about 45(w)×80(l)×3(t) mm (radius of curvature). (r): When the curved translucent cover member of 300 mm) is attached to the image display member of 40(w)×80(l) mm in the form of contacting the unbent two sides of the translucent cover member , preferably 23.44 cc and the thickness of the deepest bent portion is 670 μm, more preferably 23.76 cc, and a gap of about 100 μm can be set between the unbent two sides of the translucent cover member and the image display member. The gap also depends on the design of the image display device, and is preferably 50 μm or more and 800 μm or less. In addition, such a coating amount may be satisfied by one coating operation, or may be satisfied by a plurality of coating operations. (Light-transmitting cover member 1) As a specific shape of the curved light-transmitting cover member 1, a shape that is curved in one direction (for example, a cylindrical tube obtained by cutting a plane parallel to its central axis) can be mentioned. The shape of the inferior arc side (hereinafter referred to as the transverse groove shape)) (Fig. 1A), or the shape curved in the X direction and the Y direction (Fig. 1C), the shape curved in the 360° direction (for example, the ball is not included in its center. The shape of the inferior arc side obtained by cutting the plane of the point) (Fig. 1D) and so on. The flat part 1b (for example, FIG. 1E) may be formed in the center part of these shapes. In the case where the translucent cover member 1 is in the shape of a horizontal groove ( FIG. 1A ), it is preferable to provide an inner baffle 3 for dividing the coating area of the photocurable resin composition on the inner side of both ends 1x and 1y thereof. (FIG. 1F), or the outer side baffles 4 (FIG. 1G) for dividing the coating area of the photocurable resin composition are provided on the outer sides of both ends 1x and 1y. It is known that the inner stopper 3 and the outer stopper 4 can be blocked by being incompatible with the photocurable resin composition to be applied, and can be easily removed after the temporary hardening of the photocurable resin composition material formed. For example, as the inner baffle 3, a well-known thermoplastic elastomer tape or the like provided with a micro-adhesive layer is affixed to the inner side of the end portion of the translucent cover member 1 in a bank shape. As the outer stopper 4, a silicone sheet, a fluororesin sheet, etc. are mentioned. Furthermore, when the translucent cover member 1 is in the state of FIG. 1C or FIG. 1D , the blocking material can also be removed. 1A and 1B, the surface of the translucent cover member 1 corresponding to the inner baffle 3 may also be subjected to surface treatment for preventing the flow of the photocurable resin composition ( For example, according to the characteristics of the photocurable resin composition, roughening treatment, hydrophilization treatment, water repellency treatment, etc. are performed). As the material of the light-transmitting cover member 1, what is necessary is to have light-transmitting properties such that the image formed on the image display member can be seen, and examples thereof include glass, acrylic resin, polyethylene terephthalate , Polyethylene naphthalate, polycarbonate and other resin materials. For these materials, one-side or two-side hard coating treatment, anti-reflection treatment, and the like can be performed. The shape of the light-transmitting cover member 1, dimensional characteristics such as thickness, and physical properties such as elasticity, etc., can be appropriately determined according to the purpose of use. (Photocurable resin composition 2) It is preferable that the property of the photocurable resin composition 2 apply|coated to the recessed part surface 1a of the translucent cover member 1 is a liquid state. If a liquid form is used, the photocurable resin composition 2 can be filled in the recessed part surface 1a of the translucent cover member 1 so that the composition surface may become flat. The term "liquid state" as used herein refers to what shows a viscosity of 0.01 to 100 Pa·s (25° C.) by a cone-plate viscometer. Such a photocurable resin composition 2 can preferably be exemplified by those containing a matrix component (component (a)), an acrylic monomer component (component (b)), and a photopolymerization initiator (component (c)). If necessary, a plasticizer component (component (d)) may be further contained. In addition, the final cure shrinkage of the photocurable resin composition 2 is 3% or more. It can also be more than 5%. Here, the "final cure shrinkage rate" means the cure shrinkage rate generated between the uncured state and the completely cured state of the photocurable resin composition 2 . The complete hardening here means a state of hardening so that the hardening rate becomes at least 90% as described below. Hereinafter, the final hardening shrinkage rate is referred to as the total hardening shrinkage rate. Moreover, the hardening shrinkage rate which makes a curable resin composition generate|occur|produce between an unhardened state and a temporary hardening state is called temporary hardening shrinkage rate. Furthermore, in the main hardening step, the hardening shrinkage rate generated between the temporary hardening state and the complete hardening state is called the main hardening shrinkage rate. The total curing shrinkage of the photocurable resin composition can be measured using an electronic hydrometer (SD-120L manufactured by Alfa Mirage Co., Ltd.) to measure the completeness of the uncured (in other words, before curing) composition and the fully cured solid. The specific gravity of the cured product was calculated by the following formula from the difference in specific gravity between the two. In addition, regarding the temporary hardening shrinkage rate of the temporary hardening resin of the photocurable resin composition, the unhardened (in other words, before hardening) composition and the temporary hardening can be measured using an electronic hydrometer (SD-120L manufactured by Alfa Mirage Co., Ltd.). The specific gravity of the temporarily hardened product of the solid after hardening was calculated by the following formula from the difference in specific gravity between the two. The actual hardening shrinkage rate can be calculated by subtracting the temporary hardening shrinkage rate from the total hardening shrinkage rate. Total hardening shrinkage rate (%)=[(Specific gravity of completely hardened material - Specific gravity of unhardened composition)/Specific gravity of completely hardened material]×100 Temporary hardening shrinkage rate (%)=[(Specific gravity of temporary hardened material - Specific gravity of unhardened composition) /Specific gravity of temporary hardened product]×100 Full hardening shrinkage rate (%)=total hardening shrinkage rate-temporary hardening shrinkage rate It is a component of at least one of the oligomers. Both can also be used in combination as component (a). As the elastomer, preferably, an acrylic copolymer, a polybutene, a polyolefin, etc., which are preferably a copolymer containing an acrylic ester, can be mentioned. Furthermore, the weight average molecular weight of the acrylate copolymer is preferably 5,000-500,000, and the repeating number n of the polybutene is preferably 10-10,000. On the other hand, as an acryl-type oligomer, the (meth)acrylate-type oligomer which has a polyisoprene, a polyurethane, a polybutadiene, etc. in a skeleton is mentioned preferably. In addition, in this specification, the term "(meth)acrylate" includes acrylate and methacrylate. Preferred specific examples of the (meth)acrylate-based oligomer of the polyisoprene skeleton include a maleic anhydride adduct of a polyisoprene polymer and a 2-hydroxy methacrylate. Ester of ethyl ester (UC102 (polystyrene conversion molecular weight 17000), Kuraray Co., Ltd.; UC203 (polystyrene conversion molecular weight 35000), Kuraray Co., Ltd.; UC-1 (molecular weight about 25000), Kuraray Co., Ltd. Ltd.) etc. Moreover, as a preferable specific example of the (meth)acrylate type oligomer which has a urethane skeleton, aliphatic acrylate urethane (EBECRYL230 (molecular weight 5000), Daicel-Allnex Co., Ltd. Co., Ltd.; UA-1, Light Chemical Industry Co., Ltd.), etc. As a (meth)acrylate type oligomer of a polybutadiene skeleton, a well-known thing can be employ|adopted. The acrylic monomer component of the component (b) is used as a reactive diluent in order to impart sufficient reactivity, coatability, etc. to the photocurable resin composition in the production process of the image display device. Examples of such acrylic monomers include 2-hydroxypropyl methacrylate, 4-hydroxybutyl methacrylate, stearyl acrylate, benzyl acrylate, tetrahydrofurfuryl acrylate, and dicyclopentenyl acrylate. , Dicyclopentenyloxyethyl methacrylate, Isosyl acrylate, Dicyclopentyl acrylate, Lauryl methacrylate, etc. As the photopolymerization initiator of the component (c), known photoradical polymerization initiators can be used, for example, 1-hydroxy-cyclohexyl phenyl ketone (Irgacure 184, BASF Japan Co., Ltd.), 2-hydroxy -1-{4-[4-(2-Hydroxy-2-methyl-propionyl)benzyl]phenyl}-2-methyl-1-propan-1-one (Irgacure127, BASF Japan Co., Ltd. ), benzophenone, acetophenone, etc. With respect to 100 parts by mass of the total of the acrylic oligomer and the acrylic monomer component (b) in the matrix component (a), if the amount of such a photopolymerization initiator is too small, the curing becomes insufficient when irradiated with ultraviolet rays, and if it is too large, the Since outgassing due to cracking increases and foaming tends to be poor, it is preferably 0.1 to 5 parts by mass, more preferably 0.2 to 3 parts by mass. Moreover, the photocurable resin composition 2 may contain a chain transfer agent in order to adjust molecular weight. For example, 2-mercaptoethanol, lauryl mercaptan, glycidyl mercaptan, thioglycolic acid, 2-ethylhexyl thioglycolate, 2,3-dimercapto-1-propanol, α-methyl Styrene dimer, etc. Moreover, the photocurable resin composition 2 may further contain general additives, such as adhesion improvers, such as a silane coupling agent, and antioxidant, as needed. In the photocurable resin composition 2, since the curing shrinkage is suppressed to less than 3% in the main curing step after the temporary curing step described below, there is basically no need to contain a plasticizer component, but in order to prevent the curing resin The layer provides cushioning properties, reduces the curing shrinkage of the photocurable resin composition, and can contain a plasticizer component (component (d)) within a range that does not impair the effects of the present invention. Therefore, in the photocurable resin composition, the total content of the matrix component of the component (a) and the acrylic monomer component of the component (b) is preferably 25 to 85% by mass, and the total content of the plasticizer component of the component (d) is preferably 25 to 85% by mass. The content is in the range of 0 to 65 mass %. The plasticizer component of component (d) does not react with the matrix component of component (a) and the acrylic monomer component of component (b) under the irradiation of ultraviolet rays. Such a plasticizer component contains a solid adhesion imparting agent (1) and a liquid oil component (2). Examples of the solid adhesion imparting agent (1) include terpene-based resins such as terpene resins, terpene phenol resins, and hydrogenated terpene resins; rosin resins such as natural rosin, polymerized rosin, rosin ester, and hydrogenated rosin; resin. In addition, non-reactive oligomers obtained by low-molecular-weight polymerization of the above-mentioned acrylic monomer components can also be used, and specific examples thereof include a copolymer of butyl acrylate, 2-hexyl acrylate, and acrylic acid, Copolymers of cyclohexyl acrylate and methacrylic acid, etc. As the liquid oil component (2), a polybutadiene-based oil, a polyisoprene-based oil, or the like may be contained. <Step (B): Temporary Hardening Step> Next, as shown in FIG. 2A , the applied photocurable resin composition 2 is irradiated with ultraviolet rays UV to be temporarily cured, and the concave surface of the translucent cover member 1 is formed. 1a (usually in the center portion) is formed with microscopic depressions 5a (eg, X-shaped depressions in FIG. 2B, but also linear depressions and other shaped depressions) based on the curing shrinkage of the photocurable resin composition 2. Hardened resin layer 5 . The "microscopic" in the microscopic recesses 5a means the amount of volume change due to temporary hardening shrinkage. Here, the reason for the temporary curing is to improve the workability by making the photocurable resin composition 2 in a non-fluid state. The level of such a temporary hardening is a level like the hardening rate (gel fraction) of the temporary hardening resin layer 5, Preferably it is 10-90%, More preferably, it is 40-90%. In addition, the hardening rate (gel fraction) is defined as the amount of (meth)acryloyl group present after ultraviolet irradiation with respect to the (meth)acryloyl group in the photocurable resin composition 2 before ultraviolet irradiation The numerical value of the ratio (consumption ratio) of the existing amount of the base, and the larger the numerical value, the more the hardening progresses. Further, the hardening rate (gel fraction) can be calculated by the following ways: from the baseline of 1640 - 1620 cm absorption peak height of the resin composition layer before the UV irradiation in FIG FT-IR measurement of -1 (X ), and the absorption peak height (Y) of 1640-1620 cm -1 from the base line in the FT-IR measurement chart of the resin composition layer after ultraviolet irradiation was substituted into the following equation. Hardening rate (%)={(X-Y)/X}×100 For ultraviolet irradiation, as long as the hardening rate (gel fraction) can be temporarily hardened so that the hardening rate (gel fraction) is preferably 10 to 80%, the type of light source , output, cumulative light intensity, etc. are not particularly limited, and known conditions for photoradical polymerization of (meth)acrylates by ultraviolet irradiation can be employed. Moreover, regarding the ultraviolet irradiation conditions, it is preferable to select conditions which do not produce dripping or deformation of the temporarily hardened resin layer 5 during the bonding operation of the following step (C) within the range of the above-mentioned curing rate. If the viscosity does not produce such dripping or deformation-like conditions, it becomes 20 Pa·S or more (cone and plate rheometer, 25°C, cone and plate C35/2, rotation speed 10 rpm). About the level of hardening in the temporary hardening, hardening was performed so that the hardening shrinkage rate generated between the temporary hardening resin layer 5 and the hardening resin layer in the following main hardening process might become less than 3%. That is, in the case of the photocurable resin composition 2 having a total curing shrinkage rate of 5%, the temporary curing shrinkage is at least 2% at the time of temporary curing. Furthermore, when the inner baffle 3 or the outer baffle 4 is provided in the step (A), it is preferable to remove the inner baffle 3 or the outer baffle 4 after the step (B) and before the step (C). The reason for this is that the photocurable resin composition 2 is temporarily cured, and resin flow does not occur. <Step (C): Refilling of the Photo-curable Resin Composition> Next, the photo-curable resin composition 2 in an amount corresponding to the minute depressions 5a of the temporarily-cured resin layer 5 is applied to the temporarily-cured resin layer 5 (Fig. 3A) or a generally flat image display member 6 (FIG. 3B). Here, the amount corresponding to the minute recesses 5a can be calculated by measuring the recess shape of the minute recesses 5a using a minute surface shape measuring apparatus (eg, a 3D measurement laser microscope (OLS4000 series), Shimadzu Corporation). Alternatively, it can also be determined according to the temporary curing shrinkage rate and the usage amount (volume) of the photocurable resin composition. In addition, the photocurable resin composition 2 used in this step is preferably the same as the photocurable resin composition 2 used in the step (A) from the viewpoint of the refractive index, but if the refractive index is approximately Similarly, photocurable resin compositions of different compositions can also be used. Moreover, it is preferable to carry out coating of the photocurable resin composition so that the photocurable resin composition 2 may be filled in the microdent 5a by the conventionally well-known method. For example, in the case of applying the photocurable resin composition 2 to the temporarily cured resin layer 5 or the image display member 6, it is only necessary to apply the photocurable resin composition 2 in a linear shape so as to fill the minute recesses 5a (FIGS. 3A and 3B), X It can be in the shape of a word, or it can be applied in the form of dots in the center. Furthermore, even in the case where the coating position of the photocurable resin composition 2 is shifted from the minute recesses 5a, the coating is performed in a state of maintaining fluidity because the coated photocurable resin composition 2 is not temporarily cured. Since the vacuum bonding is performed, the photocurable resin composition 2 can be appropriately moved to the minute recesses 5a. As the image display member 6, a liquid crystal display panel, an organic EL display panel, a plasma display panel, a touch panel, etc. are mentioned. The touch panel here refers to an image display and input panel that combines a display element such as a liquid crystal display panel and a position input device such as a touch panel. In addition, as a preferable aspect of the step (B) and the step (C) described above, in the step (B), at least the central portion of the recessed surface of the translucent cover member is formed with tiny particles. depression, and in step (C), the photocurable resin composition equivalent to more than 70% of the volume of the tiny depressions is coated on the corresponding temporary curing resin layer or the state of the image display member. <Step (D): Lamination Step> Next, the image display member 6 and the translucent cover member 1 are laminated via the temporarily cured resin layer 5 ( FIG. 4 ). The lamination can be performed by applying pressure at 10° C. to 80° C. using a known crimping device. In order to prevent air bubbles from entering between the temporarily hardened resin layer 5 and the image display member 6 or the light-transmitting cover member 1 , it is relatively necessary. Preferably, the lamination is performed by a so-called vacuum bonding method. Furthermore, it is preferable to perform a known pressure defoaming treatment on the laminate after the step (D) and before the step (E) (example of treatment conditions: 0.2 to 0.8 MPa, 25 to 60° C., 5 to 20 min) . <Step (E): Main Hardening Step> Next, the temporary hardening resin layer 5 sandwiched between the image display member 6 and the light-transmitting cover member 1 is irradiated with ultraviolet rays UV to be mainly hardened, thereby forming a transparent Photocurable resin layer 7 (FIG. 5). Thereby, the target image display device is obtained. In addition, the reason for carrying out the main hardening in this step is to fully harden the temporarily hardened resin layer 5 and to bond and laminate the image display member 6 and the translucent cover member 1 . The level of such a full hardening is such that the hardening rate (gel fraction) of the light-transmitting cured resin layer 7 is preferably at a level of 90% or more, more preferably 95% or more. In addition, regarding the level of the light transmittance of the light-transmitting cured resin layer 7 , the level of light-transmitting such that an image formed on the image display member 6 can be seen may be sufficient. [Examples] Hereinafter, the present invention will be specifically described with reference to examples. In addition, in the following examples, the total curing shrinkage, the temporary curing shrinkage, and the actual curing shrinkage of the photocurable resin composition were measured using an electronic hydrometer (SD-120L manufactured by Alfa Mirage Co., Ltd.). The specific gravity of the curable resin composition and the specific gravity of each of the temporarily cured product and the fully cured product were calculated by substituting these measurement results into the following formula. Total hardening shrinkage rate (%)=[(Specific gravity of completely hardened material - Specific gravity of unhardened composition)/Specific gravity of completely hardened material]×100 Temporary hardening shrinkage rate (%)=[(Specific gravity of temporary hardened material - Specific gravity of unhardened composition) /Specific gravity of temporary hardened product]×100 Full hardening shrinkage rate (%)=total hardening shrinkage rate−temporary hardening shrinkage rate Comparative Example 1 (step (A): coating step) First, prepare 45(w)×80(l) A transparent resin plate (polyethylene terephthalate plate) with a size of ×3(t) mm was bent by a known method so that the radius of curvature (r) in the width direction would be 300 mm to obtain a resin cover The cover (FIG. 1A) serves as a light-transmitting cover member in the shape of a curved transverse groove. In addition, 50 parts by mass of a (meth)acrylic oligomer having a polybutadiene skeleton (TE-2000, Nippon Soda Co., Ltd.), 20 parts by mass of hydroxyethyl methacrylate, and 10 parts by mass of a photopolymerization initiator Parts by mass (3 parts by mass of Irgacure 184 manufactured by BASF Japan Co., Ltd. and 7 parts by mass of SpeedCure TPO manufactured by DKSH Japan Co., Ltd.) were uniformly mixed to prepare a photocurable resin composition. The photocurable resin composition exhibits a total hardening shrinkage of 5.6% at a hardening rate of 0% to 90%. Next, two silicone rubber sheets are used as outer baffles to sandwich both ends of the resin cover in the shape of a transverse groove (Fig. 1G). The prepared photocurable resin composition was ejected from the concave portion of the resin cover using a resin dispenser so that the thickness of the central portion was 880 μm thick to form a photocurable resin composition film. (Step (B): Temporary Hardening Step) Next, the photocurable resin composition film was irradiated with an ultraviolet irradiation device (LC-8, Hamamatsu Photonics Co., Ltd.) so that the cumulative light amount would be 1200 mJ/cm 2 for 6 200 mW/cm 2 intensity of ultraviolet rays per second to temporarily harden the photocurable resin composition film to form a temporarily hardened resin layer, and to remove the outer stopper. At the time of temporary hardening, it was observed that minute recesses were formed in the center part of the temporary hardening resin layer ( FIG. 2B ). In addition, the temporary hardening shrinkage rate was 3.8%. In addition, the hardening rate of the temporary hardening resin layer was calculated|required using the absorption peak height of 1640-1620 cm-1 from the base line in the FT-IR measurement chart as an index, and it was found to be about 70%. (Step (D): Lamination Step) Next, the light transmittance obtained in Step (B) is applied to the surface of the flat liquid crystal display element with a size of 40 (W)×80 (L) mm on which the polarizer is laminated. The cover member was placed so that its temporarily hardened resin layer side became the polarizer side, and the resin cover was placed on the side by a vacuum laminating machine (vacuum degree 50 Pa, lamination pressure 0.07 MPa, lamination time 3 seconds, normal temperature) attached (Figure 4). (Step (E): Main Hardening Step) Next, the liquid crystal display element was irradiated with ultraviolet rays (200 mW/cm 2 ) at 3000 mJ/cm 2 using an ultraviolet irradiation device (ECS-03601EG, Eye Graphics Co., Ltd.) from the resin cover side. 2 ), whereby the temporarily hardened resin layer is completely hardened to form a light-transmitting hardened resin layer. The curing rate of the light-transmitting cured resin layer is 98%.

[Industrial Applicability] The method for producing an image display device of the present invention applies a photocurable resin composition to a concave surface of a curved transmissive cover member and performs temporary curing treatment, and then shrinks due to curing. Then, the photocurable resin composition is newly coated on the depression in the center portion of the temporarily cured resin layer, the image display member is laminated, and the main curing process is performed. Therefore, voids can be avoided on the display surface of the image display device, and the residual stress of the photocurable resin layer can be reduced without causing chromatic aberration in display. Therefore, the manufacturing method of this invention is useful for the industrial manufacture of the information terminal for vehicles provided with a touch panel.
