Description

積層體之製造方法及光硬化性樹脂組合物Method for producing laminated body and photocurable resin composition

本技術係關於一種積層體之製造方法及光硬化性樹脂組合物。本申請案係以在日本於2017年2月28日提出申請之日本專利申請案編號特願2017-037614為基礎並主張優先權者，且將該申請案藉由參照而引用至本申請案中。This technology relates to a method for producing a laminate and a photocurable resin composition. The present application is based on Japanese Patent Application No. 2017-037614, the entire disclosure of which is hereby incorporated by .

先前，已知有將構件彼此藉由光硬化性樹脂組合物貼合，藉由透光性樹脂層固定之技術。例如，於例如專利文獻1中，記載有於圖像顯示構件與透光性構件之間配置光硬化性樹脂組合物而形成樹脂組合物層，對樹脂組合物層照射光而形成硬化樹脂層之方法。此處，較理想為圖像顯示裝置中之透光性構件與圖像顯示構件之密接性良好。 又，就抑制光硬化性樹脂組合物自被塗佈體(透光性構件或圖像顯示構件)溢出之觀點而言，存在採用所謂障壁填充製程之情況。於障壁填充製程中，例如使用第1樹脂組合物(障壁材料)，於圖像顯示構件之表面形成第2樹脂組合物(填充材料)之塗佈區域。其次，於所形成之塗佈區域塗佈第2樹脂組合物，使圖像顯示構件與透光性構件經由第2樹脂組合物貼合。然後，對第2樹脂組合物照射光而形成硬化樹脂層。 於障壁填充製程中，就防滴液之觀點而言，障壁材料較佳為高黏度。另一方面，就防止氣泡而以較短之產距時間貼合之觀點而言，填充材料較佳為低黏度。此處，為了使障壁材料與填充材料之邊界部之視認性良好，即為了使障壁材料與填充材料之邊界線不明顯，存在使用同一成分之樹脂組合物作為障壁材料與填充材料之情況。然而，若使用同一成分之樹脂組合物作為障壁材料與填充材料，則有會犧牲障壁材料之高黏度性、或填充材料之低黏度性之顧慮。 [先前技術文獻] [專利文獻] [專利文獻1]日本專利特開2014-222350號公報Heretofore, a technique in which members are bonded to each other by a photocurable resin composition and fixed by a translucent resin layer is known. For example, Patent Document 1 discloses that a photocurable resin composition is disposed between an image display member and a translucent member to form a resin composition layer, and the resin composition layer is irradiated with light to form a cured resin layer. method. Here, it is preferable that the adhesion between the light transmissive member and the image display member in the image display device is good. In addition, from the viewpoint of suppressing the overflow of the photocurable resin composition from the object to be coated (translucent member or image display member), there is a case where a so-called barrier filling process is employed. In the barrier filling process, for example, a coating region of the second resin composition (filler) is formed on the surface of the image display member using the first resin composition (barrier material). Next, the second resin composition is applied to the formed coating region, and the image display member and the light transmissive member are bonded together via the second resin composition. Then, the second resin composition is irradiated with light to form a cured resin layer. In the barrier filling process, the barrier material is preferably high in viscosity from the viewpoint of drip prevention. On the other hand, the filler material preferably has a low viscosity from the viewpoint of preventing the bubbles from being bonded at a shorter production time. Here, in order to make the visibility of the boundary portion between the barrier material and the filler material good, that is, in order to make the boundary between the barrier material and the filler material inconspicuous, there is a case where a resin composition of the same composition is used as the barrier material and the filler. However, if a resin composition of the same composition is used as the barrier material and the filler, there is a concern that the high viscosity of the barrier material or the low viscosity of the filler material is sacrificed.

In the case of the filler material, the high viscosity of the barrier material and the low viscosity of the filler material are also taken into consideration, and the adhesion between the members is good. [Means for Solving the Problem] The method for producing a laminate according to the present invention includes the step (A) of forming a coating region of the second resin composition which is photocurable using the first resin composition on the surface of the first member. a step (B) of applying a second resin composition to the coating region, and a step (C) of bonding the first member and the second member to the second resin composition to form the second resin composition Filled in the coating region; and step (D), the second resin composition is irradiated with light to form a cured resin layer; and the step (C) includes heating the second resin composition, and the second resin composition is contained in After heating at 60 ° C for 30 minutes, the heating residue was 95.0% or more of the monofunctional monomer, and the second resin composition was heated at 80 ° C for 3 hours, and the heating residue was 95.0% or more. The photocurable resin composition of the present invention contains a monofunctional monomer, a (meth) acrylate resin, a photopolymerization initiator, and a plasticizer having a heating residue of 95.0% or more after heating at 60 ° C for 30 minutes. The heating residue after heating at 80 ° C for 3 hours was 95.0% or more. [Effects of the Invention] According to the present technology, even when the resin composition of the same composition is used as the first resin composition (barrier material) and the second resin composition (filler), the high viscosity of the barrier material is also considered. The low viscosity with the filler material allows the members to have good adhesion to each other.

[積層體之製造方法] 本實施形態之積層體之製造方法具有下述步驟(A)～(D)，且步驟(C)包括將第2樹脂組合物進行加熱。又，本製造方法中所使用之第2樹脂組合物如後文所詳述，含有於60℃下加熱30分鐘後之加熱殘分為95.0%以上之單官能單體，且於80℃下加熱3小時後之加熱殘分為95.0%以上。 步驟(A)：於第1構件之表面使用第1樹脂組合物形成光硬化性之第2樹脂組合物之塗佈區域。 步驟(B)：於塗佈區域塗佈第2樹脂組合物。 步驟(C)：使第1構件與第2構件經由第2樹脂組合物貼合，使第2樹脂組合物填充於塗佈區域。 步驟(D)：對第2樹脂組合物照射光而形成硬化樹脂層。 根據本製造方法，於步驟(C)中將第2樹脂組合物進行加熱，藉此可降低第2樹脂組合物之黏度。因此，即便於使用同一成分之樹脂組合物作為第1樹脂組合物與第2樹脂組合物之情形時，亦可兼顧第1樹脂組合物之高黏度性與第2樹脂組合物之低黏度性。又，於本製造方法中，使用於80℃下加熱3小時後之加熱殘分為95.0%以上之第2樹脂組合物，藉此於將第2樹脂組合物進行加熱時，可抑制第2樹脂組合物中之成分之揮發，因此可使第1構件與第2構件之密接性良好。 本製造方法中所使用之第2樹脂組合物於80℃下加熱3小時後之加熱殘分為95.0%以上，較佳為97.0%以上，更佳為98.0%以上，進而較佳為99.0%以上。藉由使加熱殘分更多，於將第2樹脂組合物進行加熱時，可更有效地抑制第2樹脂組合物中之成分之揮發。又，第2樹脂組合物之加熱殘分之上限值並無特別限制。此處，第2樹脂組合物之加熱殘分係指使用熱量計測定裝置(裝置名：Q50，TA Instruments公司製造)測定樹脂組合物10 mg於80℃下加熱3小時前後之質量而求出之值。關於第2樹脂組合物之詳情，將於後文進行敍述。 以下，一面參照圖式一面對各步驟之詳情進行說明。於本製造方法中，例如如圖1所示，獲得圖像顯示構件2(第1構件)與周緣部形成有遮光層4之透光性構件3(第2構件)經由硬化樹脂層1積層而成之圖像顯示裝置5(積層體)。

圖像顯示構件2例如可列舉液晶顯示面板、觸控面板等。此處，所謂觸控面板，意指將如液晶顯示面板之顯示元件與如觸控板之位置輸入裝置組合而成之圖像顯示、輸入面板。 透光性構件3為具有能夠視認形成於圖像顯示構件2之圖像之透光性者即可。例如可列舉：玻璃、丙烯酸樹脂、聚對苯二甲酸乙二酯、聚萘二甲酸乙二酯、聚碳酸酯等板狀材料或片狀材料。對於該等材料，亦可於至少一面實施硬塗處理、抗反射處理等。透光性構件3之厚度或彈性模數等物性可根據使用目的適當決定。 遮光層4係為了提高圖像之對比度而設置者，例如可藉由網版印刷法等塗佈著色為黑色等之塗料，並使其乾燥、硬化而形成。遮光層4之厚度通常為5～100 μm。 [步驟(A)] 於步驟(A)中，例如如圖2、3所示，於圖像顯示構件2之表面使用第1樹脂組合物6形成第2樹脂組合物8之塗佈區域7。塗佈區域7係例如如圖3、4所示，圖像顯示構件2之顯示區域中被由第1樹脂組合物6形成之框狀之阻液部(障壁)11包圍之區域。 第1樹脂組合物6係用於防止於步驟(B)中塗佈於塗佈區域7之第2樹脂組合物8之滴液之材料。第1樹脂組合物6例如可使用熱硬化性之樹脂組合物、光硬化性(例如紫外線硬化性)之樹脂組合物等。於第1樹脂組合物6為光硬化性之樹脂組合物之情形時，於步驟(A)中，例如如圖4所示，對第1樹脂組合物6自紫外線照射器9照射紫外線10，使第1樹脂組合物6硬化，形成阻液部11，藉此可劃定塗佈區域7。 就防滴液之觀點而言，第1樹脂組合物6較佳為高黏度。例如，第1樹脂組合物6較佳為於25℃下之黏度為10000～50000 mPa・s。 第1樹脂組合物6之塗佈方法可採用各種塗佈方法，例如可列舉使用分注器之方法、使用塗佈機之方法、使用噴霧器之方法等。就抑制滴液之觀點而言，尤佳為使用分注器之方法。第1樹脂組合物6之塗佈厚度例如可設為於本製造方法之步驟(B)中塗佈於塗佈區域7之第2樹脂組合物8之厚度以下。 [步驟(B)] 於步驟(B)中，例如如圖5所示，於塗佈區域7塗佈第2樹脂組合物8。作為第2樹脂組合物8之塗佈方法，可採用各種塗佈方法，例如可列舉上述之第1樹脂組合物6之塗佈方法。又，第2樹脂組合物8之塗佈量例如較佳為設為於步驟(C)中之貼合時可填充於塗佈區域7之量。 第2樹脂組合物8較佳為於步驟(D)中硬化時，與由第1樹脂組合物6形成之阻液部11之邊界線於目視下不明顯。因此，第2樹脂組合物8較佳為與第1樹脂組合物6實質上為同一成分。所謂同一成分，意指至少第1樹脂組合物6與第2樹脂組合物8之光學特性相同，例如透光率及折射率實質上相等。於第1樹脂組成6與第2樹脂組合物8之光學特性實質上相等之情形時，例如即便第1樹脂組合物6與第2樹脂組合物8之黏度不同，亦包含於同一成分。 又，就防止氣泡而以較短之產距時間貼合之觀點而言，第2樹脂組合物8較佳為於步驟(C)中之貼合時為低黏度。例如，第2樹脂組合物8較佳為於貼合時之溫度下之黏度為3000 mPa・s以下，更佳為1000～3000 mPa・s。 於本製造方法中，於以下之步驟(C)中將第2樹脂組合物8進行加熱(加溫)，藉此可將第2樹脂組合物8之黏度調整為低黏度(例如3000 mPa・s以下)。因此，即便於使用同一成分之樹脂組合物作為第1樹脂組合物6與第2樹脂組合物8之情形時，亦可兼顧第1樹脂組合物6之高黏度性與第2樹脂組合物8之低黏度性。 又，於本製造方法中，藉由使用於80℃下加熱3小時後之加熱殘分為95.0%以上之第2樹脂組合物8，於以下之步驟(C)中將第2樹脂組合物8進行加熱時，可抑制第2樹脂組合物8中之成分(例如後述之單官能單體)之揮發。因此，可使透光性構件3與圖像顯示構件2之密接性良好。 [步驟(C)] 於步驟(C)中，例如如圖6所示，將圖像顯示構件2與透光性構件3經由第2樹脂組合物8貼合，使第2樹脂組合物8填充於塗佈區域7。圖像顯示構件2與透光性構件3之貼合例如可使用公知之壓接裝置進行。 又，步驟(C)包括如上所述般將第2樹脂組合物8進行加熱。藉由將第2樹脂組合物8進行加熱，於使第2樹脂組合物8減黏之狀態下填充於塗佈區域7。藉此，可防止第2樹脂組合物8中之氣泡而以較短之產距時間貼合。加熱條件較佳為設定為可將第2樹脂組合物8之黏度調整為低黏度(例如例如3000 mPa・s以下)。例如，加熱溫度係考慮熱對圖像顯示構件2或透光性構件3之影響而較佳為80℃以下，更佳為60～80℃。加熱時間例如可設為30分鐘～3小時左右。關於加熱之時點，可於圖像顯示構件2與透光性構件3之貼合前進行，可於貼合時進行，亦可於貼合後進行。作為加熱方法，例如可列舉使用加熱器等之方法等。 [步驟(D)] 於步驟(D)中，例如如圖7所示，對第2樹脂組合物8自紫外線照射器9照射紫外線10，形成硬化樹脂層1(參照圖1)。步驟(D)中之光照射較佳為使於步驟(C)中加熱之第2樹脂組合物8散熱後進行。 此處，於第2樹脂組合物8與第1樹脂組合物6實質上為同一成分之情形時，光照射後之第2樹脂組合物8與阻液部11一體化，成為光學上具有相同性質之單一之硬化樹脂層1。藉此，可使阻液部11與硬化後之第2樹脂組合物8之邊界部之視認性更良好。 如上所述，根據本製造方法，於步驟(C)中將第2樹脂組合物8進行加熱，藉此第2樹脂組合物8之黏度降低。因此，即便於使用同一成分之樹脂組合物作為第1樹脂組合物6與第2樹脂組合物8之情形時，亦可兼顧第1樹脂組合物6之高黏度性與第2樹脂組合物8之低黏度性。又，於本製造方法中，使用光硬化性樹脂組合物作為第2樹脂組合物8，該光硬化性樹脂組合物含有於60℃下加熱30分鐘後之加熱殘分為95.0%以上之單官能單體，且於80℃下加熱3小時後之加熱殘分為95.0%以上。藉此，於將第2樹脂組合物8進行加熱時，可抑制第2樹脂組合物8中之成分之揮發，而使透光性構件3與圖像顯示構件2之密接性良好。 再者，上述之製造方法係於圖像顯示構件2之表面塗佈第1樹脂組合物6與第2樹脂組合物8，但並不限定於該方法。例如，亦可於透光性構件3之表面塗佈第1樹脂組合物6與第2樹脂組合物8。又，於上述之製造方法中，使用形成有遮光層4之透光性構件3，但並不限定於該例。例如，亦可使用未形成遮光層之透光性構件。 又，於上述之步驟(A)中，藉由光照射使光硬化性之樹脂組合物6硬化而形成阻液部11，但並不限定於該方法。例如，於步驟(A)中，亦可使用熱硬化性之第1樹脂組合物6，將第1樹脂組合物6進行加熱而使其硬化，從而形成阻液部11。又，於第1樹脂組合物6之黏度足夠高至可防止第2樹脂組合物8之滴液之情形時，亦可不藉由熱或光使第1樹脂組合物6硬化。 [光硬化性樹脂組合物]

藉由光硬化性樹脂組合物含有上述之單官能單體，於上述之步驟(C)中將第2樹脂組合物進行加熱時，可更有效地抑制該單官能單體之揮發。因此，可使透光性構件3與圖像顯示構件2之密接性更良好。 具體而言，單官能單體較佳為單官能(甲基)丙烯酸酯，例如較佳為式(A)所表示之化合物及式(B)所表示之化合物之至少1種。 [化1]式(A)中，R1 表示氫原子或甲基。R2 表示碳數2或3之伸烷基。R3

按照表1所示之調配量(質量份)將各成分均勻混合而製備光硬化性樹脂組合物。 [光硬化性樹脂組合物之黏度] 藉由流變儀(RS600，HAAKE公司製造，錐角度C35/2°)，測定光硬化性樹脂組合物於25℃或80℃下之黏度。 [光硬化性樹脂組合物之折射率] 使用阿貝折射率計(鈉D射線(585 nm)，25℃)，測定各光硬化性樹脂組合物於80℃下加熱3小時後之折射率、及加熱前之折射率。 [光硬化性樹脂組合物之加熱殘分] 各光硬化性樹脂組合物之加熱殘分(%)係使用熱量計測定裝置(裝置名：Q50，TA Instruments公司製造)而求出。具體而言，如圖9所示，於容器14中放入10 mg之光硬化性樹脂組合物15，測定光硬化性樹脂組合物15於80℃下加熱3小時前後之質量，藉此而求出。 [不將光硬化性樹脂組合物進行加熱之情形時之接著強度] 如圖10、圖11所示，於厚度1.1 mm之玻璃板16之中央部滴加光硬化性樹脂組合物，介隔0.15 mm之間隔件19，以正交之方式載置厚度1.1 mm之玻璃板17。藉此，獲得於玻璃板16、17之間形成有直徑6 mm、厚度0.15 mm之樹脂組合物層18之玻璃接合體20。 如圖12、圖13所示，使用紫外線照射器9，以累計光量成為5000 mJ/cm2 之方式，自玻璃板17側照射紫外線10，使樹脂組合物層18硬化，形成硬化樹脂層21。 如圖14所示，將玻璃接合體20之玻璃板16、17由治具22A、22B固定，並且自治具22B側於垂直方向以5 mm/分鐘之速度壓入，按照以下之基準評價接著狀態。接著強度之測定使用負載試驗機(JSV-1000，日本計測系統公司製造)。接著強度係藉由下述方式而算出，即，測定於25℃下至玻璃板16與玻璃板17分離所需之應力，將該應力除以硬化樹脂層21之單位面積。 [將光硬化性樹脂組合物進行加熱之情形時之接著強度] 使用於80℃下加熱3小時者作為滴加至玻璃板16之光硬化性樹脂組合物，除此以外，與上述之不將光硬化性樹脂組合物進行加熱之情形時之接著強度之測定同樣地進行。 [透過率] 使用紫外可見分光光度計(島津製作所製造，UV-2450)，測定玻璃接合體20中之硬化樹脂層21之可見光區域之透過率。就實用性而言，硬化樹脂層21之透過率較佳為90%以上。 [表1] 實施例之光硬化性樹脂組合物藉由加熱而黏度降低。因此，於障壁填充製程中，即便於使用同一成分之樹脂組合物作為障壁材料(第1樹脂組合物)與填充材料(第2樹脂組合物)之情形時，亦可兼顧障壁材料之高黏度性與填充材料之低黏度性。 又，實施例之光硬化性樹脂組合物含有於60℃下加熱30分鐘後之加熱殘分為95.0%以上之單官能單體，且於80℃下加熱3小時後之加熱殘分為95.0%以上。因此，可知即便於預先將硬化性樹脂組合物加熱之情形時，接著強度亦良好。藉此，例如於障壁填充製程中，於將填充材料進行加熱時，可抑制填充材料中之成分之揮發，可使構件彼此之密接性良好。 另一方面，可知於使用於80℃下加熱3小時後之加熱殘分未達95.0%之樹脂組合物之比較例1、2中，於預先將樹脂組合物加熱之情形時，接著強度不良。因此，例如於障壁填充製程中，於將填充材料進行加熱時，無法抑制填充材料中之成分之揮發，難以使構件彼此之密接性良好。又，可知於比較例3、4中，由於使用不含有於60℃下加熱30分鐘後之加熱殘分為95.0%以上之單官能單體之樹脂組合物作為樹脂組合物，故而接著強度不良。[Manufacturing Method of Laminate] The method for producing a laminate of the present embodiment has the following steps (A) to (D), and the step (C) includes heating the second resin composition. Moreover, the second resin composition used in the present production method contains a monofunctional monomer having a heating residue of 95.0% or more after heating at 60 ° C for 30 minutes as described in detail later, and is heated at 80 ° C. The heating residue after 3 hours was 95.0% or more. Step (A): The coating region of the photocurable second resin composition is formed on the surface of the first member using the first resin composition. Step (B): applying the second resin composition to the coating region. Step (C): The first member and the second member are bonded together via the second resin composition, and the second resin composition is filled in the coating region. Step (D): The second resin composition is irradiated with light to form a cured resin layer. According to the production method, the second resin composition is heated in the step (C), whereby the viscosity of the second resin composition can be lowered. Therefore, even when the resin composition of the same component is used as the first resin composition and the second resin composition, the high viscosity of the first resin composition and the low viscosity of the second resin composition can be achieved. Further, in the present production method, the second resin composition having a heating residual of 95.0% or more after heating at 80 ° C for 3 hours is used, whereby the second resin can be suppressed when the second resin composition is heated. Since the components in the composition are volatilized, the adhesion between the first member and the second member can be improved. The heating residue of the second resin composition used in the production method after heating at 80 ° C for 3 hours is 95.0% or more, preferably 97.0% or more, more preferably 98.0% or more, still more preferably 99.0% or more. . When the second resin composition is heated by heating more, the volatilization of the components in the second resin composition can be more effectively suppressed. Further, the upper limit of the heating residue of the second resin composition is not particularly limited. Here, the heating residue of the second resin composition is obtained by measuring the mass of 10 mg of the resin composition heated at 80 ° C for 3 hours using a calorimeter measuring device (device name: Q50, manufactured by TA Instruments). value. Details of the second resin composition will be described later. Hereinafter, the details of each step will be described with reference to the drawings. In the present manufacturing method, for example, as shown in FIG. 1 , the image display member 2 (first member) and the light transmissive member 3 (second member) having the light shielding layer 4 formed on the peripheral portion thereof are laminated via the cured resin layer 1 . The image display device 5 (layered body). The cured resin layer 1 is formed of a first resin composition 6 and a second resin composition 8 which will be described later. The refractive index of the cured resin layer 1 is preferably substantially the same as the refractive index of the image display member 2 or the light-transmitting member 3, and is preferably, for example, 1.45 or more and 1.55 or less. Thereby, the brightness or contrast of the image light from the image display member 2 can be improved, and visibility can be improved. Further, the transmittance of the cured resin layer 1 is preferably more than 90%. Thereby, the visibility of the image formed on the image display member 2 can be made better. The thickness of the cured resin layer 1 is preferably, for example, 50 to 200 μm. Examples of the image display member 2 include a liquid crystal display panel, a touch panel, and the like. Here, the touch panel means an image display and input panel in which a display element such as a liquid crystal display panel and a position input device such as a touch panel are combined. The light transmissive member 3 may have a light transmissive property capable of visually recognizing an image formed on the image display member 2. For example, a plate-shaped material or a sheet material such as glass, acrylic resin, polyethylene terephthalate, polyethylene naphthalate or polycarbonate may be mentioned. For these materials, hard coating treatment, anti-reflection treatment, or the like may be performed on at least one side. The physical properties such as the thickness of the light transmissive member 3 or the modulus of elasticity can be appropriately determined depending on the purpose of use. The light shielding layer 4 is provided to increase the contrast of the image, and can be formed by, for example, coating a black paint such as a screen printing method, drying it, and curing it. The thickness of the light shielding layer 4 is usually 5 to 100 μm. [Step (A)] In the step (A), for example, as shown in Figs. 2 and 3, the coating region 7 of the second resin composition 8 is formed on the surface of the image display member 2 using the first resin composition 6. The coating region 7 is a region surrounded by a frame-shaped liquid-repellent portion (barrier) 11 formed of the first resin composition 6 in the display region of the image display member 2, for example, as shown in FIGS. The first resin composition 6 is a material for preventing the dripping of the second resin composition 8 applied to the coating region 7 in the step (B). For the first resin composition 6, for example, a thermosetting resin composition, a resin composition having photocurability (for example, ultraviolet curability), or the like can be used. In the case where the first resin composition 6 is a photocurable resin composition, in the step (A), for example, as shown in FIG. 4, the first resin composition 6 is irradiated with ultraviolet rays 10 from the ultraviolet ray irradiator 9, so that The first resin composition 6 is cured to form a liquid-repellent portion 11, whereby the coating region 7 can be defined. The first resin composition 6 is preferably high in viscosity from the viewpoint of drip prevention. For example, the first resin composition 6 preferably has a viscosity at 25 ° C of 10,000 to 50,000 mPa·s. The coating method of the first resin composition 6 can be carried out by various coating methods, and examples thereof include a method using a dispenser, a method using a coater, a method using a sprayer, and the like. In terms of suppressing dripping, it is particularly preferable to use a dispenser. The coating thickness of the first resin composition 6 can be, for example, less than the thickness of the second resin composition 8 applied to the coating region 7 in the step (B) of the present production method. [Step (B)] In the step (B), for example, as shown in FIG. 5, the second resin composition 8 is applied to the coating region 7. As a coating method of the second resin composition 8, various coating methods can be employed, and for example, the coating method of the above-described first resin composition 6 can be mentioned. Moreover, it is preferable that the coating amount of the second resin composition 8 is, for example, an amount which can be filled in the coating region 7 at the time of bonding in the step (C). The second resin composition 8 is preferably not visually observed when it is hardened in the step (D) and the boundary line of the liquid-repellent portion 11 formed of the first resin composition 6. Therefore, the second resin composition 8 is preferably substantially the same component as the first resin composition 6. The same component means that at least the optical properties of the first resin composition 6 and the second resin composition 8 are the same, and for example, the light transmittance and the refractive index are substantially equal. When the optical properties of the first resin composition 6 and the second resin composition 8 are substantially equal, for example, even if the viscosity of the first resin composition 6 and the second resin composition 8 are different, they are included in the same component. Further, from the viewpoint of preventing the bubbles from being bonded at a short production time, the second resin composition 8 preferably has a low viscosity at the time of bonding in the step (C). For example, the second resin composition 8 preferably has a viscosity at a temperature at the time of bonding of 3,000 mPa·s or less, more preferably 1,000 to 3,000 mPa·s. In the present production method, the second resin composition 8 is heated (warmed) in the following step (C), whereby the viscosity of the second resin composition 8 can be adjusted to a low viscosity (for example, 3000 mPa·s). the following). Therefore, even when the resin composition of the same component is used as the first resin composition 6 and the second resin composition 8, the high viscosity of the first resin composition 6 and the second resin composition 8 can be achieved. Low viscosity. Further, in the present production method, the second resin composition 8 is heated in the following step (C) by using the second resin composition 8 having a heating residue of 95.0% or more after heating at 80 ° C for 3 hours. When heating is performed, volatilization of a component (for example, a monofunctional monomer described later) in the second resin composition 8 can be suppressed. Therefore, the adhesion between the light transmissive member 3 and the image display member 2 can be improved. [Step (C)] In the step (C), for example, as shown in FIG. 6, the image display member 2 and the light transmissive member 3 are bonded together via the second resin composition 8, and the second resin composition 8 is filled. In the coating area 7. The bonding of the image display member 2 and the light transmissive member 3 can be performed, for example, using a known pressure bonding device. Further, the step (C) includes heating the second resin composition 8 as described above. By heating the second resin composition 8, the second resin composition 8 is filled in the coating region 7 while being viscous. Thereby, the bubbles in the second resin composition 8 can be prevented from being bonded at a short production time. The heating condition is preferably set so that the viscosity of the second resin composition 8 can be adjusted to a low viscosity (for example, 3,000 mPa·s or less). For example, the heating temperature is preferably 80 ° C or less, more preferably 60 to 80 ° C, in consideration of the influence of heat on the image display member 2 or the light transmissive member 3. The heating time can be, for example, about 30 minutes to 3 hours.

Examples of the heating method include a method using a heater or the like. [Step (D)] In the step (D), for example, as shown in Fig. 7, the second resin composition 8 is irradiated with ultraviolet rays 10 from the ultraviolet ray irradiator 9 to form a cured resin layer 1 (see Fig. 1). The light irradiation in the step (D) is preferably carried out after the second resin composition 8 heated in the step (C) is radiated. When the second resin composition 8 and the first resin composition 6 are substantially the same component, the second resin composition 8 after light irradiation is integrated with the liquid-repellent portion 11 to have optically identical properties. A single hardened resin layer 1. Thereby, the visibility of the boundary portion between the liquid-repellent portion 11 and the cured second resin composition 8 can be made better. As described above, according to the production method, the second resin composition 8 is heated in the step (C), whereby the viscosity of the second resin composition 8 is lowered. Therefore, even when the resin composition of the same component is used as the first resin composition 6 and the second resin composition 8, the high viscosity of the first resin composition 6 and the second resin composition 8 can be achieved. Low viscosity. Moreover, in the manufacturing method, the photocurable resin composition is used as the second resin composition 8, and the photocurable resin composition contains a monofunctional group having a heating residue of 95.0% or more after heating at 60 ° C for 30 minutes.

When the second resin composition 8 is heated, the volatilization of the components in the second resin composition 8 can be suppressed, and the adhesion between the translucent member 3 and the image display member 2 can be improved. Further, in the above-described manufacturing method, the first resin composition 6 and the second resin composition 8 are applied to the surface of the image display member 2, but the method is not limited thereto. For example, the first resin composition 6 and the second resin composition 8 may be applied to the surface of the light transmissive member 3. Further, in the above-described manufacturing method, the light transmissive member 3 in which the light shielding layer 4 is formed is used, but the invention is not limited thereto. For example, a light transmissive member in which a light shielding layer is not formed may also be used. Further, in the above step (A), the photocurable resin composition 6 is cured by light irradiation to form the liquid-repellent portion 11, but the method is not limited thereto. For example, in the step (A), the first resin composition 6 which is thermosetting can be used, and the first resin composition 6 is heated and hardened to form the liquid-repellent portion 11. Further, when the viscosity of the first resin composition 6 is sufficiently high to prevent the dropping of the second resin composition 8, the first resin composition 6 may not be cured by heat or light.

[Polymerization start Irg184: 1-hydroxycyclohexyl phenyl ketone, manufactured by BASF Corporation [heating residue of monofunctional monomer] The heating residue (%) of each monofunctional monomer is a calorimeter measuring device (device name: Q50, It was obtained by TA Instruments. Specifically, as shown in FIG. 8, 10 mg of the monofunctional monomer 13 was placed in the container 12, and the mass of the monofunctional monomer 13 heated at 60 ° C for 30 minutes was measured. [Preparation of Photocurable Resin Composition] Each component was uniformly mixed according to the blending amount (parts by mass) shown in Table 1 to prepare a photocurable resin composition. [Viscosity of Photocurable Resin Composition] The viscosity of the photocurable resin composition at 25 ° C or 80 ° C was measured by a rheometer (RS600, manufactured by HAAKE Co., Ltd., taper angle C35/2°). [Refractive Index of Photocurable Resin Composition] The refractive index of each photocurable resin composition after heating at 80 ° C for 3 hours was measured using an Abbe refractometer (sodium D-ray (585 nm), 25 ° C). And the refractive index before heating. [The heating residue of the photocurable resin composition] The heating residue (%) of each photocurable resin composition was determined using a calorimeter measuring device (device name: Q50, manufactured by TA Instruments). Specifically, as shown in FIG. 9, 10 mg of the photocurable resin composition 15 was placed in the container 14, and the mass of the photocurable resin composition 15 was heated at 80 ° C for 3 hours, thereby obtaining Out. [Bottom strength when the photocurable resin composition is not heated] As shown in Figs. 10 and 11, the photocurable resin composition is dropped at a central portion of the glass plate 16 having a thickness of 1.1 mm, and is separated by 0.15. The spacer 19 of mm is placed with a glass plate 17 having a thickness of 1.1 mm in an orthogonal manner. Thereby, a glass bonded body 20 in which a resin composition layer 18 having a diameter of 6 mm and a thickness of 0.15 mm was formed between the glass sheets 16 and 17 was obtained. As shown in FIG. 12 and FIG. 13 , the ultraviolet ray irradiator 9 is used to irradiate the ultraviolet ray 10 from the side of the glass plate 17 so that the cumulative amount of light becomes 5000 mJ/cm 2 , and the resin composition layer 18 is cured to form the cured resin layer 21 . As shown in Fig. 14, the glass plates 16, 17 of the glass joined body 20 were fixed by the jigs 22A and 22B, and the side of the autonomous device 22B was pressed at a speed of 5 mm/min in the vertical direction, and the subsequent state was evaluated according to the following criteria. . Next, the strength was measured using a load tester (JSV-1000, manufactured by Nippon Measurement Systems Co., Ltd.). Then, the strength was calculated by measuring the stress required to separate the glass plate 16 from the glass plate 17 at 25 ° C, and dividing the stress by the unit area of the cured resin layer 21. [Bottom strength in the case of heating the photocurable resin composition] The photocurable resin composition which is added to the glass plate 16 when heated at 80 ° C for 3 hours is not the same as the above. The measurement of the adhesive strength in the case where the photocurable resin composition was heated was carried out in the same manner. [Transmittance] The transmittance in the visible light region of the cured resin layer 21 in the glass joined body 20 was measured using an ultraviolet-visible spectrophotometer (UV-2450, manufactured by Shimadzu Corporation). The transmittance of the cured resin layer 21 is preferably 90% or more in terms of practicality. [Table 1] The photocurable resin composition of the example has a reduced viscosity by heating. Therefore, even in the case of using the resin composition of the same composition as the barrier material (first resin composition) and the filler (second resin composition) in the barrier filling process, the high viscosity of the barrier material can be achieved. Low viscosity with filler material. Further, the photocurable resin composition of the example contains a monofunctional monomer having a heating residual of 95.0% or more after heating at 60 ° C for 30 minutes, and a heating residue of 95.0% after heating at 80 ° C for 3 hours. the above. Therefore, it is understood that the strength is good even when the curable resin composition is heated in advance. Thereby, for example, in the barrier filling process, when the filler is heated, volatilization of the components in the filler can be suppressed, and the adhesion between the members can be improved. On the other hand, in Comparative Examples 1 and 2, which were used in a resin composition having a heating residue of not more than 95.0% after heating at 80 ° C for 3 hours, when the resin composition was heated in advance, the strength was poor. Therefore, for example, in the barrier filling process, when the filler is heated, volatilization of components in the filler cannot be suppressed, and it is difficult to make the components adhere well. In addition, in Comparative Examples 3 and 4, a resin composition which does not contain a monofunctional monomer having a heating residue of 95.0% or more after heating at 60 ° C for 30 minutes was used as the resin composition, and thus the strength was poor.
