Title (EN) SEALING AGENT FOR LIQUID CRYSTAL DISPLAY ELEMENTS, VERTICALLY CONDUCTING MATERIAL AND LIQUID CRYSTAL DISPLAY ELEMENT
(FR) AGENT DE SCELLEMENT POUR ÉLÉMENT D'AFFICHAGE À CRISTAUX LIQUIDES, MATÉRIAU À CONDUCTION VERTICALE, ET ÉLÉMENT D'AFFICHAGE À CRISTAUX LIQUIDES
(JA) 液晶表示素子用シール剤、上下導通材料、及び、液晶表示素子
Abstract:
(EN) One purpose of the present invention is to provide a sealing agent for liquid crystal display elements, which is capable of suppressing contamination of liquid crystals, while exhibiting excellent curability in a light-blocked part. Another purpose of the present invention is to provide: a vertically conducting material which is obtained using this sealing agent for liquid crystal display elements; and a liquid crystal display element. A sealing agent for liquid crystal display elements, which contains a curable resin and a radical photopolymerization initiator, and wherein: the curable resin contains a compound having a molecular weight of 100 or more but less than 500 and a compound having a molecular weight of 500-3,000; and the radical photopolymerization initiator is a compound having a carbazole skeleton.
(FR) L’invention a pour objet de fournir un agent de scellement pour élément d'affichage à cristaux liquides qui présente d’excellentes propriétés de durcissement de partie écran à la lumière, et qui permet d’empêcher une contamination de cristaux liquides. L'invention a également pour objet de fournir un élément d'affichage à cristaux liquides et un matériau à conduction verticale mettant en œuvre cet agent de scellement pour élément d'affichage à cristaux liquides. L’agent de scellement pour élément d'affichage à cristaux liquides comprend une résine durcissable et un initiateur de polymérisation par voie photoradicalaire. Ladite résine durcissable comprend un composé dont la masse moléculaire est supérieure ou égale à 100 et inférieure à 500, et un composé dont la masse moléculaire est comprise entre 500 et 3000. Ledit initiateur de polymérisation par voie photoradicalaire consiste en un composé possédant un squelette de carbazole.
(JA) 本発明は、遮光部硬化性に優れ、かつ、液晶汚染を抑制することができる液晶表示素子用シール剤を提供することを目的とする。また、本発明は、該液晶表示素子用シール剤を用いてなる上下導通材料及び液晶表示素子を提供することを目的とする。 硬化性樹脂と光ラジカル重合開始剤とを含有する液晶表示素子用シール剤であって、前記硬化性樹脂は、分子量が100以上500未満の化合物と、分子量が500~3000の化合物とを含有し、前記光ラジカル重合開始剤は、カルバゾール骨格を有する化合物である液晶表示素子用シール剤である。
