Abstract:
(EN) The purpose of the present invention is to provide a sealing agent for liquid crystal display elements which exhibits excellent application properties and curability under long-wavelength light, and which is capable of inhibiting a display failure which occurs when a liquid crystal display element is lit for a long period of time. Another purpose of the present invention is to provide a vertical conduction material and a liquid crystal display element which are obtained by using the sealing agent for liquid crystal display elements. This sealing agent for liquid crystal display elements includes a curable resin and a photopolymerization initiator. The curable resin includes a (meth)acrylic compound having a molecular weight in the range of 700-2000 inclusive. The photopolymerization initiator includes a compound having a structure represented by formula (1). In formula (1), * is a bonding position.
(FR) L'invention a pour objet de fournir un agent de scellement pour élément d'affichage à cristaux liquides présentant d'excellentes propriétés d'application et de durcissement à une lumière de longueur d'onde longue, et permettant d'inhiber des défauts d'affichage lors d'un allumage long d'un élément d'affichage à 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. Ainsi, l'invention concerne un agent de scellement pour élément d'affichage à cristaux liquides comprenant une résine durcissable et un initiateur de photopolymérisation. Ladite résine durcissable comprend un composé (méth)acrylique de masse moléculaire supérieure ou égale à 700 et inférieure ou égale à 2000. Ledit initiateur de photopolymérisation comprend un composé possédant une structure représentée par la formule (1). Dans la formule (1), * représente un site de liaison.
