Abstract

L'invention concerne un matériau de scellement pour cristaux liquides, lequel matériau est excellent en termes d'adhérence, de fiabilité d'adhérence après avoir été exposé à des conditions d'humidité et de température élevées sur une longue durée, de caractéristiques électro-optiques de cristaux liquides, de maintien de l'alignement de cristaux liquides et de stabilité de viscosité lorsque ce matériau est appliqué au substrat d'un écran à cristaux liquides. Un matériau de scellement pour cristaux liquides selon l'invention comprend une résine époxy modifiée obtenue en faisant réagir une résine époxy avec un ester représenté par la formule générale (1), dans la mesure où la quantité d'ester utilisée lors de la réaction est inférieure à une mole par mole d'époxy de la résine époxy, formule (1) dans laquelle R1 représente hydrogène ou méthyle ; R2 représente hydrogène, alkyle, alcényle, halogéno, nitro ou méthoxy ; X désigne une liaison simple, alkylène ou un groupe représenté par la formule générale (A) ou (B), dans lesquelles R3 désigne alkylène).
