Abstract:
(EN) One purpose of the present invention is to provide a sealing agent for liquid crystal display elements, which enables the achievement of a liquid crystal display element that has excellent bonding properties, low possibility of contaminating liquid crystals and excellent display performance. 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. The present invention is a sealing agent for liquid crystal display elements, which contains a curable resin and a polymerization initiator and/or a thermal curing agent, and wherein: the curable resin contains a compound represented by formula (1) and a compound having two or more epoxy groups in each molecule; the content of the compound having two or more epoxy groups in each molecule in 100 parts by weight of the curable resin is from 5 parts by weight to 25 parts by weight (inclusive); and a cured product of this sealing agent for liquid crystal display elements has a bonding strength of 290 N/cm2 or more with respect to a glass substrate. In formula (1), R1 represents a hydrogen atom or a methyl group; R2 represents a group represented by formula (2-1) or formula (2-2); R3 represents a structure derived from an acid anhydride; R4 represents a structure derived from an epoxy compound; X represents a ring-opened structure of a lactone; n represents an integer of 1-6; and a represents an integer of 1-4. In formula (2-1), * represents a bonding position. In formula (2-2), b represents an integer of 0-8; c represents an integer of 0-3; d represents an integer of 0-8; e represents an integer of 0-8; one of b, c and d is 1 or more; and * represents a bonding position.
(FR) La présente invention concerne un agent d'étanchéité pour des éléments d'affichage à cristaux liquides, présentant d'excellentes propriétés de liaison, une faible probabilité de contamination des cristaux liquides et d'excellentes performances d'affichage. L'invention concerne également : un matériau à conduction verticale obtenu au moyen de cet agent d’étanchéité pour éléments d'affichage à cristaux liquides ; ainsi qu'un élément d’affichage à cristaux liquides.
