Title:
Liquid crystal seal adhesive and the liquid-crystal-display cell using it
Document Type and Number:
Japanese Patent JP6212055
Kind Code:
B2
Abstract:
Provided is a liquid-crystal sealing agent for a liquid-crystal dripping process having extremely low contamination of the liquid crystal throughout the step because of the speed of the reaction using heat, and having excellent handling properties and storage stability. This liquid-crystal sealing agent for a liquid-crystal dripping process contains: (a) a thermal radical polymerization initiator; (b) a radical polymerization preventing agent; (c) a curable resin having a (meth)acryloyl group; and (d) an organic filler, component (b) being expressed by any of formulas (1)-(3), or having a piperidine skeleton. In the formulas, R1, R2, R4, and R5 represent a hydrogen atom or a methyl group, and R3 and R6 represent a hydroxy group or a C1-4 alkyl group. Note that one of -OR1, -OR2, and -R3, and one of -OR4, -OR5, and -R6 is a hydroxy group. R7 represents a hydrogen atom, a hydroxy group, or a C1-4 alkyl group.
