Abstract

Disclosed is a liquid crystal sealing agent having long working life and excellent coatability to substrates, which is accelerated in the curing reaction of a resin, thereby increasing adhesiveness while suppressing contamination of liquid crystals by the resin. Specifically disclosed is a liquid crystal sealing agent containing (a) a polyvalent carboxylic acid having an isocyanuric ring structure represented by the general formula (1) below, (b) a curable resin composed of an epoxy resin and / or a (meth)acrylated epoxy resin, (c) a thermosetting agent, and (d) an inorganic filler. (In the formula (1), R1-R3 independently represent a hydrogen atom or a group represented by the following formula (2): ((2) wherein n represents an integer of 1-6). In this connection, R1-R3 are not hydrogen atoms at the same time).

Description

technical field This invention relates to a liquid crystal sealing compound and a liquid crystal display cell (cell) using the liquid crystal sealing compound. More specifically, the present invention relates to a liquid crystal sealant suitable for the manufacture of a liquid crystal display cell in which liquid crystal is dropped into The liquid crystal is sealed by bonding the other substrate to the inside of the bank of the photothermal curing combined use type and thermosetting liquid crystal sealing agent formed on one substrate, and curing the liquid crystal sealing agent. Background technique In recent years, along with the increase in size of liquid crystal display cells, a so-called liquid crystal drop processing method with higher mass productivity has been proposed as a method for manufacturing liquid crystal display cells (see Patent Document 1 and Patent Document 2). Specifically, this method is a method of manufacturing a liquid crystal display cell in which ...
