Liquid crystal sealant and liquid crystal display unit using same

Abstract

Provided is a liquid crystal sealing agent for liquid crystal dropping methods, which exhibits excellent application workability, low water vapor permeability and low water absorption, while having high Tg. A liquid crystal sealing agent for liquid crystal dropping methods, which contains (A) a compound represented by general formula (1-1) and (B) a radical polymerization initiator and / or (C) a thermal curing agent. In formula (1-a), each of X1 and X2 independently represents a group represented by one of general formulae (1-a) to (1-c), wherein R1 represents a hydrogen atom or a hydrocarbon group having 1-4 carbon atoms, R2 represents a hydrocarbon group having 1-5 carbon atoms, R3 represents a hydroxyl group or a substituent obtained by reacting a hydroxyl group with an acid anhydride, and each of p and q represents an average repetition number that is a number of 0-6.

Description

technical field

[0001] The present invention relates to a liquid crystal sealing compound used in a liquid crystal dropping method and a liquid crystal display unit using the liquid crystal sealing compound. More specifically, the present invention relates to a liquid crystal sealing agent used in a liquid crystal dropping method, which can manufacture highly reliable liquid crystal display units because of its excellent coating workability, especially its excellent water vapor permeability and water absorption rate. . Background technique

[0002] With the increase in size of liquid crystal display units in recent years, a so-called liquid crystal dropping method with higher mass productivity has been proposed as a method for manufacturing liquid crystal display units (Patent Document 1, Patent Document 2). Specifically, this method is a method of manufacturing a liquid crystal display unit in which liquid crystal is dropped on the inner side of a bank formed by a liquid c...
