Abstract
Disclosed is a liquid crystal display device, comprising two substrates each having an alignment film, a sealing member arranged in the outer peripheries of the two substrates to permit the outer peripheries of these two substrates, which are arranged such that the alignment films of these two substrates face each other, to be bonded to each other except a liquid crystal filling port, a spacer for keeping the two substrates a predetermined distance apart from each other, a liquid crystal layer formed by filling a liquid crystal material through the liquid crystal filling port into the clearance between the two substrates, and an end-sealing material for sealing the liquid crystal filling port, wherein total amounts of an alkyl acid, phenyl carboxylic acid or a phenyl carboxylic acid derivative, phenylene dicarboxylic acid or a phenylene dicarboxylic acid derivative, an alkyl amine, aniline or an aniline derivative, phenylene diamine or a phenylene diamine derivative, phenyleneamine carboxylic acid or a phenyleneamine carboxylic acid derivative, an alkyl imide, a phthalimide derivative, a cyano benzene derivative, and a dicyano benzene derivative contained in the sealing member, the…
