Abstract:
A liquid crystal display device, comprising two substrates each having an alignment film, a sealing member arranged in the outer peripheries of said 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 said liquid crystal filling port into the clearance between the two substrates, and an end-sealing material for clogging the liquid crystal filling port,wherein total amounts of an alkyl acid represented by formula (1), phenyl carboxylic acid or a phenyl carboxylic acid derivative represented by formula (2), phenylene dicarboxylic acid or a phenylene dicarboxylic acid derivative represented by formula (3), an alkyl amine represented by formula (4), aniline or an aniline derivative represented by formula (5), phenylene diamine or a phenylene diamine derivative represented by formula (6), phenyleneamine carboxylic acid or a phenyleneamine carboxylic acid derivative represented by formula (7), an alkyl imide represented by formula (8), a phthalimide derivative represented by formula (9), a cyano benzene derivative represented by formula (10), and a dicyano benzene derivative represented by formula (11) contained in the sealing member, the end-sealing material and the spacer is not larger than 3%:R.sub.1.paren open-st.COOH).sub.n (1)##STR4##R.sub.1 --NH.sub.2 (4)##STR5##R.sub.1 --NR.sub.2 R.sub.3 (8)##STR6##where R.sub.1 is an alkyl group having 1 to 20 carbon atoms, R.sub.2 is --H or an alkyl group having 1 to 20 carbon atoms, R.sub.3 is an alkyl group having 1 to 20 carbon atoms, each of V, W, X, Y and Z is one selected from the group consisting of an alkyl group having 1 to 10 carbon atoms, an alkoxy group having 1 to 10 carbon atoms, --F, --Cl, --Br, --C.sub.6 H.sub.5 and --H, and n is 1 or 2.
