| titleOfInvention | Liquid-crystal alignment material, liquid-crystal alignment film, and liquid-crystal display element |
| abstract | Provided is a liquid-crystal alignment material capable of giving a liquid-crystal alignment film which has a high voltage retention and which, even after having been exposed to a high-temperature atmosphere over long, is reduced in residual charge accumulated by direct-current voltage. Also provided is a liquid-crystal display element employing the liquid-crystal alignment film. The liquid-crystal alignment material comprises a copolymer obtained by reacting a diamine ingredient comprising at least one diamine compound (A) and a diamine compound (B) with a tetracarboxylic dianhydride. Diamine compound (A): at least one compound selected from the group consisting of compounds of the formulae [T1], [T2], and [T3], which are diamine compounds having a tertiary nitrogen atom. Diamine compound (B): a diamine compound having a carboxy group in the molecule. (Chemical formula 1) [T1] [T2] [T3] (In the formulae [T1] to [T3], W1 is a benzene ring or nitrogenous aromatic heterocycle; W2 is an aromatic group having 6 to 15 carbon atoms and having one or two benzene rings; W3 is C2-5 alkylene or biphenylene; W4 is cycloalkylene having 4 to 6 carbon atoms and substituted by a tertiary nitrogen atom; W5 is C2-5 alkylene; Z1 is amino substituted by two C1-6 aliphatic groups when W1 is a benzene ring, or Z1 is hydrogen or amino substituted by two C1-6 aliphatic groups when W1 is a nitrogenous aromatic heterocycle; Z2 is C1-5 alkyl or a benzene ring; and g is an integer of 0 or 1.) |
