| titleOfInvention | Liquid-crystal alignment material and liquid-crystal display element made with the same |
| abstract | Provided is a liquid-crystal alignment material giving a liquid-crystal alignment film which has a high voltage retention and which, even after long-term exposure to a high temperature, retains the property of quickly diminishing a residual charge accumulated by a direct-current voltage. Also provided is a liquid-crystal display element having the liquid-crystal alignment film. The liquid-crystal alignment material comprises a copolymer obtained by reacting a diamine ingredient comprising a diamine compound (A) and a diamine compound (B) with a tetracarboxylic dianhydride. Diamine compound (A): a diamine compound represented by the following formula [1] Diamine compound (B): a diamine compound having a carboxy group in the molecule (Chemical formula 1) [1] (In the formula [1], X1 is at least one divalent organic group selected from the group consisting of -O-, -NQ1-, -CONQ1-, -NQ1CO-, -CH2O-, and -OCO-; Q1 is hydrogen or C1-3 alkyl; X2 is a single bond or at least one divalent organic group selected from the group consisting of C1-20 aliphatic hydrocarbon groups, nonaromatic cyclic hydrocarbon groups, and aromatic hydrocarbon groups; X3 is a single bond or at least one divalent organic group selected from the group consisting of -O-, -NQ2-, -CONQ2-, -NQ2CO-, -COO-, -OCO-, and -O(CH2)m- (m is an integer of 1-5); Q2 is hydrogen or C1-3 alkyl; X4 is a nitrogenous aromatic heterocycle; and n is an integer of 1-4.) |
