LIQUID CRYSTAL-ALIGNING AGENT, LIQUID CRYSTAL ALIGNMENT LAYER, LIQUID CRYSTAL DISPLAY ELEMENT, POLYMER AND COMPOUND

摘要

PROBLEM TO BE SOLVED: To improve weather-resistance of a liquid crystal-aligning layer.SOLUTION: A liquid crystal-aligning agent contains at least one kind of polymer selected from a group consisting of polyamic acids obtained by reacting tetracarboxylic acid dianhydride and diamine containing a compound (a) expressed by the formula (A), and polyimide prepared by dehydrating and ring-closing the polyamic acids.
