LIQUID CRYSTAL DISPLAY

摘要

PROBLEM TO BE SOLVED: To provide a liquid crystal display having a photodecompositional photoalignment layer with an improved anisotropy and an optimum decomposition efficiency.SOLUTION: A liquid crystal display includes: a first substrate; a thin film transistor disposed on the first substrate; a first electrode connected to the thin film transistor; and a first alignment layer disposed on the first electrode. The first alignment layer is formed by polymerizing a diamine and at least one of cyclobutane dianhydride (CBDA) and a cyclobutane dianhydride (CBDA) derivative. A decomposition efficiency representing a change in imidization ratio included before and after light exposure of the first alignment layer is in a range from 10% to 30% inclusive.
