摘要： Provided is a liquid crystal display that 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 of 10% to 30%.
