Abstract: A method of manufacturing a photo-alignment layer, includes: disposing a polymer material on a substrate; pre-baking the polymer material disposed on the substrate; irradiating a light to the pre-baked polymer material, to photo-align the pre-baked polymer material; and thermal-treating the irradiated pre-baked polymer material, to harden the irradiated pre-baked polymer material. The thermal-treating includes a first thermal-treatment, and a second thermal-treatment at a higher temperature than the first thermal-treatment.

Abstract: 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%.
