PROBLEM TO BE SOLVED: To solve the problem in which: a conventional photo-alignment film has an insufficient long afterimage property.SOLUTION: A liquid crystal display device includes a substrate, a liquid crystal layer, an electrode group for applying an electric field to the liquid crystal layer, and an alignment control film arranged between the substrate and liquid crystal layer. The alignment control film is composed of polyimide and a precursor of polyimide, contains, as raw materials of polyimide and the precursor of polyimide, at least one of first diamines, at least one of second diamines, and a cyclobutane tetracarboxylic acid dianhydride derivative, and is provided with an alignment regulation power through the irradiation of substantially linearly polarized light. |
