Abstract:
A liquid crystal display device includes: a pair of substrates, at least one of which is transparent; a liquid crystal layer placed between the pair of substrates; an electrode group, formed on at least one of the pair of substrates, for applying an electric field to the liquid crystal layer; and an alignment control film placed on at least one of the pair of substrates, in which the alignment control film is formed of polyimide and a precursor of the polyimide, each of the polyimide and the precursor of the polyimide contains, as a material, a specific cyclobutanetetracarboxylic acid dianhydride derivative and aromatic diamine, and the alignment control film is provided with alignment capability by photo-alignment treatment.
