Abstract
A liquid crystal display device suppresses generation of image sticking in AC mode. A liquid crystal display device comprises an alignment film arranged on at least one of a pair of substrates. The alignment film comprises a polymer containing a first constitutional unit and a second constitutional unit. The first constitutional unit controls alignment of the liquid crystal molecules by photoirradiation. The second constitutional unit controls alignment of the liquid crystal molecules regardless of photoirradiation.
