Abstract
The present invention provides a liquid crystal display device in which even in the case of using a photo-alignment technique, excellent afterimage characteristics can be stably obtained.Provided is a liquid crystal display device including a TFT substrate having an alignment film, an opposed substrate which is arranged to face the TFT substrate and on which an alignment film is formed, and a liquid crystal layer sandwiched between the alignment films, wherein the alignment films are materials that can provide a liquid crystal alignment restraining force by irradiating polarized light, and the ratio of oxygen atoms on the surface of the alignment film is higher than that in the alignment film.
