The purpose of the present invention is to provide a photo-alignment film polymer which can form a photo-alignment film having excellent alignment regulating force, a photo-alignment film formed from said photo-alignment film polymer, and an optically anisotropic body and a liquid crystal display element having the photo-alignment film. This photo-alignment film polymer enables forming a photo-alignment film having excellent alignment regulating force. Because the photo-alignment film has excellent liquid crystal alignment properties, it is possible to reduce AC burn-in of a liquid crystal display element that has said photo-alignment film.
