Abstract: In a photo-alignment liquid crystal panel capable of achieving a uniform display quality and highly reliable photo-alignment properties, and excellent electro-optical properties (transmittance, contrast, viewing angle, and response) for improving a basic performance and a high image quality of a liquid crystal panel and a liquid crystal display device, a structural composition of a polymer, which is preferable as a photo-alignment film, is unclear. The invention optimizes a copolymerization ratio and a modification rate of a photopolymer in order for a compound having photo-alignment properties to be contained as the photo-alignment film so as to enable the photo-alignment film to have the photo-alignment properties, and achieves the discovery of a preferred structural composition of the polymer.
