    摘要： 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. An object of the invention is to efficiently produce and provide a display panel and a liquid crystal display device that have excellent electrical properties and optical properties, and have a sufficient liquid crystal display quality and reliability.

    摘要： A picture element includes a 4-divided domain including first, second, third and fourth sub-domains which are arranged in this order in a predetermined direction and in each of which an orientation direction of liquid crystal molecules located in the vicinity of the center of a liquid crystal layer in the thickness direction is different from those of the other sub-domains. A first substrate includes two first regions having an orientation-regulating force for orienting the liquid crystal molecules in a first direction and a second region provided between the two first regions and having an orientation-regulating force for orienting the liquid crystal molecules in a second direction that is opposite to the first direction. A second substrate includes a third region having an orientation-regulating force for orienting the liquid crystal molecules in a third direction that crosses the first direction and a fourth region having an orientation-regulating force for orienting the liquid crystal molecules in a fourth direction that is opposite to the third direction. The first sub-domain is formed between one of the two first regions and the third region, the second sub-domain is formed between the second region and the third region, the third sub-domain is formed between the second region and the fourth region, and the fourth sub-domain is formed between the other one of the two first regions and the fourth region.
