    摘要： A liquid crystal display device includes a display medium containing at least liquid crystal between a pair of substrates at least one of which is transparent. At least one of the pair of substrates is provided with a film having a concave portion on the side of the display medium. The concave portion has a bottom portion in a vicinity of a center when viewed from a normal direction of the substrate. Liquid crystal molecules contained in the display medium are oriented axisymmetrically around the bottom portion or the vicinity thereof. The contour defining the concave portion in a vertical plane bisecting the bottom portion is a curve and the sign of a second differential of the curve is positive or negative or partially positive and partially negative or the gradient of a surface of the film having the concave portion continuously changes at a border between a pixel portion where the liquid crystal region lies and a non-pixel portion.

    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.
