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： The present invention provides a liquid crystal display device that has good reliability and can inhibit an image sticking phenomenon even when a comparatively low temperature is set for baking the alignment layer, and a method for manufacturing such a liquid crystal display device. The liquid crystal display device of the prevent invention includes a configuration in which a liquid crystal layer including liquid crystal molecules is sandwiched between a pair of substrates, and includes an alignment layer on a surface of at least one of the substrates on the liquid crystal layer side thereof. The alignment layer is obtained by performing an aligning treatment by light irradiation on a layer formed using an alignment layer material including a first constituent material and a second constituent material. The first constituent material demonstrates a property of controlling the alignment of the liquid crystal molecules under light irradiation. The second constituent material is a polymer which has no property of controlling the alignment of the liquid crystal molecules, and at least part of which is imidized.
