Abstract
(EN)
The structural composition of a desired polymer as a photo-alignment film, in which the constitutional unit has at least two side chains having a photo functional group, in a photo-alignment liquid crystal panel capable of achieving uniform display quality, highly reliable photo orientation, and excellent electrooptic properties (transmittance, contrast, viewing angle, and response), in order to improve the basic performance and high image quality of a liquid crystal display panel and a liquid crystal display, was unclear. The present invention was completed by containing a compound having photo orientation and optimizing the photo-polymer copolymerization ratio and the degeneration ratio so that the photo-alignment film has photo orientation and by finding the structural composition of the desired polymer as a photo-alignment film. The purpose of the present invention is to produce efficiently and provide a display panel and a liquid crystal display that have excellent electrical properties and optical properties, sufficient liquid crystal display quality, and reliability.

Afin d'améliorer les performances de base et la qualité d'image élevée d'un panneau d'affichage à cristaux liquides et d'un affichage à cristaux liquides, la composition structurelle d'un polymère voulu en qualité de film de photo-alignement, dans lequel l'unité constituante comprend au moins deux chaînes latérales ayant un groupe photo-fonctionnel, doit se trouver dans un panneau de cristaux liquides à photo-alignement capable d'offrir une qualité d'affichage uniforme, une photo-orientation de grande fiabilité et d'excellentes propriétés électro-optiques (transmittance, contraste, angle de vue et réponse). La présente invention a été réalisée en utilisant un composé ayant une photo-orientation et en optimisant le rapport de photopolymérisation et le rapport de dégénérescence de sorte que le film de photo-alignement possède une photo-orientation, et en découvrant la composition structurelle du polymère voulu en qualité de film de photo-alignement. Le but de la présente invention est de fabriquer efficacement et d'offrir un panneau d'affichage et un affichage à cristaux liquides qui possèdent d'excellentes propriétés optiques et électriques, ainsi qu'une qualité d'affichage à cristaux liquides suffisante et une bonne fiabilité.
