Triazine based polymeric composite material for photoinduced liquid crystal alignment the method of making liquid crystal alignment layer comprising the same and a liquid crystal device

摘要

PURPOSE: A photosensitive polymer liquid crystal orientation compound containing a triazine ring as a main chain, a manufacturing method of liquid crystal orientation film and a liquid crystal display are provided to improve the definition and the quality of the liquid crystal display by manufacturing the liquid crystal display of the photosensitive polymer liquid crystal orientation compound. CONSTITUTION: A liquid crystal orientation material is composed of a triazine ring including one or more photoactive groups as a main chain, and dissolved in an organic solvent with density of 1-20 wt% and viscosity of 1-100 cps. A light orientation film(20) of 10-500nm is formed by spreading the liquid crystal orientation composition on a substrate(22) with spin-coating or printing. Ultraviolet rays(24) polarized linearly by a polarizer or unpolarized ultraviolet rays(24a) are irradiated to the surface of the light orientation film vertically or with being inclined. The image quality is improved by manufacturing the liquid crystal display with the liquid crystal orientation material including the triazine ring.
