PURPOSE: A liquid crystal display using polynobornene derivative surface is provided to realize a wide viewing angle in the multi-domain method by using UV radiation technique and realize the high speed response time and the high contrast ratio by using VA-LCD optically-orientated by polarizer UV radiation for a PNC(poly norbornene-2,3-dicarboxyolyl cholesterol) surface as a homeotropic material. CONSTITUTION: In a liquid crystal display using polynobornene derivative surface, PNC monomer is synthesized by melting chloroform in cholesterol and triethylamine, mixing trans-5-Norbornene-2,3-dicarbonylchloride to chloroform, stirring the mixture at a room temperature for four hours, and evaporating solvent of a separated organic layer. The PNC substrate is formed with four domains by forming each photo mask for first to fourth domains and carrying out UV-radiation thereon repeatedly, wherein opened parts not covered by the each photo mask are optically oriented. |
