A synthesis of new photoalignment material PNC, poly norbornene-2,3- dicarboxylic acid cholesteryl ester, and the electro-optical (EO) performances of the photoaligned vertical-alignment (VA)-liguid crystal display (LCD) on the PNC surface were studied. EO characteristics of the photoaligned VA-LCD on the PNC layer using a UV filter-less method proved more effective that of the UV filter method for short UV exposure time. The response time of the photo-aligned VA-LCD on the PNC layer by the photoalignment method without UV filter is almost the same as the rubbing aligned VA cell.
