A Study on Electro-optical Characteristics of the Photoaligned VA-LCD on the Polynobornene Derivative Surface

Polynobornene 유도체 표면을 이용한 광배향 VA-LCD의 전기광학특성에 관한 연구

  • Published : 2002.03.01

Abstract

A new photoalignment material PNC, pole norbornene-2,3-dicarboxyolyl cholesterol, was synthesized and the electro-optical (EO) characteristics of the vortical-alignment (VA) liquid crystal display (LCD) photoaligned with UV exposure on the PNC surface were studied. EO characteristics of the photoaligned VA-LCD using a UV filter-less method was better than that of the UV filter method on the PNC surface for short UV exposure time. The response time of the photoaligned VA-LCD on the PNC surface without UV filter on the PNC surface is almost the same compared with the rubbing aligned VA-LCD.
