Study of Electro-Optical Characteristics on Photoalignment TN Cell using a High Thermal Photopolymer
고내열성 광폴리머 표면을 이용한 광배향 TN 셀의 전기광학 특성의 연구
Abstract
We synthesized photoalignment material of high thermal resistance with hydroxyl aromatic polyimide, and studied the liquid crystal (LC) aligning capabilities on the photopolymer layers. Also, electro-optical (EO) performances for the twisted-nematic (TN)-liquid crystal display (LCD) photoaligned with linearly polarized UV exposure were investigated. A good LC alignment with UV exposure on the photopolymer surface can be obtained. However, the low pretilt angles were obtained below
