고내열성 광폴리머 표면을 이용한 광배향 TN 셀의 전기광학 특성의 연구
Study of Electro-Optical Characteristics on Photoalignment TN Cell using a High Thermal Photopolymer
초록
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
