Abstract

본 발명은 액정셀의 배향막 물질인 전폴리머(Prepolymer)를 폴리오로 신나 메이트(Polyiminde fluoro cinnamate)로 함으로써 열안정성이 뛰어나고 러빙(Rubbing)하지 않으면서 액정을 원하는 방향으로 배향할수 있는 광고분자 물질과 이를 이용한 배향막에 관한 것으로, 폴리이미드계 폴리머에 플루오로 신남산(fluoro cinnamic acid)이 치환된 폴리이미드 플루오로 신나메이트(Polyimide fluoro cinnamate)에 선편광된 UV 빛을 조사하여서 된 광고분자 물질과 이를 이용한 배향막에 관한 기술임.According to the present invention, the prepolymer, which is the alignment layer material of the liquid crystal cell, is made of polyiminde fluoro cinnamate. The alignment film used is an advertisement molecule material obtained by irradiating linearly polarized UV light on a polyimide fluoro cinnamate substituted with fluoro cinnamic acid to a polyimide polymer and an alignment film using the same. Description of the technology.
