Abstract

본 발명은 주쇄가 요소결합 및 아미드결합에 의해 형성되는 특정한 중합체를 보유하는 것을 특징으로 하는 액정배향막에 관한 것이다.
본 발명의 액정배향막은 그 제조시 고온의 열처리를 필요로 하지 않으며, 150℃정도 이상의 온도에서 충분하므로, 제조가 용이하며 또 다른 소자재료를 손상할 우려가 없고, 기판으로서 글라스기판 뿐만아니라 내열성이 낮은 플라스틱 등도 사용할 수 있다. 그래서 그 액정배향막은 액정배향성, 내열성, 투명성, 강도, 기판과의 밀착성 등 여러 특성이 우수하며, 특히 높고 또한 안정성이 좋은 프리틸트각을 제공하므로, 본 발명의 액정표시소자는 특히 STN 방식의 액정표시소자에 매우 유리하게 사용할 수 있다.
