Title: (KO) 광배향 처리법용의 액정 배향제, 및 그것을 사용한 액정 배향막
Abstract:
(KO) IPS 구동 방식이나 FFS 구동 방식의 액정 표시 소자에 있어서 발생하는 교류 구동에 의한 잔상을 억제할 수 있는, 광배향 처리법용에 적합한 액정 배향제, 및 그 액정 배향제로부터 얻어지는 액정 배향막을 제공한다. 시클로부탄 골격을 갖는 특정 구조의 테트라카르복실산 2 무수물과 p-페닐렌디아민으로 대표되는 직선성이 높은 디아민 화합물을 갖는 디아민 화합물과의 중축합 반응으로부터 얻어지는 폴리아믹산 ((A) 성분) 과, 탄소수 3 ∼ 10 의 알킬기, 또는 알케닐기를 갖는 이미다졸 유도체 ((B) 성분) 와, 유기 용제를 함유하는 광배향 처리법용의 액정 배향제.
