Abstract:
(EN) The present invention relates to a cleaning agent composition for liquid crystal alignment films, a method for preparing a liquid crystal alignment film, using the same, and a liquid display device comprising a liquid crystal alignment film prepared by the method. More particularly, provided are a cleaning agent composition for liquid crystal alignment films, which comprises a specific solvent and is used in a cleaning process after a UV alignment process to solve the problem of non-uniformity in liquid crystal alignment films and to effectively remove ionic byproducts on the polymer surface, with the consequent improvement of anisotropy in the liquid crystal alignment films, and a method for preparing a liquid crystal alignment film.
(FR) La présente invention concerne une composition d'agent de nettoyage pour films d'alignement de cristaux liquides, un procédé de préparation d'un film d'alignement de cristaux liquides l'utilisant, et un dispositif d'affichage à cristaux liquides comprenant un film d'alignement de cristaux liquides préparé par le procédé. Plus particulièrement, l'invention concerne une composition d'agent de nettoyage pour films d'alignement de cristaux liquides, qui comprend un solvant spécifique et est utilisée dans un processus de nettoyage après un processus d'alignement par UV pour résoudre le problème de non uniformité dans des films d'alignement de cristaux liquides et pour éliminer efficacement des sous-produits ioniques sur la surface du polymère, avec l'amélioration conséquente de l'anisotropie dans les films d'alignement des cristaux liquides, et un procédé pour préparer un film d'alignement de cristaux liquides.
(KO) 본 발명은 액정 배향막용 세정제 조성물과 이를 이용한 액정 배향막의 제조방법 및 상기 방법으로 제조된 액정 배향막을 포함하는 액정표시소자에 관한 것이다. 보다 구체적으로, UV 배향 공정 후 세정 공정에서 특정 용매를 포함한 세정제 조성물을 사용함으로써 액정 배향막의 불균일 문제를 해결하고 고분자 표면의 이온성 부산물을 효과적으로 제거하여 액정 배향막의 이방성을 높일 수 있는 액정배향막용 세정제 조성물과 액정 배향막의 제조방법이 제공된다.
