Abstract: front page image
(EN)Provided is a method for controlling liquid crystal alignment. An alignment film has a plurality of first grooves which are elongated in a first direction and are spaced from each other, and a plurality of second grooves which are elongated in a second direction and are spaced from each other by crossing said first grooves. Multistable liquid crystal alignment or multi-domain liquid crystal alignment is enabled selectively by adjusting an aspect ratio of said first grooves and an aspect ratio of said second grooves.
(FR)L'invention concerne un procédé de commande de l'alignement de cristaux liquides. Un film d'alignement présente une pluralité de premières rainures qui sont allongées dans une première direction et sont espacées les unes des autres, ainsi qu'une pluralité de secondes rainures qui sont allongées dans une seconde direction et qui sont espacées les unes des autres par croisement desdites premières rainures. Un alignement des cristaux liquides multistable ou un alignement des cristaux liquides multi-domaine est activé sélectivement par le réglage d'un rapport d'aspect desdites premières rainures et un rapport d'aspect desdites secondes rainures.
(KO)액정 배향을 제어하는 방법이 제공된다. 배향막에 제1 방향으로 신장되고 서로 이격된 복수의 제1 홈과 제2 방향으로 신장하여 상기 제1 홈들과 교차하는 서로 이격된 복수의 제2 홈을 형성한다. 제1 홈의 종횡비 및 상기 제2 홈의 종횡비를 조절하여 다중안정 액정 배향 또는 다중 도메인 액정 배향을 선택적으로 가능하게 할 수 있다.
