Abstract

아모포스 트위스트네마틱 액정셀은 폴리실록산물질이 성막된 기판(10),(11)을 합착하여 액정셀을 형성하며, 이 액정셀에 상온에서 액정을 주입하고 네마틱전이 온도(TNI) 이상으로 가열한 후, 상온으로 천천히 냉각시킴으로써 제작한다. 액정셀이 냉각됨에 따라 셀내에는 많은 도메인들이 형성되는데, 이 도메인들은 인접하는 도메인과 연속적으로 분포되며, 각 도메인내의 액정방향자도 같은 도메인내에 형성된 상하의 인접하는 도메인과 미세한 각도차를 갖는 연속적인 분포가 된다. 인접하는 도메인 사이의 액정분자의 배향을 연속적으로 분포시키기 위해, 액정의 주입전이나 주입후에 액정셀에 자외선을 조사하여 적당한 크기와 방향의 프리틸트를 부여한다.Amorphous twisted nematic liquid crystal cell with polysiloxane material is a film-forming substrate 10, to form a liquid crystal cell by cementation (11), the injection of the liquid crystal at room temperature, to the liquid crystal cell and the nematic transition temperature (T NI) above After heating, it is slowly cooled to room temperature. As the liquid crystal cell is cooled, a large number of domains are formed in the cell. These domains are continuously distributed with the adjacent domains, and the liquid crystal director in each domain has a continuous distribution having fine angular difference from the upper and lower adjacent domains formed in the same domain . In order to continuously distribute the orientation of the liquid crystal molecules between the adjacent domains, ultraviolet rays are irradiated to the liquid crystal cell before and after the injection of the liquid crystal to give a pretilt of an appropriate size and direction.
