Abstract

균일한 크기의 액정 도메인, 그 형성방법 및 중합체 분산 액정 디스플레이에서의 그 효능이 개시된다.
본 발명의 방법은 중합체로 둘러싼 액정 (Polymer Encased Liquid Crystal, PELC)으로 알려진, 중합체 쉘로 둘러싸여진 액정 불연속 도메인을 형성할 수 있게 한다. 나아가, 이 방법은 균일한 크기의 입자를 갖는 PELC를 제조할 수 있게 한다. 균일한 크기의 PELC를 포함하여 만들어지 표시장치는 통상의 중합체 분산 액정공정으로 제조된 표시장치보다 전자-광학적 성능이 크게 개선됨을 보여준다.
