Abstract

본 발명은 액정표시소자에 관한 것으로, 특히 시야각이 넓은 액정표시소자에 관한 것이다. 본 발명에 따른 액정표시소자는 ; 복수의 표시화소전극들이 매트릭스 형태로 각각 배치되고, 서로 대향하는 한쌍의 기판 ; 상기 한쌍의 기판 사이에 배치된 액정층 , 및 적어도 일방의 기판의 상기 액정층에 대향하는 표면에 형성되고, 상기 액정층중의 액정분자의 배향상태를 제어하는 배향층 ; 을 구비하고 ; 상기 배향층은 본질적으로 폴리머 앨로이로 구성된다. 액정층중의 폴리머 앨로이가 상분리 구조를 갖기 때문에, 액정층중에 규칙적으로 형성된 부분을 얻을 수 있고, 이 부분의 액정분자들은 방사상, 이축성 또는 다축성으로 배향되며 이 부분의 크기를 제어할 수 있다. 그결과, 상하좌우 방향으로의 콘트라스트의 시각의존성에 의해 생길 수 있는 콘트라스트의 변화, 착색현상, 표시화상의 반전현상 등의 문제를 해소하여, 실질적으로 표시의 불균일이 거의 없는 높은 콘트라스트를 달성할 수 있다.
