Abstract: 본 발명은 고분자 액정복합막을 이용하는 고분자분산 반사정 액정표시소자에 관한것으로, 반사형 표시장치에서는 투과율이 높은특성보다 기본적인 대비에 의한 콘트라스트가 중요하므로 하부기판 내면에 비표시부위의 기본투과율을 저하시켜 콘트라스트를 향상시키는 오버레이 그래픽수단을 부가한 것으로, 오버레이 그래픽 수단은 필름 스페이서에 표시부위만 고분자 액정층을 도포시켜 구현하거나, 도전성 하부 또는 상부기판의 비표시부 해당부위를 열처리하여 투과율을 낮춘구조로 구현 가능한 것이며, 별도의 오버레이 그래픽층이 필요없어 제조공정이 간단해지고 콘트라스트 향상 및 공정을 간소화시킨다.
