Abstract

본 발명은 반사형 액정 표시 장치에 관한 것으로서, 본 발명에 의한 반사형 액정 표시 장치는 소스 전극 및 드레인 전극 위에 형성되고, TFT에서의 광 리크 전류를 억제하기 위한 차단층으로서 표면에는 전체적으로 요철 구조를 가지는 요철면이 형성된 폴리머층과, 상기 폴리머층상에 적충되고, 상기 폴리머층의 요철면의 요철 구조에 따라서 요철 구조로 형성된 반사판과, 상기 상찬과 상기 반사판 사이에 봉입된 액정층을 포함하여 구성된다. 본 발명에 의하면, 반사판에 요철면을 형성하는 공정을 단순화 할 수 있고, 리크 번류를 억제하기 위하여 하판에 형성되는 펼치리머층의 재료를 금속이 아닌 유기 고분자 화합물로 형성함응로써, 빛을 흡수하는 블랙 매트릭스로 작용하여 액정 표시 패널의 콘트라스트 비를 증가시켜 준다.The present invention relates to a reflective liquid crystal display device, wherein the reflective liquid crystal display device according to the present invention is formed on the source electrode and the drain electrode, and has a concave-convex structure on the surface as a blocking layer for suppressing the optical leakage current in the TFT. The branch includes a polymer layer having a concave-convex surface, a reflecting plate formed on the polymer layer, and having a concave-convex structure in accordance with the concave-convex structure of the concave-convex surface of the polymer layer, and a liquid crystal layer enclosed between the upper and lower reflecting plates. . According to the present invention, it is possible to simplify the process of forming the concave-convex surface on the reflecting plate, and to absorb light by forming the material of the spreading reamer layer formed on the lower plate with the organic polymer compound instead of the metal in order to suppress the leakage flow. It acts as a black matrix to increase the contrast ratio of the liquid crystal display panel.
