Abstract

본 발명은 액정표시장치에 관한 것으로 블랙 매트릭스의 단차를 제거하고 이로 인해 공통전극의 저항을 개선하기 위한 것이다.
종래에는 투명기판에 단차를 갖는 블랙 매트릭스(2)를 형성하고 그 위에 칼라필터층(3), 오버코트층(4), 공통전극(5)을 형성하였다.
따라서 블랙 매트릭스의 단차가 발생하고, 블랙 매트릭스를 식각 공정에 의해 형성하므로 칼라필터층보다 먼저 형성해야 하는 공정에 제약을 받았다.
본 발명은 투명전극(1)위에 양극 산화 가능한 금속을 증착하고 화소 부분의 금속을 양극 산화하여 투명 절연체를 만들어 나머지 부분이 블랙 매트릭스가 된 것으로, 칼라 필터층을 먼저 형성하고 그 위에 블랙 매트릭스를 형성하며 오버코트층이 없어 바로 공통전극을 형성할수 있어 매트릭스 단차를 제거하고 공통 전극의 저항을 개선할수 있다.
