Abstract

칼라 패턴의 표면이 평탄하고 광 밀도가 높은 액정 표시 장치의 칼라 필터 및 그 제조 방법에 관하여 개시한다. 본 발명은 기판 상에 일정주기로 형성된 복수의 블랙 매트릭스들과, 상기 블랙 매트릭스들 사이에 마련되고, 상기 블랙 매트릭스의 높이와 동일한 높이의 복수의 칼라필터 패턴들과, 상기 블랙 매트릭스들 및 칼라필터 패턴들 상에 형성되는 공통전극을 구비하는 것을 특징으로 하는 액정 표시 장치의 칼라 필터를 제공한다. 상기 공통전극은 ITO(Indium Tin Oxide)로 구성한다. 본 발명에 의하여 형성된 액정표시장치의 칼라패턴들은 블랙 매트릭스에 오버랩되어 형성되지 않기 때문에 보호막을 형성하지 않아도 된다. 또한, 블랙 매트릭스와 동일두께로 칼라 패턴들을 형성하여 높은 콘트라스트를 갖는 액정표시장치를 제조할 수 있다.The color filter of the liquid crystal display device with a flat surface of a color pattern, and high light density, and its manufacturing method are disclosed. The present invention provides a plurality of black matrices formed at regular intervals on a substrate, a plurality of color filter patterns provided between the black matrices, and having the same height as the height of the black matrix, the black matrices and the color filter pattern. It provides a color filter of the liquid crystal display device comprising a common electrode formed on the field. The common electrode is made of indium tin oxide (ITO). The color patterns of the liquid crystal display device formed by the present invention do not need to form a protective film because they are not overlapped with the black matrix. In addition, it is possible to manufacture a liquid crystal display device having high contrast by forming color patterns with the same thickness as the black matrix.

Description
