Abstract

LCD용 칼라필터를 형성함에 있어서, 감광성 수지에 흑색안료를 용해하여 기판에 도포하고 포토리소그라피법으로 노광 에칭하여 블랙매트릭스를 형성하는 번거로운 공정상의 문제점을 해결하고자, 기판(1)의 상면에 통상의 포토리소그라피법으로 ITO전극(2)을 코오팅하고, 다시 그 위로 흑색안료를 스크린 인쇄하여 블랙매트릭스(3)를 형성 적층한 다음, 상기 ITO전극(2)의 상면으로 R, G, B필터층(4)을 도포하고, 오버코트(5)를 적층시킴에 따라 적어도 블랙매트릭스(3)를 간편하고 용이한 공정을 통해 형성시킬 수 있게 한 칼라 LCD의 블랙매트릭스 형성방법.In forming the color filter for LCD, in order to solve the troublesome process problem of dissolving black pigment in photosensitive resin, apply | coating to a board | substrate, and exposure-etching by the photolithographic method, and forming a black matrix, it is common on the upper surface of the substrate 1 The ITO electrode 2 is coated by photolithography, and the black pigment 3 is formed by screen printing black pigment thereon to form a black matrix 3, and then R, G, and B filter layers are formed on the upper surface of the ITO electrode 2 ( 4) A method of forming a black matrix of a color LCD which makes it possible to form at least the black matrix (3) through a simple and easy process by applying and laminating the overcoat (5).
