KR950001355A - Manufacturing method of color filter - Google Patents

Abstract

The present invention relates to a manufacturing method of a color filter for a liquid crystal display, and in particular, the black matrix has a three-layer structure of a first black organic material, a metal, and a second black organic material, and blocks light reflected from the metal surface to prevent leakage of the thin film transistor. The present invention relates to a method for manufacturing a color filter for the purpose of preventing a color and improving the contrast of a color. The object of the present invention is to apply a first black organic material having a predetermined thickness on a transparent insulating substrate, and Forming a metal film by depositing a metal to a predetermined thickness on the first black organic material, applying a second black organic material on the metal film, and exposing, developing, and etching the second black organic material to pattern the second black organic material. Exposing, developing and etching the first black organic material to form a black matrix, and then sequentially on the transparent insulating substrate on the black matrix. By producing the pattern, and referred to the transparent conductive film forming step is achieved.
