Abstract

A method for manufacturing an array substrate is provided. The array substrate, by providing a black matrix and a color resist layer on the array substrate and providing the color resist layer on the TFT layer, prevents bad influences on the color resist layer caused by a high temperature TFT process so as to provide a liquid crystal panel with improved displaying quality. The method includes, firstly, forming a black matrix on a substrate, and secondly, implementing a TFT manufacture process on the black matrix, and then forming a color resist layer after the TFT manufacture process. Accordingly, forming both the black matrix and the color resist layer on the array substrate can be achieved, where the color resist layer is formed after the TFT manufacture process to prevent bad phenomenon caused by the high temperature of the TFT process.
