Abstract: A method of manufacturing an array substrate includes applying a first color filter and a second color filter over a first and second pixel regions respectively and the color filters have an overlapped portion in wiring region; and forming a contact hole, which partially exposes the drain electrode therethrough, by etching at least one of the overlapping first and the second color filters, and the forming the contact hole includes selectively etching an upper part of the overlapped portion during etching a photoresist layer covering the overlapped portion, the overlapped portion of first and second color filters is etched without requiring an additional masking process, preventing a decrease of liquid crystal margin due to large height difference of the overlapped color filters, preventing misalignment of color filters and mixing of colors.
