Abstract:
1. A method of forming an array substrate for use in a liquid crystal display device, comprising: forming a gate line on a substrate along a first direction, a gate pad at one end of the gate line, and a gate electrode extending from the gate line; forming a first gate insulating layer on the substrate to cover the gate line, the gate pad, and the gate electrode; forming an active layer of intrinsic amorphous silicon and an ohmic contact layer of extrinsic amorphous silicon layer sequentially on the first gate insulating layer over the gate electrode; forming a data line, a data pad, a source electrode, and a drain electrode, the data line disposed extending along a second direction to perpendicularly cross the gate line to define a pixel region, the data pad disposed at one end of the data line, the source electrode extending from the data line on a first portion of the ohmic contact layer, and the drain electrode spaced apart from the source electrode on a second portion of the ohmic contact layer to form a thin film transistor; forming a second insulating layer over an entire surface of the substrate to cover the thin film transistor; forming a black matrix on the second insulating layer to cover the thin film transistor, the gate line, and the data line except a first portion of the drain electrode; forming a third insulating layer over an entire surface of the substrate to cover the black matrix; patterning the first, second, and third insulating layers to expose the first portion of drain electrode, to form a gate pad contact hole exposing the gate pad, and to form a data pad contact hole exposing the data pad; forming a first transparent electrode layer over an entire surface of the substrate to cover the patterned third insulating layer and contacting the exposed first portion of the drain electrode; coating an adhesive color film on the first transparent electrode layer, the adhesive color film having a color resin on a surface facing the first transparent electrode layer; irradiating a laser to portions of the adhesive color film corresponding to the pixel region; removing the adhesive color film after irradiating the laser to form a color film within the pixel region wherein the laser is irradiated; repeating coating the adhesive color film, irradiating the laser and removing the adhesive color film to form the color film within all of the pixel regions; forming a second transparent electrode layer over an entire surface of the substrate to cover the color filter and the first transparent electrode layer; and patterning the first and second transparent electrode layers to form first and second pixel electrodes, a double-layered gate pad terminal, and a double-layered data pad terminal.
