Abstract: PROBLEM TO BE SOLVED: To provide an array substrate for liquid crystal display device and a fabricating method of the same, capable of improving the process yield by reducing a manufacturing cost and time through further simplification of mask processes. SOLUTION: The array substrate for liquid crystal display device is manufactured by using a mask having half transmitting portions of slit widths different from each other upon the second process. Thereby, on the ashing process of a photosensitive layer, etching ratio on a part where wiring is positioned is equalized to the etching ratio on a part where the wiring is not positioned and, therefore, the advantage of preventing a defect from occurring on the surface of the wiring can be obtained. This invention is also characterized in that the array substrate is manufactured through three mask processes. COPYRIGHT: (C)2007,JPO&INPIT
