Patent ID: 7092060

Claim:
A method for fabricating an array substrate for an in-plane switching liquid crystal display device, comprising: forming a gate line and a data line on a substrate, the gate line and the data line crossing each other to define a pixel region; forming a common line parallel to the gate line; forming a thin film transistor on the substrate, the thin film transistor being electrically connected to the gate and data lines; forming a plurality of common electrodes perpendicularly extended from the common line; forming a gate insulator over the plurality of common electrodes; forming a plurality of pixel electrodes on the gate insulator, wherein the plurality of pixel electrodes form an alternating pattern with the plurality of common electrodes; and forming an overcoat layer covering the plurality of common and pixel electrodes, the overcoat layer having a plurality of holes, wherein the plurality of holes expose a portion of the gate insulator.
