Abstract:
1. A method of fabricating an array substrate for a liquid crystal display device, the method comprising: forming a gate line in one direction on a surface of the substrate; forming a data line crossed with the gate line to define a pixel region; forming a thin-film transistor at an intersection of the gate line and data line; forming an organic insulating layer on an entire surface of the substrate including the thin-film transistor to have an opening portion for exposing the thin-film transistor; forming a common electrode having a large area at an upper portion of the organic insulating layer, and an auxiliary electrode pattern connected to the thin-film transistor through the opening portion; forming a passivation layer on an entire surface of the substrate including the common electrode and auxiliary electrode pattern to expose the auxiliary electrode pattern connected to the thin-film transistor; forming a plurality of pixel electrodes and electrically connected to the thin-film transistor through the exposed auxiliary electrode pattern, and overlapped with the common electrode at an upper portion of the passivation layer; and forming a common connection pattern for connecting a common line and the common electrode, respectively, at an upper portion of the passivation layer during the formation of the pixel electrode.
