Patent ID: 8013970

Claim:
An array substrate for an in-plane switching mode liquid crystal display device, comprising: a gate line on a substrate; a data line crossing the gate line to define a pixel region; an auxiliary data line disposed over the data line and connected to the data line; a thin film transistor connected to the gate line and the data line; a first common line parallel to and spaced apart from the gate line; a plurality of pixel electrodes disposed in the pixel region and connected to the thin film transistor; and a plurality of common electrodes alternately arranged with the plurality of pixel electrodes in the pixel region and including first common electrodes disposed at a boundary area of the pixel region and at least one second common electrode between the first common electrodes, an end of the at least one second common electrode extending from the first common line, wherein the first common line, the second common electrode, the plurality of pixel electrodes and the auxiliary data line are formed of a same material and a same layer as one another and are disposed at a different level from the first common electrodes, and wherein a distance between the first common line and the auxiliary data line is greater than a distance between one of the first common electrode and the auxiliary data line.
