Patent ID: 7079213

Claim:
An array substrate for an in-plane switching mode liquid crystal display device, comprising: a substrate; a thin film transistor on the substrate; a gate line connected to the transistor; a data line crossing the gate line and connected to the transistor, the crossed data line and gate line defining boundaries of a pixel region; a pixel electrode disposed in the pixel region connected to the transistor, the pixel electrode including at least one vertical portion and a plurality of horizontal portions; and a common electrode disposed in the pixel region, the common electrode including at least two vertical portions and a plurality of horizontal portions, wherein the vertical portion of the pixel electrode is disposed between the vertical portions of the common electrode, and wherein the horizontal portions of the common electrode cross the vertical portion of the pixel electrode at a crossing region with a width of at least one of the horizontal portions of the common electrode at the crossing region being less than the width of the at least one of the horizontal portions of the common electrode at other regions, and a width of the vertical portion of the pixel electrode at the crossing region being less than the width of the vertical portion of the pixel electrode at other regions.
