Patent ID: 7202928

Claim:
An array substrate for an in-plane switching liquid crystal display device, comprising: a gate line on a substrate; a data line crossing the gate line to define a pixel region having an aperture area; a thin film transistor disposed at one corner of the pixel region and connected to the gate line and the data line, the thin film transistor including a semiconductor layer; a common line spaced apart from the gate line and substantially parallel to the gate line; a common electrode extending from the common line and including a plurality of common electrode patterns, wherein an outermost portion of common electrode pattern is substantially rectangle-shaped within the pixel region and has a substantially circular opening in the middle thereof; a capacitor electrode overlapping the substantially rectangle shaped common electrode pattern, the capacitor electrode connected to the thin film transistor; a pixel connecting line disposed substantially parallel to the data line in the pixel region and connected to the capacitor electrode; and a pixel electrode disposed within the substantially circular opening, extending from the pixel connecting line and including a plurality of pixel electrode patterns, wherein an innermost pixel electrode pattern has a substantially circular shape and other pixel electrode are patterned to have circular bands, wherein an innermost portion of the plurality of common electrodes is circular band shaped, and wherein the aperture area is circular band shaped.
