Abstract:
1. An array substrate for use in 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 electrode disposed in the pixel region and having first and second common electrode patterns, wherein the first common electrode pattern is substantially rectangle-shaped and has a substantially circular opening in the middle thereof, and the second common electrode pattern is disposed in the substantially circular opening and has a substantially gyre shape; a common line substantially perpendicular to and crossing the data line and connecting the common electrode to a neighboring common electrode in a neighboring pixel region; a capacitor electrode overlapping the first common electrode pattern, the capacitor electrode connected to the thin film transistor; and a pixel electrode disposed within the substantially circular opening and having a substantially gyre shape along a side of the second common electrode pattern, wherein the pixel electrode and the second common electrode pattern each have the substantially gyre shape, wherein the aperture area is substantially gyre shaped.
