Abstract:
1. An array substrate for use in an in-plane switching liquid crystal display device, comprising: a plurality of gate lines disposed in a first direction on a substrate; a plurality of data lines disposed in a second direction perpendicular to the gate lines, wherein the gate and data lines have a straight line shape and pairs of the gate and data lines define a rectangular pixel regions; a circular common electrode disposed in each rectangular pixel region; a common line disposed to the first direction, the common line connecting the circular common electrode to the neighboring circular common electrode disposed in the neighboring rectangular pixel region; a circular pixel electrode disposed inside the circular common electrode with being spaced apart from the circular common electrode; a thin film transistor disposed near a crossing of the gate and data lines in the rectangular pixel region; and a pixel connecting line connecting the circular pixel electrode to the thin film transistor, wherein the thin film transistor is disposed at a corner of the pixel region and wherein the distance between the common line and two adjacent gate lines is substantially the same.
