Abstract:
A fringe field switching liquid crystal display device comprising:an upper substrate; a lower substrate opposing the upper substrate; a data bus line arranged on the lower substrate intersecting a pair of substantially parallel storage capacitance bus lines arranged on the lower substrate to substantially define a unit pixel; a gate bus line arranged in the direction substantially parallel to the storage capacitance bus lines in between the storage capacitance bus lines, thereby substantially bisecting the unit pixel; a thin film transistor arranged on the gate bus line; a counter electrode formed in the unit pixel; and a pixel electrode overlapped with the counter electrode on the same substrate to form a fringe field and electrically contacted with the thin film transistor through a via hole; wherein the pixel electrode comprises a frame shaped body unit on the edge of counter electrode and a plurality of slant slits arranged with a regular distance to divide the body unit into several parts, forming a predetermined angle with the gate bus line, and the angle of slant slits in the pixel electrode is symmetric with respect to the gate bus line, and the storage capacitance bus line is partially overlapped with both the upper edge of pixel electrode in one unit pixel and the lower edge of pixel electrode in the closest unit pixel.
