IN-PLANE SWITCHING LIQUID CRYSTAL DISPLAY DEVICE

An in-plane switching LCD(Liquid Crystal Display) device is provided to reduce the outer wire resistance by half by connecting the outer wire of each common electrode in a row with a conduction seal so as to improve the afterimage lag and picture quality. The first substrate(110) is formed by arranging the gate line and the data line vertically and horizontally. Multiple common electrode wires(115) are formed in mutually parallel to gate line on the first substrate. A first common electrode outer wire(119) is electrically connected to both ends of the common electrode wire, and is formed by one outer block having horizontality to the gate line and by both outer block having horizontality to the data line. A second substrate(230) is bonded for facing with the first substrate. A second common electrode outer wire(235) is electrically connected to the first common electrode outer wire so as to have mutual symmetry and correspondence on the second substrate. A contact part applies common voltage to at least one end of the first common electrode outer wire of the common electrode wire.
