Patent ID: 7259821

Claim:
An in-plane switching liquid crystal display device comprising: a first substrate and a second substrate; a gate line and a common line on the first substrate; a first insulating layer over the gate line; a data line on the first insulating layer and perpendicular to the gate line; a thin film transistor at a crossing point of the gate and data lines; the thin film transistor including a source electrode, a drain electrode and a gate electrode; a second insulating layer of an organic material over the first substrate; transparent pixel electrodes on the second insulating layer; transparent common electrodes on the second insulating layer, wherein the common electrodes and the pixel electrodes form an alternating pattern, the common electrodes including an outermost common electrode adjacent to the data line; a capacitor electrode overlapping the common line and connected to the pixel electrodes via a contact hole, wherein the capacitor electrode and common line form a storage capacitor having the first insulating layer therebetween; an auxiliary pixel electrode on the second insulating layer and connected to the drain electrode through a contact hole in the second insulating layer; an auxiliary common electrode on the second insulating layer, wherein the auxiliary common electrode electrically contacts respective first ends of the common electrodes and electrically contacts the common line via a contact hole through the first and second insulating layers; and a liquid crystal layer between the first and second substrates, wherein the outermost common electrode and the data line are on different layers and wherein a portion of the outermost common electrode overlaps the data line.
