Patent ID: 7916258

Claim:
An in-plane switching liquid crystal display device comprising: a gate line formed of a first material on a first substrate; a data line on the first substrate, the data line being perpendicular to the gate line; a common line on the first substrate, the common line being parallel with the gate line and being formed of a metal; a plurality of pixel electrodes and a plurality of common electrodes having finger portions and arranged in parallel on the first substrate, the common electrodes being a transparent conductive second material different from the first material, and the pixel electrodes being one of a transparent and opaque material; a first connecting line parallel to the gate line, wherein the plurality of pixel electrodes are perpendicular to the first connecting line, first ends of the pixel electrodes are connected to the first connecting line and second ends of the pixel electrodes are connected to a second connecting line; an auxiliary common line connected with the plurality of common electrodes, the auxiliary common line covering the common line such that the auxiliary common line contacts side and top surfaces of the common line; a storage electrode over the common line, wherein the storage electrode contacts the second connecting line via a storage contact hole; and a liquid crystal layer between the first and second substrates, wherein the common electrodes alternate with and are parallel to the pixel electrodes, wherein the common electrodes are formed on a same layer of the first substrate as the gate line.
