Patent ID: 7580022

Claim:
A method of driving a in-plane switching mode liquid crystal display device, comprising: providing the liquid crystal display device, the liquid crystal display device including: a plurality of gate lines and data lines defining a plurality of pixel regions, each of the pixel regions being divided into first and second regions; a thin film transistor at each of pixel regions; a plurality of pixel electrodes in the pixel regions; and a plurality of common electrodes parallel to the pixel electrode in each of the pixel regions to generate horizontal electric field, forming different horizontal electric fields in the first region and the second region of the pixel region, wherein thin film transistor includes a gate electrode integrally formed with the gate line on a first substrate, a gate insulating layer on the gate electrode, a semiconductor layer on the gate insulating layer, a source electrode on the semiconductor layer, and a drain electrode facing with the source electrode on the semiconductor layer and being extended to the adjacent two pixel regions to supply the data signal to the adjacent two pixel region; and a passivation layer.
