Patent ID: 8284365

Claim:
A method of driving a liquid crystal display device including first and second substrates facing each other, a liquid crystal layer between the first and second substrates, a plurality of first pixel electrodes in corresponding first sub-pixel regions of an inner surface of the first substrate, a plurality of first common electrodes on the inner surface of the first substrate, the plurality of first common electrodes alternating with the plurality of first pixel electrodes, a second pixel electrode in a second sub-pixel region of inner surface of the first substrate, and a second common electrode on an inner surface of the second substrate, the second common electrode facing the second pixel electrode, wherein the second sub-pixel region is centrally located with respect to the plurality of first sub-pixel regions, the method comprising: applying a first common voltage to the plurality of first common electrodes to generate a substantially horizontal electric field between the plurality of first pixel electrodes and the plurality of first common electrodes in the corresponding first sub-pixel regions; and applying a second common voltage to the second common electrode to generate a substantially vertical electric field between the second pixel electrode and the second common electrode in the second sub-pixel region.
