Patent ID: 7088328

Claim:
A liquid crystal display device, comprising: a plurality of pixel transistors respectively connected to corresponding signal lines and corresponding scanning lines at intersection portions of a plurality of the signal lines and a plurality of the scanning lines; pixel electrodes respectively connected to corresponding pixel transistors at the intersection portions; a signal line driving IC configured to output video signals whose polarities are inverted in a prescribed cycle to a plurality of respective output terminals; and a signal line switching circuit configured to be connected to the output terminals and output the video signals to the pixel electrodes via the signal lines so that the polarities of video signals supplied to pixel electrodes adjacent to an arbitrary pixel electrode on both sides thereof in a horizontal scanning direction are different from each other and the polarities of video signals supplied to pixel electrodes adjacent to the arbitrary pixel electrode on both sides thereof in a vertical scanning direction are different from each other, said signal line switching circuit configured to select the signal lines according to the same timing as the prescribed cycle and supply the video signals to the selected signal lines.
