Abstract
A signal line driving circuit makes the polarities of video signals different from each other, the video signal being supplied to pixel electrodes adjacent to an arbitrary pixel electrode on both sides thereof in a horizontal scanning direction. The signal line driving circuit also makes the polarities of video signals different from each other, the video signal being supplied to pixel electrodes adjacent to the arbitrary pixel electrode on both sides thereof in a vertical scanning direction. A signal line driving IC outputs the video signal to each signal line group obtained by dividing a plurality of signal lines to a plurality of signal line groups composed of a predetermined number of the signal lines. A signal line switching circuit switches all of the signal lines in each signal line group sequentially during one horizontal scanning period.
