Abstract:
A display device includes a plurality of pixels arranged in a matrix. Overlapping areas between gate electrodes and drain electrodes of switching elements connected to a plurality of selected pixel electrodes are individually set to equalize or substantially equalize retention voltages Vd(+) (Vd(−)) of the selected pixel electrodes when a specific voltage of a first polarity is applied to the selected pixel electrodes. The source application section is controlled to apply to the source lines source signals Vsc each of which is corrected by superposing a correction voltage preset for each source line on the source signal Vs(−) (Vs(+)) in application of a voltage of a second polarity to the selected pixel electrodes.
