ABSTRACT:
A display device has first and second substrates, a liquid-crystal layer, pixel electrodes arranged on the first substrate, a plurality of semiconductor active elements connected to the pixel electrodes, signal lines for supplying drive signals to the active elements, and a plurality of opposing electrodes arranged on the second substrate. Each pixel electrode, that portion of each opposing electrode which overlaps the pixel electrode, and that portion of the liquid-crystal layer which is sandwiched between the pixel electrode and said that portion of the opposing electrode form a pixel. A voltage having a positive or negative value according to the image data is applied between the input terminal of the semiconductor active element and said at least one of the opposing electrode, for a selecting period. Also, a voltage having such a waveform that at least two components thereof which are positive and negative with respect to a non-selecting potential which the scan signal has during the non-selecting period, said at least two component having substantially the same area, is applied between the input terminal of the semiconductor active element connected to said at least one of the pixel electrodes and said at least one of the opposing electrode, for the non-selecting period.
