ABSTRACT:
A liquid crystal display device having a plurality of pixels arranged in a matrix, a plurality of video signal lines for supplying video signal voltages to the plurality of pixels and a drive circuit for selecting a voltage level of a gray scale voltage varying periodically, as one of the video signal voltages corresponding to display data to be supplied to one of the plurality of pixels. The drive circuit has a plurality of series combinations of plural processing circuits, each of the plurality of series combinations of plural processing circuits corresponding to one of the plurality of video signal lines, each of the plural processing circuits includes a switching element which is activated by the display data and a respective one of the plurality of series combinations of the plural processing circuits determines a time to select the voltage level.
