Patent ID: 8587509

Claim:
An active-matrix display device with a plurality of pixel formation portions for forming an image to be displayed, a plurality of video signal lines for transmitting signals representing the image to be displayed, and a plurality of scanning signal lines crossing the video signal lines, the plurality of pixel formation portions being arranged in a matrix so as to correspond to their respective intersections of the video signal lines and the scanning signal lines, the device comprising: a scanning signal line drive circuit configured to selectively drive the scanning signal lines; a video signal line drive circuit configured to drive the video signal lines by applying image signals inputted as the signals representing the image to be displayed, in predetermined order via a plurality of groups of switch elements, each group being provided so as to correspond to one of the video signal lines and consisting of a plurality of switch elements connected in parallel; and a display control circuit configured to control the switch elements such that, at least one of the switch elements in the same group is on during a period required for providing a corresponding image signal to a corresponding video signal line, a time point at which a part of the switch elements in the same group is turned off varies from a time point at which the remaining switch elements are turned off, and for each horizontal scanning period, the switch elements in the same group are turned on at approximately the same time, with a part of the group being the last to be turned off.
