Abstract:
1. A display device comprising: a display portion that includes a plurality of video signal lines and a plurality of scanning signal lines crossing the video signal lines; a scanning signal line driver circuit that drives the scanning signal lines such that a scanning period in which the scanning signal lines are sequentially selected and an idle period in which none of the scanning signal lines is selected alternatingly occur in cycles of a frame period consisting of the scanning period and the idle period; a selection circuit that is integrally formed with the display portion and includes a plurality of selection blocks; a video signal line driver circuit that provides the selection blocks with their respective video signals; and a display control circuit that provides the video signal line driver circuit with image data corresponding to the video signals and provides the selection blocks with a plurality of selection control signals cyclically repeating on-state and off-state levels, wherein, each selection block provides the video signal received thereby to video signal lines that are adjacent to each other in a video signal line group in a time-division manner in accordance with the selection control signals, the video signal line group consisting of as many video signal lines as the number of selection control signals, and the display control circuit generates the selection control signals so as to keep the selection control signals at a lower frequency during the idle period than during the scanning period.
