A display device comprising: a display portion that includes a plurality of video signal lines (SL1,..., SLn) and a plurality of scanning signal lines (GL1,..., GLm) crossing the video signal lines (SL1,..., SLn); a scanning signal line driver circuit adapted to drive the scanning signal lines (GL1,..., GLm) such that a scanning period, in which the scanning signal lines (GL1,..., GLm) are sequentially selected, and an idle period, in which none of the scanning signal lines (GL1,..., GLm) 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 (410,..., 410(k)); a video signal line driver circuit adapted to provide the selection blocks (410,..., 410(k)) with their respective video signals; and a display control circuit adapted to provide the video signal line driver circuit with image data corresponding to the video signals and to provide the selection blocks (410,..., 410(k)) with a plurality of selection control signals cyclically repeating on-state and off-state levels, wherein each selection block (410,..., 410(k)) is adapted to provide the video signal received thereby to video signal lines (SL1,..., SLn) that are adjacent to each other in a video signal line group (SG1,..., SGk) in a time-division manner in accordance with the selection control signals, the video signal line group (SG1,..., SGk) consisting of as many video signal lines (SL1,..., SLn) as the number of selection control signals, characterized in that the display control circuit is adapted to generate the selection control signals such that the selection control signals also repeats cyclically on-state and off-state levels during the idle period and such that a period of the selection control signals during the idle period is set longer than a period of the selection control signals during the scanning period. a display portion that includes a plurality of video signal lines (SL1,..., SLn) and a plurality of scanning signal lines (GL1,..., GLm) crossing the video signal lines (SL1,..., SLn); a scanning signal line driver circuit adapted to drive the scanning signal lines (GL1,..., GLm) such that a scanning period, in which the scanning signal lines (GL1,..., GLm) are sequentially selected, and an idle period, in which none of the scanning signal lines (GL1,..., GLm) 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 (410,..., 410(k)); a video signal line driver circuit adapted to provide the selection blocks (410,..., 410(k)) with their respective video signals; and a display control circuit adapted to provide the video signal line driver circuit with image data corresponding to the video signals and to provide the selection blocks (410,..., 410(k)) with a plurality of selection control signals cyclically repeating on-state and off-state levels, wherein each selection block (410,..., 410(k)) is adapted to provide the video signal received thereby to video signal lines (SL1,..., SLn) that are adjacent to each other in a video signal line group (SG1,..., SGk) in a time-division manner in accordance with the selection control signals, the video signal line group (SG1,..., SGk) consisting of as many video signal lines (SL1,..., SLn) as the number of selection control signals,
