Abstract:
1. A display device comprising: a display panel including a plurality of scanning lines, a plurality of data lines intersecting with the plurality of scanning lines, and a plurality of pixels provided separately near at respective intersections of the plurality of scanning lines and the plurality of data lines; a control signal output section outputting a control signal which alternately designates a scanning period in which a whole region of a screen of the display panel is scanned and a pause period in which an at least partial region of the screen is not scanned, wherein a sum of the number of frames constituting the scanning period and the number of frames constituting the pause period is an even number; a polarity designation signal output section outputting a polarity designation signal which designates a polarity of a data signal supplied to each of the plurality of data lines, the polarity designation signal being outputted in each of the frames in the scanning period and in each of the frames in the pause period while a polarity of the polarity designation signal is reversed every certain number of frame(s) within each of the scanning period and the pause period so that the polarity of the polarity designation signal (i) is reversed at a timing when switching from the scanning period to the pause period is carried out and is maintained at a timing when switching from the pause period to the scanning period is carried out or (ii) is maintained at a timing when switching from the scanning period to the pause period is carried out and is reversed at a timing when switching from the pause period to the scanning period is carried out; and a drive circuit supplying the data signal to the each of the plurality of data lines in the each of the frames in the scanning period, the data signal having a polarity based on the polarity of the polarity designation signal supplied to the drive circuit in the each of the frames.
