A scanning signal is precisely output to a scanning signal line corresponding to a row range even in a case where a plurality of scanning signals (including a precharge signal) are output at the same time. A display control circuit of the display device sets row selection, enable signals at H level so that main charging periods are set in a range from an ith row to an mth row, which corresponds to a moving image region, and precharging periods corresponding to the main charging periods are also set. Accordingly, a precise scanning signal in which a precharging period having a necessary length is set and no unnecessary precharging period is set at all is output to each of scanning signal lines connected to a scanning signal line driving circuit, so that deterioration of display quality is prevented. |

1. A display device that displays an image by a plurality of pixel forming parts that are arranged along a plurality of video signal lines with which a plurality of video signals are transmitted and a plurality of scanning signal lines that intersect with the plurality of video signal lines, the display device comprising:
a video signal line driving circuit that drives the plurality of video signal lines based on an image signal that indicates the image; a scanning signal line driving circuit that outputs a main selection signal, with which the plurality of scanning signal lines are individually selected per unit selection period in turn in order to cause the plurality of pixel forming parts to display the image, and a preliminary selection signal, with which the plurality of scanning signal lines are individually selected in turn during (n−1) (n is a natural number equal to or more than 2) unit selection period immediately before the main selection signal in order to perform preliminary charging before displaying the image, to each of the plurality of scanning signal lines so that phases are different between unit selection periods; and a display control circuit that controls the video signal line driving circuit and the scanning signal line driving circuit, wherein the display control circuit supplies, to the scanning signal line driving circuit, at least n row selection enable signals with which selection of a range of the plurality of scanning signal lines, which is designated from an outside of the device, is permitted, and causes a scanning signal line in the range to output the main selection signal and the preliminary selection signal and causes a scanning signal line outside the range to output neither the main selection signal nor the preliminary selection signal. |
