Abstract
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.
