Upon each detection of an image switch by a display switch detection portion (27) included in a display control circuit (200), a selection frequency determination portion (23) makes a determination for each row corresponding to a scanning signal line as to whether or not the row includes any pixel with a middle tone. Further, a scanning signal output control portion (26) performs drive control such that any scanning signal line corresponding to a row without such a pixel is selected at intervals of one frame period. This results in reduced power consumption in selecting the scanning signal lines.
