In at least one example embodiment, the output of the flip-flop becomes inactive regardless of whether a setting signal and a resetting signal are active or inactive, as long as the initialization signal is active. The initialization signal becomes active before the end of the simultaneous selection, and then becomes inactive after the end of the simultaneous selection. This makes it possible to stabilize operation of the shift register after the end of simultaneous selection of a plurality of signal lines carried out by the display driving circuit at a predetermined timing.
