摘要

A stage of the shift register has (i) a set-reset type flip-flop which receives an initialization signal (INITB) and (ii) a signal generating circuit which receives a simultaneous selection signal (AONB) and which generates an output signal (OUT) by use of an output (Q) of the flip-flop. The output (Q) of the flip-flop becomes inactive regardless of whether a setting signal (SB) and a resetting signal (R) are active or inactive, as long as the initialization signal (INITB) is active. The initialization signal (INITB) 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.
