Abstract
A clock signal CK, picture data signals R·G·B and a source driver starting pulse signal SPI are cascade-connected between first through eighth source drivers in which eight source drivers LSI are cascade-connected. Each of the source drivers LSI is provided with an output control circuit which, up to the output of the start pulse signal SPI to the source driver LSI on the next stage or up to a predetermined time earlier than the output, stops the output of the clock signal to the source driver LSI at the next stage.
