Abstract
The present invention relates to a display that uses a polysilicon liquid crystal panel. An object of the present invention is to sufficiently secure a hold period and a setup period upon a rise of a source start pulse signal (SSP) without increasing power consumption or increasing circuit scale. A display control circuit () includes a source start pulse signal generating circuit () that generates a source start pulse signal (SSP); and a source shift clock signal generating circuit () that generates a source shift clock signal (SCK). The source shift clock signal generating circuit () shortens a period during which the source shift clock signal (SCK) is maintained at a high level, only during a period of time which is immediately before the source start pulse signal (SSP) rises in each horizontal scanning period, based on a source shift clock modification command signal (K) to be outputted from the source start pulse signal generating circuit ().
