<P>PROBLEM TO BE SOLVED: To drive a capacity line in accordance with writing polarity without using a polarity signal for specifying the writing polarity for a pixel. <P>SOLUTION: In a capacity line driving circuit 150, a second latch circuit 152 latches a signal held by itself when a scanning signal for a prescribed scanning line to be selected prior to a scanning line corresponding to one capacity line in one vertical scanning period is supplied. A first latch circuit 151 latches a signal corresponding to logical inversion of a signal having been latched by the first latch circuit 151 when a scanning signal for a prescribed scanning line to be selected after the scanning line corresponding to the capacity line in the vertical scanning period is supplied. A signal output circuit 154 supplies a first potential signal to the capacity line when the signal held by the first latch circuit 151 is at a first logic level and supplies a second potential signal to the capacity line when the signal is at a second logic level. <P>COPYRIGHT: (C)2012,JPO&INPIT |
