ABSTRACT:
A liquid crystal driving device that supplies control signals including at least a polarity inversion signal for AC driving to an image signal line driving circuit, the polarity inversion signal includes polarity inversion pulses varied periodically at a prescribed period even in vertical blanking intervals. The last polarity inversion pulses at the last cycles in each of vertical blanking intervals are deleted.
