A driving device for a liquid crystal panel having a signal generating circuit; a reference signal generating circuit; a phase comparator that compares phases of an inputted monitor signal and the reference signal and outputs phase comparison information; and an adder. The adder outputting an integrated count value for adjusting timing for generating the start signal on the basis of an initial count value set in advance and the phase comparison information from the phase comparator. The signal generating circuit generates plural timing signals including the start signal with the horizontal synchronizing signal as a trigger and with timing based on the integrated count value as a start point and supplies the timing signals to the liquid crystal panel.
