A driving device for a liquid crystal panel that includes: plural liquid crystal cells arranged in a matrix shape; pixel electrodes provided for the respective liquid crystal cells; plural data lines for inputting an image signal to the respective pixel electrodes; a data line driver that generates a sampling signal for sampling the image signal from inputted plural timing signals; plural sampling circuits provided for the respective data lines that sample the image signal according to the sampling signal and output the image signal to the data lines; and a dummy element formed on, at least, a substrate identical with a substrate on which the sampling circuits are formed, the driving device for a liquid crystal panel including: a signal generating circuit that generates, as the plural timing signals, a start signal and other signals generated with the start signal as a reference of a phase; a reference signal generating circuit that generates a reference signal with a horizontal synchronizing signal of an image signal as a trigger and with timing after elapse of a predetermined time as a start point; a phase comparator that compares phases of an inputted monitor signal and the reference signal and outputs phase comparison information; and an adder that outputs 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, wherein 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.
