PROBLEM TO BE SOLVED: To improve a liquid crystal driving device so that control signals for converting picture signal to an AC signal do not exert adverse influence on the operation of a next vertical scanning period in a liquid crystal driving device in which the control signals are supplied even in a vertical blanking period. SOLUTION: In this liquid crystal driving device, a control signal corresponding to the final cycle of prescribed cycles in control signals which are supplied in the prescribed cycles is eliminated in the vertical blanking period.
