After a voltage of opposite polarity is applied between electrodes of liquid crystal shutters for each of an odd number of colored lights emitted cyclically, a dummy operation of the liquid crystals is performed during a wait period until a next write command pulse is received. During the dummy operation, LEDs which emit the colored lights are kept off. Delays in response of the liquid crystals are reduced by driving the liquid crystals continuously, and molecular arrangement in the liquid crystals is kept constant whenever possible by performing an even number of shutter operations and thereby driving the liquid crystals for the same color with a voltage of the same polarity.
