Abstract
In active driving of liquid crystal panels (R, G, and B) corresponding to R, G, and B color by X shift registers (R, G, and B) and Y shift registers (R, G, and B), alternating-current driving is performed such that signals to be written to the R color and B color liquid crystal panels are opposite in polarity to a signal to be written to the G color liquid crystal panel and also Vcom voltage of each of the liquid crystal panels is adjusted to thereby reduce flicker. The Vcom voltage supplied to the B color liquid crystal panel, for example, is finely adjusted to reduce flicker of a synthetic image of the liquid crystal panels.
