Abstract
A liquid crystal device is sequentially illuminated with three primary color lights in three primary color illumination steps including an off period (1) before, (2) before and after and (3) after the primary color light period, respectively. As a result, each primary color light illumination step includes a black picture display period corresponding to the off period, whereby motion picture blurring and color splitting can be suppressed without requiring a complicated circuit for generating new data for the black picture display.
