Abstract

In a liquid crystal projector, in a first liquid crystal panel corresponding to a first color, a gray scale level specified by video data specifies a first value in a first field, and a second value in a second field subsequent to the first field, and in a second liquid crystal panel corresponding to a second color, a gray scale level specified by the video data specifies the first value in the first field, and the second value in the second field. When optical responsiveness of the first liquid crystal panel is better than optical responsiveness of the second liquid crystal panel, in the second field, a liquid crystal voltage applied to the first liquid crystal panel is smaller than a liquid crystal voltage applied to the second liquid crystal panel.
