Abstract
When, in a liquid crystal projector, optical responsiveness of a liquid crystal panel corresponding to G is better than optical responsiveness of a liquid crystal panel corresponding to R, a display control circuit performs a tr correction and a tf correction of overdrive processing for R, and performs only the tr correction of the overdrive process for G, and does not perform the tf correction for G. The display control circuit performs a black floating process for R, G, and B.
