Abstract
A projection-type display apparatus includes a liquid crystal panel, an optical path shift element, and a display control circuit that controls the liquid crystal panel and the optical path shift element. When a difference in gray scale level between pixel data corresponding to a panel pixel pand pixel data corresponding to a panel pixel p, the panel pixel pand the panel pixel pbeing two adjacent pixels, is equal to or larger than a threshold in a unit period-for example, the display control circuit corrects at least one of a gray scale level of a video pixel corresponding to the panel pixel pin a previous unit period-or a gray scale level of a video pixel corresponding to the panel pixel pin a unit period-to reduce a difference in luminance between the panel pixels.
