Abstract
A projection display device including a first liquid crystal panel that generates a first image, a second liquid crystal panel that generates a second image, a prism that combines the first image with the second image shifted in a horizontal direction with respect to the first pixel and outputs a combination image, a light path shift element, and a display control circuit that controls the first liquid crystal panel, the second liquid crystal panel and the light path shift element. The display control circuit supplies a data signal of a first color component in an odd-numbered row of video pixel data to the first liquid crystal panel in a first unit period, and supplies the same data signal of the same first color component in an even-numbered row of the video pixel data to the first liquid crystal panel in a second unit period.
