Abstract:
A projection-type display apparatus includes a liquid crystal panel including a panel pixel, an optical path shifting element that shifts a projected pixel projected from the panel pixel, and a display control circuit that controls the liquid crystal panel and the optical path shifting element. The display control circuit supplies, to the liquid crystal panel, the same data signal and controls the projected pixel to be at a same position in a unit period f1-1 and a unit period f2-1 period, and controls the optical path shifting element to cause the position of the projected pixel in each of a unit period f1-2 to a unit period f1-4, to be different from the position of the projected pixel in a respective one of a unit period f2-2 to a unit period f2-4.
