A display apparatus includes a display element, an optical element, a projection optical system, a driver, and a controller. The display element includes a display surface having subpixels arranged in a grid pattern along a first direction and a second direction approximately orthogonal to the first direction. The optical element is configured to define a beam direction of image light emitted from the subpixels in each of strip-shaped regions that extend in the second direction on the display surface. The projection optical system is configured to project image light having the beam direction defined by the optical element to form a virtual image of the display surface. The driver is configured to displace the optical element. The controller is configured to displace the optical element using the driver.
