A head-up display includes a concave mirror actuator that changes, based on external instructions, a reflection angle by which a concave mirror reflects display light. A drawing unit includes a beam generator, a scanner, an optical actuator, and a controller, The beam generator emits a beam, and the scanner scans the beam in two dimensions by moving a reflection surface to draw an image. The optical actuator changes an angle of incidence of when the beam is emitted to the scanner. The controller drives the optical actuator to change the angle of incidence such that display light distortions generated at the concave mirror are offset by display light distortions generated at the scanner.
