Abstract:
The head-up display includes an imaging position changer configured to change a position of a virtual image between a far visual position far from an observer and a near visual position close to the observer. The imaging position changer inclines the virtual image at the far visual position by a second inclination angle with respect to a perpendicular plane to a reference light beam reaching a center of a viewpoint region in which a viewpoint of the observer is located, to move an upper end thereof in a forward direction of the moving object, and inclines the virtual image at the near visual position by a first inclination angle smaller than the second inclination angle with respect to the perpendicular plane to the reference light beam, to move the upper end in the forward direction of the moving object.
