Abstract
A head-up display apparatus includes a display panel configured to display an image, and a reflecting mirror configured to reflect light from the display panel. An optical distance between the reflecting mirror and the display panel is changed to continuously change a display position of a virtual image from a distant place to an adjacent position such that a virtual image obtained by being reflected at an upper portion of a windshield is formed farther than a virtual image obtained by being reflected at a lower portion of the windshield when viewed from a viewpoint position of a driver.
