A head-up display apparatus configured to project an image on a windshield to display a virtual image to a driver includes an image display unit including a light source and a display element and configured to form the image. A display device is configured to project and reflect image light onto the windshield to display the virtual image in front of the windshield. A driver's viewpoint detector is configured to detect a viewpoint of the driver; and a movement mechanism is configured to move a position of the virtual image based on information of the viewpoint of the driver detected by the driver's viewpoint detector. The driver's viewpoint detector detects the viewpoint of the driver by irradiating the face of the driver with the interior light or light of the light source of the image display unit as illumination light at night.
