A display device includes a light projection device which projects light including an image, an optical mechanism which is capable of adjusting a distance from a predetermined position to a position where the light is formed as a virtual image, a concave mirror which reflects light toward a reflector, a concave mirror actuator which adjusts a reflection angle of the concave mirror, and a control device which controls the light projection device and the concave mirror actuator, in which the control device adjusts a projection position on a projection surface of the light projected from the light projection device having an angle formed by a horizontal surface passing through a predetermined position on an image and a segment from the predetermined position to a position where the light is formed as a virtual image so as to curb fluctuation occurring due to movement of a vehicle.
Display device, control method for placement of a virtual image on a projection surface of a vehicle, and storage medium
