A display device includes an image generation device configured to allow a viewer to recognize the image, a control device configured to control the image generation device, a light projector configured to output the image as light, an optical mechanism capable of adjusting a distance from a predetermined position to a position at which the light is formed as a virtual image, a concave mirror configured to reflect light passing through the optical mechanism toward a reflector, a first actuator configured to adjust the distance in the optical mechanism, and a second actuator configured to adjust a reflection angle of the concave mirror. The control device estimates a temperature of the light projector, and in a case in which the estimated temperature is equal to or higher than a predetermined upper limit temperature, the control device causes the first actuator to reduce the distance.
