The present display device is a display device for displaying a virtual image in front of a driver of a vehicle, the display device including an illuminance detecting unit configured to receive light surrounding the vehicle, and detect a brightness of the received light; an uptake angle restricting unit configured to restrict an angle of the light received by the illuminance detecting unit; an outside light correcting unit configured to adjust a luminance of a display image, according to the brightness of the light detected by the illuminance detecting unit; and an image displaying unit configured to display the display image by superimposing the display image on a field of vision of the driver as the virtual image, based on a result of adjusting the luminance, wherein an angle ¸2 at which the illuminance detecting unit receives the light is restricted by the uptake angle restricting unit, according to an angle ¸1 formed by light beams emitted from the virtual image toward eyes of the driver.
