In this display device the information required for driving which is displayed by an instrument and the like is reflected on the windshield of the automobile and superimposed on the foreground so that the driver can visually confirm the information, the double image is formed because the images reflected on the inside surface 2 and the outside surface of the windshield are deviated. The double image can be eliminated by laminating a wedged transparent body 8 whose upper side is thick on the surface 2 of the windshield so that the reflected image on a display unit P1 reflected on the surface of the transparent body 8 and that on the outside surface of the windshield may be viewed in the same direction from the driver.
