。[Scope of Claim for Utility Model Registration] For vehicles in which the displayed image of a display device with its display surface facing the windshield is reflected toward the driver's seat side by a reflective member on the dash board, so that the displayed image can be viewed from the driver's seat. In the display device, the prism is provided in front of the display device with the side where the gap between the entrance surface and the exit surface of the prism becomes narrower upward, and the light from the display device is directed to the entrance surface of the prism by the entrance surface of the prism. A display device for a vehicle, characterized in that the angular range of light that is refracted within a critical angle of total reflection and emitted to the reflective member side is regulated.
