An on-vehicle display used in automotive vehicles for displaying an image projected from within a dashboard of a vehicle. A first reflecting surface on a windshield of a vehicle. The first reflecting surface is at a first angle with the dashboard. A second reflecting surface on a reflector is mounted in the proximity to a lower end portion of the windshield. The second reflecting surface is at a lower position than the first reflecting surface and at a second angle with the dashboard. A vehicle speed sensor for outputting a vehicle speed signal indicative of said vehicle speed to said controller. A controller guides the image projected from within the dashboard either to the first reflecting surface or to the second reflecting surface depending on a vehicle speed. A photodetector outputs a light intensity signal indicative of an intensity of ambient light in the proximity to the windshield. A controller receives the light intensity signal from the photodetector and guides the image projected from within the dashboard to the second reflecting surface when the light intensity signal is outside a predetermined range.
