An indication display unit for a vehicle, includes a reflecting device having a reflecting surface directed to a driver's seat which reflecting surface has a reduced reflectivity. An indicating device having an indicating surface directed to the reflecting surface of the reflecting device. Operational information concerning driving operation of the vehicle is indicated on the indicating surface of the indicating device, and is reflected on the reflecting surface of the reflecting device to be visibly observed by a driver. As the reflectivity of the reflecting surface is reduced, the visibility of the displayed image from the indicating surface may be improved. Since the reflecting device is provided on a dashboard, and the indicating device is located at any position other than the dashboard, a meter hood may be removed to ensure more space in the dashboard. The reflecting device is composed of a reflecting plate and a frame for supporting the reflecting plate, which is preliminary curved with a relatively good accuracy. In constructing the reflector, the reflecting plate is cured by forcibly following the curvature of the frame, thereby easily obtaining a curvature of the reflecting plate with a relatively good accuracy.

An automotive display system for a vehicle comprises a display having a display screen, a reflecting mirror disposed with its reflecting surface facing the display screen of the display, and a prism disposed between the display and the reflecting mirror. Light rays emanated from the display enter the prism through a first surface of the prism, are transmitted through the prism and fall on the reflecting surface of the reflecting mirror and are reflected by the reflecting mirror. The light rays reflected by the reflecting mirror travel along a path coinciding with or nearly coinciding with the path of travel of the light rays incident on the reflecting surface of the reflecting mirror and are reflected again by the second surface of the prism toward the driver's eye. The light rays travel from the second surface of the prism to and from the reflecting mirror through a comparatively long optical path in a relatively small space for effective remote displaying. Thus, the automotive display system can be formed in a compact construction.
