Abstract
A display system has a display unit and a reflector which are disposed in an instrument panel of an automotive vehicle. The display unit emits an image that is reflected by the reflector, and the image is projected on a windshield of the vehicle via an opening of the instrument panel. The display system superposes the image on a foreground seen from the vehicle such that a diver of the vehicle can recognize the superposed image and the foreground via the windshield simultaneously. The display system includes a shutter device disposed between the display unit and the opening. The shutter device is transformable to pass indication beams of the emitted image through the opening in conformity with a size of the emitted image.
