ABSTRACT:
A display apparatus for a vehicle by which the brightness of a display image can be varied readily without using a dimming circuit and a display image of a high contrast can be assured. The display apparatus comprises a light emitting displaying element for emitting visible light therefrom, and a reflecting member for reflecting visible light from the light emitting displaying element toward a driver of the vehicle directly or indirectly by way of a component of the vehilce such as a windshield. The reflecting member is selectively moved between a first position at which the reflecting member totally reflects visible light from the light emitting displaying means and a second position at which the reflecting member reflects visible light from the light emitting displaying element but at a comparatively low reflecting rate.
