ABSTRACT:
The automotive display apparatus consists of an indicator, a transmissive first reflector plate, a second reflector plate, and a face plate. The face plate has a rear surface the upper portion of which is inclined at an angle larger than the inclined angle of the remaining portion of the rear surface. If light from a display of the indicator is inadvertently directly passed onto the upper portion of the rear surface of the face plate, the upper portion reflects the light to form an eventually ghost-causing virtual image at such a position that the ghost does not enter into a viewing area for the indicator display. The automotive display apparatus does not require an extra spc to provide a display free of ghost and is produceable at a low cost.
