ABSTRACT:
A display apparatus for an automotive vehicle for displaying a vehicular driving information, such as vehicle speed, fuel amount, engine coolant temperature and so forth, includes a light shield interpositioned between a semi-transparent projector panel, on which information containing virtual image is formed, and a transparent panel which covers a cavity formed in an instrument panel for receiving an optical image projector device. The transparent panel is so designed as to reflect lights, such as sun beam toward the light shield. With this construction, the sun beam and so forth reflected by the transparent panel can be absorbed by the light shield to maintain contrast of the virtual image formed on the projector panel satisfactorily high and thus may not affect to visibility of the displayed image.
