ABSTRACT:
A displaying apparatus for a vehicle in which a displaying device, for displaying various items such as a vehicle speed, an engine speed or the like, is disposed on the rear surface side of a semitransparent reflecting member arranged with an attitude oriented toward a driver's eye and a reflecting mirror is disposed at the position located opposite to the displaying device while the reflecting member is interposed therebetween so that virtual images appearing on the reflecting surface of the semitransparent reflecting member are visually recognized by a driver through a front glass. The reflecting member or reflecting mirror has wavelength selectivity which allows high reflectance only within the wavelength range defined for a color of displaying light emitted from a displaying device. Alternatively, the front glass has wavelength selectivity which allows high transmittance only within the wavelength range defined for the color of the displaying light emitted from the displaying device.
