A concave mirror of a reflective display device, which includes a reflector, a concave mirror arranged inside of an instrument panel, a display body, a lighting device, a display control circuit, driving parameters and the like, has reflecting surfaces with different wavelength selectivities, and the reflecting surfaces are formed into reflecting surface shapes of different focal lengths. By image light reflected selectively from the concave mirror, it is possible to present virtual images in different positions to an observer.
