<p>In this reflective display device, which is configured of a reflector, a concave mirror, a display, an illuminating device, a display control circuit, an operation parameter detection device and the like, said concave mirror, display, illuminating device, display control circuit and operation parameter detection device being disposed inside of an instrument panel, the concave mirror has a reflecting surface having different wavelength selectivities, and the reflecting surface is configured of reflecting surface shapes respectively having different focal point distances. Virtual images can be presented at different positions to an observer by means of image light selectively reflected by means of the concave mirror.</p> |
