Abstract
A display device for a motor vehicle includes an indicator 3 for providing a displayed image, arranged internally in the vehicle; a combiner 5 for reflecting image light of the displayed image toward an eye point I of a driver of the vehicle, a virtual image S of the displayed image which can be visually recognized from the eye point being displayed on the combiner 5; and meter units 9, 9 for displaying a status of the vehicle as a real image, the meter units being located between the combiner and the eye point at a position outside an optical path of the image light of the displayed image. The combiner 5 has a contour which can be visually recognized from the eye point and nearly surrounds the virtual image and a real image of the meter units 9, 9. In such a configuration, a display with a sense of unity between a real image and a virtual image can be realized while avoiding an increase of a dashboard in size and complication thereof in structure.
