ABSTRACT:
An automotive display apparatus displays synthetically an ordinary information like a vehicle speed value and a warning information like a remaining fuel amount by using a half mirror as a close range view and a distant range view. A control means determines contents of the ordinary information and the warning information on the basis of input signals from a plurality of sensors. When the warning information is displayed, the warning information is provided at a position that the warning information overlaps with the ordinary information in the line direction of a driver's sight and the warning information is away from the ordinary information by a predetermined distance to enable the driver to notice and observe the warning information easily. At the same time, the ordinary information at the overlap portion of the ordinary and warning information in the line direction of the driver's sight is inhibited from being displayed.
