Abstract
A display device for use in a vehicle is provided, by which an image for superposition displayed on a display source is projected on a windshield of a vehicle so that the foreground of the vehicle and a virtual image of the image for superposition are accurately seen together even when a seat position and a physique of a driver change and when a shape of the windshield changes. A light of inverse image for superposition displayed on a display surface of a display unit in a dashboard in a vehicle is projected on a windshield so that the driver sees the foreground visible through the windshield together with a virtual image of the inverse image for superposition reflected on the windshield in front of an eye point I, that is, a virtual image of the original image for superposition. In order to cancel out distortion arisen when the light of the inverse image for superposition is reflected on the windshield , the inverse image for superposition displayed on the display unit is distorted in advance in response to the contents stored in an external ROM provided in a control unit , which is replaceable with another ROM storing the different contents.
