A vehicle information display system includes a head-up display for reflecting an image on a windshield of a vehicle and displaying the image so that a driver recognizes the image as a virtual image. Information is collected for being displayed by the head-up display. A circumstance of the vehicle, a circumstance of surrounding of the vehicle, or a circumstance of the driver is detected. The collected information is classified in accordance with a detection result. Then, display contents of the head-up display are controlled in accordance with a classification result.

Vehicle information display system

Provided is a head-up display having a prism sheet interposed between a display device and the position of an observer's eye. Control is extended so that points from which light rays having different wavelengths emerge are made different by a predetermined distance from each other so as not to form images at different points by light rays from a point source, relative to the difference between the wavelengths. Otherwise, a distance to an image in a vertical direction is made shorter by a predetermined distance than a distance thereto in a horizontal direction. The vertical angle of each of prisms included in the prism sheet is asymmetrical to a normal to the surface of the prism sheet.
