Abstract: An information display apparatus capable of reducing the viewpoint movement of a driver and achieving safer driving in consideration of the relationship between the traveling speed and the stopping distance of a vehicle is provided. The information display apparatus is configured to display image information in a transportation and comprises a HUD apparatus disposed between a windshield of the transportation and an instrument panel of the transportation. The HUD apparatus detects a viewpoint position of a driver; and displays a virtual image of the image information in front of the transportation by reflecting light emitted from the HUD apparatus to display the image information by the windshield. The HUD apparatus is configured to set a display position of the virtual image in accordance with movement of the viewpoint position of the driver who is driving the transportation.
