ツプデイスプレイ。[Claims for Utility Model Registration] An information projector comprising an optical information display means having a display surface on which information is displayed, and an optical member that projects information display light emitted from the display surface in a predetermined direction. and is installed at an angle in front of the pilot, and allows the light beam from the outside world to pass from the front to the rear so that the pilot can visually recognize the scene of the outside world in front of the driver, and also allows the light beam projected from the information projecting device to pass through from the front to the rear. A head-up display for a vehicle, comprising a combiner that reflects or diffracts the information display light in a direction visible to the driver, and the head-up display for a vehicle is configured to make the information display light visible to the driver at a predetermined display brightness. The information display means is composed of a light transmission amount control type display panel serving as a display surface, and a light source having cathode tubes arranged in a plurality of layers parallel to the display panel, and further controls overturning of each of the cathode tubes layer by layer. A vehicle head-up display characterized by being equipped with a light source control circuit.
