The present invention provides a head-up display apparatus capable of properly presenting information to a wide area. A head-up display apparatus includes: an image light output unit configured to output a first image display light formed by a visible light laser and a second image display light formed by an ultraviolet light laser; a screen that diffuses and transmits the first image display light, and transmits the second image display light without diffusing the second image display light; and a mirror that reflects the first and the second image display lights transmitted through the screen towards a windshield that presents a virtual image to a user by reflecting the visible light laser and presents a real image to the user by receiving the ultraviolet light laser and emitting light by itself.
