A head-up display apparatus adapted to project an image light beam onto a target element is provided. The head-up display apparatus includes a display unit, a diffusion device, and an optical system. The display unit is adapted to provide the image light beam comprising a first light beam and a second light beam. The diffusion device includes a first diffusion region and a second diffusion region, and optical structures of the first and the second diffusion regions are different. The first diffusion region and the optical system are located on a transmission path of the first light beam and guide the first light beam to the target element to form a first image. The second diffusion region and the optical system are located on a transmission path of the second light beam and guide the second light beam to the target element to form a second image.
