The image source is used for emitting an image light beam. The polarizer, the first wave plate, the transflective element, the first lens, the second wave plate, the reflective polarizer, and the second lens are sequentially disposed on a path of the image light beam. The light guiding unit has a reflective surface. The curved transflective film is disposed on the light guiding unit. After being incident on the light guiding unit, the image light beam is sequentially reflected by the reflective surface and the curved transflective film to the eye of the user.
