A projection apparatus including an illumination module, a display panel, and a projection lens module is provided. The illumination module includes a light source assembly including a light guide plate, a light source, a reflector, and a reflective polarizer, and a polarized beam splitter (PBS). The light guide plate has a light emitting surface, a bottom surface opposite to the light emitting surface, and a light incident surface connected between the light emitting surface and the bottom surface. The light source, the reflector, and the reflective polarizer are faced to the light incident surface, the bottom surface, and the light emitting surface respectively. The PBS is disposed beside the reflective polarizer away from the light guide plate. The display panel and the light source assembly are respectively located at two adjacent sides of the PBS. The projection lens module is disposed beside the PBS away from the display panel.
