A projection optical system applicable to a head-up display device mounted on an automobile includes an image generation unit, a first reflection unit, a double-telecentric lens, a light splitting device, a second reflection unit, a first lens, a third reflection unit, and a second lens that are successively arranged in a light exit direction. The light splitting device is arranged on an image side of the telecentric lens. The image generation unit is capable of simultaneously emitting light beams including image information of a first image and a second image in different contents. In response passing through the first reflection unit, the double-telecentric lens, and the light splitting device, the light beam of the first image exiting from the second reflection unit is projected and imaged, and the light beam of the second image exiting from the third reflection unit is projected and imaged.
