PROBLEM TO BE SOLVED: To provide a display system making a superimposed display enabling a driver to acquire a sense of distance. SOLUTION: The display system includes: a combiner 30 provided at the windshield 20 at the front of a vehicle; a plotting element 910; a short distance focusing optical system 930 receiving the incidence of an image displayed at the plotting element 910 and forming an image that gives a sense of first focal distance, on the combiner 30; a medium distance focusing optical system 940 giving a sense of second focal distance different from the first focal distance, on the combiner 30; a long distance focusing optical system 950 giving a sense of third focal distance different from the second focal distance, on the combiner 30; a focal distance changing shutter rotating body 920 integrally rotatably constituting the optical systems; and a control part for controlling the rotation of the focal distance changing shutter rotating body 920 so that the image displayed on the plotting element 910 is incident to one of the optical systems.
