DISPLAY SYSTEM

A display system includes: a display device in a mobile body; a concave mirror for displaying, in a first mode, a virtual image of a display image shown by image light emitted by the display device; and a plane mirror for reflecting, in a second mode, a rear-view image shown by light that has entered the mobile body. In a top view of the mobile body, the display device and the concave mirror are disposed such that a straight line connecting centers of the display device and the concave mirror has a predetermined angle relative to a front-and-rear direction of the mobile body. A normal direction at a center of a concave mirror surface of the concave mirror when the first mode is functioning and a normal direction normal to a plane mirror surface of the plane mirror when the second mode is functioning are not parallel.
