A display system includes a transparent display body having a first surface and a second surface opposite to the first surface, a sensor to detect a brightness of the transparent display body or a brightness around the transparent display body, an arithmetic unit configured to derive, based on the brightness detected by the sensor, a background luminance caused by outside light as when the transparent display body is viewed from a side of the second surface, and a controller to cause video to be displayed on the first surface, wherein where rear show-through luminance that is a luminance of the video that occurs on the side of the second surface is denoted as BB and the background luminance is denoted as SB, the controller controls a video luminance in accordance with the background luminance derived by the arithmetic unit such that (BB/SB) is less than or equal to a predetermined contrast value, the video luminance being a luminance at which the video is to be displayed on the first surface.
