a display including a display surface on which video is displayed and being switched between ON and OFF;
a reflectance control device positioned on a display surface side of the display and configured to change a reflectance for incident light; and
a control circuit configured to control
the reflectance of the reflectance control device,
switching between ON and OFF of the display, and
the video displayed on the display surface, wherein

the reflectance control device includes a first part and a second part, the first part being positioned in a first region overlapping the display surface when viewed in a normal direction, the normal direction being normal to the display surface, the second part being positioned in a second region surrounding the first region when viewed in the normal direction of the display surface,
the control circuit controls a reflectance of the second part based on at least one of speed information indicating a speed of the vehicle or reverse information indicating whether the vehicle is reversing, and
when the display is OFF, the control circuit controls the reflectance control device such that the reflectance of the second part is lower than a reflectance of the first part.
