Display device and display system

Abstract

A display device includes: a display that emits image light; an optical element that is disposed away from the display, the optical element being switchable between a first state in which the optical element reflects the image light and a second state in which the optical element transmits the image light; a first reflector that is disposed on an opposite side of the optical element relative to a side on which the display is disposed; and a controller that controls the display and the optical element. When the controller causes the display to repeatedly output a first image and a second image in an alternating manner, the controller switches the optical element between the first state and the second state in synchronization with the first image and the second image.
