<p>Provided is a display device which allows vivid observation of an exhibit and video displayed on a screen. When a synchronization control unit (31) switches a screen (21) to a scattering mode, the synchronization control unit (31): outputs, to a lighting device (41), lighting control information for causing the lighting device (41) to darken; and outputs, to a projector (11), projection cont rol information for causing video light to be projected from the projector (11) to the screen (21). When the screen (21) is switched to a transmission mode, projection control information for causing projection of video light from the projector (11) to stop is outputted to the projector (11), and lighting control information for causing the lighting device (41) to light up is outputted to the lighting device (41).</p> |
