a display panel which is switchable between an image display mode and a transmissive mode, the image display mode being a mode in which an image is displayed on the display panel, the transmissive mode being a mode in which the display panel is in a transmissive state where a back side of the display panel is visible in a front view of the display panel;
a frame body including a top wall, side walls, and a bottom wall and forming a space portion which is provided behind the display panel;
one or more objects arranged on the bottom wall;
an illuminator which is disposed outside of and behind the display panel, and emits illumination light to the space portion;
a controller which controls the illuminator; and
an illuminance detector which detects an ambient illuminance of the image display device,
wherein, when the display panel is operating in the transmissive mode, the controller performs illumination control for causing the illuminator to emit illumination light with a brightness that is in accordance with a result of detection by the illuminance detector, and the one or more objects are observable through the display panel; and wherein:
the display panel includes:
an image display panel which displays an image when the display panel is operating in the image display mode; and
a light control panel which is disposed behind the image display panel, and is switchable between a transmissive state and a non-transmissive state, the transmissive state being a state where light is transmissive through the light control panel, the non-transmissive state being a state where light is not transmissive through the light control panel,

the controller further performs the illumination control according to the result of the detection, when the display panel operates in the image display mode and the light control panel is in the transmissive state, and
the illuminator is disposed in at least one of the top, side and bottom walls, at a position behind the display panel to emit the illumination light to the space portion.
