To provide a unit room generating no loss on brightness and contrast without being affected by the external light by solving such problems that when an image is projected from a projector to a nontransparent dimming glass arranged in the front of an outside light window, the outside light from the outside light window largely affects the image, and a loss occurs on the brightness and contrast in the projection of the image because this nontransparency is not necessarily complete nontransparency.
When a reflector such as a mirror is installed on the back face of the dimming glass, most of the light quantity from the projector is reflected without loss, thereby the projected image is brightened, contrast is improved, and the effect of the external light on the back face can be prevented.
