A screen device include a screen unit, onto which an image is projected and an infrared ray transmitting unit provided in the vicinity of the screen unit, for allowing infrared rays to pass therethrough. Since the infrared rays are allowed to pass through the infrared ray transmitting unit, the infrared rays emitted from a remote controller are guided from one side of the screen unit to other side thereof. Therefore, even though an apparatus to be controlled by the remote controller is installed behind the screen unit, the apparatus can be controlled by means of infrared rays emitted from the remote controller.
