Abstract: The present invention provides a mirror display system that enables simultaneous perception of a mirror image and a video image with suppressed uncomfortable feeling. The mirror display system of the present invention includes a half mirror plate including a half mirror layer; a 3D display device; and a control unit being configured to supply a video signal to the 3D display device. The 3D display device is disposed on the back surface side of the half mirror plate and is configured to display, by the video signal, a video image for the left eye and a video image for the right eye that give a parallax on a display surface of the 3D display device. The parallax is set such that a fused video image of the video image for the left eye and the video image for the right eye is perceived on the back surface side behind the display surface of the 3D display device.
