The present invention provides a mirror display which prevents the boundary line between a frame region and a display region from being observed in a mirror mode and which thus has improved design quality. The mirror display of the present invention includes a half mirror plate including a half mirror layer, and a display device disposed behind the half mirror plate, the display device including a display panel and a frame component that supports a peripheral portion of the display panel, and the mirror display including a reflectance adjuster that makes equal the reflectance in a display region where the half mirror layer and the display panel face each other and the reflectance in a frame region where the half mirror layer and the frame component face each other.
