Abstract: The present invention provides a mirror display that can be enlarged without quality deterioration. The mirror display includes, in the order from a viewing surface side, a half mirror plate including a reflective polarizer, a polarization conversion layer, and a display device including an absorptive polarizer on a side of the polarization conversion layer. The reflective polarizer includes a transmission axis parallel to the longitudinal direction of the display device and is jointless. The absorptive polarizer includes a transmission axis perpendicular to the longitudinal direction of the display device and is jointless. The polarization conversion layer is configured to convert the polarization of polarized light passed through the absorptive polarizer.
