Abstract
Provided is a mirror display device including a monitor display element for emitting image light vibrating in a first direction in an image display state; and a mirror optical element provided on the display surface side relative to the monitor display element. The mirror optical element can switch reflective and transmissible states. The reflective state is that light vibrating in a first direction from an absorption-type polarization plate side is converted to vibrate in a second direction by a liquid crystal cell to be reflected by a reflection-type polarization plate, and converted to vibrate in the first direction by the liquid crystal cell to be emitted from the absorption-type polarization plate. The transmissible state is that light vibrating in the first direction from a reflection-type polarization plate side is transmitted through the cell as it is, to be emitted from the absorption-type polarization plate.
