A mirror with an image display function includes in order: an image display device; a ¼ wavelength plate; a circular polarization reflection layer; and a front surface plate, the front surface plate includes a substrate and an inorganic reflection layer, the inorganic reflection layer is a semi-transmissive semi-reflective layer, the circular polarization reflection layer includes a cholesteric liquid crystal layer, and the cholesteric liquid crystal layer has a central wavelength of selective reflection in a visible light region. The half mirror includes in order: the ¼ wavelength plate, the circular polarization reflection layer, and the front surface plate.
