Mirror having image display function

The present invention provides a mirror having an image display function and including, in the following order, an image display device, a circularly-polarized light reflective layer and a front surface panel comprising glass or plastic. The circularly-polarized light reflective layer includes a cholesteric liquid crystal layer. The cholesteric liquid crystal layer has a selectively reflective center wavelength in the visible light range, and the center wavelength and the wavelength of the light emission peak of the image display device differ by at least 5nm. The mirror having an image display function is capable of bright image display.
