Abstract: A device capable of switching between an image display state and a mirror state is provided. The device includes an image display portion and a mirror portion. The image display portion emits image light for displaying a desired image and includes a display panel. The mirror portion is superposed on the image display portion and can switch between an image transmittance state for transmitting image light and a mirror state for reflecting outside light. The mirror portion includes a liquid crystal layer disposed between a first glass substrate and a second glass substrate and a reflective polarization layer adhered to the second glass substrate. A reflective enhancement layer separate from the reflective polarization layer is disposed between the display panel and the liquid crystal layer and has a refractive index that is different from the refractive index of the second glass substrate.
