  • Patent number: 11740395
    Abstract: A display device may include a display unit disposed on a substrate and a mirror substrate facing the substrate with respect to the display unit. The mirror substrate may include a first mirror layer extending continuously on a surface of a transparent substrate and a plurality of mirror patterns on the first mirror layer.
