  • 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. The first mirror layer is formed on both a region in which the plurality of mirror patterns are formed and a region in which the plurality of mirror patterns are not formed. External light is incident to and reflected by the first mirror layer, thus reducing an image haze and enhancing a display quality of the display device. In addition, the first mirror layer and the plurality of mirror patterns may be formed by using a single halftone mask to simplify the manufacturing process and increase a productivity of the mirror substrate.
