US 10,371,986 B2 · Display devices including mirror substrates and methods of manufacturing mirror substrates

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.

Dependent claims

A display device comprising:

a display unit disposed on a substrate and having an emitting region and a non-emitting region;
and
a mirror substrate facing the substrate with respect to the display unit, the mirror substrate including:
a first mirror layer extending continuously on a surface of a transparent substrate and having a planar surface throughout the emitting region and the non-emitting region of the display unit;
and
a plurality of mirror patterns arranged on the first mirror layer,
wherein the first mirror layer is interposed between the transparent substrate and the mirror patterns in the non-emitting region, and
wherein a reflectivity of the first mirror layer is less than a reflectivity of the plurality of mirror patterns.
