Abstract: A display device includes a substrate, a pixel electrode, an encapsulation layer, and a light-shielding layer. The pixel electrode is positioned above the substrate. The encapsulation layer is disposed over the pixel electrode. The encapsulation layer includes a first inorganic layer. The first inorganic layer includes a plurality of fine pillar patterns. The pillar patterns are sloped with respect to one surface of the substrate. The light-shielding layer is disposed on the encapsulation layer. The light-shielding layer includes a first opening. The first opening overlaps at least a portion of the pixel electrode.
