Abstract: A display device includes a substrate, a pixel circuit unit which is disposed on the substrate and having a first hole, a light blocking layer which is disposed on the pixel circuit unit and having a second hole corresponding to the first hole, a light emitting layer disposed on the pixel circuit unit, and a sealing unit on the light blocking layer. The substrate includes a first layer having a depression corresponding to the first hole, and a second layer which is disposed between the first layer and the pixel circuit unit and having a third hole between the depression and the second hole. The sealing unit includes a cover portion on the light blocking layer, and an extension portion extending from the cover portion. The depression has a width larger than a width of the third hole.

Abstract: An OLED display device includes a substrate. A first electrode is disposed on the substrate. An organic light emitting layer is disposed on the first electrode. A second electrode is disposed on the organic light emitting layer. A thin film encapsulation layer is disposed on the second electrode. The thin film encapsulation layer includes at least one inorganic layer and at least one organic layer that is disposed alternately with the at least one inorganic layer. The at least one organic layer includes a low refractive index layer overlapping the organic light emitting layer and a high refractive index layer disposed on the low refractive index layer. The high refractive index layer includes a convex surface protruding toward the organic light emitting layer.
