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.
