摘要： 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.

摘要： A display device includes a substrate, a switching element on the substrate, a pixel electrode disposed on the switching element and connected to the switching element, a light emitting layer on the pixel electrode, a common electrode on the light emitting layer, and a sealing portion on the common electrode. The sealing portion includes an organic layer, and at least one first composite inorganic layer disposed between the organic layer and the common electrode. The at least one first composite inorganic layer includes a first inorganic layer between the common electrode and the organic layer, and a second inorganic layer between the first inorganic layer and the organic layer. A refractive index of the first inorganic layer and a refractive index of the second inorganic layer are different from each other, and the first inorganic layer and the second inorganic layer contact each other.
