Abstract

Official abstract text for this publication.

A display device includes: a substrate; a display unit on the substrate; a first inorganic layer on the display unit; a first organic layer on an upper portion of the first inorganic layer; a first dam at an edge of the first organic layer; a second dam spaced from the first dam and at an outer area of the first dam with respect to the display unit; and a stress relieving layer between the first dam and the second dam.

First claim

Opening claim text (preview).

What is claimed is: 1. A display device comprising: a substrate; a display unit on the substrate and configured to emit light; a first inorganic layer on the display unit; a first organic layer on the first inorganic layer; a second inorganic layer on the first organic layer, the second inorganic layer directly contacting the first inorganic layer outside of the first organic layer; a first dam overlapping with at least a portion of the first organic layer; a second dam spaced from the first dam and at an outer region of the first dam with respect to the display unit; a second organic layer above the first dam; and a conductive layer overlapping with at least a portion of the second organic layer; wherein respective edges of the first inorganic layer and the second inorganic layer are located between the first dam and the second dam. 2. The display device of claim 1 , wherein the conductive layer comprises a ELVSS. 3. The display device of claim 2 , wherein the first dam overlaps with the ELVSS. 4. The display device of claim 1 , wherein the second organic layer comprises an organic material. 5. The display device of claim 1 , wherein the second organic layer comprises a same material as that of the first organic layer. 6. The display device of claim 1 , wherein the second organic layer is formed using an inkjet process. 7. The display device of claim 1 , further comprising a protection film below the substrate. 8. The display device of claim 7 , wherein the protection film is spaced from a display area and is inside a display area of the display device. 9. The display device of claim 7 , wherein an upper edge of the protection film is rounded. 10. The display device of claim 7 , wherein the substrate has a notch, and wherein the notch is spaced from an edge of the protection film. 11. The display device of claim 1 , wherein the second organic layer overlaps with the first inorganic layer between the first dam and the second dam. 12. The display device of claim 1 , wherein the second organic layer overlaps with the second inorganic layer between the first dam and the second dam. 13. The display device of claim 1 , wherein the second dam overlaps with at least a portion of the second organic layer. 14. The display device of claim 1 , wherein the conductive layer, the first dam, and the second organic layer comprise a region overlapping in a direction crossing the substrate.
