Display panel and method of manufacturing the same
A display panel includes a substrate including an opening and a display area surrounding the opening, a light-emitting element in the display area and including a first electrode, an intermediate layer, and a second electrode, a multi-layered dam in a non-display area between the opening and the display area, an encapsulation layer extending substantially over the display area and the non-display area, and a first layer pattern disposed in one area of the non-display area.
1. A display panel comprising:
a substrate having an opening and a display area surrounding the opening;
a light-emitting element in the display area and including a first electrode, an intermediate layer, and a second electrode;
a multi-layered dam in a non-display area between the opening and the display area;
an encapsulation layer extending substantially over the display area and the non-display area; and
a first layer pattern disposed in one area of the non-display area and having a bottom surface coplanar with a corresponding bottom surface of the multi-layered dam.
2. The display panel of claim 1 , wherein the first layer pattern is disposed in at least one of the non-display area adjacent to the multi-layered dam or the non-display area adjacent to the opening.
3. The display panel of claim 1 , wherein the first layer pattern is arranged in the one area of the non-display area in a discontinuous linear pattern or a discontinuous curved pattern.
4. The display panel of claim 1 , wherein the first layer pattern is arranged in the one area of the non-display area in a continuous linear pattern or a continuous curved pattern.
5. The display panel of claim 1 , wherein the first layer pattern comprises a sacrificial layer pattern having the same material as that of the first electrode.
6. The display panel of claim 1 , wherein at least one inorganic encapsulation layer in the encapsulation layer covers the first layer pattern.
7. The display panel of claim 1 , wherein the opening extends completely through the substrate.
8. The display panel of claim 1 , wherein the multi-layered dam comprises:
an insulating layer on the substrate;
a first organic insulating layer directly contacting the insulating layer; and
a second organic insulating layer directly contacting the first organic insulating layer.
9. The display panel of claim 8 , wherein
the intermediate layer overlaps the multi-layered dam and directly contacts the insulating layer, the first organic insulating layer, and the second organic insulating layer.
10. The display panel of claim 1 , wherein the intermediate layer overlaps and directly contacts the multi-layered dam.
11. The display panel of claim 1 , wherein
the bottom surface of the multi-layered dam extends between and ends at first and second side surfaces of the multi-layered dam.
12. The display panel of claim 11 , wherein the bottom surface of the first layer pattern and the bottom surface of the multi-layered dam directly contact an upper surface of a second interlayer insulating layer.
13. The display panel of claim 1 , wherein
the first layer pattern is spaced apart from the multi-layered dam in a horizontal direction by the intermediate layer overlapping the multi-layered dam in a thickness direction.
14. The display panel of claim 13 , wherein
the first layer pattern is spaced apart from the multi-layered dam in the horizontal direction by an inorganic encapsulation layer overlapping the multi-layered dam, the first layer pattern, and the intermediate layer in a thickness direction.
15. The display panel of claim 1 , wherein the encapsulation layer directly contacts an upper surface of the first layer pattern, and the encapsulation layer is an inorganic encapsulation layer.
