Abstract

An organic light-emitting display apparatus and a method of manufacturing the same are provided. An organic light-emitting display apparatus includes: a substrate including an emission region and a non-emission region surrounding the emission region; a display device in the emission region of the substrate; an insulating layer in the non-emission region and including a hole having a lower portion having a first width and an upper portion having a second width less than the first width; and an encapsulation member covering the display device and the insulating layer and filling an inside of the hole.

Claims (35)

1. A display comprising:

a substrate comprising an emission region and a non-emission region surrounding the emission region;

a display device in the emission region of the substrate;

an insulating layer in the non-emission region and including a hole having a lower portion having a first width and an upper portion having a second width less than the first width; and

an encapsulation member covering the display device and the insulating layer and filling an inside of the hole,

wherein the display device comprises:

a first electrode;

a second electrode facing the first electrode; and

an emissive layer between the first electrode and the second electrode, and

wherein, in a plan view, the emissive layer is spaced apart from a region of the insulating layer in which the hole is defined.

2. The display of claim 1 , wherein, in all directions from a center of the hole, a distance from the center of the hole to a side surface of the lower portion of the hole is greater than a distance from the center of the hole to a side surface of the upper portion of the hole.

3. The display of claim 1 , wherein a distance from a side surface of the lower portion of the hole to a side surface of the upper portion of the hole is less than or equal to 1500 Å.

4. The display of claim 1 , wherein a height of the lower portion of the hole is less than a thickness of the insulating layer.

5. The display of claim 1 , wherein the insulating layer covers an edge of the first electrode, and

the second electrode extends over an upper surface of the insulating layer.

6. The display of claim 1 , wherein, in the hole of the insulating layer, a conductive material that is the same as a material of the second electrode is provided.

7. The display of claim 1 , wherein the encapsulation member comprises an inorganic layer.

8. The display of claim 1 , wherein the encapsulation member comprises a plurality of layers in which an inorganic layer and an organic layer are alternately stacked.

9. A display comprising:

a substrate;

a first electrode on the substrate;

a first insulating layer covering an edge of the first electrode and comprising an opening exposing a portion of the first electrode and a hole around the first electrode;

an intermediate layer disposed on the first electrode and comprising an emissive layer;

a second electrode covering the intermediate layer and the first insulating layer, a portion of the second electrode being disposed in the hole; and

an encapsulation member covering the second electrode and filling an inside of the hole,

wherein the hole has a lower portion having a first width and an upper portion having a second width less than the first width, and

wherein, in a plan view, the emissive layer is spaced apart from a region of the first insulating layer in which the hole is defined.

10. The display of claim 9 , wherein, in all directions from a center of the hole, a distance from the center of the hole to a side surface of the lower portion of the hole is greater than a distance from the center of the hole to a side surface of the upper portion of the hole.

11. The display of claim 9 , wherein a distance from a side surface of the lower portion of the hole to a side surface of the upper portion of the hole is less than or equal to 1500 Å.

12. The display of claim 9 , wherein a height of the lower portion of the hole is less than a thickness of the first insulating layer.

13. The display of claim 9 , wherein the encapsulation member comprises an inorganic layer.

14. The display of claim 9 , wherein the encapsulation member comprises a plurality of layers in which an inorganic layer and an organic layer are alternately stacked.

15. The display of claim 9 , further comprising:

a pixel circuit electrically connected to the first electrode; and

a second insulating layer between the first electrode and the pixel circuit.
