Abstract

A display device includes: a substrate having an opening area, a display area at least partially extending around the opening area, and a middle area between the opening area and the display area; a light-emitting element in the display area, the light-emitting element including a pixel electrode, an opposite electrode, and a functional layer between the pixel electrode and the opposite electrode; a first separator in the middle area; a second separator between the first separator and the opening area; a first groove between the first separator and the second separator; and a first protective layer between the substrate and the first groove.

Claims (25)

1 . A display device comprising:

a substrate having an opening area, a display area at least partially extending around the opening area, and a middle area between the opening area and the display area;

a light-emitting element in the display area, the light-emitting element comprising a pixel electrode, an opposite electrode, and a functional layer between the pixel electrode and the opposite electrode;

a first separator in the middle area;

a second separator between the first separator and the opening area;

a first groove between the first separator and the second separator; and

a first protective layer between the substrate and the first groove, an inner edge of the first protective layer being covered by the second separator and an outer edge of the first protective layer being covered by the first separator.

2 . The display device of claim 1 , wherein the first separator comprises a first organic pattern layer, a second organic pattern layer, and a third organic pattern layer sequentially stacked in this order, and

wherein a width of an upper portion of the first organic pattern layer is greater than a width of a lower portion of the first organic pattern layer.

3 . The display device of claim 2 , wherein a width of the second organic pattern layer is greater than a width of the first organic pattern layer.

4 . The display device of claim 1 , wherein the functional layer extends from the display area to the middle area, and

wherein the functional layer is disconnected at the first separator and the second separator.

5 . The display device of claim 1 , wherein the opposite electrode extends from the display area to the middle area, and

wherein the opposite electrode is disconnected at the first separator and the second separator.

6 . The display device of claim 1 , further comprising:

a first dam between the display area and the first separator;

a second groove between the first dam and the first separator; and

a second protective layer between the substrate and the second groove.

7 . The display device of claim 6 , further comprising:

a third separator between the second separator and the opening area;

a third groove between the second separator and the third separator; and

a third protective layer between the substrate and the third groove.

8 . The display device of claim 7 , further comprising:

a second dam between the third separator and the opening area; and

a crack dam between the second dam and the opening area.
