Abstract

Provided is a display apparatus that is bendable. The display apparatus includes: a substrate including a display region that includes a plurality of light-emitting devices and an edge region that surrounds the display region; and a thin-film encapsulation layer on the display region and the edge region of the substrate. The thin-film encapsulation layer includes a plurality of inorganic films and at least one organic film disposed between the plurality of the inorganic films. At least one of the plurality of the inorganic films of the thin-film encapsulation layer includes inorganic patterns.

Claims (30)

1. A display apparatus, comprising:

a substrate comprising a display region that comprises a plurality of light-emitting devices, and an edge region that surrounds the display region; and

a thin-film encapsulation layer disposed on the display region and the edge region of the substrate, wherein the thin-film encapsulation layer comprises a plurality of inorganic films and at least one organic film disposed between the plurality of inorganic films, at least one of the plurality of the inorganic films including inorganic patterns that are spatially separated from each other.

2. The display apparatus of claim 1 , wherein a portion of the display apparatus, on which the inorganic patterns are disposed, is bendable.

3. The display apparatus of claim 1 , wherein the inorganic patterns are located on the edge region.

4. The display apparatus of claim 1 , wherein the substrate extends in first and second directions that are perpendicular to each other, the inorganic patterns comprising:

first inorganic patterns, the display region being disposed between the first inorganic patterns in the first direction; and

second inorganic patterns, the display region being disposed between the second inorganic patterns in the second direction, the first inorganic patterns being arranged in line patterns extending in the second direction and spatially separated from each other in the first direction, the second inorganic patterns being arranged in line patterns extending in the first direction and spatially separated from each other in the second direction.

5. The display apparatus of claim 1 , wherein the inorganic patterns are arranged in tile patterns.

6. The display apparatus of claim 1 , wherein the plurality of light-emitting devices are organic light-emitting devices.

7. The display apparatus of claim 1 , wherein the inorganic patterns are partially formed on portions of the edge region, and the display region is disposed between the portions of the edge regions.

8. The display apparatus of claim 7 , wherein the inorganic patterns are arranged in line patterns extending in a first direction and spatially separated from each other in a second direction perpendicular to the first direction, and the display region is disposed between the portions of the edge regions in the second direction.

9. The display apparatus of claim 1 , further comprising an organic material filling a space formed between the inorganic patterns spatially separated from each other.

10. The display apparatus of claim 9 , wherein the organic material is the same as a material of the at least one organic film.

11. The display apparatus of claim 9 , wherein the organic material is different from a material of the at least one organic film.

12. A display apparatus comprising:

a substrate comprising a display region and an edge region;

a plurality of light-emitting devices formed on the display region of the substrate;

a lower inorganic film disposed on the display region and the edge region to cover the plurality of light-emitting devices;

an organic film disposed on the lower inorganic film to cover the display region; and

an upper inorganic film disposed on the lower inorganic film and the organic film to cover the organic film, wherein at least one of the lower inorganic film and the upper inorganic film comprises inorganic patterns formed on the edge region, the inorganic patterns spatially separated from each other.

13. The display apparatus of claim 12 , wherein the lower inorganic film comprises the inorganic patterns spatially separated from each other, a portion of the edge region is exposed through a gap formed between the inorganic patterns of the lower inorganic film, and the organic film fills the gap formed between the inorganic patterns of the lower inorganic film, the organic film covering the exposed portion of the edge region.

14. The display apparatus of claim 12 , wherein the lower inorganic film comprises the inorganic patterns spatially separated from each other, a portion of the edge region being exposed through a gap formed between the inorganic patterns of the lower inorganic film,

the display apparatus further comprises an organic material filling the gap formed between the inorganic patterns of the lower inorganic film, the organic material covering the exposed portion of the edge region, and

the upper inorganic film completely covers the inorganic patterns and the organic material.

15. The display apparatus of claim 12 , wherein the edge region is bendable.

16. The display apparatus of claim 12 , wherein a portion of the edge region is exposed through a gap formed between the inorganic patterns, and the inorganic patterns comprise lower inorganic patterns and upper inorganic patterns formed on the lower inorganic patterns, the lower inorganic film comprising the lower inorganic patterns, the upper inorganic film comprising the upper inorganic patterns.

17. The display apparatus of claim 16 , further comprising an organic material filling the gap formed between the inorganic patterns and covering the exposed portion of the edge region.

18. The display apparatus of claim 12 , wherein the lower inorganic film continuously covers the edge region, and the upper inorganic film comprises the inorganic patterns spatially separated from each other, a portion of the lower inorganic film being exposed through a gap formed between the inorganic patterns of the upper inorganic film.

19. The display apparatus of claim 18 , further comprising an organic material filling the gap formed between the inorganic patterns of the upper inorganic film, and covering the exposed portion of the lower inorganic film.
