Abstract

A display apparatus includes a base layer including device counterparts and bridges, the bridges being located around the device counterparts and connecting the device counterparts to each other, an inorganic insulating layer located over the base layer and having openings exposing at least a portion of at least one of the bridges, organic layers filling the openings, wires located over the organic layers, display devices located over the device counterparts, and encapsulation films each of which has a form of an island to correspond to a corresponding one of the device counterparts, each of the encapsulation films including a first inorganic encapsulation film covering a corresponding one of the display devices, an organic encapsulation film located over the first inorganic encapsulation film, and a second inorganic encapsulation film covering the organic encapsulation film and contacting the first inorganic encapsulation film outside of the organic encapsulation film.

First claim

What is claimed is:

1. A display apparatus comprising:
a base layer comprising device counterparts and bridges, the bridges being located around the device counterparts and connecting the device counterparts to each other;
an inorganic insulating layer located over the base layer and having openings exposing at least a portion of at least one of the bridges;
organic layers filling the openings;
wires located over the organic layers;
display devices located over the device counterparts; and
encapsulation films each of which has a form of an island to correspond to a corresponding one of the device counterparts, each of the encapsulation films comprising:
a first inorganic encapsulation film covering a corresponding one of the display devices;
an organic encapsulation film located over the first inorganic encapsulation film; and
a second inorganic encapsulation film covering the organic encapsulation film and contacting the first inorganic encapsulation film outside of the organic encapsulation film.

2. The display apparatus of claim 1 , wherein at least a portion of the organic encapsulation film has a convex lens shape.

3. The display apparatus of claim 1 , wherein a surface of the first inorganic encapsulation film facing the organic encapsulation film is more hydrophobic than a surface of the second inorganic encapsulation film facing away from the first inorganic encapsulation film.

4. The display apparatus of claim 1 , further comprising a hydrophobic coating layer arranged between the first inorganic encapsulation film and the organic encapsulation film.

5. The display apparatus of claim 1 , wherein each of the device counterparts has a quadrangular shape, and a corresponding one of the bridges is connected to each side of each of the device counterparts.

6. The display apparatus of claim 5 , wherein each of the bridges has a curved portion and the curved portion is adjacent to a corresponding one of the device counterparts.

7. The display apparatus of claim 6 , wherein the curved portion has a uniform radius of curvature.

8. The display apparatus of claim 1 , wherein the base layer further comprises peripheral regions connected to an edge of the device counterparts, and slits formed between the peripheral regions and the bridges.

9. The display apparatus of claim 8 , wherein each of the slits comprises a curved portion.

10. The display apparatus of claim 1 , further comprising thin-film transistors located over the device counterparts and electrically connected to the display devices, wherein the wires comprise a same material as a material comprised in source electrodes and drain electrodes of the thin-film transistors.

11. The display apparatus of claim 1 , wherein the organic layers cover an edge of the inorganic insulating layer.

12. A display apparatus comprising:
a base layer comprising device counterparts and bridges, the bridges being located around the device counterparts and connecting the device counterparts to each other;
an inorganic insulating layer located over the base layer and having openings exposing at least a portion of at least one of the bridges;
organic layers filling the openings;
wires located over the organic layers;
display device sets located over a corresponding one of the device counterparts, wherein each of the display device sets comprises a plurality of display devices; and
encapsulation films each of which has a form of an island to correspond to a corresponding one of the device counterparts, each of the encapsulation films comprising:
a first inorganic encapsulation film covering a corresponding one of the display devices;
an organic encapsulation film located over the first inorganic encapsulation film; and
a second inorganic encapsulation film covering the organic encapsulation film and contacting the first inorganic encapsulation film outside of the organic encapsulation film.

13. The display apparatus of claim 12 , wherein each of the plurality of display devices comprises an organic light-emitting device comprising:
a pixel electrode;
an intermediate layer located over the pixel electrode and comprising an emission layer; and
an opposite electrode located over the intermediate layer, and
wherein in the plurality of display devices comprised in one of the display device sets, opposite electrodes are integrated with one another to form a single opposite electrode having a form of an island corresponding to a corresponding one of the device counterparts.

14. The display apparatus of claim 13 , wherein the opposite electrode is connected to at least one of the wires.

15. The display apparatus of claim 12 , wherein the organic encapsulation film of each of the encapsulation films corresponds to corresponding one of the display device sets.
