Abstract

An organic light-emitting display apparatus including a substrate having a display area and a peripheral area outside the display area, a first insulating layer arranged over the substrate throughout the display area and the peripheral area, the first insulating layer including a first opening disposed in the peripheral area, a first electrode arranged over the first insulating layer in the display area, a pixel defining film arranged over the first insulating layer, the pixel defining film including a second opening exposing a portion of the first electrode and a third opening formed at the location of the first opening to form a common opening, an intermediate layer arranged over the first electrode, and a second electrode covering the intermediate layer, the pixel defining film, at least a portion of the third opening, and at least a portion of the first opening.

Claims (51)

1. An organic light-emitting display apparatus, comprising:

a substrate having a display area and a peripheral area outside the display area;

a first insulating layer arranged over the substrate throughout the display area and the peripheral area, the first insulating layer comprising a first opening disposed in the peripheral area;

a first electrode arranged over the first insulating layer in the display area;

a pixel defining film arranged over the first insulating layer, the pixel defining film comprising a second opening exposing a portion of the first electrode, and a third opening formed at the location of the first opening to form a common opening;

an intermediate layer arranged over the first electrode; and

a second electrode covering the intermediate layer, the pixel defining film, at least a portion of the third opening, and at least a portion of the first opening.

2. The organic light-emitting display apparatus of claim 1 , further comprising a conductive layer arranged over the first insulating layer in the peripheral area, wherein the conductive layer covers the first opening.

3. The organic light-emitting display apparatus of claim 2 , wherein

the pixel defining film comprises a plurality of fourth openings over at least a portion of the conductive layer.

4. The organic light-emitting display apparatus of claim 3 , wherein

the second electrode contacts the conductive layer through the plurality of fourth openings.

5. The organic light-emitting display apparatus of claim 3 , wherein

the pixel defining film is divided into a plurality of areas by the plurality of fourth openings.

6. The organic light-emitting display apparatus of claim 2 , wherein

the conductive layer comprises a plurality of fifth openings disposed around the first opening.

7. The organic light-emitting display apparatus of claim 2 , wherein

the second electrode directly contacts the conductive layer disposed in the first opening.

8. The organic light-emitting display apparatus of claim 1 , wherein

a width of the third opening is greater than a width of the first opening.

9. The organic light-emitting display apparatus of claim 1 , further comprising a second insulating layer arranged below the first insulating layer,

wherein the second insulating layer comprises an inorganic material and the first opening extends to the second insulating layer.

10. The organic light-emitting display apparatus of claim 1 , wherein

the second electrode completely covers the third opening and the first opening.

11. The organic light-emitting display apparatus of claim 1 , wherein

the first opening surrounds the display area.

12. The organic light-emitting display apparatus of claim 11 , wherein

the first insulating layer is divided into a first area and a second area by the first opening.

13. The organic light-emitting display apparatus of claim 12 , wherein

the pixel defining film is divided into at least two areas by the third opening.

14. The organic light-emitting display apparatus of claim 11 , wherein

the first opening forms a closed loop, and

the second electrode completely covers the first opening.

15. The organic light-emitting display apparatus of claim 14 , wherein

an edge of the second electrode is outside the first opening with respect to the display area, and

a distance between the edge of the second electrode and the first opening in an area corresponding to a corner of the display area is less than a distance between the edge of the second electrode and the first opening in an area except for the area corresponding to the corner of the display area.

16. The organic light-emitting display apparatus of claim 14 , wherein

the closed loop comprises an area recessed toward the display area in an area corresponding to a corner of the display area.

17. The organic light-emitting display apparatus of claim 14 , wherein

the second electrode comprises an area protruding in a direction away from the display area in an area corresponding to a corner of the display area.

18. The organic light-emitting display apparatus of claim 1 further comprising a capping layer arranged over the second electrode and covering the first opening.

19. The organic light-emitting display apparatus of claim 18 , wherein

the capping layer is separated from the pixel defining film in the third opening by the second electrode.

20. The organic light-emitting display apparatus of claim 18 , wherein

each of the first insulating layer, the pixel defining film, and the capping layer comprises an organic material.

21. The organic light-emitting display apparatus of claim 18 , further comprising an encapsulating layer arranged over the capping layer,

wherein the encapsulating layer comprises at least one inorganic layer and at least one organic layer.

22. The organic light-emitting display apparatus of claim 1 , wherein

the first insulating layer comprises at least two first openings.

23. The organic light-emitting display apparatus of claim 22 , wherein

the first insulating layer comprises a first area, a second area, and a third area separated from one another by the at least two first openings.
