Abstract

Provided is a foldable display apparatus, whereby an arrangement line connecting plurality of spacers via a virtual straight line is not arranged in parallel to a folding axis.

Claims (27)

1. A foldable display apparatus comprising:

a panel body comprising a folding portion which is foldable with respect to a folding axis, a plurality of pixels arranged in the panel body, and a plurality of spacers arranged between respective ones of the plurality of pixels of the panel body,

wherein a first arrangement line connecting the plurality of spacers in the folding portion via a virtual straight line is not parallel to the folding axis.

2. The foldable display apparatus of claim 1 , wherein a number of the plurality of spacers arranged in a line parallel to the folding axis in the folding portion is equal to or less than two.

3. The foldable display apparatus of claim 1 , wherein a second arrangement line connecting the plurality of pixels in the folding portion via a virtual straight line is not parallel to the first arrangement line.

4. The foldable display apparatus of claim 3 , wherein the plurality of pixels and the two or more spacers are arranged in a plurality-to-one correspondence.

5. The foldable display apparatus of claim 3 , wherein the plurality of pixels comprise a pixel-defining layer defining an emission area, and a thin film encapsulation layer covering and protecting the emission area, and

the two or more spacers are arranged between the pixel-defining layer and the thin film encapsulation layer.

6. The foldable display apparatus of claim 5 , wherein the thin film encapsulation layer comprises a multi-layer in which an organic layer and an inorganic layer are stacked.

7. The foldable display apparatus of claim 5 , wherein the thin film encapsulation layer comprises a single inorganic layer.

8. The foldable display apparatus of claim 3 , wherein the first arrangement line and the second arrangement line maintain the same arrangement pattern in areas except for the folding portion of the panel body.

9. The foldable display apparatus of claim 3 , wherein the first arrangement line and the second arrangement line have a different arrangement pattern in areas except for the folding portion of the panel body.

10. The foldable display apparatus of claim 1 , wherein the plurality of spacers are configured to mount a deposition mask.

11. A method of manufacturing a foldable display apparatus, the method comprising:

forming a plurality of pixels in a panel body comprising a folding portion foldable with respect to a folding axis; and

forming a plurality of spacers between respective ones of the plurality of pixels of the panel body,

wherein a first arrangement line connecting the plurality of spacers in the folding portion via a virtual straight line is not parallel to the folding axis.

12. The method of claim 11 , wherein a number of the two or more spacers arranged in a line parallel to the folding axis in the folding portion is equal to or less than two.

13. The method of claim 11 , wherein a second arrangement line connecting the plurality of pixels in the folding portion via a virtual straight line is not parallel to the first arrangement line.

14. The method of claim 13 , wherein the plurality of pixels and the plurality of spacers are arranged in a plurality-to-one correspondence.

15. The method of claim 13 , wherein the plurality of pixels comprise a pixel-defining layer defining an emission area, and a thin film encapsulation layer covering and protecting the emission area, and

the plurality of spacers are arranged between the pixel-defining layer and the thin film encapsulation layer.

16. The method of claim 15 , wherein the thin film encapsulation layer comprises a multi-layer in which an organic layer and an inorganic layer are stacked.

17. The method of claim 15 , wherein the thin film encapsulation layer comprises a single inorganic layer.

18. The method of claim 13 , wherein the first arrangement line and the second arrangement line maintain the same arrangement pattern in areas except for the folding portion of the panel body.

19. The method of claim 13 , wherein the first arrangement line and the second arrangement line have a different arrangement pattern in areas except for the folding portion of the panel body.

20. The method of claim 11 , wherein the two or more spacers are configured to mount a deposition mask.
