Abstract

A display device, and a method and apparatus for manufacturing the display device, are provided. The display device includes a cover window including a curved portion, and a display panel smaller in at least one of length or width than the cover window and laminated on a flat portion of the cover window.

First claim

What is claimed is:

1. A display device comprising:
a cover window comprising a curved portion and a flat portion; and
a display panel smaller in at least one of length or width than the cover window and laminated on the flat portion of the cover window, the display panel comprising:
a substrate;
a light-emitting unit on the substrate and comprising an organic light emitting device; and
a thin film on the light-emitting unit, the thin film comprising an organic layer and an inorganic layer,

wherein the display panel is laminated entirely on the flat portion, and
wherein the cover window is formed from a single piece.

2. The display device of claim 1 , further comprising an adhesive layer between the display panel and the cover window.

3. The display device of claim 1 , wherein the display panel is flexible.

4. A display device comprising:
a cover window comprising a curved portion and a flat portion; and
a display panel smaller in at least one of length or width than the cover window and laminated on the flat portion of the cover window, the display panel comprising:
a substrate;
a light-emitting unit on the substrate and comprising an organic light emitting device; and
a thin film on the light-emitting unit, the thin film comprising an organic layer and an inorganic layer,

wherein the curved portion comprises a plurality of curved portions, and
wherein the cover window is formed from a single piece.

5. The display device of claim 4 , further comprising an adhesive layer between the display panel and the cover window.

6. The display device of claim 4 , wherein the display panel is flexible.

7. The display device of claim 4 , wherein the display panel is laminated entirely on the flat portion.

8. A display device comprising:
a cover window comprising a curved portion and a flat portion; and
a display panel comprising:
a substrate;
a light-emitting unit on the substrate and comprising an organic light emitting device; and
a thin film on the light-emitting unit, the thin film comprising an organic layer and an inorganic layer,

wherein the display panel is smaller in at least one of length or width than the cover window and laminated on the flat portion of the cover window, and defines:
a first display panel portion laminated on the flat portion; and
second display panel portion extending in a curved shape from the first display panel portion and laminated on the curved portion, and

wherein the cover window is formed from a single piece.

9. The display device of claim 8 , further comprising an adhesive layer between the first display panel portion and the cover window, and between the second display panel portion and the cover window.

10. The display device of claim 8 , wherein the display panel is flexible.

11. The display device of claim 8 , wherein the display panel is laminated entirely on the flat portion.

12. The display device of claim 8 , wherein the curved portion comprises a plurality of curved portions.

13. A display device comprising:
a cover window comprising a curved portion and a flat portion, the cover window having a uniform thickness in its entirety and being formed from a single piece; and
a display panel smaller in at least one of length or width than the cover window and disposed on the flat portion of the cover window, the display panel comprising:
a substrate;
a light-emitting unit on the substrate and comprising an organic light emitting device; and
a thin film on the light-emitting unit, the thin film comprising an organic layer and an inorganic layer.

14. The display device of claim 13 , further comprising an adhesive layer between the display panel and the cover window.

15. The display device of claim 13 , wherein the display panel is disposed entirely on the flat portion.

16. The display device of claim 13 , wherein the curved portion comprises a plurality of curved portions.

17. The display device of claim 13 , wherein the display panel comprises:
a first display panel portion disposed on the flat portion; and
a second display panel portion extending in a curved shape from the first display panel portion and disposed on the curved portion.

18. The display device of claim 17 , further comprising an adhesive layer between the first display panel portion and the cover window, and between the second display panel portion and the cover window.

19. The display device of claim 13 , wherein the display panel is flexible.

20. The display device of claim 1 , wherein the display device further comprises a halogenated metal layer between the light-emitting unit and the inorganic layer.
