Abstract

A display device includes a cover window including a curved portion, and a panel member laminated on the cover window. A method of manufacturing a display device includes mounting a cover window including a curved portion on a first jig including a curved portion, mounting a panel member on a second jig that conforms to a surface of the first jig, and laminating the cover window to the panel member by moving a first one of the first jig or the second jig to a first other one of the first jig or the second jig. An apparatus for manufacturing a display device includes a first jig including a mount surface that is partially curved to conform to a surface of a cover window, a second jig including a surface conforming to the mount surface and configured to contact a panel member, and a driving unit.

First claim

What is claimed is:

1. A display device comprising:
a cover window comprising a curved portion; and
a panel member laminated on the cover window,
wherein the panel member comprises:
a display panel; and
an adhesive layer on the display panel and attaching the display panel to the cover window,
wherein an end of the panel member is at a different height from a corresponding end of the cover window,
wherein the end of the panel member and the corresponding end of the cover window are not arranged to overlap with each other, and
wherein the end of the panel member is on a surface of the curved portion of the cover window, and is arranged to cover a portion and expose another portion of the surface of the curved portion of the cover window,
wherein the panel member has a first surface and a second surface facing away from the first surface, and an end surface at the end of the panel member connecting the first surface and the second surface,
the cover window has a first surface and a second surface facing away from the first surface, and an end surface at the corresponding end of the cover window connecting the first surface and the second surface, and
the adhesive layer is disposed between the first surface of the panel member and the second surface of the cover window.

2. The display device of claim 1 , wherein the panel member is smaller in at least one of a length or a width than the cover window.

3. The display device of claim 1 , wherein the cover window further comprises a flat portion extending from the curved portion.

4. The display device of claim 3 , wherein the curved portion comprises a plurality of curved portions.

5. The display device of claim 3 , wherein the panel member comprises:
a first panel portion laminated on the flat portion; and
a second panel portion extending in a curved shape from the first panel portion and laminated on the curved portion.

6. The display device of claim 1 , wherein the cover window has a curved surface having a curvature radius.

7. The display device of claim 1 , wherein a curvature radius of a portion of the cover window is different from a curvature radius of another-portion of the cover window.

8. The display device of claim 1 , wherein the panel member is formed on a recessed second surface of the cover window or a protruding second surface of the cover window.

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

10. A display device comprising:
a cover window comprising a central portion that is flat, one end that is connected to the central portion and has a first curved surface, and an other end that is connected to the central portion and has a second curved surface; and
a panel member that is provided on an outer surface of the central portion and the ends of the cover window, the panel member being partially curved,
wherein an end of the panel member is at a different height from a corresponding end of the cover window,
wherein the end of the panel member and the corresponding end of the cover window are not arranged to overlap with each other,
wherein the end of the panel member is on a surface of the second curved surface of the cover window, and is arranged to cover a portion and expose another portion of the surface of the second curved surface of the cover window,
wherein the panel member has a first surface and a second surface facing away from the first surface, and an end surface at the end of the panel member connecting the first surface and the second surface,
the cover window has a first surface and a second surface facing away from the first surface, and an end surface at the corresponding end of the cover window connecting the first surface and the second surface, and
a first adhesive layer is disposed between the first surface of the panel member and the second surface of the cover window.

11. The display device of claim 10 , wherein the panel member is attached to the second surface of the cover window that is recessed or to the second surface of the cover window that protrudes.

12. The display device of claim 10 , wherein a size of the panel member is different from a size of the cover window.

13. The display device of claim 12 , wherein the size of the panel member is less than the size of the cover window.

14. The display device of claim 12 , wherein both ends of the panel member are disposed on at least one selected from the first curved surface and the second curved surface of the cover window.

15. The display device of claim 10 , wherein the panel member comprises:
the first adhesive layer that is provided on the cover window;
a touch panel that is provided on the first adhesive layer;
a second adhesive layer that is provided on the touch panel; and
a display panel that is provided on the second adhesive layer.

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

17. The display device of claim 10 , wherein at least one selected from the first curved surface and the second curved surface is a curved surface having at least one radius of curvature.

18. The display device of claim 10 , wherein the panel member comprise a display panel,
wherein the display panel comprises:
a first substrate;
a plurality of organic light emitting diodes on the first substrate; and

an encapsulation unit on the plurality of organic light emitting diodes for encapsulating the plurality of organic light emitting diodes.
