Abstract

A display device includes a flexible display panel for displaying an image, a flexible functional plate on the flexible display panel, and a thermosetting resin layer between the flexible display panel and the flexible functional plate, wherein the thermosetting resin layer is cured while the flexible display panel and the flexible functional plate are bent.

Claims

1. A display device comprising:

a flexible display panel for displaying an image;

a flexible functional plate on the flexible display panel; and

a thermosetting resin layer between the flexible display panel and the flexible functional plate,

wherein the thermosetting resin layer is cured while the flexible display panel and the flexible functional plate are bent.

2. The display device of claim 1, wherein the flexible functional plate is at least one selected from the group consisting of a polarizing plate, a touch screen panel, and a protection window.

3. The display device of claim 2, further comprising:

one or more additional flexible functional plates on the flexible display panel; and

an additional thermosetting resin layer between the flexible display panel and the one or more additional flexible functional plate.

4. The display device of claim 3, wherein the thermosetting resin layer and the additional thermosetting resin layer are contracted while being cured.

5. The display device of claim 4, wherein the thermosetting resin layer is at an inner side of a direction to which the flexible display panel and the flexible functional plate are curved, wherein the additional thermosetting resin layer is at an outer side of the direction, and wherein the thermosetting resin layer is further contracted than the additional thermosetting resin layer.

6. The display device of claim 1, wherein the thermosetting resin layer bonds the flexible display panel to the flexible functional plate.

7. The display device of claim 1, wherein the thermosetting resin layer provides a reaction force for opposing tension generated from bending the flexible display panel and the flexible functional plate.

8. A manufacturing method of a display device, the method comprising:

preparing a flexible display panel configured to display an image;

placing a thermosetting resin layer on the flexible display panel;

placing a flexible functional plate on the thermosetting resin layer;

bending the flexible display panel and the flexible functional plate with the thermosetting resin layer therebetween; and

curing the thermosetting resin layer while bending the flexible display panel and the flexible functional plate.

9. The manufacturing method of the display device of claim 8, wherein the flexible functional plate is at least one selected from the group consisting of a polarizing plate, a touch screen panel, and a protection window.

10. The manufacturing method of the display device of claim 9, further comprising:

placing an additional flexible functional plate on the flexible display panel; and

placing an additional thermosetting resin layer between the additional flexible functional plate and the flexible functional plate.

11. The manufacturing method of the display device of claim 10, further comprising contracting the thermosetting resin layer and the additional thermosetting resin layer while curing the thermosetting resin layer and the additional thermosetting resin layer.

12. The manufacturing method of the display device of claim 11, wherein the thermosetting resin layer or the additional thermosetting resin layer is located at an inner side of a direction to which the flexible display panel and the flexible functional plate are curved and is further contracted than the other of the thermosetting resin layer or the additional thermosetting resin layer that is located at an outer side of the direction.

13. The manufacturing method of the display device of claim 8, wherein the thermosetting resin bonds the flexible display panel and the flexible functional plate to each other.

14. The manufacturing method of the display device of claim 8, wherein the thermosetting resin layer provides a reaction force for opposing tension generated from the bending the flexible display panel and the flexible functional plate.
