2. The display device of claim 1 , wherein the layers have an opening at the bending region of the display device, and expose at least a portion of a lower surface of the display panel.

3. The display device of claim 1 , wherein the opening is formed by laser irradiation.

4. The display device of claim 1 , wherein a neutral plane at the bending region of the display device is formed between an upper surface of the display panel and a lower surface of the display panel.

5. The display device of claim 1 , wherein the top member includes at least one selected from a polarizer, a touch screen panel or a plastic window.

6. The display device of claim 1 , wherein the bottom member includes bottom films.

7. The display device of claim 1 , wherein the display panel includes:
a first substrate on the bottom member;
a light emitting structure on the first substrate; and
a second substrate on the light emitting structure.

8. The display device of claim 7 , wherein the first substrate has flexible materials.

9. The display device of claim 7 , wherein the second substrate has a stack structure where at least one inorganic layer and at least one organic layer are alternately stacked.

10. A display device, comprising:
a display panel;
a top member on the display panel, the top member having an opening at a bending region of the display device; and
a bottom member under the display panel, the bottom member including a plurality of layers wherein at least one of the layers has an opening at the bending region of the display device.

11. The display device of claim 10 , wherein the layers have an opening at the bending region of the display device, and expose at least a portion of a lower surface of the display panel.

12. The display device of claim 11 , wherein the openings are formed by laser irradiation.

13. The display device of claim 10 , wherein a neutral plane at the bending region of the display device is formed between an upper surface of the display panel and a lower surface of the display panel.

14. The display device of claim 10 , wherein the top member includes at least one selected from a polarizer, a touch screen panel or a plastic window, and the bottom member includes bottom films.

15. The display device of claim 10 , wherein the display panel includes:
a first substrate on the bottom member;
a light emitting structure on the first substrate; and
a second substrate on the light emitting structure,
wherein the first substrate has flexible materials, and
wherein the second substrate has a stack structure where at least one inorganic layer and at least one organic layer are alternately stacked.

16. A display device, comprising:
a display panel having a display region and a peripheral region surrounding the display region;
a top member in the display region on the display panel; and
a bottom member under the display panel, the bottom member including a plurality of layers wherein at least one of the layers has a groove at the bending region of the display device.

17. The display device of claim 16 , wherein the layers have an opening at the bending region of the display device, and expose at least a portion of a lower surface of the display panel.

18. The display device of claim 17 , wherein the groove and the opening are formed by laser irradiation.

19. The display device of claim 16 , wherein a neutral plane at the bending region of the display device is formed between an upper surface of the display panel and a lower surface of the display panel.

20. The display device of claim 16 , wherein the top member includes at least one selected from a polarizer, a touch screen panel or a plastic window, and wherein the bottom member includes bottom films.

21. The display device of claim 16 , wherein the display panel includes:
a first substrate on the bottom member;
a light emitting structure on the first substrate; and
a second substrate on the light emitting structure,
wherein the first substrate has flexible materials, and
wherein the second substrate has a stack structure where at least one inorganic layer and at least one organic layer are alternately stacked.

22. A display device, comprising:
a display panel having a display region and a peripheral region surrounding the display region;
a top member on the display panel, the top member exposing the peripheral region of the display panel; and
a bottom member under the display panel, the bottom member including a plurality of layers wherein at least one of the layers has a groove at the bending region of the display device.

23. The display device of claim 22 , wherein the layers have an opening at the bending region of the display device, and expose at least a portion of a lower surface of the display panel.

24. The display device of claim 23 , wherein the groove and the opening are formed by laser irradiation.

25. The display device of claim 22 , wherein a neutral plane at the bending region of the display device is formed between an upper surface of the display panel and a lower surface of the display panel.

26. The display device of claim 22 , wherein the top member includes at least one selected from a polarizer, a touch screen panel or a plastic window, and wherein the bottom member includes bottom films.

27. The display device of claim 22 , wherein the display panel includes:
a first substrate on the bottom member;
a light emitting structure on the first substrate; and
a second substrate on the light emitting structure,
wherein the first substrate has flexible materials, and
wherein the second substrate has a stack structure where at least one inorganic layer and at least one organic layer are alternately stacked.

28. A display device, comprising:
a display panel having a display region and a peripheral region surrounding the display region;
a top member in the display region on the display panel; and
a bottom member under the display panel, the bottom member having an opening where at least a portion of a lower surface of the display panel is exposed,
wherein the opening is located at a bending region of the display device.
