Abstract

A display device includes: a display panel having a first curved portion and a second curved portion; a window on one surface of the display panel; and a circuit board connected to the display panel, wherein the display panel includes a front display portion and a side display portion which are separated by the first curved portion, and wherein the second curved portion includes a pad portion connected to the circuit board.

Claims

1. A display device comprising:

a display panel comprising;

a front display portion and a side display portion, the front display portion and the side display portion being configured to emit light for displaying an image;

a curved display portion between the front display portion and the side display portion; and

a pad portion bent at an edge of the side display portion and facing the front display portion;

a window on one surface of the display panel, the window comprising;

a front portion on the front display portion;

a side portion on the side display portion; and

a curved portion between the front portion and the side portion; and

a circuit board connected to the pad portion of the display panel.

2. The display device of claim 1, wherein the circuit board is on a surface of the pad portion.

3. The display device of claim 1, wherein the pad portion is between the front display portion and the circuit board.

4. The display device of claim 1, further comprising a printed circuit board connected to the circuit board and on another surface of the display panel.

5. The display device of claim 1, further comprising a printed circuit board on one surface of the circuit board,

wherein the circuit board is on another surface of the display panel.

6. The display device of claim 1,

wherein the circuit board directly contacts an end portion of the window.

7. The display device of claim 1, wherein a housing on the window has at least an aperture, and

the side display portion is exposed through the aperture.

8. The display device of claim 7, further comprising a transparent material in the aperture.

9. The display device of claim 7, further comprising a transparent button member and a biasing member to apply a pressure to the transparent button member and located in the aperture.

10. The display device of claim 9, wherein the transparent button member comprises a lens.

22. The display device of claim 1, wherein the circuit board has a slope portion.

23. The display device of claim 22, wherein the slope portion of the circuit board is inclined upward from an end of the circuit board that is connected to the pad portion.

11. A display device comprising:

a display panel comprising;

a front display portion and a pair of side display portions, the front display portion and the side display portions being configured to emit light to display an image;

a pair of curved display portions, each located between the front display portion and a corresponding one of the pair of side display portions; and

a pair of pad portions bent at each edge of the pair of side display portions, respectively, and facing the front display portion;

a window on one surface of the display panel, the window comprising;

a front portion on the front display portion;

a pair of side portions on the pair of side display portions, respectively; and

a pair of curved portions, each located between the front portion and a corresponding one of the pair of side portions; and

a pair of circuit boards connected to respective ones of the pad portions of the display panel.

12. The display device of claim 11, wherein the circuit boards are on respective ones of surfaces of the pair of pad portions.

13. The display device of claim 11, wherein each of the pair of pad portions is disposed between the front display portion and a corresponding one of the circuit boards.

14. The display device of claim 11, further comprising a printed circuit board connected to the circuit boards and on another surface of the display panel.

15. The display device of claim 11, further comprising a printed circuit board on a surface of one of the pair of circuit boards,

wherein the circuit boards are on another surface of the display panel.

16. The display device of claim 11,

wherein the circuit boards directly contact respective end portions of the window.

17. The display device of claim 11, wherein a housing on the window has at least an aperture, and

the side display portion is exposed through the aperture.

18. The display device of claim 17, further comprising a transparent material located in the aperture.

19. The display device of claim 17, further comprising a transparent button member and a biasing member to apply a pressure to the transparent button member and located in the aperture.

20. The display device of claim 19, wherein the transparent button member comprises a lens.

24. The display device of claim 11, wherein each of the circuit boards has a slope portion.

25. The display device of claim 24, wherein the slope portion of the circuit boards is inclined upward from an end of a corresponding one of the circuit boards that is connected to a corresponding one of the pad portions.

21. A display device comprising:

a display panel comprising;

a front display portion and a side display portion, the front display portion and the side display portion comprising a plurality of pixels for displaying an image;

a curved display portion between the front display portion and the side display portion; and

a pad portion bent at an edge of the side display portion and facing the front display portion;

a window on one surface of the display panel, the window comprising;

a front portion on the front display portion;

a side portion on the side display portion; and

a curved portion between the front portion and the side portion; and

a circuit board connected to the pad portion of the display panel.

26. The display device of claim 21, wherein the circuit board has a slope portion.

27. The display device of claim 26, wherein the slope portion of the circuit board is inclined upward from an end of the circuit board that is connected to the pad portion.
