Abstract

A display device includes first and second guide plates facing each other, a pair of first and second guide rails disposed in the first and second guide plates, a first supporting plate disposed between the first guide rails and of the first and second guide plates, the first supporting plate having opposite end portions fixed to a first position of the first and second guide plates, a second supporting plate having opposite end portions coupled to the pair of first guide rails, a third supporting plate having opposite end portions coupled to the pair of second guide rails, and a display panel supported by at least one of the first to third supporting plates. The pair of first guide rails extends from the first position to a second position. The pair of second guide rails extends from the first position to a third position.

First claim

What is claimed is:

1. A display device, comprising:
first and second guide plates facing each other;
a pair of first guide rails disposed in the first and second guide plates, respectively;
a pair of second guide rails disposed in the first and second guide plates, respectively;
a first supporting plate disposed between the first guide rails and the second guide rails at the first guide plate and the first and second guide rails at the second guide plate, wherein the first supporting plate has opposite end portions fixed to a first position of the first and second guide plates;
a second supporting plate configured to have opposite end portions coupled to the pair of first guide rails;
a third supporting plate configured to have opposite end portions coupled to the pair of second guide rails; and
a display panel supported by at least one of the first to third supporting plates,
wherein the pair of first guide rails are respectively formed to extend from the first position to a second position, and
the pair of second guide rails are respectively formed to extend from the first position to a third position, wherein the first position is disposed between the second position and the third position.

2. The display device of claim 1 , wherein portions of the pair of first guide rails and the second guide rails are overlapped with each other.

3. The display device of claim 2 , wherein each of the pair of first guide rails includes:
a first flat portion positioned at the first position;
a second flat portion positioned at the second position; and
a first connector configured to connect the first flat portion with the second flat portion.

4. The display device of claim 3 , wherein each of the pair of second guide rails includes:
a third flat portion positioned at the first position;
a fourth flat portion positioned at the third position; and
a second connector configured to connect the third flat portion with the fourth flat portion.

5. The display device of claim 4 , wherein portions of the second flat portion and the fourth flat portion are overlapped with each other.

6. The display device of claim 4 , wherein the first supporting plate is disposed between the second flat portion and the fourth flat portion.

7. The display device of claim 6 , wherein the first flat portion and the third flat portion are disposed at opposite sides of the first supporting plate.

8. The display device of claim 4 , further comprising:
a first panel accommodating portion fixed to a side of the second supporting plate, to accommodate a first end portion of the display panel.

9. The display device of claim 8 , wherein a first rolling bar is disposed in the first panel accommodating portion, wherein the first rolling bar has an external circumferential surface to which the first end portion of the display panel is coupled, and the first rolling bar is configured to roll the first end portion of the display panel.

10. The display device of claim 8 , further comprising:
a second panel accommodating portion fixed to a side of the third supporting plate to accommodate a second end portion of the display panel.

11. The display device of claim 10 , wherein a second rolling bar is disposed in the second panel accommodating portion, wherein the second rolling bar has an external circumferential surface to which the second end portion of the display panel is coupled, and the second rolling bar is configured to roll the second end portion of the display panel.

12. The display device of claim 4 , further comprising:
a first magnetic member disposed below the first flat portion, wherein opposite end portions of the first magnetic member are respectively fixed to the first and second guide plates.

13. The display device of claim 12 , further comprising:
a second magnetic member disposed below the third flat portion, wherein opposite end portions of the second magnetic member are respectively fixed to the first and second guide plates.

14. The display device of claim 1 , wherein each of two opposite end portions of the second supporting plate includes a first sliding portion coupled to one of the first guide rails, wherein the first sliding portion is configured to slide along the one of the first guide rails.

15. The display device of claim 14 , wherein a first accommodating groove of the first sliding portion accommodates the one of the first guide rails.

16. The display device of claim 14 , wherein each of two opposite end portions of the third supporting plate includes a second sliding portion coupled to one of the second guide rails, wherein the second sliding portion is configured to slide along the one of the second guide rails.

17. The display device of claim 16 , wherein a second accommodating groove of the second sliding portion accommodates the second guide rail.

18. The display device of claim 16 , further comprising:
a belt configured to surround the first guide rail and the second guide rail of the first guide plate, and rotate to move the first and second sliding portions, disposed adjacent to the first guide plate.

19. The display device of claim 18 , further comprising:
at least one rotation bar having opposite end portions coupled to the first and second guide plates, wherein the at least one rotation bar is coupled to the belt and is configured to rotate the belt.

20. The display device of claim 19 , further comprising:
a motor coupled to the at least one rotation bar and configured to rotate the at least one rotation bar.

21. The display device of claim 1 , wherein each of the first to third supporting plates has a plate-like shape having a quadrangular plane.

22. The display device of claim 1 , wherein the pair of second guide rails is separated from the pair of first guide rails.

23. The display device of claim 1 , wherein opposite end portions of the second supporting plate are slidably coupled to the pair of first guide rails, respectively.

24. The display device of claim 1 , wherein opposite end portions of the third supporting plate are slidably coupled to the pair of second guide rails, respectively.
