Abstract

A display device includes a display panel having a first display area and a second display area adjacent to the first display area. A first support member is disposed under the display panel and includes a first support layer overlapping the first display area and a second support layer overlapping the second display area. The second support layer has a thickness different from a thickness of the first support layer. A second support member is movable under the first support member from the first display area to the second display area or from the second display area to the first display area.

First claim

What is claimed is:

1. A display device comprising:
a display panel including a first display area and a second display area adjacent to the first display area;
a first support member disposed under the display panel and including a first support layer overlapping the first display area, and a second support layer overlapping the second display area, the second support layer having a thickness different from a thickness of the first support layer, wherein the first and second support layers each including a bottom surface that is positioned on a same plane as each other; and
a second support member disposed under the first support member and movable from being disposed in the first display area to being disposed in the second display area or from being disposed in the second display area to being disposed in the first display area.

2. The display device of claim 1 , wherein the thickness of the first support layer is greater than the thickness of the second support layer.

3. The display device of claim 1 , wherein each of the first support member and the second support member includes a metal material.

4. The display device of claim 1 , wherein the second support member includes an electromagnet.

5. The display device of claim 1 , wherein when the second support member moves from being disposed in the first display area to being disposed in the second display area,
a portion of the second support member overlaps the first display area.

6. The display device of claim 1 , wherein the second support layer includes a plurality of stretchable portions having a lattice shape in a plan view.

7. The display device of claim 6 , wherein each of the stretchable portions includes:
a plurality of openings having a shape extending longitudinally in a first direction and arranged in the first direction and a second direction orthogonal to the first direction.

8. The display device of claim 1 , wherein the second support member includes:
a third support layer overlapping the first display area; and
a fourth support layer movable from the first display area to the second display area or from the second display area to the first display area.

9. The display device of claim 8 , wherein when the fourth support layer is positioned in the first display area,
the second support member has a rectangular shape in a plan view.

10. The display device of claim 8 , wherein the third support layer and the fourth support layer have shapes that interlock with each other in a plan view.

11. The display device of claim 8 , wherein when the fourth support layer moves from the first display area to the second display area,
a portion of the fourth support layer overlaps the first display area.

12. The display device of claim 1 , wherein a distance between the bottom surfaces of the first and second support layers and a bottom surface of the display panel are equal to each other.

13. A display device comprising:
a display panel including a first display area and a second display area adjacent to the first display area;
a first support member disposed under the display panel and including a first support layer overlapping the first display area, and a second support layer overlapping the second display area, the second support layer having a thickness different from a thickness of the first support layer;
a second support member disposed under the first support member and movable from the first display area to the second display area or from the second display area to the first display area; and
an adhesive member including:
a first adhesive layer disposed on the first display area between the display panel and the first support layer, and
a second adhesive layer disposed on the second display area between the display panel and the second support layer.

14. The display device of claim 13 , wherein a thickness of the first adhesive layer is less than a thickness of the second adhesive layer.

15. A display device comprising:
a display panel including a first display area and a second display area adjacent to the first display area in a first direction;
a first support member disposed under the display panel and including a first support layer and a second support layer, the first and second support layers each including a bottom surface that is positioned on a same plane as each other; and
a second support member disposed under the first support member and movable in the first direction from being disposed in the first display area to being disposed in the second display area or from being disposed in the second display area to being disposed in the first display area,
wherein the second support layer includes a plurality of stretchable portions having a lattice shape in a plan view.

16. The display device of claim 15 , wherein the first support layer overlaps the first display area, and the second support layer overlaps the second display area.

17. The display device of claim 15 , wherein a thickness of the first support layer is greater than a thickness of the second support layer.

18. The display device of claim 15 , wherein when the second support member moves from being disposed in the first display area to being disposed in the second display area,
a portion of the second support member overlaps the first display area.

19. The display device of claim 15 , wherein each of the first support member and the second support member includes a metal material.

20. The display device of claim 15 , wherein each of the stretchable portions includes:
a plurality of openings having a shape extending longitudinally in a second direction orthogonal to the first direction and arranged in the first direction and the second direction.
