Abstract

A display device according to an exemplary aspect of the present disclosure may include a display panel including a non-display area, a back cover supporting the display panel on one surface of the display panel, a roller for winding or unwinding the display panel and the back cover and side covers covering a portion of the non-display area of the display panel and a portion of a side surface of the back cover corresponding thereto, and including a plurality of unit side covers to thereby support the non-display area of the display panel when the roller is wound. Thus, stress generated during rolling can be reduced and accordingly, it is possible to prevent cracks and damage to the GIP unit.

First claim

What is claimed is:

1. A display device, comprising:
a display panel having a non-display area;
a back cover supporting the display panel on one surface of the display panel;
a roller configured to wind or unwind the display panel and the back cover; and
side covers covering a portion of the non-display area of the display panel and a portion of a side surface of the back cover corresponding thereto,
wherein the side covers include a plurality of unit side covers and support the non-display area of the display panel when the roller is wound,
wherein the roller includes a curved portion having a first curvature and a second curvature lower than the first curvature,
wherein the side covers are disposed to correspond to the second curvature; and
wherein the unit side cover has a rectangular parallelepiped shape and comprises: a body having a shape of “τ” in a cross-section; and an accommodation space provided inside and having side surfaces of the display panel and the back cover fitted and accommodated therein.

2. The display device of claim 1 , further comprising:
a printed circuit board disposed on one surface of the display panel; and
a flexible film having one end connected to a pad portion of the non-display area of the display panel and another end connected to the printed circuit board.

3. The display device of claim 2 , further comprising a cover unit disposed in a support area of the back cover and accommodating the printed circuit board.

4. The display device of claim 3 , wherein the roller further includes,
a flat portion corresponding to the support area of the back cover.

5. The display device of claim 3 , wherein the cover unit comprises:
a base plate disposed on a rear surface of the back cover; and
a cover plate disposed on an upper surface of the display panel.

6. The display device of claim 5 , wherein an upper surface of the cover plate has a curved surface, and
wherein the base plate and the printed circuit board are disposed to correspond to each other with the back cover interposed therebetween.

7. The display device of claim 2 , wherein the printed circuit board is disposed on a rear surface of the display panel, and
wherein the one end of the flexible film is connected to the pad portion of the display panel, and the another end of the flexible film is folded toward the rear surface of the display panel and is connected to the printed circuit board.

8. The display device of claim 1 , wherein the unit side cover comprises: a support portion for supporting the display panel inside the body; and a protrusion coupled to the back cover.

9. The display device of claim 8 , wherein the support portion is provided within the body except for the accommodation space.

10. The display device of claim 8 , wherein the protrusion protrudes from the support portion.

11. The display device of claim 1 , wherein the accommodation space comprises: a first accommodation space in which the side surface of the back cover that protrudes from the side surface of the display panel is accommodated; and a second accommodation space in which a remining side surface other than the protruding side surface of the back cover accommodated in the first accommodation space and the side surface of the display panel are accommodated.

12. The display device of claim 11 , wherein the first accommodation space and the second accommodation space have different heights, and a step is formed from the second accommodation space to the first accommodation space.

13. The display device of claim 12 , further comprising:
a polarizing plate disposed on another surface of the display panel;
an adhesive layer disposed between the display panel and the back cover; and
a sealing layer disposed on a side surface of the adhesive layer between the display panel and the back cover.

14. The display device of claim 13 , wherein side surfaces of the polarizing plate, the display panel, the sealing layer, and the back cover are partially inserted into the second accommodation space.

15. The display device of claim 13 , wherein a portion of an upper surface of the polarizing plate is in contact with the body, and
wherein the polarizing plate, the display panel, the side surface of the sealing layer, and a portion of an upper surface of the back cover are in contact with the support portion.

16. The display device of claim 11 , wherein the unit side cover includes one or more protrusions protruding to the first accommodation space.

17. The display device of claim 16 , wherein the side surface of the back cover is provided with an opening pattern formed of a plurality of holes, and
wherein the protrusions have shapes corresponding to the plurality of holes in the side surface of the back cover.

18. The display device of claim 1 , wherein the unit side cover is provided with at least one fastening hole for fastening with the unit side cover adjacent to an upper or lower end thereof, and
wherein the fastening hole connects the unit side covers through a wire.

19. The display device of claim 1 , further comprising a thin film coating provided on a surface of the accommodation space to prevent abrasion due to contact when the display panel and the back cover are fastened.
