Abstract

A display device according to an exemplary embodiment of the present disclosure can include a back cover, a display panel disposed on the back cover, a polarizing plate disposed on the display panel, a barrier film disposed on the polarizing plate, and a side film which has one end disposed between the back cover and the display panel and another end disposed between the polarizing plate and the barrier film to enclose side surfaces of the display panel and the polarizing plate. Therefore, the moisture permeation into the polarization layer is delayed, which in turn improves the reliability of the display device.

First claim

What is claimed is:

1. A display device, comprising:
a back cover;
a display panel disposed on the back cover;
a polarizing plate disposed on the display panel;
a barrier film disposed on the polarizing plate; and
a side film which has one end disposed between the back cover and the display panel and another end disposed between the polarizing plate and the barrier film so as to enclose side surfaces of the display panel and the polarizing plate.

2. The display device according to claim 1 , wherein the side film includes a base layer and a barrier layer on the base layer.

3. The display device according to claim 2 , wherein the base layer between the base layer and the barrier layer is disposed at an outside from the side surfaces of the display panel and the polarizing plate.

4. The display device according to claim 1 , further comprising:
an adhesive member disposed between the display panel and the polarizing plate and the side film.

5. The display device according to claim 1 , wherein the display panel includes a substrate and at least one inorganic layer disposed on the substrate, and
the substrate and the at least one inorganic layer are bent so that one ends are disposed between the polarizing plate and the barrier film.

6. The display device according to claim 5 , wherein in an area in which the substrate and the at least one inorganic layer are bent, the side film is disposed so as to enclose the substrate and the at least one inorganic layer.

7. The display device according to claim 5 , further comprising:
an adhesive member disposed between one end of the bent substrate and the polarizing plate.

8. The display device according to claim 7 , wherein the adhesive member is disposed between the polarizing plate and the one end of the bent substrate from a top surface to a side surface of the polarizing plate.

9. The display device according to claim 1 , further comprising:
a roller which is connected to the back cover to wind or unwind the back cover and the display panel.

10. The display device according to claim 5 , further comprising:
an encapsulation layer disposed on the at least one inorganic layer; and
an encapsulation substrate which is disposed on the encapsulation layer through a first adhesive layer.

11. The display device according to claim 10 , further comprising:
a second adhesive layer disposed between the encapsulation substrate and the back cover.

12. The display device according to claim 11 , further comprising:
a third adhesive layer disposed between the display panel and the polarizing plate.

13. The display device according to claim 12 , further comprising:
a fourth adhesive layer disposed between the barrier film and the polarizing plate.

14. The display device according to claim 13 , wherein another end of the side film is disposed between the polarizing plate and the fourth adhesive layer.

15. The display device according to claim 14 , wherein one ends of the bent substrate and inorganic layer are disposed between the polarizing plate and the fourth adhesive layer.

16. The display device according to claim 10 , wherein one end of the side film is disposed between the back cover and the encapsulation substrate.

17. The display device according to claim 2 , wherein the base layer is configured by cyclo olefin polymer (COP) or polyethylene terephthalate (PET), and
the barrier layer is configured by an inorganic film or an organic film.
