Abstract

Disclosed is an electronic device. An electronic device according to an embodiment may comprise: a display panel of which at least a portion is flexible; a window disposed above at least the portion of the display panel; an anti-reflection layer (AR/LR) disposed above at least a portion of the window; and an anti-glare layer (AG) disposed below at least the portion of the window. Various other embodiments are also possible.

First claim

The invention claimed is:

1. An electronic device comprising:
a display panel of which at least a portion is flexible, the display panel including a foldable region and flat regions at both sides of the foldable region;
a window disposed above at least the portion of the display panel, the window including a groove arranged in a region corresponding to the foldable region, wherein a thickness of the region corresponding to the foldable region is thinner than a thickness of other regions corresponding to the flat regions;
an anti-reflection layer (AR/LR) entirely disposed inside the groove, above at least a portion of the window;
an anti-glare layer (AG) disposed below at least the portion of the window;
a polarization layer disposed below the window; and
an optical clear adhesive layer (OCA) disposed between the polarization layer and the anti-glare layer.

2. The electronic device of claim 1 , further comprising:
a shock protection layer formed of polyethylene terephthalate (PET) disposed below the window.

3. The electronic device of claim 1 , wherein the anti-glare layer is overlapped at least with the foldable region.

4. The electronic device of claim 1 , wherein the window comprises a polyimide (PI) resin.

5. The electronic device of claim 1 , further comprising:
a plate of which one surface comes in touch with the respective flat regions disposed at the both sides of the foldable region;
a bracket facing another surface of the plate; and
a slip layer disposed between the bracket and the plate.

6. The electronic device of claim 5 , wherein the slip layer comprises an iterative pattern which is formed by slippable materials and void spaces.

7. The electronic device of claim 5 , wherein, in the foldable region, a void space is offered between the display panel and the window.

8. The electronic device of claim 7 , further comprising:
an adhesive layer disposed in at least a portion of the flat region and spacing the display panel and the window apart.

9. The electronic device of claim 1 , wherein the window comprises a first window disposed below the anti-reflection layer, and a second window disposed below the first window.

10. The electronic device of claim 9 , wherein the first window and the second window are formed of heterogeneous materials.

11. The electronic device of claim 1 , wherein the anti-reflection layer destructively interferes at least a portion of light reflected from the anti-reflection layer.

12. The electronic device of claim 1 , wherein the window is at least partially exposed to the exterior of the electronic device.
