Electronic device

1. A display device, comprising:

upper functional layers;

a display panel disposed below the upper functional layers; and

lower functional layers disposed below the display panel,

wherein the lower functional layers comprise:

a first lower functional layer disposed below the display panel and including a first hole; and

a second lower functional layer spaced apart from the display panel with the first lower functional layer interposed therebetween and including a second hole overlapping the first hole, and

wherein a size of the first hole is greater than a size of the second hole.

2. The display device of claim 1 , wherein a portion of the display panel, which overlaps the first hole, is configured to display an image.

3. The display device of claim 1 , wherein the display panel includes a third hole overlapping the first hole and the second hole.

4. The display device of claim 3 , wherein a size of the third hole is smaller than each of the size of the first hole and the size of the second hole.

5. The display device of claim 3 , wherein the upper functional layers comprise a light blocking pattern disposed on the display panel, and

wherein, when viewed in a plane, the light blocking pattern overlaps a sidewall of the display panel, which defines the third hole.

6. The display device of claim 5 , wherein, when viewed in the plane, the light blocking pattern is surrounded by a sidewall of the first lower functional layer, which defines the first hole.

7. The display device of claim 5 , wherein, when viewed in the plane, a sidewall of the first lower functional layer, which defines the first hole, does not overlap the light blocking pattern.

8. The display device of claim 3 , wherein the upper functional layers comprise:

a window;

an impact absorbing layer disposed between the window and the display panel; and

a hard coating layer disposed between the impact absorbing layer and the display panel, and

wherein a portion of the hard coating layer is exposed through the third hole.

9. The display device of claim 1 , wherein the upper functional layers comprise:

a window; and

an adhesive layer disposed between the window and the display panel, the adhesive layer being attached to the window, and

wherein the adhesive layer has an area smaller than an area of the window.

10. The display device of claim 9 , wherein the upper functional layers further comprise a protective layer disposed on the window, and

wherein a sidewall of the protective layer protrudes outward more than a sidewall of the window.

11. The display device of claim 1 ,

wherein the first lower functional layer comprises:

a first cushion adhesive layer;

a barrier film disposed below the first cushion adhesive layer;

a cushion layer disposed below the barrier film; and

a second cushion adhesive layer disposed below the cushion layer.

12. The display device of claim 1 , wherein the upper functional layers, the display panel, and the lower functional layers are configured to fold and unfold about a folding axis, which extends in a predetermined direction.

13. The display device of claim 1 , wherein a folding area to be folded and unfolded is defined in the display panel, and an opening is defined in a portion of the second lower functional layer overlapping the folding area.

14. An electronic device, comprising:

upper functional layers;

a display panel disposed below the upper functional layers;

lower functional layers disposed below the display panel; and

an electronic module inserted in a hole defined in the lower functional layers, wherein the lower functional layers comprise:

a first lower functional layer disposed below the display panel and including a first hole having a first width in a first direction; and

a second lower functional layer disposed below the first lower functional layer and including a second hole overlapping the first hole and having a second width in the first direction,

wherein the second width is different from the first width,

wherein the electronic module faces a first sidewall of the first lower functional layer defining the first hole and a second sidewall of the second lower functional layer defining the second hole in the first direction; and

wherein the electronic module is spaced apart from the first sidewall and the second sidewall in the first direction.

15. The electronic device of claim 14 , wherein the first width of the first hole is greater than the second width of the second hole.

16. The electronic device of claim 14 , wherein the display panel includes a third hole overlapping the first hole and the second hole and having a third width in the first direction, and

wherein the third width is smaller than each of the first width and the second width.

17. The electronic device of claim 16 , wherein the upper functional layers comprise a light blocking pattern disposed on the display panel, and

wherein, when viewed in a plane, the light blocking pattern overlaps a sidewall of the display panel, which defines the third hole.

18. The electronic device of claim 17 , when viewed in the plane, wherein the first sidewall of the first lower functional layer does not overlap the light blocking pattern.

19. The electronic device of claim 16 , wherein the upper functional layers comprise:

a window;

an impact absorbing layer disposed between the window and the display panel; and

a hard coating layer disposed between the impact absorbing layer and the display panel, and

wherein a portion of the hard coating layer is exposed through the third hole.

20. The electronic device of claim 16 , wherein the upper functional layers comprise:

a window;

an adhesive layer disposed between the window and the display panel, the adhesive layer being attached to the window; and

a protective layer disposed on the window,

wherein a sidewall of the window protrudes outward more than a sidewall of the adhesive layer, and

wherein a sidewall of the protective layer protrudes outward more than the sidewall of the window.
