Abstract

An electronic device includes an upper member, a first adhesive layer, and a second adhesive layer. The upper member includes a window having a rear surface opposite to a front surface, a protective layer on the front surface of the window, and an impact absorbing layer on the rear surface of the window. The display panel is below the upper member, and the first adhesive layer is between the window and the protective layer. The second adhesive layer is between the window and the impact absorbing layer. An edge of the front surface of the window is exposed by the first adhesive layer, and an edge of the second adhesive layer is exposed by the window.

First claim

What is claimed is:

1. An electronic device, comprising:
an upper member which comprises a window having a front surface and a rear surface opposite to the front surface, a protective layer disposed on the front surface of the window, and an impact absorbing layer disposed on the rear surface of the window;
a display panel disposed below the upper member;
a first adhesive layer disposed between the window and the protective layer; and
a second adhesive layer disposed between the window and the impact absorbing layer, wherein an edge of the front surface of the window is exposed by the first adhesive layer and wherein an edge of the second adhesive layer is exposed by the window.

2. The electronic device of claim 1 , wherein the edge of the second adhesive layer exposed from the window surrounds the first adhesive layer.

3. The electronic device of claim 1 , wherein an edge of a rear surface of the protective layer is exposed by the first adhesive layer.

4. The electronic device of claim 1 , further comprising a light blocking layer which is disposed between the second adhesive layer and the impact absorbing layer and disposed along an edge of the impact absorbing layer.

5. The electronic device of claim 1 , further comprising an anti-fingerprint layer disposed on a rear surface of the protective layer that is exposed from the first adhesive layer.

6. The electronic device of claim 1 , further comprising an anti-reflection member disposed between the upper member and the display panel.

7. The electronic device of claim 6 , further comprising a protective film disposed below the display panel.

8. The electronic device of claim 7 , wherein a side surface of the second adhesive layer, a side surface of the impact absorbing layer, a side surface of the anti-reflection member, a side surface of the display panel, and a side surface of the protective film, which are adjacent to the edge of the second adhesive layer exposed from the window, are aligned with each other.

9. The electronic device of claim 7 , further comprising a cushion member disposed below the protective film.

10. The electronic device of claim 9 , further comprising a metal plate disposed below the cushion member.

11. A display module, comprising:
an upper member which comprises a window having a front surface and a rear surface opposite to the front surface, a protective layer disposed on the front surface of the window, and an impact absorbing layer disposed on the rear surface of the window;
a releasing film configured to cover the upper member;
a display panel disposed below the upper member;
a first adhesive layer disposed between the window and the protective layer; and
a second adhesive layer disposed between the window and the impact absorbing layer, wherein an edge of the front surface of the window is exposed by the first adhesive layer and wherein an edge of the second adhesive layer is exposed by the window.

12. The display module of claim 11 , wherein the edge of the second adhesive layer exposed from the window surrounds the first adhesive layer.

13. The display module of claim 11 , wherein an edge of a rear surface of the protective layer is exposed by the first adhesive layer.

14. The display module of claim 11 , further comprising a light blocking layer which is disposed between the second adhesive layer and the impact absorbing layer and along an edge of the impact absorbing layer.

15. The display module of claim 11 , further comprising an anti-fingerprint layer disposed on a rear surface of the protective layer that is exposed from the first adhesive layer.

16. The display module of claim 11 , further comprising:
an anti-reflection member between the upper member and the display panel; and
a protective film disposed below the display panel.

17. The display module of claim 16 , wherein a side surface of the second adhesive layer, a side surface of the impact absorbing layer, a side surface of the anti-reflection member, a side surface of the display panel, and a side surface of the protective film, which are adjacent to the edge of the second adhesive layer exposed from the window, are aligned with each other.

18. The display module of claim 17 , wherein the releasing film comprises:
a first film overlapping the second adhesive layer; and
a second film protruding from the first film in one direction.

19. The display module of claim 18 , wherein the protective layer comprises:
a first section overlapping the first film; and
a second section overlapping the second film.

20. The display module of claim 19 , further comprising an additional anti-fingerprint layer disposed between the releasing film and the protective layer.
