Abstract

A display device includes a display panel having a first region, a second region, and a bending region which is between the first region and the second region and at which the display panel is bendable, an anti-reflection layer on the display panel and including a color filter, and a shock absorbing layer facing the display panel with the anti-reflection layer therebetween. The shock absorbing layer extends from the first region of the display panel and into the bending region thereof.

First claim

What is claimed is:

1. An electronic device comprising:
a display device comprising:
a display panel including a first region including a display region, a second region, and a bending region which is between the first region and the second region and at which the display panel is bendable;
an anti-reflection layer on the display panel and comprising a color filter; and
a shock absorbing layer facing the display panel with the anti-reflection layer therebetween,
wherein the shock absorbing layer corresponds to the first region of the display panel and extends from the first region to the bending region.

2. The electronic device of claim 1 , wherein the shock absorbing layer comprises a polymer.

3. The electronic device of claim 1 , wherein the shock absorbing layer has a thickness of about 50 micrometers to about 80 micrometers.

4. The electronic device of claim 1 , further comprising a driving circuit in the second region of the display panel.

5. The electronic device of claim 4 , further comprising a cover layer which covers the driving circuit in the second region and extends from the driving circuit to overlap the shock absorbing layer.

6. The electronic device of claim 5 , further comprising a protective pattern between the cover layer and the shock absorbing layer.

7. The electronic device of claim 6 , wherein the protective pattern which is between the cover layer and the shock absorbing layer, overlaps the second region of the display panel and does not overlap the bending region of the display panel.

8. The electronic device of claim 1 , wherein the shock absorbing layer which extends from the first region of the display panel to the bending region thereof, further extends to the second region.

9. The electronic device of claim 1 , wherein the shock absorbing layer which extends from the first region of the display panel to the bending region thereof comprises:
a first portion corresponding to the first region;
a second portion corresponding to the bending region; and
the first portion and the second portion of the shock absorbing layer being integral with each other.

10. The electronic device of claim 9 , wherein
the bending region of the display panel is exposed outside of the anti-reflection layer comprising the color filter, and,
the second portion of the shock absorbing layer contacts the bending region of the display panel which is exposed outside of the anti-reflection layer comprising the color filter.

11. The electronic device of claim 1 , further comprising a window module facing the anti-reflection layer, with the shock absorbing layer therebetween,
wherein
the window module includes a window base layer and a window protective layer in order from the shock absorbing layer,
each of the shock absorbing layer and the window protective layer has an elastic modulus, and
the elastic modulus of the shock absorbing layer is lower than the elastic modulus of the window protective layer.

12. The electronic device of claim 1 , wherein the first region of the display panel comprises:
the display region including a pixel; and
a non-display region adjacent to the display region.

13. The electronic device of claim 1 , wherein the anti-reflection layer further comprises:
the color filter provided in plural including a plurality of color filters, and
a division layer between the plurality of color filters.

14. The electronic device of claim 1 , further comprising an input sensor between the display panel and the anti-reflection layer.
