Abstract

A display device including a display panel including a folding area and a non-folding area adjacent along a first direction, a support layer facing the display panel with a barrier layer therebetween, openings defined in the support layer and corresponding to the folding area, a cushion layer facing the display panel with the support layer therebetween, and a barrier adhesive layer between the barrier layer and the support layer, the barrier adhesive layer including a first barrier portion and a second barrier portion spaced apart from each other along the first direction with the plurality of openings of the support layer therebetween.

First claim

What is claimed is:

1 . An electronic device comprising:
a display panel comprising a foldable area at which the display panel is foldable; a support layer facing the display panel, a plurality of openings which are defined the support layer and correspond to the foldable area of the display panel; and a cushion layer facing the display panel with the support layer therebetween, the cushion layer comprising a first cushion layer and a second cushion layer spaced apart from each other at the foldable area of the display panel.

2 . The electronic device of claim 1 , further comprising:
a barrier layer disposed between the display panel and the support layer; and a barrier adhesive layer between the barrier layer and the support layer, the barrier adhesive layer comprising: a first barrier adhesive layer between the barrier layer and the support layer; and a second barrier adhesive layer between the barrier layer and the display panel, wherein the first barrier adhesive layer comprises a first barrier portion and a second barrier portion spaced apart from each other with the plurality of openings therebetween.

3 . The electronic device of claim 2 , further comprising a space which is defined between the barrier layer and the support layer and overlaps the plurality of openings.

4 . The electronic device of claim 2 , wherein the barrier layer comprises a colored polyimide film.

5 . The electronic device of claim 2 , wherein the barrier layer comprises a light shielding material.

6 . The electronic device of claim 1 , wherein the barrier layer has a first clastic modulus, and the cushion layer has a second clastic modulus lower than the first clastic modulus of the support layer.
