Abstract
Disclosed are a flexible display and an electronic device including the same, in the flexible display, a back plate has an improved structure so as to stably support a display panel even during repeated folding and unfolding operations, and also the flexible display can prevents sagging or deformation of specific constituent elements therein.
Claims20
A flexible display, comprising:
- a display panel;
- and
- a back plate having a folding portion and a non-folding portion, the back plate including:
- a first layer formed of a material having a stiffness higher than a stiffness of the display panel,
- a first opening pattern formed in the first layer and corresponding to the folding portion,
- a second opening pattern formed in the first layer and corresponding to the non-folding portion, and
- a skin layer on at least one surface of the first layer, wherein the skin layer is uniformly disposed at the folding portion and the non-folding portion to prevent the first opening pattern and the second opening pattern from being visible,
- wherein the back plate has edges extending in a direction crossing a length direction of the first opening pattern and all of the first opening pattern in the folding portion and the second opening pattern in the non-folding portion are spaced from the edges of the back plate.

- a second opening pattern formed in the first layer and corresponding to the non-folding portion, the second opening pattern having a second density of empty space, and
- a skin layer on at least one surface of the first layer,
- wherein the skin layer is uniformly disposed at the folding portion and the non-folding portion, and the skin layer has a higher elastic restoration ability than the first layer, and
- wherein the back plate includes a first adhesive layer between the first layer and the skin layer.
