Abstract
A flexible element configured to be disposed on a surface of a non-display substrate of a flexible display panel includes: a first base layer and a second base layer which are oppositely arranged with each other; and a buffer layer sandwiched between the first base layer and the second base layer. The flexible element can be bent around a bending axis. A projection of the buffer layer on a plane perpendicular to the bending axis is wave-shaped.

A flexible element configured to be disposed on a flexible display panel, the flexible element comprising:
- a first base layer and a second base layer which are oppositely arranged with each other;
- and
- at least one buffer layer sandwiched between the first base layer and the second base layer,
- wherein the flexible element is capable of bending around a bending axis, and a projection of the at least one buffer layer on a plane perpendicular to the bending axis is in a wave shape,
- wherein the first base layer and the second base layer respectively define a plurality of apertures therein, and
- wherein a distribution density of the plurality of apertures in a bending region with a larger radius of curvature of the first base layer is greater than that in a bending region with a smaller radius of curvature of the first base layer;
- and the distribution density of the plurality of apertures in a bending region with a larger curvature radius of the second base layer is greater than that in the bending region with a smaller curvature radius of the second base layer.
