Abstract

The embodiment of the invention provides a display panel and a display device. The display panel comprises a display layer, a packaging layer and a functional film layer which are stacked in sequence, and the display layer comprises a plurality of light-emitting devices; the functional film layer is located on the side, away from the display layer, of the packaging layer, the functional film layer at least comprises an elastic recovery layer, the display panel comprises a bendable area, and the elastic recovery layer is at least located in the bendable area. The elastic recovery layer can assist other film layers in the panel in arched recovery after bending, and the risks that the film layers are peeled off or broken due to multiple times of bending and the bent part is arched and cannot be recovered in the flattened state are reduced. Meanwhile, the elastic recovery layer can play a role in protecting the packaging layer on the light-emitting device when the display panel bears impact force, display abnormality caused by packaging failure is avoided, and therefore the impact resistance of the display panel is improved.

Description

technical field [0001] The invention belongs to the field of display technology, and more specifically relates to a display panel and a display device. Background technique [0002] With the development of display technology, portable display devices such as mobile phones and tablet computers have become indispensable products in people's lives. Large-size display screens can improve the visual experience of users and are very popular among users. However, large-size display screens also make the display devices inconvenient to carry, and thus foldable display devices appear. The foldable display device has a large-sized display screen in the unfolded state and a small display screen in the folded state, which can be applied to different application scenarios, and can obtain a small volume for easy portability. The foldable display device brings multi-functional application scenarios and visual impact to users. In practical applications, the display screen will go through ...
