Abstract
A display panel and a display device are disclosed in the present application. The display panel further includes a panel body, a back plate, and a bending protecting layer. The panel body includes a display portion, and the display portion is located in a planar display area and a curved display area. The back plate is provided on a side of the display portion and in the planar display area and the curved display area. The bending protecting layer is disposed on a side of the back plate away from the display portion and at least in the corner curved sub-area. Material of the bending protecting layer includes a plastic metal material.
Claims19
A display panel, comprising a planar display area and a curved display area adjacent to the planar display area, wherein the curved display area comprises a plurality of side curved sub-areas located on a peripheral side of the planar display area and a corner curved sub-area located between adjacent side curved sub-areas of the plurality of side curved sub-areas, and the display panel further comprises:
- a panel body including a display portion located in the planar display area and the curved display area;
- a back plate provided on a side of the display portion and located in the planar display area and the curved display area;
- and
- a bending protecting layer disposed on a side of the back plate away from the display portion and located at least in the corner curved sub-area;
- wherein material of the bending protecting layer comprises a plastic metal material;
- and
- wherein the thickness of the bending protecting layer is less than or equal to 10 microns, in a case that a compression amount of the display portion in the curved display area is less than or equal to 300 microns;
