Abstract

The invention provides a display panel and a display device. The display panel comprises a plane area, a first curved surface area and two second curved surface areas, wherein the plane area comprises a first side edge and a second side edge adjacent to the first side edge; the two second curved surface areas are connected with the first side edge and the second side edge respectively; and the first curved surface area is located between the two second curved surface areas and corresponds to the corner of the plane area. The display panel further comprises a supporting layer and a main panel body, wherein the supporting layer comprises a bent first part located in the first curved surface area and bent second parts located in the second curved surface areas; the main panel body is disposed on the first part and the second parts and bends with the first part and the second parts; and the shrinkage rate of the first part is greater than the shrinkage rate of the second parts. When the display panel is subjected to 3D laminating process treatment, the first part shrinks, so the main panel body and a curved surface cover plate are tightly laminated, and the problems of laminating wrinkles, laminating bubbles and the like of the display panel in the first curved surface area are avoided.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] When the curved screen display module is 3D laminated, there will be redundant parts at the corners of the curved screen surface, which will cause lamination wrinkles and affect the display effect. In order to avoid fitting wrinkles, before 3D bonding, the redundant parts will be cut off to ensure that after 3D bonding, a shape that meets the requirements of the corners of the curved surface can be formed, but because there are cutting seams in the corners, there will also be Affect the user's visual experience of full-screen display. Contents of the invention [0003] Embodiments of the present invention provide a display panel and a display device, which can solve the problem of lamination wrinkles in the first curved area of ​​the display panel. [0004] An embodiment of the present invention prov...
