Embodiment Construction

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0035] As mentioned in the background technology, the display panel in the prior art has the problem that the metal leads located in the bending area are prone to breakage. The inventors have found through research that the reason for this problem is that the metal leads are very thin and reflect a strong Brittleness and poor deformation ability make the bending resistance of the metal lead poor. When the bending degree of the metal lead is large, the metal lea...

Abstract

The invention discloses a display panel and a display device, wherein the display panel includes a bending area; the display panel also includes: a base substrate; a plurality of metal leads arranged on one side of the base substrate and at least A part overlaps with the bending area; a planarization layer covers at least the part where the metal lead overlaps with the bending area; a part of the planarization layer located in the bending area is formed with a plurality of grooves , the plurality of grooves are filled with elastomer. The invention solves the problem that the metal leads in the bending area of ​​the display panel are easily broken, reduces the risk of breaking the metal leads in the bending area, and further improves the display effect.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] With the development of display technology, flexible display technology shows more and more extensive application prospects, and promotes the development of full screen. [0003] During the production process of the full screen, the bonding module needs to be folded to the back of the screen through the bending area to realize the full screen display. However, during the bending process, the metal wires in the bending area are easily broken, and the inorganic layer (SiOx or SiNx) in the bending area is also easily broken, which will also cause the upper metal wires in the bending area to break, which will cause the signal to be unable to be transmitted to the Screen body, resulting in bad line or black screen. Contents of the invention [0004] In view of this, the purpose of the p...
