Abstract

The invention provides a display panel and a display device.The display panel comprises a bridging region, and the bridging region comprises a source and drain electrode located on one side of a substrate, an anode located on the source and drain electrode, a cathode located on the anode and a capping layer located on the cathode; and a plurality of concave-convex embedded structures are formed in the bridging area through the two combined side faces of the cathode and the sealing cover layer, the binding force between the cathode and the sealing cover layer located on the cathode is enhanced, the technical problem that the cathode is prone to being separated from the adjacent sealing cover layer under the stress effect is solved, and the display effect of the display panel can be improved.

Description

technical field [0001] The present application relates to the display field, in particular to a display panel and a display device. Background technique [0002] In flat panel display technology, Organic Light-Emitting Diode (OLED) display has many advantages such as thinness, active light emission, fast response speed, large viewing angle, wide color gamut, high brightness and low power consumption, etc., and has gradually become the successor. The third generation display technology after liquid crystal display. [0003] In the prior art, the OLED display panel is generally used as a flexible display panel. For the use environment that requires repeated folding, the flexible display panel naturally has good adaptability, so that the flexible display panel has a wide range of application fields. When the flexible display substrate is bent with a large curvature, the cathode is subjected to stress, and it is easy to separate from its adjacent film layer, resulting in a tech...
