Abstract

The embodiment of the invention provides a display panel and a display device, which relate to the technical field of display and can improve the problem that external water and oxygen invade a display area. The display panel is provided with a display area and a peripheral area. The display panel comprises a substrate, a pixel driving circuit arranged on the substrate and located in a display area, and a flat layer arranged on the side, away from the substrate, of the pixel driving circuit, and the flat layer is further located in the peripheral area. The display panel further comprises a signal line electrically connected with the pixel driving circuit, the signal line comprises a power line used for providing power signals for the pixel driving circuit, and the power line extends into the peripheral area. The flat layer is provided with a slot in the peripheral area, and the slot surrounds the display area by a circle. In the thickness direction of the substrate, the slot penetratesthrough the flat layer to expose the power line, and at least one side surface, exposed by the slot, of the power line is of a comb tooth structure.

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] In the production process of display panels, packaging is currently a major problem. If the encapsulation fails, outside water and oxygen can easily intrude into the display area, making the light-emitting organic materials in the display area, for example, invalid, resulting in black spots and other undesirable phenomena on the display panel. Contents of the invention [0003] Embodiments of the present invention provide a display panel and a display device, which can solve the problem of outside water and oxygen intruding into the display area. [0004] In order to achieve the above object, embodiments of the present invention adopt the following technical solutions: [0005] In a first aspect, a display panel is provided, which has a display area and a peripheral area; the display panel includes: ...
