Display panel and display device

The embodiment of the utility model provides a display panel and a display device, relates to the technical field of display, and is used for improving the reliability of a packaging structure and reducing the risk of poor display of the display panel. The display panel comprises a substrate, a pixel defining layer, a plurality of isolation structures and a packaging structure. The pixel defining layer is arranged on one side of the substrate, the pixel defining layer comprises a plurality of openings, and each opening is configured to define a light emitting area of one sub-pixel. The multiple isolation structures are arranged on the side, away from the substrate, of the pixel defining layer, each isolation structure surrounds at least one opening, and grooves are formed in the side walls of the isolation structures. The packaging structure is arranged on the side, away from the substrate, of the multiple isolation structures and comprises a first inorganic packaging layer, an organic packaging layer and a second inorganic packaging layer which are sequentially stacked in the direction away from the substrate. The spreading coefficient of the organic encapsulation layer on the first inorganic encapsulation layer is greater than the spreading coefficient of the organic encapsulation layer on the second inorganic encapsulation layer. The display panel is used for displaying images.
