Display panel and display device

A display panel, comprising:

• a substrate;
• an isolation structure, located on the substrate and comprising a partition portion, wherein the partition portion comprises a first end portion and a second end portion, the second end portion is located on a side, away from the substrate, of the first end portion, an orthographic projection of the first end portion on the substrate is within an orthographic projection of the second end portion on the substrate, and the isolation structure defines a plurality of first openings;
• a display function layer, located on the substrate and comprising a plurality of light-emitting devices correspondingly located in the plurality of first openings, wherein the light-emitting device comprises a first electrode, a light-emitting function layer and a second electrode stacked on the substrate, and each of the plurality of first openings limit one of the plurality of light-emitting devices;
• a first encapsulation layer, located on a side, away from the substrate, of the display function layer;
• and
• at least one optical function layer, located on a side, away from the substrate, of the light-emitting function layer and comprising a plurality of optical function units;
• wherein an orthographic projection of a part of an edge portion of a part of film layers of the light-emitting device on the substrate is within the orthographic projection of the second end portion on the substrate.
