The invention discloses a display panel, a manufacturing method thereof and a display device. The display panel includes: an array layer; a light-emitting device layer located on the array layer; a package structure located on the side of the light-emitting device layer away from the array layer, and the package structure includes a metal oxide layer; an adhesive layer located on the side of the package structure away from the light-emitting device layer ; Wherein, the orthographic projection of the packaging structure on the array layer is located within the orthographic projection of the adhesive layer on the array layer, and the orthographic projection of the adhesive layer on the array layer is larger than the orthographic projection of the packaging structure on the array layer. The bonded edge of the adhesive layer is not in contact with the metal oxide layer produced by the atomic layer deposition process, which avoids warping or even peeling off at this position due to poor bonding performance, and ensures the performance reliability of the display panel.
