In summary, in the display panel, the manufacturing method thereof and the display device provided by the embodiments of the present application, at least one package detection structure is disposed on a side of the peripheral region of the packaging adhesive, which is close to the display region, and the package detection structure includes materials including luciferin and luciferase. Therefore, whether the package failure occurs can be judged according to whether the package detection structure emits light or not. In addition, the reaction response speed of the luciferin with oxygen under the condition of luciferase is high, so that whether oxygen invades can be rapidly detected. The luminescence efficiency of luciferin is 100% in the process of reacting with oxygen under the condition of luciferase, and the sensitivity of detecting whether oxygen is invaded is high. In addition, the packaging detection structure is arranged in the peripheral area, so that the packaging detection structure does not influence the luminous quality of the display area.
It will be apparent to those skilled in the art that various modifications and variations can be made to the present application without departing from the spirit or scope of the application. Thus, it is intended that the present application also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
