Display panel, manufacturing method thereof and display device

The invention discloses a display panel, a manufacturing method thereof and a display device, and belongs to the technical field of display. The display panel provided by the embodiment of the invention comprises a substrate, a plurality of light emitting devices, a packaging layer, a hydrophobic layer, an isolation part and a light conversion structure. The hydrophobic layer is arranged on the side, away from the substrate, of the packaging layer, and the hydrophobic layer can be hydrophobic. Therefore, the contact angle between the hydrophobic solution containing particles and the hydrophobic layer is small. Therefore, in the process of forming the light conversion structure by adopting an ink-jet printing process, the ductility of the solution mixed with the particles on the surface of the hydrophobic layer is relatively good, and the solution mixed with the particles can be fully spread on the surface of the hydrophobic layer, so that the distribution thickness of the solution mixed with the particles on the hydrophobic layer is relatively uniform; and thus, the thickness of the light conversion structure formed by subsequent curing is relatively uniform. Therefore, the display effect of the display panel can be effectively improved.
