Display panel and display device

The invention provides a display panel and a display device, the display panel comprises a substrate, a plurality of light emitting devices, a light shielding layer and a phase change structure, the light emitting devices are arranged on one side of the substrate, and the plurality of light emitting devices are arranged at intervals. The light shielding layer is arranged on one side of the substrate, at least part of the light shielding layer is located between the adjacent light emitting devices, the phase change structure is arranged in the light shielding layer, the phase change structure comprises a first phase change part and a second phase change part wrapping the first phase change part, and the porosity corresponding to the second phase change part is larger than that of the first phase change part. In the embodiment of the invention, the porosity of the second phase change part is set to be greater than that of the first phase change part, so that the phase change structure can absorb more external h
