Claim 0:
1. A display panel, comprising:
a substrate having a display area and a non-display area;
a planarization layer covering the display area and the non-display area of the substrate;
an organic light emitting element located in the display area and located at a side of the planarization layer away from the substrate;
an encapsulation structure wrapping the organic light emitting element, wherein the encapsulation structure comprises a first inorganic layer, an organic layer and a second inorganic layer which are sequentially stacked, the first inorganic layer and the second inorganic layer extend into the non-display area, and the first inorganic layer is arranged close to the planarization layer;
wherein the display panel further comprises:
a third inorganic layer, wherein the third inorganic layer is located in the non-display area and is located between the planarization layer and the first inorganic layer; and/or
a part of the planarization layer located in the non-display area is provided with a groove, and the groove is filled with a flexible water-oxidation resistant material;
wherein the display panel further comprises a fourth inorganic layer located in the display area and between the first inorganic layer and the organic layer, and a roughness of the fourth inorganic layer is greater than a roughness of the first inorganic layer.
