Claim 7:
8. A method for manufacturing a display panel, comprising:
providing a substrate having a display area and a non-display area;
forming a planarization layer on the display area and the non-display area of the substrate;
forming an organic light emitting element on a side of the planarization layer away from the substrate, wherein the organic light emitting element is located in the display area;
forming 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 method further comprises:
forming a third inorganic layer, causing that 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
providing a groove in a part of the planarization layer located in the non-display area, and filling the groove with a flexible water-oxidation resistant material;
wherein subsequent to the providing the first inorganic layer and prior to the providing the organic layer, the method further comprises:
forming a fourth inorganic layer in the display area, wherein a roughness of the fourth inorganic layer is greater than a roughness of the first inorganic layer.
