Abstract:
Provided in the present application are a display panel and a manufacturing method therefor, and a display apparatus. The display panel comprises a display area and a non-display area extending around the display area. The display panel comprises: a substrate; an array structure layer, which is arranged on the substrate, wherein a driving circuit is arranged in the array structure layer, and the array structure layer comprises a first portion and a second portion, the first portion being a projection portion of the display area on the array structure layer, the second portion being a projection portion of the non-display area on the array structure layer, and the second portion being provided with a groove filled with a first organic material; an organic planarization layer, which covers the first portion and comprises the first organic material; a light-emitting device layer, which is arranged on the organic planarization layer, wherein the light-emitting device layer corresponds to the display area and is electrically connected to the driving circuit; and an encapsulation layer, which covers the light-emitting device layer and extends to the second portion. By means of the technical solution, the problem of black spots generating at the edge of a display panel can be ameliorated, and the service life of the display panel can be prolonged.
