Organic light-emitting display substrate, display panel and display device

Abstract

The invention discloses an organic light-emitting display substrate, a display panel and a display device. The organic light-emitting display substrate comprises a bending region and a non-bending region, wherein the extension direction of the bending axis of the bending region is a first direction; and a surface of at least one film layer of a buffer layer, a gate insulating layer, a first insulating layer, and a second insulating layer in the organic light emitting display substrate away from a flexible substrate includes a microstructure, and at least one film layer on one side of the microstructure away from the flexible substrate forms a bending structure, and the extension direction of the bending axis of the bending structure is the same as the first direction. The technical schemeprovided by an embodiment of the invention enables the at least one conductive film layer of one side of the surface of the microstructure away from the flexible substrate to form the bending structure, and the bending structure can play a role of cushioning stress when the bending region is bent, thereby reducing the probability of breakage of each conductive film layer and separation from the adjacent insulating layer in the bending region.
