Abstract

Provided are a display panel, a method for manufacturing a display panel, and a display device. The display panel includes: a base substrate; an insulating layer disposed on the base substrate; a first groove provided in a transition region, a first cover layer and a common light-emitting functional layer. The first groove at least partially surrounds a display region. The first groove includes a first portion and a second portion. An aperture of the second portion on a side adjacent to the first portion is less than an aperture of the first portion on a side adjacent to the second portion. The first cover layer includes a first sub-cover layer disposed on the side of the insulating layer away from the base substrate and a second sub-cover layer. The second sub-cover layer covers a sidewall of the second portion. The common light-emitting functional layer is disconnected at the first groove.
