Abstract
A display panel and a manufacturing method thereof are provided. The display panel includes a non-display area which is provided with a bending area. The bending area includes a substrate layer, a metal wiring layer, and a first planarization layer sequentially disposed. A groove is defined on a surface of the substrate layer away from the metal wiring layer, where a groove wall of the groove extends along a curved surface or a flat surface to a groove bottom of the groove to let an orthographic projection of the groove bottom of the groove on the substrate layer fall within an orthographic projection of an opening of the groove on the substrate layer, so that the metal wiring layer is located in a neutral layer or close to the neutral layer.
