Abstract
(EN)
Provided are a display panel with a stress relief structure, and a manufacturing method therefor. The display panel with a stress relief structure comprises: a substrate, wherein the substrate has a display area, a bending area and a peripheral area, and the bending area is located between the display area and the peripheral area; a metal trace, wherein the metal trace is disposed on the substrate and extends from the display area to the peripheral area; a planarization layer, wherein the planarization layer is located in the bending area and is disposed on the metal trace; and a pixel definition layer, wherein the pixel definition layer is located in the bending area and is disposed on the planarization layer, and at least one of the planarization layer and the pixel definition layer comprises a plurality of semi-cylinders parallel to each other.
