Abstract
A display panel and a manufacturing method thereof are provided. In the manufacturing method of the display panel, a corner-cutting area of a to-be-cut display panel is provided with a cutting groove. The cutting groove penetrates a buffer layer and extends into a flexible substrate. Furthermore, the cutting groove is provided with an inorganic encapsulation layer and a sacrificial layer. Therefore, when cutting the to-be-cut display panel along the cutting groove, cracks generated during a process can be reduced, thereby alleviating a problem of micro-cracks affecting a packaging effect of conventional display panels during a secondary cutting process.
