Abstract
Disclosed is a method for manufacturing a display panel including: forming a base structure in a target region on a base substrate; forming a display structure layer on the base substrate on which the base structure is formed; forming an annular groove in the display structure layer in a region which an orthographic projection of the base structure on the display structure layer falls within, the base structure being exposed in the annular groove; and removing the base structure surrounded by the annular groove to separate the display structure layer surrounded by the annular groove from the base substrate.
