Abstract
A display panel has a display area and a frame area located at at least one side of the display area. The display panel includes a base, at least one groove, a plurality of light-emitting devices, at least one first fixing component, and a sealant disposed at least in the frame area. At least one groove is arranged at a side of the base, and the at least one groove is located in the frame area. Each first fixing component includes a first portion and a second portion, and the first portion of the first fixing component is embedded in a groove. The sealant is located at the side of the base having the at least one groove, and the second portion of the first fixing component is embedded in the sealant.

- wherein forming at least one groove at a side of the base, includes:
- forming a photoresist pattern on a side of the base;
- etching the base by using the photoresist pattern as a mask to form at least one first accommodating portion, each first accommodating portion including a bottom wall and a side wall connected to the bottom wall, and the side wall including a first region and a second region;
- forming a corrosion-resistant film in the first region of the side wall and on the bottom wall, the corrosion-resistant film exposing the second region of the side wall, and the second region of the side wall being connected to the bottom wall, and the second region of the side wall and a main surface of the base proximate to the sealant having a distance therebetween;
- and
- etching the second region of the side wall by using a wet etching process to form a second accommodating portion, the second accommodating portion extending in a direction parallel to the main surface of the base proximate to the sealant, and one end of the second accommodating portion being connected to the first accommodating portion.
