1. A display panel, comprising:
a panel body comprising a functional area and a display area surrounding at least a portion of the functional area;
a polarizing layer disposed on a light-emitting side of the panel body; and
a cover module disposed on a side of the polarizing layer away from the panel body, wherein at least a portion of the cover module corresponding to the functional area has a total in-plane phase difference of less than or equal to 100 nm or greater than or equal to 7500 nm;
wherein the cover module comprises:
a first optical adhesive layer disposed on the side of the polarizing layer away from the panel body;
a first flexible layer disposed on a side of the first optical adhesive layer away from the polarizing layer;
a second optical adhesive layer disposed on a side of the first flexible layer away from the polarizing layer;
a hardened layer disposed on a side of the second optical adhesive layer away from the polarizing layer;
a third optical adhesive layer disposed on a side of the hardened layer away from the polarizing layer; and
a second flexible layer disposed on a side of the third optical adhesive layer away from the polarizing layer;
wherein an angle between an orientation direction of the first flexible layer and an orientation direction of the second flexible layer is less than or equal to 15°, the orientation direction of the first flexible layer is a direction in which the first flexible layer is stretched, and the orientation direction of the second flexible layer is a direction in which the second flexible layer is stretched.
