1. A display panel, comprising:
a flexible substrate layer;
a display layer disposed on the flexible substrate layer;
a touch control layer disposed on one surface of the display layer away from the flexible substrate layer;
a polarizer disposed on one surface of the touch control layer away from the display layer;
a cover plate disposed on one surface of the polarizer away from the touch control layer;
a buffer layer disposed on one surface of the flexible substrate layer away from the display layer, wherein the buffer layer comprises a material having Poisson's ratio of less than 0.1; and
at least one adhesive layer disposed between two adjacent layers in a layered structure of the display panel, wherein the adhesive layer comprises a material having Poisson's ratio of less than 0.1;
wherein the material of the adhesive layer comprises at least one of a polyurethane based optical adhesive, an acrylic based optical adhesive, and a rubber based optical adhesive, and side chains of the polyurethane based optical adhesive, side chains of the acrylic based optical adhesive, and side chains of the rubber based optical adhesive are all modified by liquid crystal molecules.
