1. A display panel, comprising:
a flexible screen, the flexible screen comprising a straight section, a bending section, and a bonding section that are sequentially connected;
an adhesive layer, the adhesive layer disposed on a backlight side of the flexible screen, and the adhesive layer correspondingly disposed in the straight section of the flexible screen;
a first heat dissipation layer, the first heat dissipation layer disposed on one side of the adhesive layer away from the flexible screen;
a support layer, the support layer disposed on one side of the first heat dissipation layer away from the adhesive layer; and
a second heat dissipation layer, wherein one side of the second heat dissipation layer is bonded to the support layer, and another side of the second heat dissipation layer is electrically connected to a back side of the flexible screen corresponding to the bonding section;
wherein the support layer and the second heat dissipation layer are disposed on one side close to the bending section, both the first heat dissipation layer and the second heat dissipation layer are disposed as metal heat dissipation layers, metal particles are disposed in the metal heat dissipation layers, and a gap is formed between adjacent metal particles.
