Claim 13:
14. A display device, comprising a display module, wherein the display module comprises a display panel and a heat dissipation structure; wherein
the display panel comprises a substrate and a display substrate layer disposed on the substrate, and the heat dissipation structure is disposed on a side, distal from the display substrate layer, of the substrate; and
a gap is formed between at least a partial region of the heat dissipation structure and the substrate;
the heat dissipation structure comprises at least one protruding structure, wherein the gap is formed between each protruding structure and the substrate, and the protruding structure is protruded away from the substrate; and
the heat dissipation structure further comprises at least one transition structure, wherein the transition structure is connected to the protruding structure and comprises a recessed structure recessed toward the substrate, a maximum distance between the protruding structure and the recessed structure in a first direction ranges from 0.1 mm to 0.2 mm, the first direction being perpendicular to a surface, distal from the display substrate layer, of the substrate;
wherein the recessed structure comprises a second curved surface structure;
wherein in the case that the protruding structure comprises a first curved surface structure, a boundary of the first curved surface structure on a first section is in a first arc, and a boundary of the second curved surface structure on the first section is in a second arc, a radius of the first arc being equal to a radius of the second arc, the first section being perpendicular to a surface, distal from the display substrate layer, of the substrate.
