1. A display device, comprising a module stack defined with two non-bending areas and a bending area located between the two non-bending areas, wherein the bending area comprises two first bending areas and a second bending area located between the two first bending areas, wherein a bending center line is defined in the second bending area;
wherein the module stack comprises:
a backplate;
a flexible display panel disposed on a side of the backplate; and
a support layer disposed on a side of the backplate away from the flexible display panel;
wherein the support layer comprises:
a first support structure disposed on the side of the backplate away from the flexible display panel and located in the two non-bending areas, the two first bending areas, and the second bending area, wherein a thickness of the first support structure is uniform and no groove is defined in the first support structure;
two second support structures disposed on a side of the first support structure away from the flexible display panel, located in the two non-bending areas and the two first bending areas, and are axially symmetric about the bending center line, wherein single or a plurality of grooves are defined on a side of any of the two second support structures located in the two first bending areas away from the flexible display panel; and
wherein the thickness of the portion of any of the two second support structures in the two non-bending areas is greater than the thickness of the first support structure and the thickness of the second support structure between any two adjacent grooves is greater than the thickness of the first support structure.
