Abstract

The invention provides a folding display device. The folding display device comprises a display panel and a supporting plate used for supporting the display panel, wherein the display panel comprisesa flexible display area, a bending area corresponding to the flexible display area is arranged on the supporting plate, and an extensible hollowed-out structure is arranged in the bending area. According to the folding display device, through the arrangement of the hollow structure, the deformation capacity and the extension capacity of the bending area are improved, compared with the prior art, the extrusion acting force borne by the display panel in the bending and flattening process of the folding display device is reduced, and the risk of interlayer stripping or cracking is reduced, meanwhile, the integrated supporting plate improves flatness of the display panel and reduces the overall thickness of the display device.
