In this embodiment, the support plate 142 includes a first support plate 142 a and a second support plate 142 b , and the first support plate 142 a and the second support plate 142 b are connected to opposite sides of the elastic bending portion 144 .

Wherein, in one embodiment, the first support plate 142a, the second support plate 142b and the elastic bending portion 144 may be a steel sheet with an integral structure, and the elastic bending portion 144 is formed by etching to form a plurality of elastic ribs 146, and a plurality of elastic bars 146 are formed. There are spaces between the elastic ribs 146 . When the support assembly 14 is subjected to lateral tension, the intervals between the plurality of elastic ribs 146 can expand to both sides, so that the elastic bending portion 144 is stretched; that is, when the support structure 10 is attached to the flexible display panel When the bottom surface of the flexible display panel 20 is in a folded state, the elastic bending portion 144 can be stretched to meet the needs of the flexible display panel 20 covering the inner side of the flexible display panel 20 more gently, so as to avoid severe extrusion of the flexible display panel 20.
