A multi-linkage hinge includes a base bar, two friction bars, two synchronous rotation bars and two torsion plates. The base bar extends longitudinally to have two connecting ends and two middle pivot portions . Each friction bar has two link ends respectively coupled to the connecting end of the base bar and a middle portion of the respective torsion plate. The synchronous rotation bars are interposed between the friction bars, and each has two pivot ends respectively coupled to the middle pivot portion of the base bar and a driven end of the respective torsion plate. The torsion plates are turnable synchronously relative to the base bar between unfolded and folded positions. In the unfolded position, a bending space is formed between the torsion plates for receiving a bending portion of the display sheet.
