The supporting back plate comprises a first supporting plate (200) and a second supporting plate (400) hinged to the first supporting plate (200) by means of a rotation shaft system device (300). A tension release mechanism is provided at the first supporting plate (200) or the second supporting plate (400). The flexible display screen (100) has a first end (101) connected to the first supporting plate or the second supporting plate (400) and a second end (110) opposite to the first end (101) and connected to the tension release mechanism, such that said end is slidable along the corresponding supporting plates between a first position at which the foldable display device (1) is in an outwardly bent state and a second position at which the foldable display device (1) is in an unfolded state, and between the second position and a third position at which the foldable display device (1) is in an inwardly bent state.
