1. A flexible display device, comprising:
a flexible display screen having a bendable region;
a housing around the flexible display screen; and
a support layer having ductility between the housing and a back side of the flexible display screen,
wherein the support layer is at least partially in the bendable region of the flexible display screen, and
the housing has a bendable region corresponding to the bendable region of the flexible display screen, the support layer comprises a first metal layer and a second metal layer, the first metal layer is on the back side of the flexible display screen, the second metal layer is on a side of the first metal layer close to the housing and on both sides of the bendable region of the housing,
wherein a main structure of the housing comprises a first portion and a second portion on two sides of the bendable region of the housing, and the bendable region between the first portion and the second portion is provided with a rotating shaft configured to allow the first portion and the second portion to rotate relatively to make the housing bent,
wherein a first accommodating space and a second accommodating space are between the second metal layer on the two sides of the bendable region of the housing and an inner surface of the housing, respectively,
the first accommodating space is provided with a circuit board, and at least one of an upper side and a lower side of the circuit board is provided with a chip; and the second accommodating space is provided with a battery, and
the second metal layer is coupled to the circuit board,
wherein the circuit board is provided with a through hole, the second metal layer is provided with an opening, and a connector is in the through hole and the opening so as to couple the second metal layer to the circuit board, and
wherein the second metal layer has a protrusion portion on a side of the second metal layer close to the circuit board, and the opening is in the protrusion portion.
