1. A flexible display panel, comprising:
a flexible display panel body; and
a support layer disposed on a side of the flexible display panel body and comprising a first bendable portion and a second bendable portion that are adjacent to each other, wherein the first bendable portion comprises a first bendable sub-portion and a second bendable sub-portion that are sequentially away from the second bendable portion, the second bendable portion comprises a third bendable sub-portion and a fourth bendable sub-portion that are sequentially away from the first bendable portion, and the first bendable sub-portion, the second bendable sub-portion, the third bendable sub-portion, and the fourth bendable sub-portion are all provided with openings;
wherein when the flexible display panel body is in a first folded state, the flexible display panel body comprises a first flexible portion that is folded, and a second portion and a third portion located on opposite sides of the first flexible portion, the first bendable sub-portion and the third bendable sub-portion are disposed opposite to each other and respectively support opposite sides of the first flexible portion, and the second bendable sub-portion and the fourth bendable sub-portion are disposed opposite to each other and respectively support the second portion and the third portion;
when the flexible display panel body is in a second folded state, the flexible display panel body comprises a second flexible portion that is folded, the first bendable sub-portion and the second bendable sub-portion support a side of the second flexible portion, and the third bendable sub-portion and the fourth bendable sub-portion support an opposite side of the second flexible portion; and
a bending direction of the second flexible portion is opposite to a bending direction of the first flexible portion, and the first flexible portion is located within a boundary of the second flexible portion;
wherein the flexible display panel further comprises:
a housing comprising a first housing and a second housing; and
a hinge disposed in the housing, connected to the first housing and the second housing, and comprising:
a bending portion;
a first support portion disposed on a side of the bending portion and corresponding to the first housing, wherein a side of the first support portion is rotatably connected to the side of the bending portion, and an opposite side of the first support portion is slidably connected to the first housing; and
a second support portion disposed on an opposite side of the bending portion and corresponding to the second housing, wherein a side of the second support portion is rotatably connected to the opposite side of the bending portion, and an opposite side of the second support portion is slidably connected to the second housing;
wherein the flexible display panel body is disposed in the housing and disposed on sides of the first housing, the second housing, and the hinge, and the support layer is disposed between the flexible display panel body and the hinge.
