A flexible display device is disclosed. The flexible display device includes a flexible display screen and at least two supporting plates configured to fix the flexible display screen, wherein one supporting plate of the at least two supporting plates is rotatable relative to the other supporting plate until they are overlap each other, and the flexible display device further comprises: a guide component disposed between the two supporting plates and configured to prevent a bending portion of the flexible display from being squeezed by the two adjacent supporting plates. When the flexible display is folded, the bending portion thereof can be held in a space supported by the guide component and the two supporting plates, thereby preventing the problem of wrinkles of the flexible display screen and extending the life time.
