1. A flexible display device, comprising:
a rolling assembly and a flexible display module at least partially wound in the rolling assembly;
wherein the rolling assembly comprises a shaft and at least a shell layer coaxially arranged from an inside to an outside of the rolling assembly, the shaft and the at least a shell layer are coupled to each other and collectively allow for formation of a cross-sectional curve based on a characteristic of an Archimedes spiral, and the flexible display module comprises a first end fixedly connected to the shaft by an adhesive;
wherein the flexible display module is configured to drive the rolling assembly to rotate in a direction of releasing the flexible display module from a retracted state along with a process of expanding the flexible display module, enabling a linked state of the shell layer and the shaft to be released; and
wherein the rolling assembly is configured to rotate in a direction of retracting the flexible display module along with a process of retracting the flexible display module, enabling the shell layer and the shaft to return to the linked state.
