Flexible display device

The invention relates to a flexible display device which comprises a flexible display module, the flexible display module comprises a flexible functional layer, the flexible functional layer comprises a first functional area and a second functional area which are adjacently arranged in the sliding and rolling direction, the orthographic projection of a flexible display substrate on the flexible functional layer is located in the first functional area, and the orthographic projection of the flexible display substrate on the second functional area is located in the second functional area. The switching structure is arranged on the face, close to or away from the flexible display substrate, of the flexible functional layer, and the orthographic projection of the switching structure on the flexible functional layer is located in the second functional area. According to the flexible display panel, the acting force is applied to the switching structure connected with the flexible functional layer, so that the tensi
