Abstract: A flexible display panel includes a flexible glass substrate and a display module disposed on the flexible glass substrate. The flexible glass substrate is used as a support structure, and a first bending structure is disposed on each of two opposite edges of the flexible glass substrate. The flexible display panel forms an arc-shaped display panel when the display module is supported. In addition, the flexible display panel further includes an encapsulation layer, where the encapsulation layer encapsulates the display module on the flexible glass substrate. For the flexible display panel, the flexible glass substrate is used to carry the display module, thereby improving transparency of the entire flexible display panel.
