The present invention discloses a flexible display panel, a flexible display device and a method of manufacturing the flexible display panel, the metal patterns of the bent region of the flexible display panel of the present invention has a double-layer structure, and the second metal layer pattern is designed with a wavy pattern, which can reduce the stress on the metal layer patterns during pad bending process, decrease the breakage probability of metal layer patterns in the bent region of the flexible display, and ensure the resistance stability of the metal layer patterns. Furthermore, the connection portion between the first metal layer pattern and the second metal layer pattern can improve the reliability, reduce the abnormal probability of display caused by the pattern breakage, and ensure normal signal transmission.
