The present application discloses a flexible display panel and a method for fabricating thereof, and a flexible display apparatus. The flexible display panel including at least two non-bending regions and a bending region disposed between the at least two non-bending regions, at least one of the at least two non-bending regions is used as a display region; both the non-bending region and the bending region include the flexible substrate and the organic light emitting device layer, wherein the display region is further provided with at least one metal layer for providing a driving signal to the organic light emitting device layer, and the bending region is further provided with a buffer layer. When meeting the demand of display image in the bending region, the probability of damaging to the metal traces influenced by the bending in the bending region is reduced to increase the life time of the display panel.
