The present disclosure discloses a flexible display panel including a device layer, an organic planarization layer formed on the device layer, a light-emitting unit formed on the planarization layer, and an anode layer of the light-emitting unit adjacent contacted to the organic planarization layer. The organic planarization layer includes at least one first connection hole and at least one second connection hole; an output end of the device layer is connected with the anode layer through the first connection hole; the second connection hole has a depth smaller than the thickness of the organic planarization layer, and the anode layer of the light-emitting unit is further connected to the organic planarization layer through the second connection hole. The flexible display panel can protect the anode layer of the flexible display device from cracking due to poor flexibility during the bending process and improve the quality of the flexible display device.
