A flexible display panel includes a flexible substrate, a blocking layer, a buffering layer, an active layer, a first gate electrode insulating layer, a gate electrode metal layer, a second gate electrode insulating layer, a first source/drain electrode metal layer, an interlayer insulating layer, a first passivation layer, a second source/drain electrode metal layer, a second passivation layer, an anode metal layer, a pixel isolation layer, and a pixel support layer. The second source/drain electrode metal layer is connected to the active layer and the first source/drain electrode metal layer via two through holes.
