The present disclosure provides a flexible display panel including a display area and a non-display area, and a bending area is arranged therebetween. The flexible display panel further includes a flexible substrate and a thin film transistor layer. The thin film transistor layer includes a semi-conductor layer, a gate electrode insulation layer, a gate electrode layer, an insulation interlayer and a source-drain electrode metal layer. The flexible display panel includes a touch layer arranged on one side of the thin film transistor layer away from the flexible substrate. The touch layer includes a first and second touch metal layer. The flexible display panel further includes signal transmission lines including at least two parallel wiring layers in the bending area. Each wiring layer is fabricated in a same layer with at least two of the source-drain electrode metal layer, the first touch metal layer, and the second touch metal layer.
