A flexible display panel is provided, defining a display area, a bonding area, and a border area, and including a flexible substrate, a protective layer, a semiconductor layer, and a touch layer. A gate lead trace, a ground trace, a touch sensor receiving electrode lead trace, and a display area pad are disposed on the flexible substrate corresponding to the display area. The protective layer corresponding to the border area is provided with a first through hole, and the gate lead trace is electrically connected to a gate of the semiconductor layer through the first through hole. The disclosure has advantages of changing a traditional trace position, adopting a hidden trace design, and designing the trace in the same position as the display area, so that no additional space is occupied, and a non-display area is reduced, thereby effectively reducing a trace width in an edge of a panel.
