Abstract: The present disclosure provides a pixel driving circuit and a display panel, including a data transistor connected to a data line, a driving transistor connected in series with a light emitting element between a first power supply line and a second power supply line, and a boost module of which an input terminal is loaded with a boost input signal. A source and a gate of the driving transistor are respectively electrically connected to the light emitting element and the data transistor, and an output terminal of the boost module is electrically connected to the gate of the driving transistor to enable the voltage of the gate of the driving transistor to boost from a first voltage to a second voltage.
