Abstract
Embodiments of the invention provide a pixel driving circuit and a display device, and the pixel driving circuit includes a drive transistor and an organic light emitting diode, where a cathode of the organic light emitting diode receives a first power supply signal, and an anode of the organic light emitting diode is connected with a gate electrode of the drive transistor; the first power supply signal is loaded to the gate electrode of the drive transistor through the cathode and the anode of the organic light emitting diode to reset a signal at the gate electrode of the drive transistor during an operating period of the pixel driving circuit; and the first power supply signal is a low-level signal.
