Abstract

A pixel driving circuit and a display device are provided. The pixel driving circuit is configured to drive a pixel unit to operate, and the pixel driving circuit includes a first compensation sub-circuit and a second compensation sub-circuit. The first compensation sub-circuit is configured to compensate a voltage of an anode of the pixel unit according to a reference signal and a data signal, and the second compensation sub-circuit is configured to compensate a leakage current generated by at least one transistor in the first compensation sub-circuit according to a leakage current generated by the second compensation sub-circuit.
