The present invention provides a pixel circuit, a display substrate and a display device. The pixel circuit comprises a control section, a light emitting diode, a high-level input terminal, a low-level input terminal and a reference terminal, in which the control section comprises a driving thin film transistor, at least one capacitors and a plurality of switching thin film transistors. The reference terminal is connected with the low-level input terminal so as to discharge a capacitor which is connected with a gate of the driving thin film transistor in a pixel resetting stage of the pixel circuit.
