Abstract: Provided are a pixel circuit, a display apparatus and a driving method. In one type of pixel circuit, a first switch transistor is arranged between a gate electrode of a driving transistor and a second electrode of a first reset transistor, such that a leak current of the first reset transistor has a relatively small influence on a gate signal of the driving transistor. In other types of pixel circuit, a second reset transistor for short-circuiting the gate electrode and a first electrode is provided, such that the resetting of an anode of a light-emitting device is only related to a signal of a second reset signal end. Therefore, the voltage difference between two ends of a third reset transistor can be reduced by means of adjusting a signal voltage of a reference voltage signal end.
