A pixel circuit and a driving method therefor, and a display device. The pixel circuit comprises a driving sub-circuit, a writing sub-circuit, a compensation sub-circuit, a reset sub-circuit, a first light-emitting control sub-circuit, a second light-emitting control sub-circuit, an electric leakage prevention sub-circuit, a storage sub-circuit, and a light-emitting element, wherein the reset sub-circuit is configured to reset a fourth node (N4) under the control of a signal of a light-emitting control signal terminal (EM), and reset a fifth node (N5) under the control of a signal of a reset control signal terminal (Re); the compensation sub-circuit is configured to compensate for threshold voltage of the driving sub-circuit to the fifth node (N5) under the control of a signal of a first scanning signal terminal (Gate); the electric leakage prevention sub-circuit is configured to write a signal of the fifth node (N5) to a first node (N1) under the control of a signal of a second scanning signal terminal (Gate_N).
