Abstract: A pixel driving circuit proposed in the present application includes a first transistor, a second transistor, a third transistor, a fourth transistor, a fifth transistor, a sixth transistor, a capacitor and a light-emitting device. In the pixel driving circuit, a threshold-voltage compensation is performed on the first transistor, and this can efficiently improve attenuation of electric current of the light-emitting device caused by a drift of threshold voltage of a drive transistor, thereby improving stability of a display panel.
