The present invention provides a pixel driving circuit, a display device and a pixel driving method. In the pixel driving circuit, the control unit is connected with the data line, a first control line, a second control line, a first gate line and a second gate line; the first charging unit and the second charging unit are both connected with the control unit; a first electrode of the light emitting device is connected with the control unit and the second charging unit, and a second electrode of the light emitting device is connected with the second power supply terminal. According to the present invention, by providing two storage capacitors and improving the pre-charging manner, the gate of the driving transistor is provided with the data voltage lower than the operating voltage. The threshold voltage is stored into the first capacitor, thus the threshold voltage compensation is implemented.
