A pixel driving circuit, a pixel array, a driving method and an organic light emitting display panel are provided. The pixel driving circuit includes: a first transistor, a second transistor, a third transistor, a fourth transistor, a fifth transistor, a sixth transistor, a seventh transistor and a first capacitor. The sixth transistor is configured to transmit a signal with a first potential to a light emitting element in response to a second scanning line signal. The seventh transistor is configured to transmit a signal with a second potential to a gate of the second transistor in response to the second scanning line signal, and the second potential is greater than the first potential.
