Abstract
A shift register unit includes a shift circuit having first, second, and third power supply signal terminals respectively coupled to first, second, and third power supply lines configured respectively to transmit first, second, and third power supply signals; and configured to respond to the first or second power supply signal and output the signal from a first node to an output terminal; a signal generating circuit respectively coupled to the first and second power supply lines and the first node, and configured to output the second power supply signal to the first node when an electric potential of the first power supply signal is an effective potential, and output the first power supply signal to the first node when the electric potential of the second power supply signal is an effective potential, wherein the electric potentials of the first and second power supply signals are complementary to each other.
