Abstract: A display device having a plurality of gate lines and a gate drive circuit is disclosed. The gate drive circuit includes a pull-up transistor configured to receive a first clock signal and to charge an output node to a voltage of the first clock signal based on a voltage of a Q node. The output node is connected to a corresponding one of the gate lines. The gate drive circuit also includes a switching circuit configured to charge the Q node based on a second clock signal. The switching circuit has an inverter circuit configured to control the voltage of the Q node based on the second clock signal.
