Abstract
The present application provides a GOA device and a gate driving circuit. The GOA device includes a pull-up control circuit, a bootstrap capacitor, a pull-up circuit, a pull-down circuit, and a pull-down holding circuit. The present application decreases a number of TFTs of the gate driving circuit and simplifies a structure of the gate driving circuit by multiplexing the bootstrap capacitor, the pull-down circuit, and the pull-down holding circuit.
