Abstract
A gate driver on array (GOA) device and a display panel are proposed. In the present application, by adding a twenty-first transistor and a first control clock terminal electrically connected to the twenty-first transistor in a forward-reverse scan module to control potentials of a first node and a third node, a leakage of the first node during operation can be reduced, thereby improving reliability of the GOA device.
