Abstract:
A gate driver on array (GOA) circuit for a liquid crystal display is disclosed. The GOA circuit includes multiple cascaded GOA units, and a Nth stage GOA unit controls a charging of a Nth stage horizontal scanning line of a display area. The Nth stage GOA unit includes a pull-up circuit, a pull-down circuit, a first pull-down holding circuit, a second pull-down holding circuit, a pull-up control circuit, a transfer circuit, and a boast capacitor. The present invention also discloses a liquid crystal display (LCD) device. The present invention can decrease the cost of the LCD device, improve the functionality of the GOA circuit, and increase the operation life.
