A GOA driving circuit includes a plurality of cascaded GOA units and outputs a gate driving signal to an Nth-stage horizontal scanning line of a display region by an Nth-stage GOA unit. The Nth-stage GOA unit includes a pull-up unit, a pull-up control unit, a pull-down unit, a pull-down sustaining unit, a download unit, and a bootstrap capacitor unit. The pull-up unit, the pull-down unit, the pull-down sustaining unit, and the bootstrap capacitor unit are respectively electrically connected with a first node and an Nth-stage horizontal scanning line. The pull-up control unit and the download unit are electrically connected with the first node. N is a positive integer. The Nth-stage GOA unit further includes a forced pull-down unit, which is used to force the first node to low level when clock signals are disappeared. A LCD device is also provided.
A gate driver on array (GOA) driving circuit, wherein the GOA driving circuit comprises a plurality of cascaded GOA units and outputs a gate driving signal to an Nth-stage horizontal scanning line of a display region by an Nth-stage GOA unit, the Nth-stage GOA unit comprises a pull-up unit, a pull-up control unit, a pull-down unit, a pull-down sustaining unit, a download unit, and a bootstrap capacitor unit;
A liquid crystal display (LCD) device, which comprises a gate driver on array (GOA) driving circuit, wherein the GOA driving circuit comprises a plurality of cascaded GOA units and outputs a gate driving signal to an Nth-stage horizontal scanning line of a display region by an Nth-stage GOA unit, the Nth-stage GOA unit comprises a pull-up unit, a pull-up control unit, a pull-down unit, a pull-down sustaining unit, a download unit, and a bootstrap capacitor unit;
