An liquid crystal display (LCD) device includes an LCD panel provided with a plurality of pixels, wherein the pixels are defined by a plurality of gate and data lines formed perpendicularly, an auxiliary storage capacitor formed in each of the pixels, a gate driver to drive the gate lines in sequence by supplying a scan pulse voltage to the gate lines of the LCD panel, wherein the scan pulse voltage is comprised of a high gate voltage and a low gate voltage, and a discharger to supply a pulse voltage to the gate line based on a source voltage for operating the LCD panel, wherein the discharger enables the auxiliary storage capacitor to be discharged to the ground voltage as the voltage of the gate line approaches the ground voltage.
