A driving circuit of a liquid crystal display device includes gate and data lines, a thin film transistor connected to the gate and data lines, and a liquid crystal capacitor connected to the thin film transistor. The driving circuit includes a gate driving unit for generating a gate signal applied to the gate line, a source driving unit for generating a data signal applied to the data line, a gamma power source unit for applying a gamma reference voltage to the source driving unit, a common voltage unit for applying a common voltage to the liquid crystal capacitor, a discharging signal unit for generating a discharging enable signal when a power of the liquid crystal display device is off, and a multiplexer, connected to the common voltage unit and the gamma power source unit, for selectively applying a voltage to the source driving unit according to the discharging enable signal.
