An LCD(Liquid Crystal Display) device and a driving circuit thereof are provided to supply a control signal having the same pulse width to an LCD panel even though the LCD is connected to any external system providing different clock signals, thereby reducing image quality deviation due to the control signal. An external clock signal generator(110) generates and outputs a first clock signal. A timing controller(120) receives the first clock signal, receives video data, data enable signals, vertical and horizontal synchronous signals and a second clock signal from an external system, and generates a control signal where a pulse width is decided using the first clock signal and the vertical synchronous signal before outputting the generated control signal. |
