A liquid crystal display device and a driving method thereof are provided to remove a flicker of an image or a black screen by generating a vertical enable signal. A liquid crystal display device includes a liquid crystal panel, a gate driver, a data driver, and a timing controller. The gate driver and the data driver supply a gate signal and a data signal to the liquid crystal panel. The timing controller includes an LVDS(Low Voltage Differential Signaling) receiving part(110) and a logic part(120). The LVDS receiving part is connected to an external LVDS transmitting part, and has a phase locked loop(112). The logic part includes a vertical enable signal generating part(121), a fail safe part(123), a gate control signal generating part(125), a data control signal generating part(127), and a data processing part(129). The gate control signal generating part receives an image signal, a synchronous signal, a data enable signal, and a clock signal, and controls the gate driver. The data control signal generating part controls the data driver. The data processing part supplies the image signal to the data driver. The fail safe part determines whether an inputted signal is normal or not. The vertical enable signal generating part generates a vertical enable signal according to a data enable signal, and controls the fail safe part, the gate control signal generating part, and the data control signal generating part.
