Zusammenfassung:	An apparatus and a method for driving an LCD device are provided to prevent degradation of image quality by maintaining a constant data charge period even when a frame frequency is varied. An apparatus for driving an LCD(Liquid Crystal Display) device includes a liquid crystal panel(12), a data driver(14), a gate driver(16), and a timing controller(18). The liquid crystal panel includes liquid crystal cells, which are formed on regions defined by data and gate lines(DL1~DLm,GL1~GLn). The data driver supplies image signal to the data lines. The gate driver supplies scan pulse to the gate lines. The timing controller generates data control signals(SSP,SSC,POL) including a source output enable signal(SOE) whose width is varied according to a frame frequency to control the data driver, and generates a gate control signal to control the gate driver.
