PURPOSE: A liquid crystal display and a driving method thereof are provided to reduce the power consumption of a data driving unit by supplying dummy image data and a polarity control signal to the data driving unit in a blank period of a data enable signal. CONSTITUTION: A dummy signal generating unit(10) generates a dummy data enable signal by extending a data enable signal in a blank period. A selecting unit(14) selects and outputs the data enable signal or the dummy data enable signal. A gate control unit(20) generates a plurality of gate control signals. A data control unit(18) generates a plurality of data control signals. An image aligning unit(16) aligns image data according to the resolution of a liquid crystal panel and supplies the aligned image data to the data driving unit.
