PROBLEM TO BE SOLVED: To provide a liquid crystal display device and a driving method of the device capable of effectively improving such a phenomenon that images of previous frames remain. SOLUTION: The liquid crystal display device includes a data driver, a common voltage generating circuit, a plurality of data lines, a plurality of pixel electrodes and a common electrode. The data driver supplies a data voltage to the plurality of pixel electrodes through the plurality of data lines. The common voltage generating circuit supplies a common voltage to the common electrode, wherein in one frame, the common voltage is formed as superposition of a main common voltage with alternating polarities and an auxiliary voltage with periodic changes, and an absolute value of the common voltage changes slightly from each frame to the next adjacent frame.
