A driving method for a liquid crystal display device and an over-drive correction device, which can perform proper overdrive control in various operating environments. The over-drive correction device includes a dummy liquid crystal unit embedded in the liquid crystal display device, a liquid crystal capacitive sensor to detect a capacitance (dielectric constant) of the dummy liquid crystal unit, a calculation circuit for lookup tables, an overdrive lookup table, a prediction lookup table and an overdrive circuit. The calculation circuit for lookup tables corrects data in the over-drive lookup table and the prediction lookup table according to the detection result generated from the liquid crystal capacitive sensor. The over-drive circuit performs over-drive control in the liquid crystal display device based on the newly corrected over-drive lookup table and prediction lookup table.
