Abstract: In a method of driving a liquid crystal panel, an overshoot signal is applied to the liquid crystal panel to display images on the liquid crystal panel. An overshoot level C is selected from a plurality of overshoot levels Dn. In this selecting, difference values between momentary values of a response waveform gn and momentary values of an ideal waveform f are obtained and added for a predetermined period and a minimum first error value E1 is obtained. One of the overshoot levels Dn corresponding to the response waveform gn having the minimum first error value E1 is selected as the overshoot level C. One of the overshoot levels Dn is selected by using an average value from the values obtained for the predetermined period similarly to humans' recognition of the liquid crystal display element. Accordingly, tailing or an image failure is less likely to occur.
