PROBLEM TO BE SOLVED: To realize a quick response characteristic of liquid crystal by adopting a charge shared driving method. SOLUTION: A liquid crystal display device comprises a data storage means for storing current input data and outputting the stored current input data as previous input data, a lookup table for storing corrected current input data and corrected previous input data which respectively correspond to the current input data and the previous input data, a control means for generating 1st and 2nd loading signals, storing the current input data in the data storage means, reading out the previous input data from the data storage means, converting the current input data and the previous input data into the corrected current input data and the corrected previous input data by referring to the lookup table, calculating a mean value on the basis of the corrected current input data and the corrected previous input data, substituting a value approximated to original gradation data for the calculated mean value, and outputting the substituted value as free charge data, and a liquid crystal driving means for converting the free charge data into an analog signal and generating a liquid crystal driving signal on the basis of the converted analog signal in response to the 1st and 2nd loading signals.
