摘要： The present invention provides a liquid crystal driving method of sufficiently reducing DC image sticking together with flicker and a liquid crystal display device driven by using the liquid crystal driving method. The invention relates to a liquid crystal driving method of driving liquid crystal by causing a potential difference between a pair of electrodes provided for one of upper and lower substrates. Polarity of each of application voltages to the pair of electrodes is inverted, and a planar electrode is provided for the upper substrate and/or the lower substrate. When a difference obtained by subtracting a voltage applied to the planar electrode from an average value of a positive voltage and a negative voltage applied to one of the pair of electrodes is set as a first offset voltage and a difference obtained by subtracting a voltage applied to the planar electrode from an average value of a positive voltage and a negative voltage applied to the other one of the pair of electrodes is set as a second offset voltage, a driving operation that the values of the first and second offset voltages are switched with each other is executed.
