摘要

The present invention provides 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, wherein a DC image sticking and a flicker are sufficiently reduced, and a liquid crystal display device driven by using the liquid-crystal-driving method. The present invention relates to a method of driving liquid crystal by causing a potential difference between a pair of electrodes provided for one of upper and lower substrates. In the liquid-crystal-driving method, a driving operation of driving liquid crystal by causing a potential between a pair of electrodes is executed. In the driving operation, the absolute value of a second offset voltage is larger than that of a first offset voltage.

1. 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, comprising:
changing an application voltage to one of the pair of electrodes in accordance with a gray scale; inverting polarity of the application voltage to each of the pair of electrodes; providing a planar electrode for one and/or the other one of the upper and lower substrates; and executing a driving operation, 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 the 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, in which an absolute value of the second offset voltage is larger than that of the first offset voltage.
