The driving method comprises the following steps. First the scan driving circuit provides a plurality of scan signals to the plurality of scan electrodes of the plurality of scan groups, respectively. Each scan signal includes at least a select signal, at least a non-select signal, at least a select cycle, and at least a non-select cycle. The select signal is located in the select cycle, while the non-select signal, the non-select cycle. When an Nth scan electrode is located in the select cycle, an (N−1)th or (N+1)th scan electrode of the plurality of scan electrodes is located in the non-select cycle. Then, the data driving circuit provides a data signal to each of the data electrodes according to a plurality of display data for driving the LCD device to display an image by using the plurality of scan signals and the plurality of data signals. Thereby, the imbalance wire coupling effect among scan electrodes can be eliminated and thus improving the display efficiency of the LCD device.
