The invention relates to a liquid crystal display (LCD) device, a driving circuit thereof and a driving method. The driving circuit comprises a plurality of scanning lines, a plurality of data lines which vertically intersect with the scanning lines in an insulated way, a plurality of pixel units defined by the scanning lines and the data lines, a scan driver circuit used for driving the scanning lines and a data driver circuit used for driving the data lines, a sequence control circuit, a benchmark voltage control circuit and a comparer. The comparer compares pulse signal voltage input to the scan driver circuit with the benchmark voltage output by the benchmark voltage control circuit and inputs comparing result to the sequence control circuit; the sequence control circuit outputs an enabling signal which controls output according to the comparing result so as to control the scan driver circuit to output the scan signal. The LCD device of the invention effectively overcomes the problem of flickering display pictures of the LCD device when the scan signals switch among different scanning lines.
