摘要： A liquid crystal display (LCD) device and a driving method can produce reduced direct current image sticking and flicker. An LCD panel for the LCD device has liquid crystal cells having a common same color in each horizontal line and has columns of liquid crystal cells having a repeating sequence of color, a timing controller for generating a polarity control signal such that the polarity control signal is varied at intervals of one frame period, a data driving circuit supplying data voltages to the data lines in response to the polarity control signal, and a gate driving circuit supplying scan pulses to the gate lines. The liquid crystal cells include first liquid crystal cell groups supplied with data voltages having polarities inverted from polarities the previous frame period, and second liquid crystal cell groups supplied with data voltages having polarities identical to the polarities supplied in the previous frame period.
