Abstract
A liquid crystal display (LCD) device includes at least three electrodes disposed between a liquid crystal layer and two substrates in each pixel area with at least one electrode between the liquid crystal layer and each of the two substrates. Each pixel area has at least two sub-pixel areas applied with different electrode voltages. One of the electrodes is applied with a DC voltage. Two of the electrodes are applied respectively with first and second AC voltages synchronous with an LCD timing signal. Both first and second AC voltages have a high-level period and a low-level period equal to the high-level period. The timing period of the LCD timing signal is at least one or more times of the high-level periods of the two AC voltages with the high-level period of the first AC voltage longer than the high-level period of the second AC voltage.
