In a multi-domain vertical alignment liquid crystal display wherein a pixel that has two sub-pixels, an additional switching element is used to achieve a voltage differential between the electrode voltage potential in one sub-pixel and the other during and after the charge-sharing period. The electrodes in the sub-pixels are connected to each other through a charge-sharing capacitor and a controlling switching element, such as another transistor. Before the charge-sharing period, the controlling switching element is operated in a non-conducting state and the voltage potentials of the sub-pixel electrodes are substantially equal. During the charge-sharing period, the controlling switching element is operated in a conducting state to facilitate charge-sharing. The additional switching element is used to achieve the voltage differential more effectively and without additional capacitors.

A liquid crystal display and a driving method thereof. A gate driver drives a first pixel of the display via a first scanning line within a frame period including first and second data writing intervals. A first data voltage and a second data voltage are transmitted to the first pixel in the first and second data writing intervals, respectively. After the first data writing interval, a first color light source illuminates the first pixel. After the second data writing interval, a second color light source illuminates the first pixel. In a reset interval between the first and second data writing intervals, a voltage of a common line coupled to a storage capacitor of the first pixel is changed from a first common voltage to a second common voltage so that a voltage of a first liquid crystal capacitor of the first pixel is changed.
