Abstract
A multi-domain vertical alignment liquid crystal display device includes a data line, a first gate line, a second gate line, a first sub-pixel unit, and a second sub-pixel unit. The first sub-pixel unit includes a first switch, a first liquid-crystal capacitor and a first storage capacitor. The first switch functions to control writing the data signal of the data line into the first liquid-crystal and storage capacitors based on the first gate signal of the first gate line. The second sub-pixel unit includes a second switch, a second liquid-crystal capacitor, an auxiliary switch, a second storage capacitor and a third storage capacitor. The second and auxiliary switches are employed to control writing the data signal into the second liquid-crystal capacitor, the second storage capacitor and the third storage capacitor based on the first gate signal and the second gate signal of the second gate line respectively.
