Abstract:
1. A multi-domain vertical alignment (MVA) liquid crystal display (LCD), comprising: a first substrate and a second substrate; a common electrode formed on one surface of the first substrate; a plurality of pixel electrodes formed on a surface of the second substrate and being opposite to the common electrode, each of the pixel electrodes including a slit and a first sub-pixel electrode and a second sub-pixel electrode which are electrically isolated to each other by the slit; a plurality of first switches and second switches, wherein each of the first switches is used for controlling corresponding first sub-pixel electrode, and each of the second switches is used for controlling corresponding second sub-pixel electrode; and liquid crystals (LCs) sealed between the first substrate and the second substrate; wherein by the strong electrical force corresponding to the fringe electrical field between the first and second sub-pixel electrodes, the first and second sub-pixel electrodes of one of the pixel electrodes incline the liquid crystals to different directions in the close proximity of the slit so as to create at least two domains when data signals of opposite polarities with respect to the voltage of the common electrode are respectively applied to the first sub-pixel electrode and the second sub-pixel electrode of the one of the pixel electrodes; wherein each pixel electrode corresponds to a pixel, each first sub-pixel electrode corresponds to a first sub-pixel and each second sub-pixel electrode corresponds to a second sub-pixel.
