Abstract
A multi-domain vertical alignment liquid crystal display that does not require physical features on the substrate (such as protrusions and ITO slits) is disclosed. Each pixel of the MVA LCD is subdivided into color components, which are further divided into color dots. The color components include polarized extension regions that extend between color dots of neighboring color components (and neighboring pixels). The voltage polarity of the color dots and polarized extension regions are arranged so that fringe fields in each color dot causes multiple liquid crystal domains in each color dot. Specifically, the color dots and polarity extension regions of the display are arranged so that neighboring polarized elements have opposite polarities.
