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. Each pixel also contains fringe field amplifying regions that separate the color dots of a pixel. The voltage polarity of the color dots and fringe field amplifying 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 fringe field amplifying regions of the display are arranged so that neighboring polarized elements have opposite polarities.
