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 drive component areas, i.e. where switching elements and storage capacitors are located, are converted to associated dots by adding an electrode that can be electrically biased. The voltage polarity of the color dots and associated dots are arranged so that fringe fields in each color dot causes multiple liquid crystal domains in each color dot. Specifically, the color dots and associated dots of a pixel are arranged so that associated dots have opposite polarity as compared to neighboring color dots.
