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 polarities of the color dots are arranged so that fringe fields in each color dots causes multiple liquid crystal domains in each color dot. Specifically, the color dots of a pixel are arranged so that each color dot of a first polarity has four neighboring pixels of a second polarity. Thus, a checkerboard pattern of polarities is formed. Furthermore, the checkerboard pattern is extended across multiple pixels in the MVA LCD. In addition, many display unit include multiple pixel designs to improve color distribution or electrical distribution.
