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.

A pixel of a display comprising:
- a first color component having
- a first first-component color dot;
- a second first-component color dot adjacent to the first first-component color dot in a first dimension;
- and
- a first first-component polarity extension region coupled to the first first-component color dot and the second first-component color dot, wherein the first first-component polarity extension region extends beyond the first first-component color dot and the second first-component color dot along a second dimension;
- and
- a second color component having:
- a first second-component color dot;
- a second second-component color dot adjacent to the first second-component color dot in the first dimension;
- a first second-component polarity extension region coupled to the first second-component color dot and the second second-component color dot, wherein the first second-component polarity extension region extends beyond the first second-component color dot and the second second-component color dot along the second dimension.
A display comprising:
