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.

A pixel of a display comprising:
- a first color component having
- a first first-component color dot;
- and
- a second first-component color dot aligned with the first first-component color dot in a first dimension;
- a first fringe field amplifying region having
- a first first-fringe-field-amplifying-region vertical amplifying portion extending vertically along a first side of the first first-component color dot, and along a first side of the second first-component color dot;
- and
- a first first-fringe-field-amplifying-region horizontal amplifying portion extending horizontally along a second side of the first first-component color dot and along a second side of the second first-component color dot;
- and
- a first switching element located within the first first-fringe-field-amplifying-region horizontal amplifying portion, wherein the first switching element is coupled to the first color component.
A pixel of a display comprising:
- a first color component having
- a first first-component color dot;
- and
- a second first-component color dot aligned with the first first-component color dot in a first dimension;
- and
- a third first-component color dot aligned with the second first-component color dot in the first dimension;
- and
- a first fringe field amplifying region having
- a first first-fringe-field-amplifying-region vertical amplifying portion extending vertically along a first side of the first first-component color dot;
- and
- a first first-fringe-field-amplifying-region horizontal amplifying portion extending horizontally along a second side of the first first-component color dot;
- a second first-fringe-field-amplifying-region horizontal amplifying portion extending between the second first-component color dot and the third first-component color dot;
- wherein the first first-fringe-field-amplifying-region horizontal amplifying portion extends along a first side of the second first-component color dot and the first first-fringe-field-amplifying-region vertical amplifying portion extends along a second side of the second first-component color dot;
- a first switching element located within the second first-fringe-field-amplifying-region horizontal amplifying portion, wherein the first switching element is coupled to the first color component.
A pixel of a display comprising:
