Problems solved by technology

However, indium tin oxide trenches are also very expensive to fabricate
Furthermore, whether it is a protrusion or an ITO groove, it will block the passage of light beams and reduce the brightness of the multi-domain vertical alignment liquid crystal display.

Embodiment Construction

[0097] As mentioned above, since the known technology must make physical features such as protrusions or ITO trenches to achieve multi-domain effects in each pixel, the production cost of traditional multi-domain vertical alignment liquid crystal displays very expensive. However, the multi-domain vertical alignment liquid crystal display according to the concept of the present invention utilizes fringe electric fields to generate multi-domain effects, and does not require physical features such as protrusions or ITO trenches on the substrate. Furthermore, when these physical features are not needed, the difficulty of accurately aligning and assembling the physical features on the upper and lower substrates in the prior art can also be eliminated. Therefore, compared with the traditional multi-domain vertical alignment liquid crystal display, the multi-domain vertical alignment liquid crystal display according to the present invention has higher yield and lower manufacturing co...

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.

Description

technical field [0001] The present invention relates to a liquid crystal display (LCD), and more particularly to a multi-domain vertically aligned liquid crystal display with large pixels, and the liquid crystal display is fabricated on a smooth substrate. Background technique [0002] Liquid crystal displays were originally used for monochrome displays such as computers and electronic watches, but now they have become the mainstream of display technology, and in the computer monitor or television display industry, liquid crystal displays have replaced cathode ray tubes (cathode ray tubes, CRT). In addition, many disadvantages of LCDs have been overcome to improve the quality of LCDs. For example, compared to passive array displays, active array displays can reduce ghosting and improve resolution, color scale, viewing angle, contrast, and response time, and have widely replaced Passive Array Display. [0003] However, the main disadvantages of conventional twisted nematic...
