Multi-domain LCD

Abstract

The invention provides a multizone liquid crystal display which comprises a plurality of display pixel electrodes, a plurality of nominal pixel electrodes and a plurality of auxiliary electrodes. A display pixel electrode array is formed by regularly arranging the display pixel electrodes and is formed into the display area of the multizone liquid crystal display. The nominal pixel electrodes are positioned outside the display area and at least are arranged on a row of or a line of lateral side on the outermost periphery of the display pixel electrode array. Each auxiliary electrode is connected with a display pixel electrode controlled by a primary signal line or a rear signal line and is adjacent to the lateral side of each display pixel electrode or each nominal pixel electrode to as to form an edge electric field together with the adjacent display pixel electrodes or the nominal pixel electrodes and ensure that all the display pixel electrodes have similar coupling capacitance value.

Description

technical field [0001] The invention relates to a liquid crystal display, in particular to a multi-domain alignment liquid crystal display with good brightness uniformity of pixels. Background technique [0002] It is known that a negative type liquid crystal material with a negative dielectric anisotropy is used to form a liquid crystal alignment method of vertical alignment. When no voltage is applied, the liquid crystal molecules are arranged vertically to the substrate, so it can provide a good Contrast performance. However, in order to form a multi-domain splitting effect in a vertically aligned LCD, the matching structure may have some light leakage or insufficient multi-domain splitting configuration capability. [0003] FIG. 12 is a schematic cross-sectional view showing the design of a conventional multi-domain vertically aligned LCD (multi-domain vertically aligned LCD; MVA LCD). As shown in FIG. 12 , bumps 106 are formed on the upper and lower substrates 102 and...

Problems solved by technology

However, the way to form the slit 206 at the electrode 204 must carefully consider the width of the slit 206 itself and the distance between the two slits 206, or the force generated by the slit 206 to cause the liquid crystal molecules 208 to fall is easily insufficient.

Furthermore, the design of the slit 206 causes the energy of the liquid crystal molecules 208 to rotate in either direction to be equal, so that the alignment distribution of the liquid crystal molecules 208 in space produces discontinuous disclination.

The misalignment defect region 210 is easily formed above the slit 206 and between the two slits 206, thereby reducing the overall light transmittance
