Multi- domain LCD device

Abstract

A multi-domain liquid crystal display comprises two transparent substrates, a liquid crystal layer disposed therebetween, a common electrode, a first metal layer, a first dielectric layer, a second metal layer, a second dielectric layer, a plurality of pixel electrodes, and a plurality of auxiliary electrodes. The first dielectric layer is formed on the second transparent substrate and covers thefirst metal layer, the second metal layer is formed on the first dielectric layer, and the second dielectric layer is formed on the first dielectric layer and covers the second metal layer. The plurality of pixel electrodes are formed on the second dielectric layer, each being provided with at least one opening extending inwardly from the fringe so as to be partitioned into a plurality of blocks.The plurality of auxiliary electrodes are formed on the second dielectric layer, each being adjacent to at least one side of one pixel electrode block while being at least distributed inside the opening of the pixel electrode to form a fringe field, and at least one opening is formed at a position where the second metal layer laminating the auxiliary electrodes.

Description

technical field [0001] The invention relates to a liquid crystal display with multi-domain alignment. Background technique [0002] The existing liquid crystal alignment method using negative type liquid crystal material with negative dielectric anisotropy to form vertical alignment (vertical alignment), because the liquid crystal molecules are arranged vertically to the substrate when no voltage is applied, it can provide 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] Figure 11A It is a schematic cross-sectional view showing the design of a conventional multi-domain vertically aligned LCD (MVA LCD). Such as Figure 11A As shown, bumps 106 are respectively formed on the upper and lower substrates 102, 104, and a vertical alignment film 108 covering the bumps 106 is formed on the uppe...

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
