Multiple-domain liquid crystal display

Abstract

A multi-domain liquid crystal display device comprises a first and a second pattern components and a plurality of first and second assistant electrodes; wherein the first and the second pattern components respectively have a first and a second polarities which are opposite to each other under the same picture controlled by a reversal rotary driving time sequence; the first and the second assistant electrodes are respectively connected with the first and the second pattern components; furthermore, the first and the second assistant electrodes are respectively wound around the second and the first pattern components.

Description

technical field [0001] The present invention relates to a multi-domain liquid crystal display, in particular to a multi-domain liquid crystal display with polarity inversion timing control to generate a fringe field effect. 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 or homeotropic alignment. When no voltage is applied, the liquid crystal molecules are aligned vertically. Arranged in the form of substrates, it can provide good contrast (contrast) performance. However, generally, in order to form a multi-domain splitting effect in a vertically aligned LCD, the matched structure may have some light leakage or insufficient multi-domain splitting configuration capability. [0003] FIG. 1A is a schematic cross-sectional view showing the design of a conventional multi-domain vertically aligned LCD (multi-domain vertically aligned...

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, etc. Otherwise, the force generated by the slit 206 to make the liquid crystal molecules 208 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
