LCD device with multi-domain vertical alignment mode

Abstract

The invention relates to an LCD device with a multi-domain vertical alignment mode. The LCD device comprises a first substrate and a second substrate which are oppositely arranged, and a liquid crystal layer which is filled between the first substrate and the second substrate. A plurality of pixels are formed on the second substrate, a pixel electrode is formed in each pixel area, and a plurality of slits are formed on the pixel electrodes, a public electrode is formed on the surface of the first substrate, and projections or slits are formed on the public electrode, wherein, horizontal control electrodes are arranged under part of the slits on the pixel electrodes, the horizontal control electrodes are parallel to the slits, and width of the horizontal control electrodes is less than that of the slits. The LCD device with multi-domain vertical alignment mode helps realize multi-domain alignment, solve the problem of color shift, does not cause charge accumulation, and requires no complex drive.

Description

technical field [0001] The invention relates to a liquid crystal display device, in particular to a liquid crystal display device in which a horizontal electric field controls a multi-domain vertical alignment mode. Background technique [0002] Liquid crystals in liquid crystal display devices do not emit light by themselves. Liquid crystal display uses an electric field to control the twisting of liquid crystal molecules to control the light transmittance of the liquid crystal unit, so as to achieve the purpose of display. In a vertical alignment mode liquid crystal display device, a liquid crystal cell exhibiting negative dielectric anisotropy is used to constitute a liquid crystal cell. Referring to US Patent No. 6661488B1, as shown in FIG. 1 , an existing liquid crystal display device in a vertical alignment mode includes a first substrate 101 and a second substrate 104 oppositely arranged, and a liquid crystal filled between the first substrate 101 and the second subs...

Problems solved by technology

Due to the existence of capacitive coupling in the CC structure, the aperture ratio is reduced. In addition, due to the capacitive connection, the floating pixel electrode will cause charge accumulation, resulting in afterimages and reduced display quality.

The TT structure requires a large number of driver ICs and more complex driver ICs, resulting in an increase in cost
