Background technology
Liquid crystal display panel typically by a color membrane substrates (Color Filter Substrate, CF
Substrate), thin-film transistor array base-plate (Thin Film Transistor Array Substrate, TFT
Array Substrate) and a liquid crystal layer being configured between two substrates (Liquid Crystal Layer) constituted, its work
It is to control the rotation of the liquid crystal molecule of liquid crystal layer by applying driving voltage on two panels glass substrate as principle, by backlight mould
The light of group reflects generation picture.According to the aligned difference of liquid crystal, the liquid crystal display panel on current mainstream market
Following several types can be divided into：Vertical orientation (Vertical Alignment, VA) type, twisted-nematic (Twisted
Nematic, TN) or super twisted nematic (Super Twisted Nematic, STN) type, plane conversion (In-Plane
Switching, IPS) type and fringe field switching (Fringe Field Switching, FFS) type.
For VA patterns, liquid crystal display device is mainly by upper and lower two substrates, and is located between two substrates
Negative liquid crystal molecular composition.There is transparency conducting layer (tin indium oxide, ITO) in the inner side of upper and lower two substrates, such that it is able to be formed
Vertical electric field：The embedded negative liquid crystal between two-layer transparency conducting layer, in the case where no vertical electric field is acted on, liquid crystal point
Perpendicular to substrate surface orientation, when there is vertical electric field to act on, liquid crystal molecule the orientation of specific direction to son can occur, final vertical
In direction of an electric field arrangement.
VA patterns have high-contrast, the picture display advantage of high-penetration rate, but because VA patterns are using vertical rotation
Liquid crystal, the diversity ratio of liquid crystal molecule birefringence is larger, cause that its visual angle is poor, the colour cast problem under big visual angle than more serious,
Generally use multidomain VA technologies, will a sub-pixel be divided into multiple regions, and applying the liquid crystal molecule in each region
