Technical field
The present invention relates to a kind of liquid-crystal composition and its liquid crystal display device, more particularly to it is a kind of have appropriate optics respectively to
Different in nature, appropriate dielectric anisotropy, higher clearing point, relatively low rotary viscosity liquid-crystal composition and include the liquid-crystal composition
Liquid crystal display device.
Background technology
For liquid crystal display cells, PC (phase change, phase transformation), TN are divided into according to the display pattern of liquid crystal
(twist nematic, twisted-nematic), STN (super twisted nematic, super twisted nematic), ECB
(electrically controlled birefringence, electrically conerolled birefringence), OCB (optically compensated
It is bend, optical compensation curved), IPS (in-plane switching, coplanar transformation), VA (vertical alignment, hang down
Straight orientation) etc. type.PM (passive matrix, passive-matrix) types and AM (active are divided into according to the type of drive of element
Matrix, active-matrix) type.PM points are the static state type such as (static) and multichannel (multiplex).AM points are TFT (thin
