Description
Technical field
It is more particularly to a kind of that there is suitable optical anisotropy, suitable Jie the present invention relates to a kind of liquid-crystal composition
Electrical anisotropy, higher clearing point, faster response speed, the liquid of preferable anti-UV stability and preferable high-temperature stability
Crystal composite, and the liquid crystal display device comprising the liquid-crystal composition.
Background technology
Liquid crystal material is the not only mobility with liquid but also anisotropic organic with crystal at a certain temperature
The mixture of bar-shaped micromolecular compound.Liquid crystal display cells be optical anisotropy in itself that have using liquid crystal material and
Dielectric anisotropy has been widely used at present come what is be operated.Utilize the different characteristic of liquid crystal material and work
Mode, can design device to a variety of mode of operations, and what wherein conventional display was generally used has (the distortion of TN patterns
Nematic-mode, liquid crystal compound has the nematic structure of about 90 degree of torsion resistance), STN mode (supertwisted nematic mode), SBE
Pattern (SBE), ecb mode (electrically conerolled birefringence), VA patterns (vertical arrangement), IPS (being changed in face) etc., also have
Many improved modes made according to any of the above pattern.
