Description
Technical field
The present invention relates to it is a kind of meet big refractive index or big dielectric while, take into account the liquid crystal group of fast-response and high reliability
Close object, and the liquid crystal display device comprising the liquid-crystal composition.
Background technique
The various fields used for liquid crystal display device shown in information can be used for straight watching display and be also used for projection type to show
Device.
According to the type of display pattern be divided into PC (phase change, phase transformation), TN (twist nematic, distort to
Column), STN (super twisted nematic, super twisted nematic), ECB (electrically controlled
Birefringence, electrically conerolled birefringence), OCB (optically compensated bend, optical compensation curved), IPS
The types such as (in-plane switching, coplanar transformation), VA (vertical alignment, vertical orientation).
Work uses positive dielectric anisotropic liquid crystal in the element of TN, STN mode, and works in the element use of VA mode
Positive dielectric anisotropic liquid crystal had both can be used in negative dielectric anisotropic liquid crystal, IPS/FFS mode, it is possible to use negative dielectric items are different
Property liquid crystal.Wherein, IPS display pattern has good viewing angle characteristic and improved response time, by more and more for more
Media application (such as mobile phone, tablet computer), so it is used for TV and desktop monitor.
Liquid crystal display device containing optical anisotropy liquid crystal material appropriate is capable of increasing contrast.Different liquid crystal
Requirement of the display pattern to optics anisotropic be it is different, optics anisotropic, which becomes smaller, can get wider visual angle.
Containing the big liquid crystal material of dielectric anisotropic, the threshold voltage of liquid crystal can be reduced, further decreases consumption electric work
Rate, but the bigger dielectric the easier causes ion releasing by photo-thermal electrodisintegration, so as to cause resistivity reduction.
Liquid crystal display device containing the small liquid crystal material of viscosity can shorten the response time.When the sound of liquid crystal display device
Between seasonable in short-term, it is applicable to animation and shows.
Liquid crystal display device containing the big liquid crystal material of resistivity is capable of increasing voltage retention, and can increase comparison
Degree.Thus, even if liquid crystal material needs still to have big electricity after long-time use with big resistivity value, further in the early stage
Values of resistivity.Under same voltage conditions, current value is smaller, and resistivity is bigger.
But the prior art generally existing the problem of cannot be considered in terms of fast-response and high reliability while meeting big refraction.
Therefore, in order to obtain stable liquid crystal display state, reach above-mentioned requirements, provided by the optimization of liquid crystal material
Under the premise of meeting existing big refraction or big dielectric, at the same meet fast-response, high reliability performance requirement liquid crystal material,
It is the striving direction of those skilled in the art.
From the preparation angle of liquid crystal material, the properties of liquid crystal material check and balance influence, a certain performance
The promotion of index may make other performances change.Therefore, the preparation all suitable liquid crystal material of various aspects of performance often needs
Want creative work.
The object of the present invention is to provide one kind while meeting big refractive index, takes into account the liquid of fast-response and high reliability
