In vertical orientated (VA) escope, use Δ ε to be negative liquid-crystal composition, in the horizontal alignment escopes such as TN type, STN type or IPS (plane conversion) type, use Δ ε to be positive liquid-crystal composition.In addition, also report and to make when not applying voltage Δ ε be that positive liquid-crystal composition is vertical orientated and by applying the type of drive that transverse electric field carries out showing, thus Δ ε is that the necessity of positive liquid-crystal composition improves further.On the other hand, in all type of drive, require low voltage drive, high-speed response, wide operating temperature range.That is, require that Δ ε is just and absolute value is large, viscosity (η) is little, nematic phase-isotropic liquid phase transition temperature (Tni) is high.In addition, in order to the product of Δ n and cell gap (セ Le ギ ャ ッ プ) (d) and Δ n × d are set as prescribed value, need to be adjusted to suitable scope by mutually suitable to the Δ n of liquid-crystal composition and cell gap.In addition, paying attention to high-speed response when liquid crystal display device being applied to televisor etc., therefore requiring rotational viscosity (γ 1) little liquid-crystal composition
As the formation of liquid-crystal composition pursuing high-speed response, such as, disclose and combinationally use Δ ε to be the compound that represents of positive liquid crystalline cpd and following formula (A-1) or following formula (A-2) and Δ ε be liquid-crystal composition that compound that neutral liquid crystalline cpd and following formula (B) represent obtains.The feature of these liquid-crystal compositions is Δ ε is that positive liquid crystalline cpd has-CF 2o-structure and Δ ε are that neutral liquid crystalline cpd has alkenyl.These features well-known in the field of this liquid-crystal composition (with reference to patent documentation 1 ~ 4).
On the other hand, the purposes of liquid crystal display device expands, and wide variation have also appearred in its using method, manufacture method.In order to tackle these changes, require the characteristic optimization made except in the past known basic physical properties value.That is, use the liquid crystal display device of liquid-crystal composition to reach and widely use VA type, IPS type etc., its size is that the display element of the ultra-large type size of more than 50 types has also reached practical, and is used.Along with the maximization of substrate size, the method for implanting to substrate injection liquid crystal composite also there occurs change, and the main flow of method for implanting changes instillation (ODF:One Drop Fill) method into from vacuum impregnation in the past.But, to drop impression during substrate dropping liquid crystal composite, the problem causing display quality to reduce is revealed.In addition, in the liquid crystal display device manufacturing process utilizing ODF method, the liquid crystal dripping optimal dose according to the size of liquid crystal display device is needed.If dripping quantity with just when deviation large, then the specific refractory power of the liquid crystal display device designed in advance, the balance of driving electric field are destroyed, and it is bad to produce the displays such as spot, contrast gradient be bad.Particularly, the small-scale liquid crystal display element being used for smart mobile phone popular recently due to the suitableeest liquid crystal drop dosage few, so itself be difficult to by with just when deviation control in constant range.Therefore, in order to keep the fabrication yield of liquid crystal display device higher, for liquid-crystal composition, such as, need by the impact that intense pressure changes, impact causes in the Dropping feeder produced during dropping liquid crystal little, can continue long-term and stably to drip.
Like this, for the liquid-crystal composition used in the driven with active matrix liquid crystal display device driven by TFT element etc., while maintenance high speed response property etc. is as the characteristic required by liquid crystal display device, performance, the high resistivity value, the high voltage holding ratio that also require to consider to come into one's own, the characteristic of the stability of the external stimulus such as light, heat and the manufacture method of liquid crystal display device to be developed in the past always.
