Definitions
- the present invention relates to a nematic liquid crystal composition having a negative dielectric anisotropy ( ⁇ ) useful as a liquid crystal display material, and a liquid crystal display device using the same.
- Liquid crystal display elements are used in clocks, calculators, various household electrical devices, measuring devices, automotive panels, word processors, electronic notebooks, printers, computers, televisions, and the like.
- Typical liquid crystal display methods include TN (twisted nematic), STN (super twisted nematic), DS (dynamic light scattering), GH (guest / host), and IPS (in-plane switching).
- Type OCB (optical compensation birefringence) type, ECB (voltage controlled birefringence) type, VA (vertical alignment) type, CSH (color super homeotropic) type, FLC (ferroelectric liquid crystal), etc.
- Examples of the driving method include static driving, multiplex driving, simple matrix method, active matrix (AM) method driven by TFT (thin film transistor), TFD (thin film diode), and the like.
- the IPS type, ECB type, VA type, CSH type, and the like have a feature that a liquid crystal material having a negative value of ⁇ is used.
- the VA type display method by AM driving is used for a display element that requires a high speed and a wide viewing angle, such as a television.
- a nematic liquid crystal composition used for a display method such as a VA type is required to have a low voltage drive, a high-speed response, and a wide operating temperature range. That is, ⁇ is negative, the absolute value is large, the viscosity is low, and a high nematic phase-isotropic liquid phase transition temperature (T ni ) is required. Further, from the setting of ⁇ n ⁇ d, which is the product of refractive index anisotropy ( ⁇ n) and cell gap (d), it is necessary to adjust ⁇ n of the liquid crystal material to an appropriate range according to the cell gap. In addition, when applying a liquid crystal display element to a television or the like, since high-speed response is important, a liquid crystal material having a low viscosity ( ⁇ ) is required.
- a liquid crystal composition using the following compounds (A) and (B) having a 2,3-difluorophenylene skeleton (see Patent Document 1) as a liquid crystal material having a negative ⁇ is disclosed.
- This liquid crystal composition uses the compounds (C) and (D) as compounds having ⁇ of almost 0, but this liquid crystal composition is sufficient for a liquid crystal composition that requires a high-speed response such as a liquid crystal television. Has not yet achieved a low viscosity.
- liquid crystal composition using a compound represented by the formula (G) has been disclosed (see Patent Document 4), and this liquid crystal composition also includes an alkenyl compound like the above compound (F). Therefore, there is a problem that display defects such as image sticking and display unevenness are likely to occur.
- Patent Documents 6 and 7 have already disclosed liquid crystal compositions using a compound having a fluorine-substituted terphenyl structure.
- Patent Document 8 discloses that the response speed of a homeotropic liquid crystal cell is improved by using a liquid crystal material having a large index (FoM) represented by (Equation 1), which is described in the specification. The improvement in the response speed of the liquid crystal composition used has not been sufficient.

Abstract
Description
また、式(A)及び式(G)にΔεがほぼゼロである式(III-F31)を組み合わせた液晶組成物(特許文献6参照)が開示されている。しかし、液晶表示素子の製造工程では液晶組成物を液晶セルに注入する際の極低圧で、蒸気圧が低い化合物は揮発してしまうため、その含有量を増やすことが出来ないと考えられていた。このため、該液晶組成物は式(III-F31)の含有量を限定してしまっており、大きなΔnを示すものの、粘度が著しく高いという問題があった。
また、特許文献8において、(式1)で示される指数(FoM)が大きい液晶材料を使用することでホメオトロピック液晶セルの応答速度を向上させることが開示されているが、明細書中に記載されている液晶組成物の応答速度の改善は十分とは言えるものではなかった。
