【発明の詳細な説明】 [産業上の利用分野] 本発明は表示素子用として有用な新規なピリジン系液晶
化合物に関する。The present invention relates to a novel pyridine-based liquid crystal compound useful as a display device.
[従来の技術] 現在、液晶表示素子としてはTN(ねじれネマチック)型

究が進められている強誘電性液晶を用いる新しい表示方
式においては、著しい応答速度の改善の可能性がある

イラルスメクチックF、G、H、I等の相が強誘電性を
示すことが知られている。[Prior Art] Currently, a TN (twisted nematic) type display system is most widely used as a liquid crystal display element. This TN liquid crystal display has many advantages such as low driving voltage and low power consumption. However, it is inferior in terms of response speed to light emitting devices (cathode tube, electroluminescence, plasma display, etc.). Twist angle
Although a new TN type display device with 180-270 ° has been developed, the response speed is still poor. Although various efforts have been made to improve the TN type display element having a high response speed, it has not been realized yet. However, in a new display method using a ferroelectric liquid crystal, which has been actively researched recently, there is a possibility that the response speed is significantly improved (NAClark et al; Applied Phys.lett., 36,899 (198
0)). This method utilizes a chiral smectic phase such as a chiral smectic C phase exhibiting ferroelectricity. It is known that not only the chiral Sc phase but also the chiral smectic F, G, H, I, etc. exhibit ferroelectricity.
実際に利用される強誘電性液晶表示素子に使用される強
誘電性液晶材料には多くの特性が要求されるが、それら
を満たすには現在のところ、一つの化合物では応じられ
ず、いくつかの液晶化合物または非液晶化合物を混合し
て得られる強誘電性液晶組成物を使用する必要がある。Many properties are required for the ferroelectric liquid crystal material used for the ferroelectric liquid crystal display element actually used, but at present, one compound cannot meet the requirements. It is necessary to use the ferroelectric liquid crystal composition obtained by mixing the liquid crystal compound or the non-liquid crystal compound.
また、強誘電性液晶化合物のみからなる強誘電性液晶組

液晶相は呈しない一種あるいは複数の化合物を混合して
全体を強誘電性液晶組成物とする報告も見受けられる
(Mol.Cryst.Liq.Cryst.,89,327(1982))。Further, not only a ferroelectric liquid crystal composition consisting only of a ferroelectric liquid crystal compound but also a compound exhibiting a non-chiral smectic C, F, G, H, I phase and the like in JP-A-60-36003, It has been reported that the composition can be used as a basic substance and one or a plurality of compounds exhibiting a ferroelectric liquid crystal phase can be mixed with the composition to form a ferroelectric liquid crystal composition as a whole. Furthermore, a compound and a composition exhibiting a phase such as smectic C are used as a basic substance, and one or a plurality of compounds which are optically active but do not exhibit a ferroelectric liquid crystal phase are mixed to make a whole ferroelectric liquid crystal composition. Can also be seen (Mol.Cryst.Liq.Cryst., 89,327 (1982)).
これらのことを総合すると強誘電性液晶相を呈するか否
にかかわらず光学活性である化合物の一種または複数を
基本物質と混合して強誘電性液晶組成物を構成できるこ
とがわかる。Taking all of these into consideration, it can be seen that a ferroelectric liquid crystal composition can be formed by mixing one or more optically active compounds with a basic substance regardless of whether or not they exhibit a ferroelectric liquid crystal phase.
これらの基本物質としては、スメクチックC等の非カイ

ニル)ピリミジンなどの液晶化合物が挙げられる。As these basic substances, various compounds exhibiting a non-chiral smectic liquid crystal phase such as smectic C are used, but practically, a liquid crystal compound or a mixture exhibiting a smectic C phase in a wide temperature range including room temperature is desirable. As a component of these smectic C liquid crystal mixtures,
Liquid crystal compounds such as phenylbenzoate-based, biphenyl-based, phenylpyridine-based and 5-alkyl-2- (4-alkoxyphenyl) pyrimidines can be mentioned.

である。[Problems to be Solved by the Invention] However, as to whether or not the chiral smectic C liquid crystal material obtained by adding an optically active compound to them exhibits excellent performance in liquid crystal display utilizing ferroelectricity, , The final evaluation has not been obtained yet. This is because the liquid crystal display utilizing ferroelectricity has not been technically completed. Therefore, at present, it is necessary to test various materials for new smectic C liquid crystal compositions.
