されているネマチック液晶は電気光学応答時間が約５０

利用には制限がある。また表示容量の点でも限界に達し
つつある。(Prior Art) Liquid crystal elements are widely used in electro-optical devices such as wristwatches, calculators, personal computer displays, and pocket color televisions. However, the electro-optical response time of currently used nematic liquid crystals is approximately 50
Since it is slow at m sec, its use in fields where high-speed response is required is limited. In addition, we are reaching the limit in terms of display capacity.
一方、強誘電性液晶はμｓｅｃ単位の高速応答性を示す
ため、その実用化により液晶素子の用途の飛躍的拡大を
もたらすことが期待されている。On the other hand, since ferroelectric liquid crystals exhibit high-speed response on the μsec scale, their practical use is expected to dramatically expand the applications of liquid crystal elements.
強誘電性液晶材料は１９７５年、Ｒ，Ｂ、メイヤー等に
よって合成されたいわゆるＤＯＢＡＭＢＣＣＨ。The ferroelectric liquid crystal material is so-called DOBAMBCCH, which was synthesized by R. B. Mayer et al. in 1975.
から端を発しくＪ、ｄｅ Ｐｈｙｓｉｑｕｅ、３６．１

ＳＣ＊相の温度範囲が７３〜９３℃と高温にあり、単独
での実用的使用は困難である。Originating from J, de Physique, 36.1
~69 (1975)) to the present. Ferroelectric liquid crystals are characterized by having a chiral smectic C phase (hereinafter abbreviated as SC* phase), but the temperature range of the SC* phase in 10BA14BC is as high as 73 to 93°C, making it difficult to use alone for practical use. Difficult to use.
また分子内にシック塩基と炭素−炭素２重結合を有する
点から化学的安定性にも問題をもっている。It also has problems with chemical stability because it has a thick base and a carbon-carbon double bond in its molecule.
実用上の観点から強誘電性液晶には室温を含む広い温度
範囲でのＳＣ零相の出現と、化学的安定性が一義的に求
められる。ａ近この点に注意を払われた様々な強誘電性
液晶、すなわちエステル系、ビフェニル系、ピリミジン
系の合成が精力的に進められてきている。From a practical standpoint, ferroelectric liquid crystals are primarily required to exhibit SC zero phase in a wide temperature range including room temperature and to have chemical stability. Recently, attention has been paid to the synthesis of various ferroelectric liquid crystals, ie, ester, biphenyl, and pyrimidine liquid crystals.
しかし、上記の系の材料は化学的安定性には満足するも

が現在用いられている。またブレンドはＳＣ＊相の温度
範囲の拡大以外にも各種の諸物性、例えば電気光学的な
応答性や配向性に影響を及ぼずピッチ等の改善に重要な
手法である。However, although the above-mentioned materials have satisfactory chemical stability, it is difficult to obtain a ferroelectric liquid crystal of a single composition that has a wide temperature range for practical use. Therefore, as in the case of nematic liquid crystals that have already been put into practical use, a method is currently being used for ferroelectric liquid crystals to expand the temperature range of the Sc* phase by blending several types of materials. In addition to expanding the temperature range of the SC* phase, blending does not affect various physical properties, such as electro-optic response and orientation, and is an important method for improving pitch and the like.
しかし現在ブレンドに用いる際に必要な強誘電性液晶の
種類は非常に少なく不充分な状態にあるといえる。However, at present, the number of types of ferroelectric liquid crystals required for use in blending is very small and insufficient.
