ネマチック液晶組成物及びこれを用いた液晶表示素子
Abstract:
(EN)
[Problem] The present invention addresses the problem that a negative Δε value having a large absolute value, a small rotational viscosity (γ1), a large elastic modulus (K
33
), a low (solid phase)-(nematic phase) transition temperature (T
cn
), a high (nematic phase)-(isotropic liquid phase) transition temperature (T
ni
) and a large voltage holding ratio (VHR) are demanded. The present invention also addresses the problem of providing a rapid-response liquid crystal display element of a VA type, a PSVA type, a PSA type, a FFS type or the like, which is produced using the same, rarely undergoes or never undergoes display failures such as burning-in and display unevenness and has excellent display quality. [Solution] Provided are: a liquid crystal composition which contains a compound represented by formula (I-1) as a first component and a compound represented by formula (I-2) as a second component and has a negative dielectric anisotropy (Δε) value; and a liquid crystal display element produced using the liquid crystal composition.
(FR)
Le problème décrit par la présente invention est de fournir une valeur Δε négative ayant une valeur absolue importante, une faible viscosité de rotation (γ1), un grand coefficient d’élasticité (K
33
), une faible température de transition (phase solide)-(phase nématique) (T
cn
), une température de transition (phase nématique)-(phase liquide isotrope) élevée ((T
ni
) et un rapport de maintien de tension important (VHR). La présente invention traite également le problème de la fourniture d'un élément d'affichage à cristaux liquides à réponse rapide d'un type VA, d'un type PSVA, d'un type PSA, un type FFS ou similaire, qui est produit à l'aide de ladite composition, subissant rarement ou ne subissant pas de défaillances d'affichage telles que l’assombrissement et l'irrégularité d'affichage, et présentant une excellente qualité d'affichage. La solution de l'invention concerne : une composition de cristaux liquides qui contient un composé représenté par la formule (I-1) en tant que premier constituant et un composé représenté par la formule (I-2) en tant que second constituant et présentant une valeur d'anisotropie diélectrique négative (Δε) ; et un élément d'affichage à cristaux liquides produit à l'aide de la composition de cristaux liquides.

[課題]本発明が解決しようとする課題は、Δεが負で絶対値が大きく、低い回転粘性(γ
1
)、大きい弾性定数(K
33
)、低い固体相-ネマチック相転移温度(T
cn
)、高いネマチック相-等方性液体相転移温度(T
ni
)および高い電圧保持率(VHR)が求められていた。また、これを用いた焼き付きや表示ムラ等の表示不良がない又は抑制された、表示品位の優れた高速応答のVA型、PSVA型、PSA型、FFS型等の液晶表示素子を提供することにある。 [解決手段]第一成分として、式(I-1)で表される化合物を含有し、第二成分として、式(I-2)で表される化合物を含有し、誘電率異方性(Δε)が負の液晶組成物及びこれを用いた液晶表示素子を提供する。
