Abstract: front page image
(EN)Disclosed is a liquid crystalline medium which has a wide liquid crystal phase temperature range, a high refractive index anisotropy and high dielectric anisotropy, and has an optically isotropic liquid crystal phase. The liquid crystalline medium comprises a liquid crystalline compound having a pyridine ring and a linking group –CF2O- and a chiral agent, and can exhibit an optically isotropic liquid crystal phase.
(FR)La présente invention concerne un milieu cristal liquide ayant une large plage de températures de phase cristal liquide, une anisotropie à indice de réfraction élevé et une anisotropie diélectrique élevé, et présentant une phase cristal liquide optiquement isotrope. Le milieu cristal liquide comporte un composé cristaux liquides ayant un noyau pyridine et un groupe de liaison –CF2O- et un agent chiral, et peut présenter une phase cristal liquide optiquement isotrope.
(JA)広い液晶相温度範囲、大きな屈折率異方性、大きな誘電率異方性を有し、光学的に等方性の液晶相を有する液晶媒体を提供する。 ピリミジン環および連結基-CFO-を有する液晶化合物およびキラル剤を含有し、光学的に等方性の液晶相を発現することを特徴とする液晶媒体。
