Beschreibung
Zusammenfassung:	The present invention relates to a liquid crystal composition which contains (A) a liquid crystal compound, (B) a polymerizable liquid crystal compound having a cyanophenyl group and (C) a polymerizable compound having two or more polymerizable groups, and which is configured such that the nematic phase-isotropic phase transition temperature (TNI) of the liquid crystal compound (A) is within the range of from 20°C to 120°C. La présente invention concerne une composition de cristaux liquides qui contient (A) un composé de cristaux liquides, (B) un composé de cristaux liquides polymérisable ayant un groupe cyanophényle, et (C) un composé polymérisable ayant deux groupes polymérisables ou plus, et qui est configurée de telle sorte que la température de transition phase nématique-phase isotrope (TNI) du composé de cristaux liquides (A) se situe dans la plage allant de 20°C à 120°C. 本発明は、液晶化合物（Ａ）、シアノフェニル基を有する重合性液晶化合物（Ｂ）、および、２個以上の重合性基を有する重合性化合物（Ｃ）を含み、　前記液晶化合物（Ａ）のネマチック相から等方相への相転移温度（ＴＮＩ）が２０～１２０℃の範囲にある、液晶組成物に関する。
