Beschreibung
Zusammenfassung:	To provide a liquid crystal composition satisfying at least one of demands for characteristics such as a high maximum temperature, low minimum temperature, small viscosity, large optical anisotropy, large dielectric anisotropy and large elastic modulus or having an appropriate balance in at least two of the characteristics, and an AM element comprising the composition.SOLUTION: The liquid crystal composition contains a specific compound having a polymerizable group as a first additive, contains a specific compound having a negative dielectric anisotropy as a first component, and may contain a specific compound having a high maximum temperature or a small viscosity as a second component or a specific compound having a polymerizable group as a second additive.SELECTED DRAWING: None 【課題】高い上限温度、低い下限温度、小さな粘度、大きな光学異方性、大きな誘電率異方性、大きな弾性定数などの特性において、少なくとも１つの特性を充足する、または少なくとも２つの特性に関して適切なバランスを有する液晶組成物、およびこの組成物を含むＡＭ素子を提供する。【解決手段】第一添加物として重合性基を有する特定の化合物を含有し、第一成分として負の誘電率異方性を有する特定の化合物を含有し、第二成分として高い上限温度または小さな粘度を有する特定の化合物、または第二添加物として重合性基を有する特定の化合物を含有してもよい液晶組成物である。【選択図】なし
