And at least one of characteristics such as a high upper limit temperature, a low lower limit temperature, a small viscosity, a large optical anisotropy and a negative (-) large dielectric anisotropy, or an appropriate balance between at least two of these properties And a liquid crystal light modulating element comprising the composition. And may contain a specific compound having a negative dielectric anisotropy as a first component and a specific compound having a high upper limit temperature or a low lower limit temperature as a second component. |
