LIQUID CRYSTAL COMPOSITION AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

To show a liquid crystal composition satisfying at least one of characteristics such as a high maximum temperature of a nematic phase, a low minimum temperature thereof, small viscosity, suitable optical anisotropy, large positive dielectric anisotropy or having a suitable balance regarding at least two of the characteristics, and an AM device including the liquid crystal composition. The liquid crystal composition contains a specific compound having high maximum temperature and low minimum temperature as a first component, and the liquid crystal composition may contain a specific compound having large positive dielectric anisotropy as a second component, a specific compound having high maximum temperature or small viscosity as a third component, a specific compound having large positive dielectric anisotropy as a fourth component, or a specific compound having negative dielectric anisotropy as a fifth component.
