摘要: A liquid crystal composition satisfying at least one characteristic such as high maximum temperature, low minimum temperature, small viscosity, suitable optical anisotropy, large negative dielectric anisotropy, large specific resistance, high stability to UV light, to heat or the like, or having a suitable balance regarding at least two of the characteristics, and an AM device having characteristics such as a short response time, a large voltage holding ratio, a low threshold voltage, a large contrast ratio and a long service life are shown. The liquid crystal composition contains a specific compound having at least three polymerizable groups, and the liquid crystal display device includes the composition. The composition may contain a specific compound having large negative dielectric anisotropy as a first component, and a specific compound having a high maximum temperature or small viscosity as a second component.
