Liquid crystal composition, liquid crystal display element and use of liquid crystal composition in liquid crystal display element

Abstract

To provide a liquid crystal composition that satisfies at least one property such as high upper temperature limit, low lower temperature limit, low viscosity, appropriate optical anisotropy, large dielectric anisotropy, large dielectric constant in the short-axis direction, a large ratio of dielectric constant in the short-axis direction to dielectric anisotropy, high specific resistance, high stability against light and heat, and large elastic constant, or that possesses a suitable balance for at least two of these properties, and to provide an AM device including this composition. It is a liquid crystal composition that may contain, as component A, a specific compound having a large optical anisotropy; as component B, a specific compound having a large dielectric anisotropy; as component C, a specific compound having low viscosity or a high upper temperature limit; or as component D, a specific compound having a large dielectric constant in the short-axis direction.
