Abstract:
Provided are a liquid crystal composition including at least one or more compounds represented by General Formula (i) and at least one or more compounds represented by General Formula (M-1), in which the dielectric constant anisotropy at 25° C. is larger than 0 and 5 or less; and a liquid crystal display element using this composition. The liquid crystal composition has a positive Δε, can have the electrical capacity of the liquid crystal layer (CLC) reduced to a low level, can be driven at a voltage that is practically sufficiently low, and satisfies at least any one of the requirements of maintaining a liquid crystal phase over a wider temperature range, low viscosity, satisfactory solubility at low temperature, high specific resistance or voltage retention rate, and stability to heat or light; and provide an excellent liquid crystal display element.
