Abstract
A liquid crystal composition, which is a material used for an element for electromagnetic wave signal control in a frequency range of 1 GHz to 10 THz, satisfies at least one of characteristics such as a wide temperature range of a nematic phase and a large refractive index anisotropy and a small dielectric loss tangent (tan δ) in the frequency region used for control, and has an excellent balance of characteristics, and an element containing the composition. A liquid crystal composition including: at least one compound selected from the group consisting of compounds represented by Formula (1). For example, R1 is C1-12 alkyl; Z11 is a single bond; L11, L12, L13 and L18 are hydrogen; L17 is methyl; Y11 and Y22 are hydrogen; and a and c are respectively 0 or 1, b is 1, and a sum of a, b, and c is 2.
