Abstract:
1. A liquid crystal composition comprising: a first compound represented by formula (I) with a content of 5% to 25%, a second compound having a negative dielectric anisotropy (Δ∈) with an absolute value of greater than 3 and a content of 20% to 80% by mass, containing at least one compound represented by formula (II-1A): and one or more of compounds selected from a group of compounds represented by formulas (II-1B), and (II-2A): wherein R wherein Δ∈ at 25° C. is in a range of −2.0 to −6.0, a refractive index anisotropy (Δn) at 25° C. is in a range of 0.08 to 0.13, viscosity (η) at 20° C. is in a range of 10 to 30 mPa·s, and a nematic phase-isotropic liquid phase transition temperature (T
