Abstract:
A liquid crystal is provided, which can be used in a liquid crystal display (LCD) to provide an LCD exhibiting a good transmittance. The liquid crystal according to the invention has the following properties: (i) a dielectric anisotropy (Δ∈) ranging from about −2.5 to about −5; (ii) a splay elastic constant (K11) ranging from about 1.1×10−11 N to about 1.6×10−11 N; (iii) a bend elastic constant (K33) ranging from about 1.1×10−11 N to about 1.6×10−11 N; and (iv) Δ∈, K11 (N) and K33 (N) conforming to the following equation: K 11 + K 33 10 × Δ ɛ
