PROBLEM TO BE SOLVED: To optimize Δn of a liquid crystal composition by mixing with a liquid crystal composition, to reduce viscosity and threshold voltage Vth, and to have good mutual solubility with various liquid crystal compounds. To provide simple compounds. SOLUTION: An ester derivative represented by the following formula. Embedded image (Provided that V, W, X, Y and Z each represent a hydrogen atom or F or Cl, and at least one of them is F or Cl, and when V or W is Cl, Alternatively, at least one of W, Y, and Z is F or Cl.) |
