Ester derivative having a positive dielectric anisotropy |
| abstract |
A novel ester derivative affording a positive large dielectric anisotropy value (Δε) of liquid crystal compositions and also reducing the optical anisotropy value (Δn) thereof when the derivative is contained therein, and a liquid crystal composition containing the ester derivative are provided, which ester derivative is expressed by the formula ##STR1## wherein R represents an alkyl group or an alkoxy group each of 1 to 10 carbon atoms and X represents F or Cl. |
