Abstract
A liquid crystal composition for field effect display devices, comprising a nematic liquid crystal composition having a substantially positive dielectric anisotropy and at least one of o-terphenyl and m-terphenyl. This composition sufficiently functions at 2 V, because the threshold voltage of the liquid crystal composition can be made about 1.5 V.
