A short review of liquid crystal compounds with a low birefringence and ordinary refractive index is presented. Special attention is given to alkylcyclohexylalkyl carbonates, which belongs to a family of LCs having high clearing point temperatures, low viscosity and n_o as low as 1.442. Examples of multicomponent mixtures with positive and negative dielectric anisotropy are described.
