摘要： A chiral nematic liquid crystal composition which contains a nematic liquid crystal mixture and a chiral agent, which exhibits a cholesteric phase at room temperature and which selectively reflects light of a specified wavelength, wherein the chiral agent has an anisotropy of dielectric constant within a range from 12 to 60. Such a chiral nematic liquid crystal composition may have a larger anisotropy of dielectric constant than the nematic liquid crystal mixture before being mixed with the chiral agent. Alternatively, in such a chiral nematic liquid crystal composition, the anisotropy of dielectric constant of the chiral agent may be larger than that of the nematic liquid crystal mixture. By filling such a chiral nematic liquid crystal composition between transparent substrates, a liquid crystal cell is fabricated, and by stacking such liquid crystal cells in three layers, a reflective type full-color liquid crystal display can be produced.
