    摘要: A liquid crystal display which carries out matrix driving of a chiral nematic liquid crystal composition, which is capable of displaying an image theron continuously after an electric field applied thereto is turned off, by applying an electric field to the liquid crystal composition through a plurality of scan electrodes and a plurality of data electrodes which face and cross each other with the liquid crystal composition in-between. The nematic liquid crystal which is the main element of the liquid crystal composition mainly contains a liquid crystalline ester compound, a liquid crystalline stilbene compound, a liquid crystalline terphenyl compound or a liquid crystalline tolane compound. A driving section of the liquid crystal display drives the liquid crystal composition by a driving method which comprises a reset step of applying a reset pulse to cause the liquid crystal composition to come to a homeotropic state, a selection step of applying a selection pulse to select a final state of the liquid crystal composition and an evolution step of applying an evolution pulse to cause the liquid crystal composition to evolve to the selected final state and in which the selection of the final state of the liquid crystal composition is carried out by modulating the selection pulse.

    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.
