摘要: A phase transition-type liquid crystal composition including a mixture of ester-type liquid crystal compound and chiral nematic liquid crystal compound having added thereto at least one of ethane-type liquid crystal compound and bicyclohexane-type liquid crystal compound. The liquid crystal composition exhibits an extended width (.DELTA.V) of voltage hysteresis and therefore a stabilized homeotropic (H') state, when its voltage hysteresis curve is plotted. The liquid crystal display devices or elements using this composition have a fast response characteristic and enable a large scale or area display and an input operation using keyboards.

摘要: A storage type liquid crystal composition in which a nematic-cholesteric mesophase transition is utilized and the anisotropy of the dielectric constant is positive and an X-Y dot-matrix-type storage-type liquid-crystal display element comprising the composition. The present liquid crystal composition has low driving voltage and long memory effect. This composition comprises a cyclohexane-type liquid crystal, an azoxy-type liquid crystal, and a compensated cholesteric liquid crystal and/or cholesteryl oleate.

摘要: A cholesteric-nematic phase transition type liquid crystal with positive dielectric anisotropy is used in a projection type liquid crystal display device. This allows a bright and high information contents display with a compact, light, and low cost device and allows machinery input and thus simultaneous display at remote places, such as remote conference rooms or remote notice boards, in bright locations.
