    摘要: Cholesteric liquid crystal compositions and a recording medium which includes cholesteric liquid crystal composition are disclosed. The cholesteric liquid crystal composition has a characteristic, in a cholesteric phase, of reflecting visible light in accordance with temperature. By rapidly cooling the display from a cholesteric phase, the material can be solidified in a reflection state. The cholesteric material also has the characteristic during a transition from a solid phase to a cholesteric phase of having of an enthalpy &Dgr;Hch at a substantially constant value during a time when a temperature thereof increases during one of differential thermal analysis and differential scanning calorimetry.
