Claims28
A liquid crystal composition, comprising:
- at least two gelling agents;
- and
- a liquid crystal showing a liquid crystal phase at room temperature.
A liquid crystal composition, comprising:
- at least two self-organizing gelling agents;
- a nematic liquid crystal showing a cholesteric phase at room temperature, and
- a chiral material;
- a ratio of the gelling agent highest in content being 90% by mass or less with respect to the total amount of the gelling agents contained, and
- a sol-gel transition temperature being lower than liquid crystal/isotropic phase-transition temperature.
