ABSTRACT:
A reversible display medium capable of repeatedly exhibiting a transparent state and a light-scattering state by an action of at least one of heat, electric field, and magnetic field, the medium comprising a substrate having thereon a recording layer comprising a side-chain high molecular weight liquid crystal, which is a copolymer comprising at least a liquid-crystal monomer component and a non-liquid-crystal monomer component having a substituent capable of making a hydrogen bond.
