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.

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, said 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, wherein said non-liquid-crystal monomer component is in a range of 0.1 to 50% by weight based on a total amount of said liquid-crystal monomer component and said non-liquid-crystal monomer component and the copolymer has a weight-average molecular weight between 1,000 and 1,000,000.
