摘要:
An optical element includes a pair of a transparent substrate and a back substrate which face each other with a predetermined gap by a spacer, and, a pair of the first electrode and the second electrode, and a periodic structural body as an optical composition for a multi-color display and an electrolytic solution are disposed within the gap of the transparent substrate and the back substrate. Metal ions contained in the electrolytic solution are deposited as metal atoms onto the periodic structural body of the optical composition for a multi-color display, to change a structural color of the periodic structural body. Display that can display a color and has a memory property can be obtained.

An optical element comprises a molded body of a composition of a cross-linked macromolecular liquid crystal and a resin. An optical element composed of a macromolecular liquid crystal composition where the granules of the cross-linked macromolecular liquid crystal are dispersed into the resin as a binder is preferable. The element can be made by preparing in advance granules of the cross-linked macromolecular crystal liquid by a physical or chemical crushing manner, dispersing the granules in the binder, and then molding it.

摘要:
A light modulation device with high density, high sensitivity, and excellent stability while having a simple construction and a non-destructive memory reading method using the same are disclosed. The light modulation device comprises a high polymeric liquid crystal film comprising a uniaxially orientated side chain type high polymeric liquid crystal containing a photochromic compound, and it modulates light in the wavelength region in which the photochromic compound has no absorption by making use of a change in refractive index anisotropy of the high polymeric liquid crystal film which has been caused by photoisomerization of the photochromic compound. The device is useful as a stable and high-density optical computing device or an erasable optical memory material.

A reversible display medium comprising substrate 1 having thereon recording layer 2 containing a side chain type high polymeric liquid crystal capable of repeatedly and reversibly switching between a transparent state and a light-scattered state by the action of heat, an electrical field or a magnetic field, wherein said side chain type high polymeric liquid crystal is a copolymer comprising at least one liquid crystal monomer unit and at least one non-liquid crystal monomer unit having a hydrogen bond-forming substituent, e.g., a hydroxyl group, a carboxyl group, a sulfonic group or a phosphoric group. The display medium is excellent in durability on repeated use, heat sensitivity, display contrast, and record preservability.
