ELECTRO-OPTICAL COMPOSITION

摘要

A composition which exhibits switchable electro-optical properties and is soft solid at 25 DEG C comprises a dispersion of particles in a liquid crystalline material. The particles may be substantially spherical particles of a polymer such as PMMA having a size of about 100 to 1000 nm. The composition may be produced by forming a homogenous dispersion of particles in a liquid crystalline material at a temperature above the isotropic-nematic transition temperature of the material and then cooling the dispersion. The composition has the advantages of improved hanlding and flexibility and may be used in electro-optical devices such as flat panel displays.
