摘要

A PDLC film comprising an optically isotropic, liquid crystal mixture comprising a liquid crystal mixture forming a sub-liquid droplet within a transparent polymer matrix, the liquid crystal mixture comprising a liquid crystal mixture in which one of the refractive indices coincides with a polymer matrix refractive index nM, Characterized in that the transmittance can be changed by application of an electrical voltage, wherein the PDLC film exhibits the following characteristics.;(In the above formula Is the average refractive index of a liquid crystal mixture, defined as:
