Abstract

A liquid crystal composition comprising a liquid crystal and a second substance dispersed therein, the second substance having affinity for the liquid crystal and being composed of particles having a particle size and an aspect ratio of a predetermined value or greater, and a liquid crystal composition comprising a liquid crystal containing electric field sensitive liquid crystal molecules having a positive dielectric anisotropy as the principal component and flat plate-shaped particles having affinity for the liquid crystal being dispersed therein at such a degree of density suitable for effectively forming liquid crystal domains. Also described are a liquid crystal device using the same, a light-controlling element, a recording medium, and a light shutter.
