Abstract
Abstract The present invention is characterized in that is its liquid crystal layer consists essentially of a multi-color highly dielectric liquid crystal composition. The liquid crystal layer may consist of the highly dielectric liquid crystal alone (the highly dielectric liquid crystal being a multi-color in this case) or may use a highly dielectric component as the host liquid crystal component in a so-called "guest-hose type" liquid crystal composition. The liquid crystal display of the present invention is further characterized in that the thickness of the liquid crystal layer is such that the molecules of the highly dielectric liquid crystal can form the helix and/or a pair of substrates are equipped with the color polarizer function.
