Abstract
Monomers with photopolymerization characteristics and an initiator for polymerization are added to a liquid crystal composition having a ferroelectric liquid crystal phase (S5). In a state (S6) where coexist two domains which differ from each other in directions of molecular major axes in the ferroelectric liquid crystal phase, light is projected to the liquid crystal layer to form a polymer reticulate structure therein (S7). As a result, this state is made a stable one and the liquid crystal shows macroscopic switching behaviors among two states causing dark and bright displays respectively, and the above-described state causing halftone display.
