An encapsulated liquid crystal layer (16) is patterned by placing a mask (20) into contact with a coated substrate (10). The mask is held against the substrate, for example, by a vacuum, to form a seal. The assembly is submerged in a solvent to dissolve the exposed region of the encapsulated liquid crystal material.
