A method for making an optical element from patterned liquid crystal films by placing a radiation-curing liquid crystal on an aligning function substrate surface, radiating selectively a portion of the liquid crystal film partially to cure it, contacting the partially cured film with an organic solvent to remove the uncured portion of the film and form a pattern in the film, and applying another radiation-curing liquid crystal to a surface of the first film exposed by removing the uncured portion, thereby forming and patterning the second liquid crystal film. The solvent does not dissolve the substrate surface.
