POLYMERISED LC FILMS WITH VARYING THICKNESS

摘要

The invention relates to a film of polymerised liquid crystal (LC) material having at least two regions with different thickness, for example in the form of a surface grating, to a process of preparing such a film, to a polymerisable LC material used for the preparation of such a film, and to the use of the film in LC displays or other optical or electrooptical components or devices, for decorative or security applications.
