The invention relates to a birefringent RM lens obtainable from a polymerizable liquid crystalline medium consisting of a polymerizable liquid crystalline component A, consisting of one or more polymerizable mesogenic compounds, and a non-polymerizable component B, consisting of one or more non-polymerizable compounds and to the use of such birefringent RM lenses in electro optical devices, such as liquid crystal displays (LCDs) or other optical or electrooptical devices, for decorative or security applications.
