Abstract
An optically variable representation element with a reflective surface region generates a respective three-dimensional representation for at least two different observation directions. The reflective surface region contains a respective multiplicity of reflective facets in a first and a second partial region, which at least partially overlap one another. The reflective facets are oriented such that the facets in the first partial region generate a first three-dimensional representation from the first observation direction and the facets in the second partial region generate a second three-dimensional representation from the second observation direction. The facets of the reflective surface region are provided at least regionally with sub-wavelength structures which generate the different colors of the three-dimensional representations in the overlap region.
