Abstract: An optically variable element, in particular a security element and/or a decorative element, preferably for security documents, wherein the optically variable element has at least one pixel array having two or more pixels, wherein one or more pixels of the two or more pixels have one or more structures, and wherein one or more structures of the one or more structures project, diffract and/or scatter incident electromagnetic radiation at one or more solid angles. A security document, in particular comprising one or more optically variable elements, a method for producing an optically variable element, preferably a security element and/or a decorative element, preferably for security documents, as well as a method for producing a security document, preferably comprising one or more layers, preferably comprising one or more optically variable elements.

Abstract: A functional element 2 including at least one first relief structure 13 in at least one first area 21 and at least one metal layer 12 arranged in at least one subarea of the at least one first relief structure 13 and optionally a preferably polymeric dielectric layer on the side of the metal layer 12 which faces the observer, wherein the at least one first relief structure 13 has a periodic variation of elevations and depressions in the x- and y-direction, wherein the elevations succeed each other with a grating period Λ which is smaller than a wavelength of the light visible to the human eye, wherein the minima of the depressions define a base surface and wherein the at least one first relief structure 13 has a relief depth t. Further, a method for producing or modifying a surface and a product 1 having such a functional element 2.
