Security element and security document

摘要

The invention relates to a security element (2), in particular in the form of a multi-layer flexible film body, with a top side facing an observer and a back side facing away from the observer, as well as a method for the production thereof. The security element (2) has one or more light-emitting elements arranged in a first area (30) of the security element which radiate light when activated and in particular are formed in each case of a self-luminous, electrically operated, display element. The security element (2) has, in the first area (30), one or more transmissive diffraction structures. The one or more transmissive diffraction structures are arranged such that at least a part of the light radiated by the activated one or more light-emitting elements transmits through at least one partial area of the transmissive diffraction structures.

1. A security element in the form of a multi-layer flexible film body, with a top side facing an observer and a back side facing away from the observer, wherein the security element has one or more light-emitting elements arranged in a first area of the security element which radiate light when activated and in each case are formed of a self-luminous, electrically operated, display element, wherein the security element has, in the first area, one or more transmissive diffraction structures, wherein the one or more transmissive diffraction structures are arranged such that at least a part of the light radiated by the activated one or more light-emitting elements transmits through at least one partial area of the transmissive diffraction structures, and
wherein one or more of the one or more transmissive diffraction structures in each case is formed of a plurality of elements, wherein the elements in each case have at least one element surface arranged substantially parallel to a base plane, the elements are arranged offset relative to each other in relation to at least one first direction running parallel to the base plane and the elements neighboring element surfaces are spaced apart in a direction perpendicular to the base plane according to a variation function dependent on the at least one first direction, by a distance or a multiple of the first distance, wherein the variation function is a periodic function and in each period of the variation function the element surfaces of at least two elements following on from each other in the at least one first direction are spaced apart from each other by the first distance.
