    摘要： A method and a device check a security element of a security document. The security element contains at least one particulate substance with electroluminescent properties and at least one field suppression element. The method includes applying an electric excitation field to the security element, generating an optical image of at least one region of the security element after or during the production of the electric excitation field, and detecting local intensity maxima in the optical image. The security element is verified if a number of local intensity maxima present at different image positions is greater than or equal to a specified number, the number being at least two.

    摘要： The invention relates to a security element (1). The security element (1) has a viewing side and a back side that is opposite the latter. The security element comprises at least one luminous layer (2) that can emit light (20), and at least one mask layer (4) that, when the security element (1) is viewed from the viewing side, is arranged in front of the at least one luminous layer (2). The at least one mask layer (4) has at least one opaque region (5) and at least two transparent openings (41, 42). The at least two transparent openings (41, 42) has a substantially higher transmittance than the at least one opaque region (5) in respect of light (20) emitted by the at least one luminous layer (2), preferably a transmittance that is at least 20% higher, particularly preferably a transmittance that is at least 50% higher.

    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.
