Abstract

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 provide 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) provided 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.
