Abstract
A security element for a security paper, value document or the like, having a carrier which has a reflective areal region which is divided into a multiplicity of reflective pixels. The area of each pixel is smaller than the area of the reflective areal region by at least one order of magnitude. Each pixel has at least one reflective facet which is formed in a surface of the carrier, and the at least one reflective facet reflects light incident along a predetermined direction on the areal region directionally in a reflection direction predefined by the orientation of the facet. The orientations of the facets of different pixels have a substantially random variation over the reflective areal region.
