摘要：The invention relates to a security element for producing value documents,such as banknotes, checks, or the like, said security element having: a dielectric substrate(1); a first line grid structure (2) which is embedded into the substrate (1), said structureconsisting of multiple first grid webs (3) which run along a longitudinal direction, whichare arranged on a plane (L), and which consist of metal or a semiconductor; and a secondline grid structure (6) which is embedded into the substrate (1), said structure consistingof second grid webs (7) which run along the longitudinal direction, and which consist ofmetal or a semiconductor, wherein the second line grid structure is located above thefirst line grid structure (2) with respect to the plane (L). Each first grid web (3) has a width(b), and the webs lie next to one another at a distance (a) from one another such that firstgrid gaps (4), which runs along the longitudinal direction and which have a width thatcorresponds to the distance (a), are formed between the first grid webs (3). The secondline grid structure (6) is inverted with respect to the first line grid structure (2) and isdisplaced by half a period with respect to the first line grid structure (2) such that thesecond grid webs (7) lie above the first grid gaps (4), and second grid gaps (8), which areproduced between the second grid webs (7), lie above the first grid webs (3) in a plan viewof the plane. The width of the first grid webs (3) and the second grid gaps (8), the width

of the second grid webs (7) and the first grid gaps (4), and a thickness (t) of the first gridwebs (3) and the second grid webs (7) are each less than 300 nm.
