Abstract
A security device includes a plurality of diffractive surface elements arranged on a carrier element. Each individual diffractive surface element can have a three-dimensional surface structure. A portion of the plurality of the diffractive surface elements can form a first surface element group. An orientation of the diffractive surface elements in the first surface element group can be matched to each other wherein they make a first point of an associated symbol to be represented visible. A plurality of additional surface element groups each can make a respective additional point of the symbol to be represented visible. The symbol can include a sum of all points represented by the first surface element group and the plurality of additional surface element groups. A movement of the symbol can be perceived by the continuous change in an angle of incidence of the light or an observation angle.
