    摘要: The invention relates to a security element (1), to a security document (2) having at least one security element (1), to a transfer film (3) having at least one security element (1), and to a method for producing a security element (1), wherein the security element has at least one layer (11) having an electrically controlled variable optical effect. According to the invention, the at least one layer (11) having an electrically controlled variable optical effect contains liquid crystals (12) that can be oriented in an electric field, and the layer (11) having an electrically controlled variable optical effect contains rod-like dye molecules (13), and the orientations of the longitudinal axes (14) of the rod-like dye molecules (13) can vary depending on the orientations of the longitudinal axes (16) of the spatially adjacent liquid crystals (12) that are orientable in the electric field, and/or wherein the liquid crystals (12) that are orientable in the electric field are such that the liquid crystals (12) that are orientable in the electric field act simultaneously as dye molecules.
