The invention relates to a security element (20) for security papers, valuable documents, and the like, comprising a carrier film (22) which is provided in at least one portion with an alignment layer (24) with an optical effect which can largely be disregarded, and with an aligned motif layer (30) arranged on the alignment layer (24), based on a liquid crystal material which has at least two areas (32, 34), forming a motif with different orientation of the liquid crystal material. According to the invention, the alignment layer (24) is formed from a cholesteric liquid crystal material, and the layer thickness of the alignment layer (24) is chosen such that its optical effect can be largely disregarded. In addition, the different orientation of the motif layer areas (32, 34) is caused by a different effective height of the helical structure of the cholesteric liquid crystal material of the alignment layer (24). |
