The invention relates to a film (2), in particular an embossing film, laminating film or sticker film, as well as an optical security element. The film (2) has a carrier layer (21) and a replication layer (23). The film further comprises a layer (24) of a liquid crystal material applied to the replication layer. In the surface of the replication layer facing the layer of a liquid crystal material, a diffractive structure (27) for orientation of the liquid crystal material is impressed, which has at least two partial regions with different orientation directions of the embossed structure. |
