    摘要: A component has a substrate (1) made of a transparent material, for example glass. On this layer (1), there is a linear polarizer (2) on which there is a layer (3) of a photo-oriented polymer network (PPN)(nullLPP) which is oriented in locally varying fashion via its surface which covers the substrate. The layer (3) is adjoined by an anisotropic layer (4) of cross-linked liquid-crystal monomers. This layer (4) then has a molecular arrangement whose orientation is defined by the underlying orientation layer (3). The layer (4) will have been photocross-linked by exposure to a suitable wavelength of light, with the result that the molecular orientation defined by the PPN layer (3) is fixed. The element denoted as a whole by 7, can then be used as an optical component which is protected against forgery, it being possible for the orientation pattern of the liquid-crystal layer or the optical information stored therein to be made visible by means of an external polarizer (5), for example.

    摘要: An optical component having a hybrid layer structure includes an orienting layer, a further layer in contact with the orienting layer and incorporating a cross-linked liquid crystalline monomer and at least one additional orienting layer on top of the liquid crystalline layer, and preferably includes one additional cross-linked liquid crystalline monomer. The layers have different functions, such as orienting or retarding. At least one of the orienting layers should be a photo-orientating polymer network layer, or have locally varying orienting pattern. These optical components are useful in transmittance and reflective liquid crystal displays, such as rotation cells, STN cells, ferroelectric cells, and cells having an addressable active matrix. Such cells are useful in optical and integrated optical devices, and may be used for safeguarding against counterfeiting and copying in transmission.
