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.

摘要： By combination of a hybrid layer formed from an orienting layer and a layer of a cross-linked liquid crystalline monomer with a reflector, and by appropriate local structuring of the molecule orientation, an optical pattern is obtained which cannot be copied using conventional photocopiers. This pattern is useful as means for protecting documents, such as banknotes, credit cards, and the like, from being copied, and can be detected by manually or automatically, operated optical reading devices.

摘要： A liquid crystal cell comprising a cholesteric liquid crystal (3) between parallel plates (1, 2) as used e.g. for optical filters. The previously unavoidable interference through faulty disinclination is eliminated in that the cholesteric liquid crystal is mixed with a nematic or smectic liquid crystal material having negative dielectric anisotropy and the cell is subjected to an electric field directed at right angles to the plates.

摘要： Sub-micron-structured (nanostructured) polymer film or coatings are made by coating a substrate with a mixture of materials. One of the materials is removed using a selective solvent, leaving pores or other nanostructure. The substrate may be grooved, providing a competing nanostructure. The coating may act as an antireflective coating, optical retarder, optical diffuser, or orientation layer.

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)(-LPP) 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 clement, 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： A method of imparting a property to a material, the property being that cross-linkable monomeric or pre-polymeric liquid crystal molecules which may be placed on the layer would adopt preferred alignment. The method comprises exposing the material to unpolarised or circularly polarised radiation from an oblique direction, wherein the material is, for example, cross-linked by the irradiation, allowing monomeric or pre-polymeric liquid crystal molecules applied to or mixed with the exposed material to adopt the preferred alignment and while aligned cross-linking them. The invention also relates to LCD elements incorporating a preferred alignment.
