摘要： An optical component in the form of an identification element (such as for counterfeit protection or copy protection) includes an optically anisotropic layer comprising regions of different optical axes that is arranged over a reflector. The anisotropic layer may be implemented with a liquid crystal polymer in which the orientation of the liquid crystals is different in different areas. Such an orientation pattern is initially hidden from a viewer, but becomes visible by means of an additional polariser. To improve the visual appearance of the identification element, a white light hologram may be used for the reflector.

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： Known liquid crystal cells have a nematic liquid crystal configuration and, in accordance with this configuration, are referred to as TN or STN cells. It is true that such cells are adequate for many applications. However, their image quality is dependent to a very great extent on the user's angle of view. Furthermore, TN and STN cells require a continuously applied signal voltage if it is intended to display or store information on one. Bistable liquid crystal cells having a ferroelectric, chiral smectic liquid crystal layer do not have these disadvantages of nematic display cells. However, the commercial production of such bistable display cells has scarcely become established to date. This is in particular because they are not very suitable for reliably storing information or do not permit absolutely equivalent switching between the two bistable positions of the director. The invention now proposes a novel, bistable liquid crystal cell which avoids precisely these disadvantages. Starting from the SBFLC display cell disclosed in EP-A 0 405 346, the display cell according to the invention is distinguished in that its liquid crystal layer contains polymerized molecules and is formed, by treatment with light and an alternating electric field, in such a way that it has two equivalent, bistable switching states.
摘要翻译：已知的液晶单元具有向列型液晶结构，根据该结构，称为TN或STN单元。这样的电池确实适用于许多应用。然而，他们的图像质量在很大程度上取决于用户的观点。此外，如果TN和STN单元旨在将信息显示或存储在一个上，则需要连续施加的信号电压。具有铁电手性近晶液晶层的双稳态液晶单元不具有向列型显示单元的这些缺点。然而，迄今为止，这种双稳态显示单元的商业生产几乎没有建立。这特别是因为它们不太可靠地存储信息，或者不允许在导演的两个双稳态位置之间进行绝对等效的切换。本发明现在提出了一种新颖的双稳态液晶单元，其精确地避免了这些缺点。从EP-A 0 405 346中公开的SBFLC显示单元开始，根据本发明的显示单元的特征在于，其液晶层包含聚合分子，并且通过用光和交变电场处理形成在这样的它具有两个等效的双稳态切换状态。

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.
