摘要： A cholesteric display including a cholesteric liquid crystal, and a dipolar dopant having limited miscibility in the cholesteric liquid crystal is provided. In accordance with another aspect, a process is provided for forming a cholesteric liquid crystal composition by dissolving a dipolar dopant having limited solubility into a cholesteric liquid crystal.

The liquid crystal domains in the liquid crystal composition rotate away from a planar state in the presence of an applied electric field and the degree of rotation is a function of the applied electric field strength. The reflected color is then a function of the applied electric field.

摘要： The present invention relates generally to broadband, reflective circular polarizers and, more particularly, to single layer super broadband, reflective circular polarizers. The polarizers of the present invention are made from a film of material, like a polymer having a cholesteric order, in which a second liquid crystal material, like a nematic liquid crystal, is distributed in a non-linear fashion across the thickness of the film in a plurality of liquid crystal-rich and liquid crystal-depleted sites in the polymer. The resulting polarizers have band passes approaching 2000 nm and reflect circularly polarized light which is either left-handed or right-handed depending on the final spiral structure of the materials utilized. The material of the present invention is fabricated by mixing commercially available polymers having a cholesteric order, a second liquid crystal material and a photoinitiator at a temperature which maintains the mixture in a liquid state. The polymer and the liquid crystal are present in a ratio by weight of 1:2, for example, and the photoinitiator is present in an amount of 0.6% by weight, for example, in the mixture. The heated mixture is then subjected to actinic radiation for a time and at an intensity sufficient to polymerize the polymer or the liquid crystal material or both. Under all polymerizing conditions the segregation rate of the liquid crystal material has to be greater than the polymerization rate of the material being polymerized. The liquid crystal segregates and diffuses, during polymerization, to sites of enlarged pitch in the polymer material from sites of shrunken pitch in the polymer material. Because the actinic light has an exponential intensity distribution due to light attenuation by, for example, light absorption, polymerization occurs in a non-linear fashion resulting in a non-linear distribution of the polymer and the liquid crystal material across the film.
