An optical body includes a) first particles comprising a first cholesteric
liquid crystal material and b) a second cholesteric liquid crystal
material. The first particles and the second cholesteric liquid crystal
material form a structure where the first cholesteric liquid crystal
material has a pitch that is different than the second cholesteric liquid
crystal material. In one example, the second cholesteric liquid crystal
material is in the form of second particles. In another example, the
first particles are dispersed in a matrix of the second cholesteric
liquid crystal material. In other examples, the optical body has more
than one layer. In addition, one or more additional cholesteric liquid
crystal materials can be used in the optical body. These optical bodies
can be used as a reflective polarizer and can be used in a display.
