The invention provides an improvement in light modulating devices employing birefringent liquid crystal interspersed in isotropic polymer. A polarizer disposed on a surface of the liquid crystal device produces haze-free viewing for all viewing angles in the plane orthogonal to the polarization direction...http://www.google.com.au/patents/US5264950?utm_source=gb-gplus-sharePatent US5264950 - Light modulating device with polarizer and liquid crystal interspersed as spherical or randomly distorted droplets in isotropic polymer
