Abstract
A light valve film forming a light-modulating element of a light valve, the film comprised of a cross-linked polymer matrix with a plurality of droplets of a liquid light valve suspension distributed therein. The film has a phase ratio: % particle number value calculated by the formula: In one embodiment the light valve film has a relatively low visible transmittance in the unpowered Off state such that the film has a % T of <0.05 and a ΔT of >42%. In another embodiment the light valve film has a relatively high visible transmittance in the On state such that the film has a % T of >70% and a ΔT of >57%.
