Abstract
A light adjuster according to which the wavelength dependence of the transmissivity when a voltage is not being applied can be reduced, and a laminated glass containing the light adjuster. The light adjusteris comprised of a single liquid crystal layer, a pair of transparent electrically conductive filmsandhaving the liquid crystal layertherebetween, and a pair of PET filmsandbonded respectively to outer surfaces of the pair of transparent electrically conductive films. The liquid crystal layeris comprised of a transparent polymer filmthat is made of a latex and has a large number of voids therein. Each of the voids is filled with nematic liquid crystalline rod-like molecules, thus forming a liquid crystal capsule. When the light adjusteris in a non-transparent state, the transmissivity exhibits no sudden increase over a wavelength region from 380 nm to 780 nm, the difference between the maximum transmissivity and the minimum transmissivity over this wavelength region being not more than 3%.
