Abstract
A light-modulating electrically responsive sheet including a substrate and electrically conductive layer formed over the substrate. The sheet further includes a light-modulating layer disposed over the electrically conductive layer and including at least one dispersible light-modulating material and coalescence limiting material into which the dispersible light-modulating material(s) is provided so that such dispersible light-modulating material coalesces to form a limited coalesced material having a set of domains each having a set of domains that exhibit different electrically responsive optical states.
