A display sheet having polymer dispersed liquid crystals including a substrate; a state changing layer disposed over the substrate and defining first and second surfaces, such state changing layer having the polymer dispersed liquid crystals having first and second optical states, which can change state; and a first transparent conductor disposed on the first surface of the state changing layer. The display sheet also includes a second conductor on the second surface of the state changing layer and has a composite structure of at least two layers of different materials wherein the composite structure absorbs light and is electrically conductive so that when a field is applied between the first and second conductors, the liquid crystals change state.
