| description | PROBLEM TO BE SOLVED: To provide a highly efficient light absorbing layer or the like. SOLUTION: A display sheet having polymer dispersed liquid crystals relating to this invention comprises: (a) a substrate; (b) 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 the state; (c) a first conductor disposed over the first surface of the state changing layer; (d) a second conductor on the second surface of the state changing layer so that when a field is applied between the first and second conductors, the liquid crystals change the state; and (e) a nonconductive field spreading layer having polymer dispersed sub-micron particles disposed between the state changing layer and the first conductor to provide a change of the state in the state changing layer outside of areas between both conductors in response to the field applied between the first and second conductors which changes the state of the liquid crystals.
