1. An elastomeric light valve, comprising:

  • a substrate having a surface;

    a multiplicity of pixels formed on said substrate surface, each pixel comprising interdigitated first and second sets of pixel electrodes;

    a layer of silicone elastomer gel disposed over said substrate surface and said first and second sets of pixel electrodes;

    at least one self-supporting pellicle disposed substantially completely over said gel layer and formed of a silicone/polycarbonate material;

    a conductive layer disposed substantially completely over and adhering to said at least one pellicle, a surface of said conductive layer closest to said substrate being chemically compatible with said at least one pellicle, and a surface of said conductive layer farthest from said substrate being a specular exposed surface;

    means for selectively applying control voltages to said first and second sets of pixel electrodes; and

    means for selectively applying a bias voltage to said conductive layer to improve the light valve deformability.
