| 1. A transparent display comprising:
an electrically-controlled polarization modulating material;
an addressing backplane that changes the polarization of light and electrically controls the polarization modulating material;
and
an internal polarization isolator to isolate the desired polarization effects of the polarization modulating material from
the undesired polarization effects of the addressing backplane, the polarization isolator including a linear polarizer formed
by patterning a one-dimensional wire grid array of closely-spaced metal lines on the electrically controlling side of the
addressing backplane.
