A light valve comprising: a film having two opposed outer surfaces; a first layer of a polymeric interlayer material upon at least a portion of each opposed outer surface; a first pair of substrates, one adhered to the interlayer material upon the first outer surface of the light valve film and second adhered to the interlayer material upon the second outer surface of the light valve film, these substrates formed from plastic; a second layer of polymeric interlayer material applied to at least a portion of an outer surface of each one of the first pair of substrates; and a second pair of substrates, one adhered to the interlayer upon the outer surface of one of the first pair of substrates and a second adhered to the interlayer material on the outer surface of a second of the first pair of substrates, the second pair of substrates formed from glass.
