A liquid crystalline diffractive light valve for use in a diffractive projection system. The liquid crystal cell includes substrates treated to provide alternating stripes which cooperate with the liquid crystal to form liquid crystal domains extending across the thickness of the cell that will produce a 180 DEG phase difference in light emerging from adjacent domains, irrespective of the polarization of incident light.
