A device for illuminating, as well as enhancing contrast of, reflective dichroic liquid crystal displays utilizes a polarizing member extending across the thickness of a wedge illuminator. The light emitted from the wedge illuminator is polarized in a single direction, perpendicular to the elongated direction of the dichroic dye molecules in the light-transmitting areas of the display cell.
