<p>This invention provides a liquid crystal projection display, comprising (a) light source means (82) for producing light; (b) image forming means (91, 92, 93) comprising plural pixel elements (91a, 92a, 93a), each pixel element comprising liquid crystal material dispersed in plural volumes in a containment medium and being independently operable to primarily scatter light incident thereon in the absence of a sufficient electric field and to primarily transmit light incident thereon in the presence of a sufficient electric field, the liquid crystal composition including a pleochroic dye which, in the absence of the sufficient electric field, preferentially absorbs light in the spectral region in which the amount of light scattering by the image forming means is lowest and which, in the presence of the sufficient electric field, transmits such light, to thereby balance the color of the light scattered or transmitted by the image forming means; and (c) lens means (94) for projecting light transmitted by the image forming means onto a screen.</p> |
