Document Type and Number:
Japanese Patent JPH07508107
Kind Code:
A
Abstract:
A liquid crystal projection display, having (a) a light source for producing light of at least two different primary colors; (b) an imaging element corresponding to each primary color light produced by the light source, each imaging element comprising plural pixel elements, each pixel element comprising liquid crystal composition dispersed in plural volumes in a containment medium and being independently addressable 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; and (c) a lens for projecting light transmitted by each imaging element onto a screen; the liquid crystal composition in the pixel elements of the imaging element corresponding to the primary color light of longest wavelength including a pleochroic dye of a color complementary to the primary color light of longest wavelength, which pleochroic dye preferentially absorbs incident light which has not been scattered by the liquid crystal material in the absence of the sufficient electric field and transmits incident light in the presence of the sufficient electric field.
