Complementary color liquid crystal display

A liquid crystal color device, comprising

• at least one pel means for affecting light incident thereon by transmitting and/or filtering such light to produce output light,
• said at least one pel means including at least two color subsets,
• one subset including a first color and the complementary color of that color, and the other including a second color and the complementary color of that color,
• said subsets being responsive to an input to alter light transmitting or absorbing properties thereof,
• the color and complementary color of each subset being arranged in optically subtractive relation,
• said subsets being arranged in optical additive relation such that the optical outputs from different subsets within a pel means combine additively, and
• said one subset being optically cooperative with said other subset selectively to contribute the color of said second color of light in the output light of said pel means.

A method of displaying a multicolor output, comprising

• selectively filtering one portion of multicolor incident light by a first controllable filter of a first color and the complementary color thereof,
• selectively filtering another portion of multicolor incident light by a second controllable filter of a second color and the complementary color thereof,
• wherein the complementary color of the first color includes at least one color component that is the same color as the second color, and
• selectively using said at least one color component from the complementary color of the first color to contribute said same color to the output.
