A liquid crystal color display (20) provides a transmitted light output of one or more colors, black, and/or white, as a function of incident light and controlled energization or not of respective optically serially positioned liquid crystal color layers (2, 3, 4) and/or multicolor composite liquid crystal layer(s) in the display. Plural optically serially arranged volumes (21) of operationally nematic liquid crystal material (25) having different optical characteristics, e.g. being dyed with different pleochroic dyes (28), may be selectively aligned or not with respect to an electric field to determine optical output of the device in a subtractive color mode. Exemplary colors of pleochroic dye include yellow, cyan and magenta, and black dye may be used to control saturation or hue. Non-pleochroic dye also may be used in one or more layers of the liquid crystal color display to filter or to color light transmitted therethrough thereby to cooperate with the pleochroic dye to provide a final color output. Additionally, individual pixel-like areas (72, 73, 74) of the liquid crystal color display may be so positioned in proximity to each other to operate in a color additive mode. Techniques for discriminating voltage and/or frequency enable a multicolor response using only a single pair of electrodes. Using cross over liquid crystal material having positive and negative dielectric anisotropy characteristics as a function of frequency of applied signal, multiplex driving of the liquid crystal color display is facilitated.
