A multi-color liquid crystal display has a one-dimensional or two-dimensional array of at least one display cell, with a plurality of different liquid crystal host/guest dichroic dye compositions in each cell. Each of the different liquid crystal compositions may be provided within separate microcapsules, with the totality of micro-capsules being blended to provide the total composition filling the cell volume or dielectric spacers may be utilized to divide the volume of each display cell into a like plurality of subvolumes, each containing a different liquid crystal material. Liquid crystal hosts of substantially-constant or variable dielectric anisotropy magnitude and polarity are selected to cause different ones of the plurality of compositions within a cell to switch between transmission and absorption of various visible-wavelengths regions as the frequency and amplitude of an electric field within the cell is varied by control electronics of a display system.
