Abstract
A method of making a liquid crystal device having a plurality of cells of liquid crystal material, includes the steps of: (a) preparing a first base having a first surface; (b) providing a first phase of a material and a plurality of second phases of at least one liquid crystal material on the first surface, said second phases being spatially dispersed in a first prescribed pattern; (c providing a second base having a second surface, the second surface being substantially in contact with the first and second phases; and (d) solidifying the material of the first phase. The liquid crystal cells are formed of the dispersed liquid crystal materials. The plurality of second phases may include at least a group of liquid crystal materials which exhibits a cholesteric characteristic having a selective reflection wavelength in the visible range and a group of liquid crystal materials which exhibits a cholesteric characteristic having a different selective reflection wavelength in the visible range.
