A liquid crystal device including a layer of liquid crystal material, and provided on one side of the liquid crystal material layer an array of conductors for generating electric fields therebetween to change the molecular orientation of pixel portions of the layer of liquid crystal material, wherein each pixel portion of the liquid crystal material layer is associated with a respective group of conductors distributed over the respective pixel area for the application of voltages across distances smaller than the pixel dimensions, wherein the conductors and the spacing therebetween within each group are sufficiently small with respect to the thickness of the liquid crystal material layer that each group can be used to generate an electric field that induces through at least a portion of the thickness of the liquid crystal material layer a different molecular orientation pattern that is substantially uniform across the whole area of the respective pixel portion.
