Abstract
Light-control devices of the type having field-orientable, light-control elements supported in a solid elastomeric matrix are constructed in a manner providing improved uniformity in light-control and, in image display uses, improved resolution and contrast. Features of the improved construction include predetermined physical characteristics such as size, shape and/or location of the light-control elements within the matrix. Various methods for achieving such constructions include the steps of forming the desired array of elements and disposing the array in the matrix with relative positions of the elements maintained.
