Abstract
A method in which a liquid is sprayed through a nozzle to form minute droplets of substantially uniform size. These uniform droplets are sprayed into and frozen by a refrigeration medium, such as liquid nitrogen, to form uniform diameter frozen particles. The frozen particles are ejected onto the surface of a substrate used in a liquid crystal display device to orient the liquid crystal material applied to the surface.
