Abstract

Fiber-shaped metal-containing spacing elements having a well-defined diameter of less than 100 mu m for spacing two plates in an indicia display device, such as a liquid crystal cell, are produced by providing a wire composed of a metal selected from the fourth to sixth adjacent groups of the Periodic Chart of the Atoms, converting the peripheral surface layer of such wire into a brittle metallic compound and breaking-up the so-treated wire into desired size individual spacing elements. By utilizing metal wires, an exact diameter dimension can be attained and by chemical conversion of the wire surface, the produced metal wire loses its ductility and can be easily broken-up into desired size elements. Spacing elements of the invention are useful in all types of indicia display devices particularly in multiplex liquid crystal display devices.
