Abstract
A method for forming a patterned layer of a light-emissive material on a substrate, comprising the steps of providing a holed layer on the surface of the substrate, the holed layer being permanently attached to the substrate and defining a plurality of holes through which the underlying substrate is exposed, and applying a light-emissive material to the surface of the holed layer opposite the substrate and displacing the light-emissive material in fluid form across the surface of the holed layer so as to selectively deposit the material only in the holes of the holed layer.
