Abstract

A method of producing an organic light-emitting device comprising a patterned electroluminescent polymer layer arranged between two electrodes such that charge carriers can move between the first and second electrodes an the electroluminescent polymer layer, the method comprising the steps of (a) providing a substrate comprising the first electrode, (b) depositing solid particles comprising the electroluminescent polymer onto selected portions of the surface of the substrate, and (c) securing to the substrate those solid particles comprising electroluminescent polymer particles deposited onto the substrate in step (b) to form the patterned electroluminescent polymer; and (d) forming the second electrode over the surface of the electroluminescent.
