Abstract

An organic light-emitting device, comprising: a substrate (1); a first conductive layer (3) formed over the substrate (1); at least one layer (5) of a light-emissive organic material formed over the first conductive layer (3); a barrier layer (7) formed over the at least one organic layer (5) which acts to protect the at least one layer of organic material; and a second conductive layer (9), preferably a patterned sputtered layer, formed over the barrier layer (7).
