Abstract:
An organic light-emitting device, comprising:a substrate; a first conductive layer formed over the substrate; at least one layer of a light-emissive organic material formed over the first conductive layer; a dielectric layer formed over the at least one organic layer and having a sheet resistance of at least 1 M&OHgr;/square, wherein the dielectric layer comprises an inorganic oxide, preferably one of an oxide of Al, Ba, Ca, Mg, Ni, Si, Ti or Zr, an oxide of an Al alloy, or an oxide of Alâ€”Li or Alâ€”Mg, and wherein the oxide is sub-stoichiometric; and a patterned second conductive layer formed over the dielectric layer.
