ABSTRACT:
A display device composed of:(a) a cathode;(b) an anode;(c) a luminescent region between the cathode and the anode; and(d) an optional region adjacent to the cathode or the anode, wherein the device includes a plurality of metal-organic mixed layers disposed at one or more of the cathode, the anode, the luminescent region and the optional region, wherein each of the metal-organic mixed layers includes:(i) an inorganic metal containing material, and(ii) an organic material.
