Abstract

A light-emitting device having a first electrode, a second electrode, and an emissive layer (EML) in electrical contact with the first electrode and the second electrode. A charge transport layer (CTL) is positioned between the EML and the second electrode, with the second electrode being an ultrathin transparent metal layer of less than five nanometers, and including an auxiliary electrode metal grid formed by wet etching. The ultrathin transparent metal layer is positioned between the CTL and the auxiliary electrode metal grid, and the ultrathin metal layer is preferably a metal with an etchant selectivity such that it is unaffected by the wet etching of the auxiliary electrode.
