1. A display comprising:
a substrate;
an array of pixels that includes first and second organic light-emitting diode pixels, wherein the first organic light-emitting diode pixel includes a first patterned electrode on the substrate and wherein the second organic light-emitting diode pixel includes a second patterned electrode on the substrate;
at least two layers on the substrate that are interposed between the first and second patterned electrodes, wherein the at least two layers comprise a first layer that is formed on the first patterned electrode and that has an edge surface at a non-orthogonal angle relative to an upper surface of the first patterned electrode, wherein the at least two layers comprise a second layer formed over the first layer, wherein the first layer is interposed between the second layer and the first patterned electrode, and wherein the edge surface is not directly overlapped by the second layer; and
a conductive layer formed over the at least one layer that has a first portion that forms part of the first organic light-emitting diode pixel and a second portion, wherein the second portion is electrically isolated from the first portion by a void that is at least partially defined by an undercut in the at least one layer.
