ABSTRACT:
A display device includes a substrate having at least one light-emitting element. The light-emitting element includes one electrically-continuous electrode formed over the substrate. A separator is located on the electrically-continuous electrode, dividing the electrically-continuous electrode into at least first and second separate electrode portions that remain electrically continuous. A transparent layer is located over the first electrode portion, while separated from the second electrode portion. A light-emitting layer is formed over the transparent layer and the second electrode portion. A second electrode is formed over the light-emitting layer. The first electrode portion, the transparent layer, the light-emitting layer, and the second electrode comprise a first optical cavity having a first optical path length. The second electrode portion, the light-emitting layer, and the second electrode comprise a second optical cavity having a second optical path length different from the first optical path length.
