Abstract: A method of fabricating an organic electroluminescent display includes: forming a plastic layer on a substrate including a first pixel region; patterning the first plastic layer to form a first opening in the first pixel region; forming a first organic light emitting layer on the first plastic layer having the first opening; and removing the first plastic layer from the substrate to form a first organic light emitting pattern in the first opening.

Abstract: An organic light emitting display device includes a substrate including a pixel region, and a first electrode over the substrate and in the pixel region. An auxiliary electrode is disposed over the substrate, and is spaced apart from the first electrode and disposed in between the pixel region and another pixel region. A second electrode is placed over the first electrode and the auxiliary electrode, and an organic layer is disposed between each of the first electrode and the second electrode, and the second electrode and the auxiliary electrode. A conductive member is placed between the auxiliary electrode and the second electrode and electrically connects the second electrode to the auxiliary electrode.

Abstract: An organic electroluminescent device includes a substrate having a plurality of pixel regions defined thereon; and, in each pixel region, at least first, second and third light emitting elements formed on the substrate, each of the first, second, and third light emitting elements including a lower first electrode, an upper first electrode, an organic-light emitting layer, and a second electrode. A ratio of a thickness of the upper first electrode to a thickness of the organic light emitting layer in the first light emitting element is 1:3 to 1:4. A ratio of a thickness of the upper first electrode to a thickness of the organic light emitting layer in the second light emitting element is 1:2.5 to 1:3. A ratio of a thickness of the upper first electrode to a thickness of the organic light emitting layer in the third light emitting element is 1:1.5 to 1:2.
