ABSTRACT:
An organic light-emitting display is provided which includes an organic electroluminescent (EL) substrate, a drive layer formed on the substrate, a first electrode formed on the drive layer; organic layers formed on the first electrode, a second electrode formed on the organic layers, and a plurality of pixels. A counter substrate is formed adjacent the organic EL substrate, and a light extraction layer is formed between the substrate and the counter substrate. Each of the pixels includes sub-pixels and is disposed such that an auxiliary electrode of the second electrode is disposed in a part of one of the sub-pixels. The auxiliary electrode is formed on a same level as the first electrode and is connected to a current supply line within the drive layer via a contact hole formed in an inter-layer insulating layer formed over the drive layer.
