Abstract
In an organic EL device, a hole injection electrode is formed on a glass substrate, and a hole injection layer, a hole transport layer and a luminescent layer are formed in turn on the hole injection electrode. An electron injection electrode is formed on the luminescent layer. The luminescent layer includes an organic iridium compound composed of a combination of a quinoline derivative and iridium. This organic iridium compound can emit red-orange light via a triplet excited state.
