Abstract
An organometallic complex for a light emitting layer includes a heterocyclic ligand and a bivalent metal bonded to the heterocyclic ligand, wherein the heterocyclic ligand includes a plurality of linked ring structures that include a total of at least 17 carbon atoms and 1 heteroatom, and the linked ring structures have substantially parallel planes.
