Beschreibung
Zusammenfassung:	An organic light-emitting diode includes: a first electrode; a second electrode facing the first electrode; and an organic layer disposed between the first electrode and the second electrode. The organic layer includes a light-emissive layer that includes a dopant material including an organometallic compound represented by Chemical Formula 1, and a host material including a mixture including a compound represented by Chemical Formula 2 and a compound represented by Chemical Formula 3. The organic light-emitting diode may have excellent or desirable light-emitting efficiency and lifespan. Also shown is an organic light-emitting display device comprising a substrate, a diving element and an organic light-emitting diode as above disposed on the substrate and connected to the driving element.
