摘要： An organic light-emitting diode including: 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-emitting 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.
