摘要：
An organic light-emitting diode includes a first electrode; a second electrode facing the first electrode; an emission layer (EML) between the first electrode and the second electrode; a first charge generation layer between the EML and the first electrode and including a first compound and a first charge generation material; a first layer between the EML and the first charge generation layer and including a second compound; a second charge generation layer between the EML and the first layer and including a third compound and a second charge generation material; a second layer between the EML and the second charge generation layer and including a fourth compound; and a buffer layer between the EML and the second layer. The first and third compounds each independently includes a compound represented by Formula 1, and the second and fourth compounds each independently includes a compound represented by Formula 2.
