    摘要: Provided is an organic light-emitting device, including a first electrode; a second electrode facing the first electrode; an emission layer disposed between the first electrode and the second electrode; a first hole transport layer that is disposed between the emission layer and the first electrode and includes a first compound and a first charge-generation material; a second hole transport layer that is disposed between the emission layer and the first hole transport layer and includes a second compound; a third hole transport layer that is disposed between the emission layer and the second hole transport layer and includes a third compound and a second charge-generation material; and a fourth hole transport layer that is disposed between the emission layer and the third hole transport layer and includes a fourth compound. The first, second, third, and fourth compounds are each represented by Formula 1 or 2:
