Abstract:
1. An organic light-emitting device, comprising: a substrate; a first electrode on the substrate; a second electrode; an organic layer between the first electrode and the second electrode, the organic layer including an emission layer; and a first layer including a cyano group-containing compound and a hole transporting compound, the first layer being between the first electrode and the emission layer and a distance between the first layer and the emission layer being about 50 Å or greater, wherein: the first electrode includes an Al-based reflective layer and a transparent conductive layer sequentially stacked on the substrate, the Al-based reflective layer including a first element and nickel (Ni), the first element includes at least one of lanthanum (La), cerium (Ce), praseodymium (Pr), promethium (Pm), samarium (Sm), europium (Eu), gadolinium (Gd), terbium (Tb), dysprosium (Dy), holmium (Ho), erbium (Er), thulium (Tm), ytterbium (Yb), and lutetium (Lu), and the hole transporting compound includes a compound represented by Formula 41 or 42 below: wherein R R Ar n, m, a, and b are each independently an integer from 0 to 10; R Q wherein n groups of Ar
