Organic light-emitting device

Abstract

An organic light-emitting device including a substrate; a first electrode on the substrate; a second electrode; an organic layer between the first electrode and the second electrode; and a carbonaceous material-containing layer between the first electrode and the organic layer, wherein the first electrode includes an aluminum (Al)-based reflective layer and a transparent conductive layer sequentially stacked in this order on the substrate, the Al-based reflective layer including a first element and nickel (Ni) and 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).
