Abstract: An organic light-emitting device including: a first electrode; a light-emitting layer disposed on the first electrode; a second electrode disposed on the light-emitting layer; and an electron transport region disposed between the light-emitting layer and the second electrode. The light-emitting layer includes a first doped region and a second doped region disposed between the first doped region and the electron transport region. The first doped region includes a host material and a dopant material, and the second doped region includes the host material, the dopant material, and an electron transport material. The second doped region includes the host material, the doped material, and an electron transport material.
