20 Claims

1. An organic light-emitting device comprising:

a first electrode;

a second electrode facing the first electrode;

m light-emitting units stacked between the first electrode and the second electrode and comprising at least one emission layer; and

m−1 charge generating layers, each located between two neighboring light-emitting units of them light-emitting units and comprising an n-type charge generating layer and a p-type charge generation layer,

wherein m is an integer of 2 or more,

at least one of the m−1 p-type charge generation layers comprises a first doping layer and a second doping layer,

the first doping layer comprises a first organic material and a first inorganic material,

the second doping layer comprises a second organic material and a second inorganic material, and

the first inorganic material and the second inorganic material are different from each other.
