Abstract

An electronic apparatus includes an organic light-emitting device including: a first electrode, a second electrode facing the first electrode, m light-emitting units stacked between the first electrode and the second electrode and including at least one emission layer; and m−1 charge generating layers, each located between two neighboring light-emitting units of the m light-emitting units and including 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 includes a first doping layer and a second doping layer, the first doping layer includes a first organic material and a first inorganic material, the second doping layer includes a second organic material and a second inorganic material, and the first inorganic material and the second inorganic material are different from each other.
