Abstract

An organic light-emitting device includes a first electrode, a second electrode facing the first electrode, and an organic layer between the first electrode and the second electrode, the organic layer including an emission layer. The organic layer includes a first compound represented by one of Formulae 1-1 to 1-3 below and a second compound represented by Formula 2 below:

where A 1 to A 5 , B 1 to B 5 , D 1 to D 5 , R 1 to R 5 , R 12 , R 13 , R 41 to R 44 , L 11 , L 2 , L 3 , and ba to bi are as defined in the specification.
