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 the organic layer including an emission layer. The organic layer includes a first compound represented by Formula 1 and a second compound represented by Formula 2: n nwhere R 1 , to R 3 , R 11 to R 13 , R 21 to R 24 , X, L 1 to L 3 , L 11 to L 13 , a1 to a3, b1 to b3, c1 to c3, a11 to a13, b11 to b13, and c11 to c13 are as defined in the specification. |
