Beschreibung
Zusammenfassung:	An organic light-emitting device may include: an anode; a cathode; an organic layer between the anode and the cathode and including an emission layer; and a first exciton quenching layer between the anode and the emission layer and in direct contact with the emission layer. The emission layer may include a host and a dopant, the first exciton quenching layer may include a first quenching material, and the host, the dopant, and the first quenching material may each satisfy Equations 1-1 and 1-2:T1(Q1)≤T1(H) Equation 1-1T1(Q1)≤T1(D) Equation 1-2wherein, in Equations 1-1 and 1-2, T1(Q1) indicates a lowest excited triplet energy level of the first quenching material, T1(H) indicates a lowest excited triplet energy level of the host, and T1(D) indicates a lowest excited triplet energy level of the dopant.
