    Abstract: Provided is an organic light-emitting device (OLED), comprising
    a first electrode;
    a second electrode;
    an emission layer disposed between the first electrode and the second electrode;
    a hole transport region disposed between the first electrode and the emission layer and comprising a hole transport layer; and
    an electron transport region disposed between the emission layer and the second electrode and comprising an electron transport layer,
    wherein the emission layer comprises an electron-transporting host and a hole-transporting host,
    the hole transport layer comprises a hole transport material,
    the electron transport layer comprises an electron transport material, and
    the OLED satisfies Equations 1 and 2 below:

    0.75eV H(ET) - LUMO H(HT) I ≤ 0.90eV

    I E(S 1 , H(ET) ) - E(S 1 , H(HT) ) I
    wherein in Equations 1 and 2,
    LUMO H(ET) refers to a lowest unoccupied molecular orbital (LUMO) energy level of the electron-transporting host,
    LUMO H(HT) refers to an LUMO energy level of the hole-transporting host,
    E(S 1 , H(ET) ) refers to a singlet energy level of the electron-transporting host, and
    E(S 1 , H(HT) ) refers to a singlet energy level of the hole-transporting host.
