1. An organic light-emitting device, comprising:
a first electrode;
a hole control layer on the first electrode;
an emission layer on the hole control layer;
an electron control layer on the emission layer;
a second electrode on the electron control layer; and
a capping layer on the second electrode,
wherein the emission layer comprises a first sub-emission layer, a second sub-emission layer, and a third sub-emission layer,
the first sub-emission layer comprises a first hole-transporting host, a first electron-transporting host, and a red light-emitting dopant,
the second sub-emission layer comprises a second hole-transporting host, a second electron-transporting host, and a green light-emitting dopant,
the third sub-emission layer comprises a third hole-transporting host, a third electron-transporting host, and a blue light-emitting dopant,
the red light-emitting dopant and green light-emitting dopant emit phosphorescent light, and
the blue light-emitting dopant emits thermally activated delayed fluorescence (TADF) light.
