Claim 11:
12. An organic light-emitting display apparatus, comprising:
a timing controller;
a scan driver;
a source driver; and
an organic light-emitting display panel including an organic light-emitting device,
wherein the organic light-emitting device comprises:
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; and
a second electrode on the electron control layer,
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 phosphorescent light and thermally activated delayed fluorescence (TADF) light.
