Abstract: A light-emitting apparatus includes an organic electroluminescence device, a first color conversion portion that transmits a first color light, and a second color conversion portion that transmits a second color light. The organic electroluminescence device includes an anode, a cathode, and one or more organic layers interposed between the anode and the cathode. At least one of the organic layer(s) is an emitting layer including a host material and a dopant material that emits light including the first color light and the second color light. A difference ΔST(D) between singlet energy EgS(D) of the dopant material and an energy gap Eg77K(D) at 77K of the dopant material satisfies Numerical Formula 1 below,

ΔST(D)=EgS(D)−Eg77K(D)
