LIGHT-EMITTING DEVICE |
| 摘要 |
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)<0.3 (eV) (Numerical Formula 1) |

1. A light-emitting apparatus comprising:
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 different from the first color light, wherein the organic electroluminescence device comprises: 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 that comprises a host material and a dopant material that emits light comprising the first color light and the second color light, and 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 a numerical formula (Numerical Formula 1) below,
ΔST(D)=EgS(D)−Eg77K(D)<0.3 (eV) (Numerical Formula 1). |
