Abstract:
An organic electroluminescence multicolor light-emitting apparatus including: a substrate; and a first light-emitting device and a second light-emitting device being arranged in parallel relative to the surface of the substrate; wherein the first light-emitting device includes, between an anode and a cathode, a first organic layer, a second organic layer and a third organic layer in this sequence from the anode side in a direction perpendicular to the surface of the substrate, the second light-emitting device includes, between an anode and a cathode, a second organic layer and a third organic layer in this sequence from the anode side in a direction perpendicular to the surface of the substrate, the first organic layer includes a first emitting dopant, the third organic layer includes a second emitting dopant, and the second organic layers independently comprise any one of compounds represented by the following formulas (1) to (6).
