1. A light-emitting apparatus comprising:
a first light-emitting device and a second light-emitting device,
wherein the first light-emitting device comprises a first pixel electrode, a first optical adjustment layer, a first light-emitting layer, a second light-emitting layer, and a common electrode,
wherein the second light-emitting device comprises a second pixel electrode, a second optical adjustment layer, the first light-emitting layer, the second light-emitting layer, and the common electrode,
wherein the first optical adjustment layer is positioned between the first pixel electrode and the common electrode,
wherein the second optical adjustment layer is positioned between the second pixel electrode and the common electrode,
wherein the first optical adjustment layer and the second optical adjustment layer are separately provided,
wherein the first light-emitting layer and the second light-emitting layer each comprise a region positioned between the first pixel electrode and the common electrode and a region positioned between the second pixel electrode and the common electrode,
wherein the first light-emitting device emits infrared light emitted by the first light-emitting layer, and
wherein the second light-emitting device emits visible light emitted by the second light-emitting layer.
