Abstract
Occurrence of a crosstalk phenomenon is prevented in a light-emitting device including a tandem element. The light-emitting device includes an insulating layer, a first lower electrode over the insulating layer, a second lower electrode over the insulating layer, a partition positioned over the insulating layer and between the first lower electrode and the second lower electrode, a first light-emitting unit over the first lower electrode, the partition, and the second lower electrode, intermediate layers over the first light-emitting unit, a second light-emitting unit over the intermediate layer, and an upper electrode over the second light-emitting unit. The partition has a first depression.
