Occurrence of a crosstalk phenomenon in a light-emitting device including a tandem element is suppressed. A light-emitting device includes: lower electrodes over an insulating layer; a partition over a portion between the lower electrodes, which includes an overhang portion over an end portion of each of the lower electrodes; a first light-emitting unit over each of the lower electrodes and the partition; an intermediate layer 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 distance between the overhang portion and each of the lower electrodes is larger than the total thickness of the first light-emitting unit and the intermediate layer over the lower electrode.
