Occurrence of a crosstalk phenomenon in a light-emitting device is inhibited. A light-emitting device including an insulating layer 416; a first lower electrode 421a formed over the insulating layer; a second lower electrode 421b formed over the insulating layer; a partition 418 formed over the insulating layer and positioned between the first lower electrode and the second lower electrode; a stacked-layer film 423 which is formed over the first lower electrode, the partition, and the second lower electrode and includes a light-emitting layer containing a light-emitting substance and a layer having higher conductivity than that of the light-emitting layer; an upper electrode 422 formed over the stacked-layer film; and a shield electrode 419 which is formed under the partition and does not overlap with the first lower electrode and the second lower electrode.
