Light-emitting device and lighting device

A light-emitting device comprising:

• a substrate;
• a first wiring over the substrate;
• an insulating film over the first wiring;
• a second wiring over the insulating film;
• and
• a first light-emitting element, a second light-emitting element, and a third light-emitting element over the insulating film, each of the first to third light-emitting elements comprising:
• a first electrode;
• a layer containing an organic compound on the first electrode;
• and
• a second electrode on the layer containing an organic compound,
• wherein the layers containing an organic compound of the first and second light-emitting elements are separated from each other by a separation layer,
• wherein the second electrodes of the first and second light-emitting elements are separated from each other by the separation layer,
• wherein the first electrode of the first light-emitting element is directly in contact with the first wiring,
• wherein the second electrode of the first light-emitting element extends beyond an edge portion of the layer containing an organic compound of the first light-emitting element and is directly in contact with the first electrode of the second light-emitting element,
• wherein the second electrode of the third light-emitting element extends beyond an edge portion of the layer containing an organic compound of the third light-emitting element and is directly in contact with the second wiring, and
• wherein the first light-emitting element, the second light-emitting element, and the third light-emitting element are electrically connected to each other in series.
