Abstract: A highly reliable display device is provided. The display device includes a first light-emitting element, a second light-emitting element adjacent to the first light-emitting element, a first insulating layer provided between the first light-emitting element and the second light-emitting element, a light-blocking layer over the first insulating layer, and a second insulating layer over the light-blocking layer. The first light-emitting element includes a first pixel electrode, a first EL layer over the first pixel electrode, and a common electrode over the first EL layer; and the second light-emitting element includes a second pixel electrode, a second EL layer over the second pixel electrode, and the common electrode over the second EL layer. The common electrode is placed over the second insulating layer.
