Abstract

A display device with high display quality and high reliability is provided. The display device includes a first light-emitting element, a second light-emitting element positioned to be adjacent to the first light-emitting element, a first protective layer, a second protective layer, and an insulating layer. The first light-emitting element includes a first pixel electrode, a first EL layer, and a common electrode. The second light-emitting element includes a second pixel electrode, a second EL layer, and the common electrode. The first EL layer is provided over the first pixel electrode, and the second EL layer is provided over the second pixel electrode. The first protective layer includes a region overlapping with a side surface of the first pixel electrode, a side surface of the second pixel electrode, a side surface of the first EL layer, and a side surface of the second EL layer. The insulating layer is provided over the first protective layer, and the second protective layer is provided over the insulating layer. The common electrode is provided over the first EL layer, over the second EL layer, and over the second protective layer.
