Abstract

A display device capable of high-quality images can be provided. The display device includes a first light-emitting element, a second light-emitting element, and a gap. The first light-emitting element includes a first light-emitting layer and a first electron-injection layer over the first light-emitting layer, and the second light-emitting element includes a second light-emitting layer and a second electron-injection layer over the second light-emitting layer. The first light-emitting element is adjacent to the second light-emitting element. The gap is placed between the first electron-injection layer and first light-emitting layer and the second electron-injection layer and second light-emitting layer. The first electron-injection layer comprises a region projecting from the side surface of the first light-emitting layer, and the second electron-injection layer comprises a region projecting from the side surface of the second light-emitting layer.
