A display device with high display quality is provided. The display device includes a first light-emitting device, a second light-emitting device, and an insulating layer. The first light-emitting device includes a first pixel electrode, a first EL layer, and a common electrode. The second light-emitting device includes a second pixel electrode, a second EL layer, and the common electrode. The insulating layer includes an opening, and includes a first surface in contact with a side surface of the first pixel electrode, a second surface facing the first surface, and a third surface in contact with a bottom surface of the first EL layer. The insulating layer includes a region where the third surface and the top surface of the first pixel electrode are level or substantially level with each other. In a cross-sectional view, an angle formed between the second surface and the third surface is greater than or equal to 80° and less than or equal to 110°. The first EL layer contains the same material as the second EL layer. The first EL layer is separated from the second EL layer.
