Abstract
A high-resolution display device is provided. A display device with both high display quality and high resolution is provided. The display device includes a first light-emitting element and a second light-emitting element. 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. An insulating layer is included between the first pixel electrode and the second pixel electrode. The insulating layer includes a first region overlapping with the first EL layer, a second region overlapping with the second EL layer, and a third region positioned between the first region and the second region. A side surface of the first EL layer and a side surface of the second EL layer are positioned over the insulating layer and are provided to face each other. The common electrode is provided along the side surface of the first EL layer, the side surface of the second EL layer, and a top surface of the insulating layer. A width of the insulating layer is greater than or equal to 2 times and less than or equal to 4 times that of a distance between the first pixel electrode and the second pixel electrode.
