Original Abstract Submitted
A display device with high display quality is provided. The display device includes a first organic insulating layer, a first inorganic insulating layer and a second inorganic insulating layer over the first organic insulating layer, a first light-emitting element, a second light-emitting element, and a second organic insulating layer. The first light-emitting element includes a first pixel electrode over the first inorganic insulating layer, a first EL layer over the first pixel electrode, and a common electrode over the first EL layer. The second light-emitting element includes a second pixel electrode over the second inorganic insulating layer, a second EL layer over the second pixel electrode, and the common electrode over the second EL layer. The second organic insulating layer is provided between the first EL layer and the second EL layer, and the common electrode is provided over the second organic insulating layer. The first organic insulating layer includes a depressed portion in a region overlapping with the second organic insulating layer, the first inorganic insulating layer includes a first projecting portion overlapping with the depressed portion, and the second inorganic insulating layer includes a second projecting portion overlapping with the depressed portion.
