A display device includes a substrate, a first pixel region including a first light emitting element group over the substrate, a second pixel region including a second light emitting element group over the substrate and adjacent to the first light emitting element group, and a partition wall between the first light emitting element group and the second light emitting element. A height of the partition wall is larger than heights of a plurality of emitting elements included in each of the first light emitting element group and the second light emitting element group.
