Abstract

A display device includes a light emitting element layer including a first light emitting element on a first pixel electrode of the first substrate, a first dummy element layer spaced apart from the first light emitting element, the first dummy element layer and the first light emitting element including a same material, a second light emitting element on the first dummy element layer and on a second pixel electrode of the first substrate, a first metal pattern on the first pixel electrode and electrically connected to the first pixel electrode and the first light emitting element, a second metal pattern on the second pixel electrode and electrically connected to the second pixel electrode and the second light emitting element, and a common electrode on the first light emitting element and the second light emitting element. The second metal pattern is in a through hole penetrating the first dummy element layer.
