Abstract: A display device includes a non-light emitting area between first and second light emitting portions; a first light emitting structure including a first display element on the first light emitting portion; a first thin film encapsulation layer on the first light emitting structure; and a second light emitting structure on the first thin film encapsulation layer and including a second display element overlapping the second light emitting portion. The first light emitting structure includes a first pixel defining layer defining a first opening and a bank structure on the first pixel defining layer and including first and second bank layers. The second bank layer includes a tip that protrudes toward the first light emitting portion more than a side surface of the first bank layer. The second display element overlaps the first pixel defining layer and contacts the second bank layer.
