Abstract: A display device includes a first pixel, a second pixel, and a third pixel each of which includes a first electrode on a substrate, a first sub-light emitting portion on the first electrode, a first charge generation layer on the first sub-light emitting portion, a second sub-light emitting portion on the first charge generation layer, and a second electrode on the second sub-light emitting portion. The second sub-light emitting portion includes a hole transport layer on the first charge generation layer and an emission layer on the hole transport layer. The hole transport layer of the first pixel is on the first charge generation layer of the first pixel and completely covers the first charge generation layer of the first pixel. A part of an edge of the hole transport layer of the first pixel overlaps the first charge generation layer of the second pixel.
