Abstract
According to one embodiment, a display device includes a lower electrode, a second insulating layer including an opening overlapping the lower electrode, an organic layer including a light-emitting layer and a functional layer, disposed in the opening and covering the lower electrode and an upper electrode covering the organic layer. The functional layer includes a first region located between the lower electrode and the light-emitting layer and a second region including an end surface located directly above the second insulating layer. A dopant concentration of a guest material in the second region is lower than the dopant concentration of the guest material in the first region.
