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, disposed in the opening and covering the lower electrode and an upper electrode covering the organic layer. The light-emitting layer includes a first bottom surface, a first end surface and a second end surface intersecting the first end surface. An angle between the first end surface and the first bottom surface in a cross-sectional view along a first direction is greater than an angle between the second end surface and the first bottom surface in a cross-sectional view along a second direction.
