The circuit layer includes a plurality of insulating layers, at least one of which has an opening. The light emitting element layer includes a light emitting area overlapping the display area, a valley area overlapping the opening and having a concave shape, and a peak area overlapping the non-display area and being on the circuit layer. The thin film encapsulation layer includes an organic encapsulation layer that covers the light emitting area, the valley area, and at least a portion of the peak area.
