Abstract: A display apparatus includes a substrate, a first display element, a first bank, a first functional layer, and a dummy unit. The first display element overlaps a face of the substrate. The first functional layer overlaps the first display element, is confined by at least the first bank, and includes a first base resin, first quantum dots, and first scatterers. The dummy unit overlaps no display elements of the display apparatus in a direction perpendicular to the face of the substrate and includes a first wall, a dummy-unit base resin, and dummy-unit scatterers. The dummy-unit base resin and the dummy-unit scatterers are confined by at least the first wall. A concentration of the dummy-unit scatterers in the dummy-unit base resin is greater than a concentration of the first scatterers in the first base resin.
