The light-emitting parts each include: a first electrode that is light-reflective; a first functional layer disposed above the first electrode; a light-emitting layer disposed above the first functional layer; a second functional layer disposed above the light-emitting layer and including ytterbium; and a second electrode disposed above the second functional layer and being light-transmissive. At least one of the light-emitting layer and the first functional layer is an applied film. With respect to each pixel, at least one of the light-emitting parts differs from any other of the light-emitting parts in terms of light emission color, and the at least one light-emitting part differs from the any other of the light-emitting parts in terms of film thickness of at least one of the light-emitting layer and the first functional layer.
