1. A display apparatus comprising:
a first sub-pixel electrode;
a metal bank layer in which a first opening overlapping the first sub-pixel electrode is defined, the metal bank layer including:
a first metal layer; and
a second metal layer on the first metal layer;
an insulating layer between an outer portion of the first sub-pixel electrode and the metal bank layer;
a first intermediate layer overlapping the first sub-pixel electrode through the first opening of the metal bank layer;
a first opposite electrode disposed on the first intermediate layer through the first opening of the metal bank layer; and
a low-reflective layer disposed on the second metal layer of the metal bank layer and having a reflectivity less than a reflectivity of the second metal layer, wherein the low-reflective layer includes a metal oxide and is disposed between an upper surface of the metal bank layer and a first dummy portion including a same material as a material of the first intermediate layer.
