A display apparatus includes: an auxiliary line comprising a main sub-layer and an upper layer on the main sub-layer; an insulating layer comprising a first opening having a greater width than the auxiliary line, wherein the first opening overlaps the auxiliary line; a first electrode on the insulating layer; an intermediate layer overlapping the first electrode and comprising an emission layer; an auxiliary layer, at least a portion of which overlaps the auxiliary line; and a second electrode on the auxiliary layer, wherein the upper layer of the auxiliary line comprises a tip protruding, in a lateral direction, from a first point, in which a side surface and an upper surface of the main sub-layer meet each other, and being curved upwards from the first point, and the second electrode contacts the side surface of the main sub-layer through the first opening of the insulating layer.
