Abstract: A display apparatus includes: a display element including a pixel electrode on a substrate; a bus line spaced from the pixel electrode, and located at the same layer as that of the pixel electrode; a pixel-defining layer defining an emission area of the display element, the pixel-defining layer including: an opening overlapping with the pixel electrode, and exposing at least a portion of the pixel electrode; and a hole exposing a portion of the bus line adjacent to the pixel electrode; a separator on the pixel-defining layer; an intermediate layer on the pixel electrode; and an opposite electrode on the intermediate layer. In a plan view, the separator surrounds the pixel electrode and the hole together. The bus line includes: a first line layer; and a second line layer on the first line layer, and including a tip protruding more than an edge of the first line layer.
