摘要： A display apparatus and a manufacturing method may avoid electrical shorting caused by protrusion structures that result from a difference in etch rates. The display apparatus includes a substrate, a semiconductor layer on the substrate, a first metal layer arranged on the semiconductor layer, insulated from the semiconductor layer, and including a first metal layer having a first etch rate under a predetermined condition, and a second metal layer arranged on the first metal layer, contacting an upper surface of the first metal layer, including a second metal material having a second etch rate under the predetermined condition, the second etch rate being less than the first etch rate, and arranged in the upper surface of the first metal layer when viewed in a direction perpendicular to the substrate.

摘要： 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.
