Abstract: 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.
