Abstract
A display apparatus includes: a base substrate; a thin film transistor and a power supply wire on the base substrate; a first electrode on the base substrate, and electrically connected to the thin film transistor; a light emitting layer and a common layer on the first electrode; and a second electrode on the common layer. The power supply wire includes: a first conductive layer; a second conductive layer on the first conductive layer; and a third conductive layer on the second conductive layer. The third conductive layer protrudes more than the second conductive layer on a side surface of the power supply wire, and the second electrode contacts a side surface of the second conductive layer.
