A display apparatus includes a substrate and pad terminals arranged on the substrate in a first direction in a pad area and including a first pad terminal disposed at outer side and an ith pad terminal disposed at inner side. Each of the pad terminals includes a lower conductive layer, convex portions, and an upper conductive layer. An overlapping area between the lower conductive layer of the first pad terminal and the convex portions is different from an overlapping area between the lower conductive layer of the ith pad terminal and the convex portions in a plan view.
