Abstract: A display apparatus includes: a substrate including a first surface, a second surface opposite the first surface, a display area defined on the first surface, and a non-display area defined on the second surface; a plurality of display elements at the display area on the first surface of the substrate; a driving circuit on the second surface and overlapping with the display area of the substrate; a first conductive pattern on the second surface of the substrate; and a second conductive pattern on the first surface of the substrate and connected to the first conductive pattern via a contact hole extending through the substrate. A surface roughness of the second surface of the substrate is greater than a surface roughness of the first surface of the substrate.
