Abstract: A display device includes a substrate having a top surface, a bottom surface, and a first contact hole passing through the top surface and the bottom surface; a thin film transistor disposed above the top surface and including a semiconductor layer; a display element connected to the thin film transistor; a top conductive pattern disposed between the substrate and the thin film transistor and overlapping the semiconductor layer of the thin film transistor; a bottom conductive pattern disposed on the bottom surface and connected to the top conductive pattern through the first contact hole; and a bottom planarization layer disposed on the bottom surface, the bottom planarization layer disposed on the bottom conductive pattern.

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.

Abstract: A display panel including a penetration portion includes: a substrate including a central area and an outer area extending from an outer side of the central area, the central area including a first central area and a second central area spaced apart from the first central area by the penetration portion therebetween; and a display element arranged on the substrate and including a first display element and a second display element, the first display element overlapping at least a portion of the first central area, and the second display element overlapping at least a portion of the second central area. At least one of an edge of the central area and an edge of the outer area defines at least a portion of the penetration portion, and a thickness of the substrate in the outer area is less than a thickness of the substrate in the central area.
