US 2024/0405178 A1 · DISPLAY DEVICE AND METHOD OF FABRICATING THE SAME

Abstract

A display device may include: a substrate having a display area and a non-display area, and including a first surface and a second surface facing away from each other in a thickness direction of the substrate, and a side surface connecting the first and second surfaces; a light emitting element on the first surface of the substrate in the display area; a pad electrode on the first surface of the substrate in the non-display area; an intermediate electrode on the second surface of the substrate in the display area; and a side connection line on the side surface, and electrically connected to each of the pad electrode and the intermediate electrode. The pad electrode may include a first pad electrode and a second pad electrode. Opposite side surfaces of the second pad electrode may have the same inclination angles as opposite side surfaces of the first pad electrode.
