Abstract: A display device includes a substrate including a display part having a first width in a first direction and a pad part protruding from the display part in a second direction crossing the first direction and having a second width in the first direction, the second width being smaller than the first width, and a printed circuit board having a concave-convex shape towards the substrate. As the printed circuit board has the concave-convex shape, a dead space of the display device is reduced.
