Abstract: A display device includes a substrate comprising a display part, a pad part, and a bending part between the display part and the pad part, a display layer disposed on a first surface of the display part and comprising pixels, a pad electrode disposed on a first surface of the pad part, and a metal layer disposed on a second surface of the display part and on a second surface of the pad part. The second surface of the display part is opposite to the first surface of the display part, and the second surface of the pad part is opposite to the first surface of the pad part. A thickness of the bending part is smaller than at least one of a thickness of the display part and a thickness of the pad part. A planar shape of the bending part is determined by the metal layer.
