A display device includes a substrate; pad electrodes disposed on the substrate and spaced apart from one another; a driving member including bumps, which overlap the pad electrodes in a thickness direction of the substrate and are spaced apart from one another; conductive members disposed between the pad electrodes and the bumps to electrically connect the pad electrodes and the bumps; and non-conductive members disposed adjacent to the pad electrodes, the bumps, and the conductive members, wherein the conductive members and the non-conductive members include different materials, each of the conductive members includes a first side surface that faces a corresponding one of the non-conductive members, each of the non-conductive members include a second side surface that faces a corresponding one of the conductive members, and a part of the first side surface and a part of the second side surface directly contact one another.
