Abstract: A display device includes a display substrate and a printed circuit board (PCB). The display substrate includes a display area to display an image, and includes a pad area outside the display area. The PCB is bonded to a surface of the display substrate in the pad area. The PCB includes a base film, first terminal wires positioned at the base film, second terminal wires positioned at the base film, first sub-pad terminals electrically connected to the first terminal wires through contact holes formed in the base film, and second sub-pad terminals directly and electrically connected to the second terminal wires without contact holes. The first sub-pad terminals and the second sub-pad terminals are alternately arranged. The first terminal wires and the second terminal wires are, in a view normal to the surface, spaced apart from one another.
