PROBLEM TO BE SOLVED: To further reduce the size of a display device by using each pad electrode for dual use as an inspection pad electrode. SOLUTION: At least one substrate includes the plurality of pad electrodes at an edge part of at least one side. Each pad electrode of the plurality of pad electrodes includes a metal layer formed on the at least one substrate and a transparent conductive film formed on the metal layer. A flexible wiring board includes a connection electrode mechanically and electrically connected to the transparent conductive film of each pad electrode. Each pad electrode includes a metal layer elimination area in a shape of a recessed part or an opening part in plan view with no metal layer formed thereon in the surface on which the metal layer is formed. The transparent conductive film covers both the area with the metal layer formed thereon and the metal layer elimination area, and is electrically connected to the metal layer in the area with the metal layer formed thereon. The connection electrode of the flexible wiring board overlaps with both the metal layer of the pad electrode and the metal layer elimination area. COPYRIGHT: (C)2009,JPO&INPIT
