Abstract: According to one embodiment, a motherboard includes inspection pads for adjacent short-circuiting inspection. The motherboard includes a first high-resistance wiring line connecting the inspection pads to each other, a first cut line set to cut out a plurality of display devices from the motherboard, and a second cut line set along an outline shape of each single display device. The inspection pads are each located between the first cut line and the second cut line. The first high-resistance wiring line is disposed across the first cut line and cut along the first cut line before the inspection using the inspection pads. The inspection pads are not connected to each other by the first high-resistance wiring line at the time of the inspection.
