Claim Text:
1. A display device comprising: a transparent substrate; a display region in which a plurality of scanning signal lines and a plurality of video signal lines intersecting the plurality of scanning signal lines are formed on the transparent substrate; and a first conductive layer on the transparent substrate, a second conductive layer on the first conductive layer, and a third conductive layer on the second conductive layer, wherein a first terminal is formed outside the display region on the transparent substrate and connects to a first terminal wiring and a second terminal wiring electrically connecting to a semiconductor chip; wherein the first terminal comprises the first conductive layer, the second conductive layer, the third conductive layer having an exposed planar terminal on the second conductive layer, a plurality of first vias each of which is connected between the first conductive layer and the second conductive layer, and a plurality of second vias each of which is connected between the second conductive layer and the third conductive layer, wherein the first conductive layer has a first region overlapped with the third conductive layer and a second region not overlapped with the third conductive layer, wherein the first conductive layer has a slit between the first region and the second region in plan view, wherein the second region connects to the first terminal wiring and the second terminal wiring, and wherein each of the plurality of first vias is not overlapped with each of the plurality of second vias in plan view.
