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