Abstract:
1. A display device comprising: a substrate; a display region having a pixel switch, a pixel electrode which is connected to the pixel switch and an image signal line, and a transparent common electrode formed over the substrate; a peripheral region having a gate signal line which is connected to the pixel switch, and a predetermined connection line; an insulating layer which is disposed on the gate signal line and the predetermined connection line; a conductive layer which is disposed on the insulating layer, is connected to a predetermined pad, and crosses the gate signal line and the predetermined connection line in the peripheral region; a first semiconductor film which is disposed between the insulating layer and the conductive layer; a second semiconductor film which is disposed between the insulating layer and the conductor layer and is separated from the first semiconductor film; wherein the conductor layer is connected to the gate signal line via a pair of diodes; wherein the gate signal line is arranged in the display region and the peripheral region, the predetermined connection line is arranged in the peripheral region, and the transparent common electrode is arranged in the display region; wherein a length of the predetermined connection line is shorter than a length of the gate signal line; wherein the first semiconductor film overlaps, in plan view, a region where the gate signal line crosses the conductive layer; and wherein the second semiconductor film overlaps, in plan view, a region where the predetermined connection line crosses the conductive layer.
