Claim 0:
1. A display device comprising:
a substrate having a display area and a peripheral area outside the display area;
a first transistor including a first gate electrode, a first semiconductor layer, and a first insulating layer disposed between the first gate electrode and the first semiconductor layer;
a capacitor overlapping the first transistor and comprising a first electrode, a second electrode, and a second insulating layer disposed between the first electrode and the second electrode, the first electrode being the first gate electrode and the second electrode overlapping the first electrode;
a third insulating layer disposed on the second electrode;
a second transistor including a second gate electrode, a second semiconductor layer, and a fourth insulating layer disposed between the second gate electrode and the second semiconductor layer, the second gate electrode of the second transistor being disposed over the first gate electrode of the first transistor and the second insulating layer and the third insulating layer being disposed between the first gate electrode and the second semiconductor layer; and
a plurality of wirings located over the peripheral area of the substrate,
wherein the plurality of wirings comprise first wirings and second wirings, the first wirings and the second wirings being located at different levels on the substrate and are alternately arranged with each other, and
wherein the first wirings and the first gate electrode are disposed on the first insulating layer to directly contact an upper surface of the first insulating layer, are disposed at a same level on the substrate, and include a same material, and the second wirings and the second gate electrode are disposed on the fourth insulating layer to directly contact an upper surface of the fourth insulating layer, are disposed at a same level on the substrate, and include a same material.
