Claim 8:
9. A display device comprising:
a substrate having a display area and a peripheral area outside the display area;
a first transistor located over the display area of the substrate and comprising a first semiconductor layer including polycrystalline silicon and a first gate electrode;
a second transistor located over the display area of the substrate and comprising a second semiconductor layer including an oxide semiconductor and a second gate electrode; and
a plurality of wirings located over the peripheral area of the substrate,
wherein the first gate electrode and the second gate electrode are located at difference levels on the substrate,
wherein the plurality of wirings comprise first wirings and second wirings, the first wirings being arranged on a same layer as the first gate electrode and the second wirings being arranged on a same layer as the second gate electrode,
wherein the display device further comprises a capacitor overlapping the first transistor, the capacitor comprising a first electrode and a second electrode, the first electrode being arranged on a same layer as the first gate electrode, and the second electrode being arranged on and overlapping the first electrode,
wherein the display device further comprises a first insulating layer disposed between the first semiconductor layer and the first gate electrode, a second insulating layer disposed between the first gate electrode and the second electrode, a third insulating layer disposed between the second electrode and the second semiconductor layer, a fourth insulating layer disposed between the second semiconductor layer and the second gate electrode, and a fifth insulating layer disposed on the second gate electrode,
wherein the peripheral area further comprises a pad area and a bending area that is disposed between the display area and the pad area, and
wherein the bending area is an area from which the first insulating layer, the second insulating layer, the third insulating layer, the fourth insulating layer, and the fifth insulating layer are removed, and an organic material layer is located in the bending area.
