Claim 16:
17. A display device comprising:
a base substrate;
a first transistor above the base substrate and comprising a first semiconductor pattern below first, second, and third insulation layers and a first gate between the first insulation layer and the second insulation layer;
a second transistor above the base substrate and comprising a second gate between the first insulation layer and the second insulation layer, a second semiconductor pattern between the second insulation layer and the third insulation layer, and a third gate above the first, second and third insulation layers and electrically connected to the second gate;
a third transistor above the base substrate and comprising a third semiconductor pattern below the first, second, and third insulation layers and a fourth gate between the first insulation layer and the second insulation layer;
a light emitting diode above the third insulation layer,
a conductive pattern on the first gate and overlapping the first gate; and
a conductive connection pattern on the third insulation layer,
wherein the first semiconductor pattern comprises a polysilicon semiconductor and the second semiconductor pattern comprises an oxide semiconductor,
the third insulation layer is disposed between the conductive pattern and the third gate, and
the conductive connection pattern electrically connects one semiconductor pattern of the first, second, and third semiconductor patterns to another semiconductor pattern of the first, second, and third semiconductor patterns.
