The display substrate may include a substrate, a first lower gate electrode, an insulation pattern, a first insulation layer, and a first active pattern. The first lower gate electrode may be disposed on the substrate. The insulation pattern may be disposed on and patterned to correspond to the first lower gate electrode and may include a silicon nitride. The first insulation layer may be disposed on the insulation pattern and may include a silicon oxide. The first active pattern may be on the first insulation layer and formed of oxide semiconductor and may include a first channel region overlapping the first lower gate electrode and a first wiring region disposed on a side of the first channel region.
