摘要： A display substrate includes a gate metal pattern including a gate line disposed on a base substrate and a gate electrode electrically connected with the gate line, an active pattern entirely overlapped with the gate metal pattern and comprising an oxide semiconductor and a data metal pattern disposed on the active pattern and including a data line, a source electrode electrically connected with the gate line and a drain electrode spaced apart from the source electrode. The active pattern has an overlapped region in which the active pattern is overlapped with the source electrode and the drain electrode and an exposed region in which the active pattern is not overlapped with the source electrode and the drain electrode. The thickness of the overlapping region and a thickness of the exposing region are same.
