Abstract
A display substrate includes a gate line extending in a first direction on a base substrate, a data line on the base substrate and extending in a second direction crossing the first direction, a gate insulating layer on the gate line, a thin-film transistor and a pixel electrode. The thin-film transistor includes a gate electrode electrically connected the gate line, an oxide semiconductor pattern, and source and drain electrodes on the oxide semiconductor pattern and spaced apart from each other. The oxide semiconductor pattern includes a first semiconductor pattern including indium oxide and a second semiconductor pattern including indium-free oxide. The pixel electrode is electrically connected the drain electrode.
