    Abstract: A display substrate and a method for manufacturing a display substrate are disclosed. In the method, a gate electrode is formed on a base substrate. An active pattern is formed using an oxide semiconductor. The active pattern partially overlaps the gate electrode. A first insulation layer pattern and a second insulation layer pattern are sequentially formed on the active pattern. The first insulation layer pattern and the second insulation layer pattern overlap the gate electrode. A third insulation layer is formed to cover the active pattern, the first insulation layer pattern and the second insulation layer pattern. Either the first insulation layer pattern or the second insulation layer pattern includes aluminum oxide. Forming the first insulation layer pattern and the second insulation layer pattern includes performing a backside exposure process using the gate electrode as an exposure mask.
