Claim 3:
4. A manufacturing method for a display substrate, wherein the display substrate is according to claim 1, and the manufacturing method comprises:
forming an active layer and a gate insulating layer successively stacked on a substrate base;
forming a first metal film layer on the gate insulating layer, and forming a pattern of a gate and of a gate line by patterning the first metal film layer;
forming an oxide metal layer on a surface of an opposite region, opposite to a data line to be formed, of the gate line; and
forming an interlayer insulating layer, a second metal film layer and a passivation layer successively on the oxide metal layer, wherein the second metal film layer comprises a pattern of the data line and of a source/drain.
