Abstract:
An oxide thin film transistor array substrate, a manufacturing method thereof and a display panel are provided. The oxide TFT array substrate includes a base substrate and an oxide TFT, a gate line, a data line and a pixel electrode provided on the base substrate, the drain electrode of the oxide TFT being connected with the pixel electrode, wherein a connection structure is provided between the source electrode of the oxide TFT and the data line, by which the source electrode of the oxide TFT and the data line are electrically connected, and the resistivity of the connection structure is larger than the resistivity of the source electrode.
