1. A manufacturing method of a thin film transistor array substrate, comprising:

  • forming a first passivation layer on a substrate formed with a gate scan line, a thin film transistor, a data line, a first display electrode and a board wiring PAD region, and forming a board wiring PAD-region via hole in the first passivation layer above the board wiring PAD region through a first patterning process;

    forming a second passivation layer on the substrate formed with the board wiring PAD-region via hole, and forming a pixel-region via hole in the first passivation layer and the second passivation layer above the first display electrode through a second patterning process in such a way that the pixel-region via hole has a top-size smaller than its bottom-size; and

    applying a transparent conductive layer on the substrate formed with the pixel-region via hole to form a second display electrode.
