Abstract
A thin film transistor (TFT) array substrate, a manufacturing method thereof and a display device are provided. The manufacturing method comprises: forming a first passivation layer () on a substrate (), 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 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.
