Abstract:
1. A manufacturing method of a thin film transistor array substrate, comprising: providing a substrate having a display region and a sensing region, wherein at least a display thin film transistor is formed in the display region, a first sensing electrode is formed in the sensing region, and an inter-layer dielectric layer is disposed on the substrate, covers the display thin film transistor, and exposes the first sensing electrode; forming a patterned photo sensitive dielectric layer on the first sensing electrode; and forming a patterned transparent conductive layer on the substrate, wherein the patterned transparent conductive layer comprises a pixel electrode and a second sensing electrode, the pixel electrode is coupled to the corresponding display thin film transistor, and the second sensing electrode is located on the patterned photo sensitive dielectric layer.
