Abstract:
1. A method for fabricating an active matrix array structure, the method comprising: forming a first conductive layer on a substrate; performing a first photomasking process to pattern the first conductive layer into a first patterned conductive layer, and the first patterned conductive layer further comprises a plurality of scan lines, a plurality of gates and a plurality of scan contact pads, and the scan lines are connected with the gates and the scan contact pads; forming sequentially a gate insulating layer, a semiconductor layer and a second conductive layer on the substrate; performing a second photomasking process to form a patterned semiconductor layer and a second patterned conductive layer above the patterned semiconductor layer, and the second patterned conductive layer includes a plurality of data lines, a plurality of source electrodes, a plurality of drain electrodes and a plurality of data contact pads, and the data lines respectively intersect with the scan lines, and the data lines connect with the source electrodes and the data contact pads, and the drain electrodes and the source electrodes are respectively configured above the gates; forming an overcoat material layer on the substrate; performing a third photomasking process to form a patterned gate insulating layer and a patterned overcoat layer, and the patterned gate insulating layer comprises a plurality of first openings, and the patterned overcoat layer comprises a plurality of second openings, and the second openings which are configured above the first openings and expose a portion of the first patterned conductive layer exposed by the first openings, and a portion of the second openings exposes a portion of the second patterned conductive layer; and forming a transparent conductive layer globally on the substrate, wherein a portion of the transparent conductive layer disposed in the first openings and the second openings is broken off at a position that is in between the substrate and the patterned overcoat layer.
