Abstract: The present invention relates to an improved method of manufacturing pads of a display panel. Al or Al alloy is deposited and patterned on a glass substrate for forming a plurality of gate electrodes and lines. Then a plurality of pads are formed with Ta or Ti, which is capable of forming an anodic oxide thereof; each pad extending over an edge of each of the respective gate lines to provide an electrical coupling therebetween. Thereafter, the entire surface of the pads, gate electrodes and lines is subjected to an anodic oxidation under a high anodization voltage. Anodic oxide layers on the pads are then etched away together with a silicon nitride layer during a subsequent pad opening processing step. Consequently, in accordance with the invention, a photoresist masking process for the selective anodic oxidation of Al gate lines and electrodes is eliminated.
