Claim 9:
10. A method for manufacturing an array substrate, comprising steps of:
forming a thin film transistor device comprising a gate electrode, a source electrode, and a drain electrode;
forming an interface layer of a nitride-oxide material to cover the source electrode and the drain electrode, wherein the interface layer has a thickness less than a preset value;
forming a first transparent conductive layer on the interface layer;
forming a passivation layer on the interface layer and the first transparent conductive layer;
perforating the interface layer and the passivation layer to form a first via and perforating the passivation layer to form a second via, by using one photomask, wherein the first via is located at a position corresponding to the drain electrode, and the second via is located at a position corresponding to a portion of the first transparent conductive layer; and
forming a second transparent conductive layer on the passivation layer, wherein the second transparent conductive layer comprises a drain electrode connection area and a conductive area, and the drain electrode connection area and the conductive area are electrically disconnected by a slit formed between the drain electrode connection area and the conductive area,
wherein the second transparent conductive layer in the drain electrode connection area is electrically connected to the drain electrode through the first via and is electrically connected to the first transparent conductive layer through the second via.
