Abstract:
An electrooptical element comprising:an electrooptical material interposed between a pair of substrates arranged in an opposing manner; wherein one of the substrates comprises thereon a gate wiring and storage capacitance wiring group including a plurality of wiring formed on a same layer as the gate wiring and formed of single-layered Al or Al alloy; a gate insulating layer formed on the substrate so as to cover the gate wiring and the storage capacitance wiring group; wherein during formation of the storage capacitance wiring group, all of the plurality of wiring in the storage capacitance wiring group are electrically and physically separated from each other such that the plurality of wiring have a substantially non-corroded surface after etching of a transparent conductive layer formed on the gate insulating layer; TFTs formed on the gate insulating layer; pixel electrodes electrically connected to the TFTs; source wiring intersecting with the gate wiring and provided on the substrate via the gate insulating layer; and collective drawing wiring formed on the gate insulating layer for mutually connecting said all of the plurality of wiring in the storage capacitance wiring group in an electrical manner through contact holes provided on the gate insulating layer.
