An electrooptical element used in liquid crystal display accordance to this invention is provided with a storage capacitance wiring group and collective drawing wiring. At the time of wet etching of transparent conductor film of pixel electrodes, all wiring of the storage capacitance wiring group are electrically separated each other, and after wet etching of the pixel electrodes, all of the storage capacitance wiring group are electrically connected with collective drawing wiring. The capacitance value of the storage capacitance wiring is small at the time of wet etching of the pixel electrodes, thus preventing the corrosion of the storage capacitance wiring.
