ABSTRACT:
An electro-optical apparatus is provided with a pixel electrode, a TFT connected thereto, and a scanning line and a data line connected thereto above a TFT array substrate. Furthermore, a junction layer, which performs the function of a pixel-potential-side capacitor electrode of a storage capacitor, and a capacitor line including a fixed-potential-side capacitor electrode arranged to face this with a dielectric film therebetween, are provided. A multilayer junction-layer connecting the junction layer and the pixel electrode is provided from the same multilayer film as the data line, while covering a notch portion of the capacitor line. The upper film of this multilayer film is made of a material unlikely to be subject to electrolytic corrosion by ITO of the pixel electrode compared with that in the lower film.
