ELECTROOPTICAL APPARATUS, METHOD OF PRODUCING THE SAME AND ELECTRONIC APPARATUS

The invention provides an electrooptical apparatus, such as a liquid crystal apparatus, including a built-in-peripheral circuit in which the resistance of input/output wirings in the peripheral circuit is reduced by effectively using thin films forming pixels, thereby making it possible to display a high-quality image. The liquid crystal apparatus includes a liquid crystal layer disposed between a pair of substrates and pixel electrodes formed in a matrix fashion on a TFT array substrate. A light blocking film made of refractory metal is provided under TFTs of respective pixels, scanning lines, and capacitance lines. There are also provided peripheral wirings, such as image signal lines including second wiring made of the same metal film as that of the data lines and also including first wiring whose layers are conductive film as that of the light blocking film and the same polysilicon film as that of the scanning lines, respectively.
