ABSTRACT:
In an active-matrix substrate, an electro-optical device, and a method for manufacturing an active-matrix substrate, to effectively prevent TFTs and other devices formed on a substrate from being destroyed by static electricity generated in a rubbing process for an alignment film or the like, a pixel section (81) in which each pixel electrode is formed in a matrix, a data-line driving circuit (60), a scanning-line driving circuit (70), and an external-connection terminal (13) are formed in each panel area (20) of a large substrate (200) and an antistatic common wiring (48) is made from a conductive layer, when the active-matrix substrate (2) is manufactured. This common wiring (48) is formed so as to cross over the boundary of adjacent panel areas and collects static electricity generated when the rubbing process is applied to the large substrate (200), and the charges are dispersed. Although TFTs made in the low-temperature process are weak against electrostatic destruction, the common wiring (48) protects the TFTs from electrostatic destruction.
