An electro-optical device substrate includes, upon a substrate: multiple pixel units; multiple first electrodes, provided in a peripheral region located in the periphery of a pixel region in which the multiple pixel units are arranged, that are configured containing a first conductive material; multiple second electrodes, provided in the peripheral region, that are configured containing a second conductive material that differs from the first conductive material; multiple first lines that are formed in the peripheral region, are configured containing the first conductive material, and that electrically connect first electrodes that are adjacent to each other of the multiple first electrodes; and a second line that is formed in the peripheral region and that electrically connects at least one of the multiple first electrodes and at least one of the multiple second electrodes. The electrical resistance of the second line is higher than the electrical resistance of the multiple first lines.
