Patent ID: 7667681

Claim:
An electro-optical device comprising: a substrate; data lines formed above the substrate and extending in a predetermined direction and scanning lines formed above the substrate and extending in a direction intersecting the data lines; switching elements to which scanning signals are supplied from the scanning lines; pixel electrodes to which image signals are supplied from the data lines via the switching elements; a relay electrode that electrically connects one of the switching elements to one of the pixel electrodes; an image display region defined as a region of the substrate in which the pixel electrodes and the switching elements are formed; a peripheral region defining the periphery of the image display region; a driver disposed in the peripheral region; exterior circuit connection terminals comprising electrodes provided in the peripheral region at a position between the driver and a peripheral edge of the substrate; storage capacitors comprising capacitor electrodes to retain potentials of the pixel electrodes for a predetermined period of time; and a capacitor wire which supplies voltage to the capacitor electrodes, wherein the capacitor wire, the electrodes of the exterior circuit connection terminals and the relay electrode are each formed of a same material and in the same film, and wherein the capacitor wire the electrodes of the exterior circuit connection terminals and the relay electrode each have a plural layered structure including an aluminum-based layer and a layer based on a metal other than aluminum.
