Patent ID: 7277150

Claim:
An electro-optical device, comprising: a connection terminal unit, including: a first insulating film formed over a substrate and planarized; a first conductive film formed over the first insulating film and that transmits at least a signal from an external circuit; a second insulating film formed over the first insulating film and planarized; and an opening formed in an area of the second insulating film that corresponds to the first conductive film and that extends to the first conductive film; a switching element disposed in an image display area; a data line electrically coupled to the switching element; a pixel electrode electrically coupled to the switching element; a storage capacitor including a pixel-potential-side capacitor electrode electrically coupled to pixel potential of the pixel electrode, and a fixed-potential-side capacitor electrode opposed to the pixel-potential-side capacitor electrode through an insulating film; and a capacitance line formed above the data line and electrically coupled to the fixed-potential-side capacitor electrode, the capacitance line being formed over the first insulating film, and the first conductive film being formed of the same film as that of the capacitance line.
