Patent ID: 7215388

Claim:
An electro-optical device, comprising: a substrate; a data line extending above the substrate; a scanning line extending in a direction intersecting the data line; a thin film transistor including a semiconductor layer and a gate electrode, the gate electrode being supplied with scanning signals by the scanning line; a pixel electrode supplied with image signals by the data line through the thin film transistor; an interlayer insulating film arranged beneath the pixel electrode; a passivation film arranged directly beneath the pixel electrode with no additional layer between the passivation film and the pixel electrode and directly on a surface of the interlayer insulating film with no additional layer between the passivation film-and the interlayer insulating film, the passivation film including at least one of boron or phosphorus; and a storage capacitor electrically connected to the thin film transistor and to the pixel electrode, and a capacitor wiring line to supply fixed electric potential to the storage capacitor; wherein: the interlayer insulating film includes a second interlayer insulating film on which the capacitor wiring line is laminated, under a first interlayer insulating film, and a third interlayer insulating film on which the data line is laminated, under the second interlayer insulating film, and a second passivation film including at least one of boron or phosphorus is arranged on a surface of the second interlayer insulating film or a surface of the third interlayer insulating film.
