Patent ID: 7742114

Claim:
An electro-optic device comprising: a substrate; data lines and scanning lines extending so as to cross each other; pixel electrodes each arranged for one of a plurality of pixels defined by crossing of the data lines and the scanning lines in plan view of the substrate; thin film transistors each electrically connected to one of the pixel electrodes; and storage capacitors each electrically connected to one of the pixel electrodes, each of the storage capacitors being arranged above the corresponding thin film transistor so as to overlap at least a channel region of the thin film transistor in plan view of the substrate, each of the storage capacitors including a lower electrode composed of a polysilicon film, and a dielectric film, and an upper electrode composed of a metal film, stacked in this order from the bottom, each of the upper electrodes has a stacked structure composed of a first light-shielding layer of titanium nitride, a conductive layer of aluminum, and a second light-shielding layer of titanium nitride stacked in this order from the bottom.
