An electro-optic device includes 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 is 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. The
storage capacitors each include a lower electrode composed of a
polysilicon film and an upper electrode composed of a dielectric film and
a metal film stacked in this order from the bottom.
