Abstract
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.
