Abstract:
1. An electro-optical device including a pixel array area in which are arranged a plurality of pixels, the electro-optical device comprising: a data line and a scanning line extending to intersect each other on a substrate; a pixel-switching thin film transistor disposed in the pixel that corresponds to an intersection of the data line and the scanning line, the pixel-switching thin film transistor being disposed below the data line on the substrate; a storage capacitor, in plan view, being disposed above the data line and having a stacked structure of a fixed-potential electrode, a dielectric layer, and a pixel-potential electrode, the fixed-potential electrode and the pixel-potential electrode being separate layers that sandwich the dielectric layer, and the storage capacitor being disposed in an area including a region opposed to a channel region of the pixel-switching thin film transistor; a pixel electrode electrically connected to the pixel-potential electrode and the pixel-switching thin film transistor, the pixel electrode being disposed above the storage capacitor; a peripheral circuit for driving the pixel electrode through the data line and the scanning line, the peripheral circuit being disposed in a peripheral area located around the pixel array area, the peripheral circuit including a peripheral-circuit thin film transistor having a channel region; and the dielectric layer including a peripheral dielectric layer area having, in plan view, a region opposed to the channel region of the peripheral-circuit thin film transistor.
