Abstract:
1. An electro-optical device comprising: a substrate; a plurality of pixels disposed in a pixel area on the substrate; a plurality of scanning lines and a plurality of data lines disposed in the pixel area; an image signal line disposed in a peripheral area located around the pixel area to supply an image signal; a sampling circuit disposed in the peripheral area and including a plurality of transistors disposed in association with corresponding data lines, each transistor including a semiconductor layer formed directly on an underlayer insulating film, each semiconductor layer having (i) a source region connected to a source wiring which is electrically connected to the image signal line and which is disposed in a first direction in which the plurality of data lines are extended, (ii) a drain region connected to a drain wiring which is electrically connected to the corresponding data line and which is disposed in the first direction, and (iii) a channel region formed between the source region and the drain region, each transistor further including a gate electrode which is disposed on a dielectric layer higher than the semiconductor layer and which is overlapped with the channel region; an interlayer insulating film disposed above the semiconductor layer; a light-shielding film disposed over the interlayer insulating film and disposed at least in part of a gap region between adjacent transistors of the plurality of transistors in plan view, the light-shielding film at least partially overlapping with the semiconductor layers of the transistors in plan view, and a shielding wiring formed of the same film as the film forming the gate electrode, the shielding wiring being disposed in the gap region directly on the underlayer insulating film such that at least a portion of the shielding wiring is positioned between adjacent semiconductor layers.
