An electro-optical device includes a substrate and the following elements. Pixels are disposed in a pixel area on the substrate. Scanning lines and data lines are disposed in the pixel. An image signal line is disposed in a peripheral area located around the pixel area to supply an image signal. A sampling circuit is disposed in the peripheral area and includes transistors disposed in association with corresponding data lines. Each transistor including a 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 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. A layer is disposed above the semiconductor layer. A light-shielding film is disposed over the layer and at least in part of a gap region between adjacent transistors of the transistors in plan view. The light-shielding film is at least partially overlapping with the semiconductor layers of the adjacent transistors in plan view.
