Patent ID: 7728913

Claim:
An electro-optical device comprising a first substrate, a second substrate, and an electro-optical material between the first substrate and the second substrate, the first substrate comprising: a plurality of scanning lines and a plurality of data lines that intersect with each other; a plurality of pixel electrodes that are provided so as to correspond to the intersections of the plurality of scanning lines and the plurality of data lines; a sampling circuit that is disposed in a peripheral region positioned around the region in which the plurality of pixel electrodes are arranged, so as to correspond to the plurality of data lines disposed along an extending direction of a first side of the first substrate; a data line driving circuit that is disposed in the peripheral region and closer to the first side than the sampling circuit so as to supply a driving signal to the sampling circuit; at least one image signal terminal disposed in the peripheral region and closer to the first side than the data line driving circuit, the image signal terminal being supplied with a image signal externally; an image signal line that supplies the image signal to the sampling circuit, the image signal line extending from the image signal terminal, bypassing the data line driving circuit, and reaching the sampling circuit; and a vertical conduction terminal disposed near a second side intersecting with the first side of the first substrate, in the peripheral region, vertical conduction terminal enabling electrical conduction between the first substrate and the second substrate, wherein the image signal line has a first straight line portion extending in a direction of the second side and a second straight line portion extending in the direction of the first side, and an intermediate wiring portion connecting the first straight line portion and the second straight line portion, an angle of a corner formed between each of the first straight line portion and the second straight line portion and the intermediate wiring portion is an obtuse angle, and the intermediate wiring portion is wired to pass around the vertical conduction terminal.
