Patent ID: 7116390

Claim:
An electro-optical device, comprising: a plurality of pixel portions provided in an image display region on an element substrate; in a peripheral region of the image display region on the element substrate, a plurality of external circuit connection terminals, a plurality of main wiring lines each having one end coupled to each of the plurality of external circuit connection terminals, and peripheral driving circuits coupled to the other ends of the main wiring lines, the peripheral driving circuits driving the pixel portions based on electric signals supplied from the external circuit connection terminals through the main wiring lines, a counter electrode provided in the peripheral region on a counter substrate that is arranged to face the element substrate; a counter electrode potential line that supplies counter electrode potential to the counter electrode, which is at least one of the plurality of main wiring lines, upper and lower conduction terminals that are provided in the peripheral region on the element substrate, and that are connected to the counter electrode potential line, the plurality of main wiring lines being made of a same conductive film and being planarly laid out so as not to intersect each other in the peripheral region; and the counter electrode potential line being closest to edges of the element substrate, among the plurality of main wiring lines.
