Abstract:
1. An electro-optical device comprising: first and second substrates that are bonded to each other, the first substrate having an extended portion extended from the second substrate on a first side thereof in plan view; a plurality of pixel units that are arranged in a pixel region on the first substrate and individually have pixel electrodes; a data line driving circuit that is disposed along the first side in a peripheral region around the pixel region so as to supply an image signal to the pixel units; a plurality of external circuit connecting terminals that are arranged along the first side in a region of the peripheral region on the extended portion; an image signal line that is relayed around the data line driving circuit from the plurality of external circuit connecting terminals, the image signal line having a first wiring line portion that extends between the data line driving circuit and the pixel region in a direction following the first side; and a sealant that bonds the first and second substrates to each other in a sealing region around the pixel region, wherein the first wiring line portion is at least partially wired within the sealing region, a counter electrode that is formed on the second substrate to commonly face the pixel electrodes individually provided in the plurality of pixel units and is cut in a region facing the first wiring line portion, a vertical connecting terminal that is provided on the first substrate so as to supply a counter electrode potential to the counter electrode, the counter electrode extending to a region facing the vertical connecting terminal aside the cut portion; and a vertical connecting material that electrically connects the vertical connecting terminal and the extended portion of the counter electrode to each other.
