Electro-optical device and electronic device

An electro-optical device, comprising:

• a light emitting element configured to emit light according to a current flowing between a pixel electrode and a common electrode;
• a plurality of power-supply wiring lines provided at a side of the pixel electrode and including a power-supply wiring line to which a power source potential is supplied;
• a plurality of data lines provided along a predetermined direction;
• a data-signal outputting circuit configured to output a data signal to one data line of the plurality of data lines;
• and
• a conductive wiring line provided so as to overlap with the data-signal outputting circuit in plan view and configured to be supplied with the power source potential through a plurality of mounting terminals, wherein
• each of the plurality of power-supply wiring lines is provided between the plurality of data lines in plan view and is electrically coupled to the conductive wiring line.
