Mounting structure mounting substrate, electro-optical device, and electronic apparatus

A mounting structure comprising:

• a first substrate that has a first surface and a second surface;
• a plurality of first connection terminals that are disposed on the first surface in a first direction;
• a plurality of second connection terminals that are disposed on the first surface in a second direction perpendicular to the first direction and that are separated from the first connection terminals by a gap;
• a plurality of connection wiring lines that are disposed on the second surface, each having first portions that substantially overlap the first and second connection terminals in plan view and are formed smaller than the first and second connection terminals in plan view, and a second portion that has a width in the first direction narrower than widths of the first portions in the first direction;
• a plurality of through holes that pass through the first substrate to connect the second connection terminals to corresponding connection wiring lines;
• and
• a second substrate that has a plurality of third connection terminals, the third connection terminals being connected to the first and second connection terminals and correspondingly overlapping the first and second connection terminals in plan view.
