Electro-optic device and electronic instrument

An electronic instrument, comprising:

• an electro-optic device that includes:
• a substrate;
• a scanning line above the substrate;
• a data line above the substrate;
• a thin film transistor disposed in correspondence with an intersection of the scanning line and the data line;
• a pixel electrode disposed in correspondence with the thin film transistor;
• a pixel potential side capacitance electrode that is electrically connected to the pixel electrode and constitutes a storage capacitor;
• a dielectric film;
• and
• a capacitance line that contains a fixed potential side capacitance electrode that is oppositely disposed via the dielectric film to the pixel potential side capacitance electrode and constitutes the storage capacitor;
• the capacitance line including a body line portion that extends along the scanning line and a portion that extends along the data line;
• and
• a width of a portion that extends along the data line in the capacitance line being formed at least as wide as the data line.
