Electro-optical device having a holding capacitor comprising a first electrode, a second electrode, and a third electrode with a first capacitor insulation film and a second capacitor insulation film each being formed of first and second capacitor insulation layers

An electro-optical device comprising:

• a pixel electrode provided on a substrate;
• a transistor provided corresponding to the pixel electrode, the transistor being provided between the substrate and the pixel electrode;
• and
• a holding capacitor provided between the pixel electrode and the transistor, the holding capacitor including:
• a first electrode;
• a second electrode provided opposing the first electrode via a first capacitor insulation film, the first capacitor insulation film having:
• a first capacitor insulation layer provided between the first electrode and the second electrode;
• and
• a second capacitor insulation layer provided between the first capacitor insulation layer and the second electrode, the second capacitor insulation layer being made from a material different from a material of the first capacitor insulation layer;
• and
• a third electrode provided opposing the first electrode via a second capacitor insulation film, the second capacitor insulation film having:
• a third capacitor insulation layer provided between the first electrode and the third electrode, the third capacitor insulation layer being made from a same material as a material of the first capacitor insulation layer;
• and
• a fourth capacitor insulation layer provided between the third capacitor insulation layer and the third electrode, the fourth capacitor insulation layer being made from a same material as a material of the second capacitor insulation layer.
