Patent ID: 8570452

Claim:
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.
