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

摘要

An electro-optical device includes: a pixel electrode provided on a substrate; a transistor being provided between the substrate and the pixel electrodes; and a holding capacitor, provided between the pixel electrode and the transistor, configured of a first electrode, a second electrode provided opposing the first electrode via a first capacitor insulation film, and a third electrode provided opposing the first electrode via a second capacitor insulation film. Both the first capacitor insulation film and the second capacitor insulation film have multiple layers; the first capacitor insulation film and the second electrode are formed symmetrical to the second capacitor insulation film and the third electrode when viewed from the first electrode.
