1. An electro-optical device, comprising:

  • a data line and a scanning line that intersect each other;

    a transistor supplied with a scanning signal by the scanning line;

    a pixel electrode supplied, through the transistor, with an image signal from the data line; and

    a holding capacitor including a first electrode electrically connected to the transistor and the pixel electrode, a second electrode disposed opposite to the first electrode, and a multilayer dielectric film structure disposed between the first electrode and the second electrode, the multilayer dielectric film structure includes;

    a low dielectric film; and

    a first high dielectric film and a second high dielectric film sandwiching the low dielectric film from a first electrode side and a second electrode side, respectively, and each with the permittivity relatively higher than permittivity of the low dielectric film.
