Abstract:
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 electrically connected to a capacitor wiring, and a multilayer dielectric film structure including: wherein the holding capacitor is disposed above a semiconductor layer of the transistor; and wherein stack-layer positions of the first high dielectric film and the second high dielectric film in the direction toward the first electrode and the second electrode, respectively, are symmetrical with respect to the low dielectric film; and wherein the multilayer structure is formed by stacking silicon nitride films of the same number on both sides of the high temperature oxide film.
