A watch component having an oxide film formed by oxidizing a base material containing iron as a main component, an average film thickness of the oxide film is from 70 nm to 145 nm, and a variation in film thickness of the oxide film is equal to or less than 35%.

Watch component, and watch

An electro-optical device includes a pixel electrode provided on a substrate, a transistor provided between the substrate and the pixel electrode, a first capacitor electrode provided between the pixel electrode and the transistor, and be electrically connected to the pixel electrode and the transistor, a second capacitor electrode provided between the pixel electrode and the first capacitor electrode, be located so as to be opposite the first capacitor electrode via a capacitor insulating film, and be supplied with a predetermined electric potential, and a light-shielding film provided between the pixel electrode and the second capacitor electrode, be located so as to be at least partially overlapped by the transistor, and be electrically connected to the second capacitor electrode via a contact hole formed in an insulating film disposed between the second capacitor electrode and the light-shielding film.
