Abstract:
1. An electro-optical device, comprising: a substrate; pixel electrodes provided in a matrix above the substrate; a storage capacitor which is formed of a first capacitor electrode electrically connected to one of the pixel electrodes, a second capacitor electrode electrically connected to a fixed potential, and a dielectric film disposed between the first capacitor electrode and the second capacitor electrode, and which is disposed to correspond to the one of the pixel electrodes by using the second capacitor electrode as a capacitor line; a conductive pattern formed above the substrate; and a contact hole connecting the second capacitor electrode forming the storage capacitor to the conductive pattern, the second capacitor electrode being composed of an upper layer and a lower layer, the lower layer being formed before the contact hole is formed, and the upper layer being formed after the contact hole is formed.
