Patent ID: 8643014

Claim:
An electro-optical device comprising: a substrate; a data line which is provided in a pixel region; a transistor which is electrically connected with the data line; a pixel electrode formed from a transparent conductive material which is positioned on a side of the substrate opposite to the data line so as to correspond to the transistor; a storage capacitance electrode which is provided in a layer between the pixel electrode and the data line so as to face the pixel electrode; a capacitance insulation film which is provided between the pixel electrode and the storage capacitance electrode; an additional capacitance which has a first capacitance electrode which is formed in the same layer as the pixel electrode and a second capacitance electrode which is formed in the same layer as the storage capacitance electrode and is electrically connected to the data line, and which is provided between the pixel region and a first side of the substrate; and a terminal which is provided between the pixel region and the first side, is electrically connected to the first capacitance electrode, and is formed in the same layer as the pixel electrode.
