Abstract:
In an element substrate of a liquid crystal device, in a peripheral region interposed between an image display region and a seal material, a peripheral electrode to which a potential is applied for trapping ionic impurities which is different from a common potential applied to a dummy pixel electrode or the like is formed. In the peripheral electrode, an electrode width of a first portion opposing a sealing material provided at a liquid crystal injection opening of the seal material is set to be greater than electrode widths of the other portions.
