Abstract

In an element substrate of a liquid crystal device, a peripheral electrode to which a potential Vtrap different from a common potential Vcom applied to a dummy pixel electrode and the like is applied is formed in a peripheral region which is interposed by an image display region and a sealing material. The peripheral electrode extends along the sealing material through the outside of the outside end of a data line driving circuit portion, and the outside end of a scanning line driving circuit portion, and does not intersect a data line and a scanning line.
