Abstract
In a display pixel of an element substrate of an electro-optical device, a first gate electrode of a first transistor is electrically connected to a scanning line via a first contact hole of an insulating film. In a dummy pixel, a light blocking layer of the same layer as the scanning line is formed, and a second gate electrode of a second transistor is electrically connected to a scanning line via a second contact hole. A gap between the end portion of the second contact hole and the end portion of the scanning line is wider than the gap between the end portion of the first contact hole and the end portion of the scanning line.
