An electro-optical device includes a first data transfer line that intersects a scan line, a second data transfer line, a first transistor that controls coupling between the first data transfer line and the second transfer line. The two or more second data transfer lines are respectively coupled to the first data transfer line via first capacitors, and when a collection of pixel circuits that are coupled to the same first data transfer line via the second data transfer lines is referred to as a pixel string, the second data transfer lines are provided to pixel circuits less than the pixel circuits included in the pixel string.
