Abstract

An electro-optical device includes a substrate, a transistor over the substrate, a pixel electrode over the transistor, a source line between the transistor and the pixel electrode, a fixed potential line over the substrate, a first capacitive element comprising a first electrode electrically connected to the fixed potential line, a first capacitance film, and a second electrode, a second capacitive element comprising the second electrode, a second capacitance film, and a third electrode electrically connected to the fixed potential line, a third capacitive element comprising the fixed potential line, a third capacitance film, and a fourth electrode. The first capacitive element and the second capacitive element are provided between the transistor and the source line, and the third capacitive element is provided between the source line and the pixel electrode.
