Abstract
An electro-optical device includes a display portion, a data line driving circuit, a first retention capacitor that retains the potential of the data line, a driving control circuit, and a display control circuit that supplies brightness information to the driving control circuit and also supplies an image signal to the data line driving circuit. The data line driving circuit includes a potential control line to which a potential control signal is supplied, a third retention capacitor one end of which is connected with the data line and the other one of which is supplied with a potential based on the image signal, and a first transistor that is electrically connected between the other end of the third retention capacitor and the potential control line. The driving control circuit controls the potential of the potential control signal based on the brightness information.
