ABSTRACT:
An electro-optical device is provided having a pixel portion with a novel structure, and in which display irregularities such as crosstalk, which develop due to a drop in voltage caused by the wiring resistance of electric current supply lines in an electro-optical device, are improved upon. Attention is drawn to the fact that during a period in which write in of a signal to a pixel from a signal line is not performed, a signal is not input to a source signal line and to a gate signal line, but are at a fixed electric potential. An electric current supply line and a source signal line, or an electric current supply line and a gate signal line, are connected through a switching transistor. A signal is input to a connection control line during a sustain period, and the connection transistor is made conductive. The source signal line or the gate signal line is therefore utilized as a pathway for supplying electric current to the EL element.
