Abstract:
1. An electro-optical device comprising: a scanning line; a data line intersecting the scanning line; a pixel circuit provided corresponding to an intersection of the scanning line and the data line, the pixel circuit including an electro-optical element, a driving transistor controlling a current which flows through the electro-optical element, the driving transistor having a gate, and a switching transistor provided between the gate of the driving transistor and the data line; a power source line connected to the pixel circuit; a scanning line driving circuit outputting a scanning signal to the scanning line; a data line driving circuit outputting a data signal to the data line; and a power source line control transistor provided outside of the pixel circuit, wherein a voltage compensating a threshold of the driving transistor is supplied to the gate of the driving transistor while a driving voltage is supplied to the power source line based on an operation of the power source line control transistor.
