The invention provides an electronic device that performs driving control of an electro-optical device by current driving at a high precision and reduces the number of components. The invention can include, along a data line to which pixel circuits are connected between a driving power source and a driver, a conversion transistor formed of a diode-connected transistor that is inserted between the driving power source and the pixel circuits. The conversion transistor can be used in common among the pixel circuits. Each pixel circuit can be formed of a driving transistor which forms a current mirror circuit with the conversion transistor, a control transistor driven by a scanning driver, for turning on and off the connection between the conversion transistor and the driving transistor, and a capacitive device for holding a voltage applied to the gate of the driving transistor by the control transistor. The driving transistor causes current corresponding to the voltage held by the capacitive device to flow into an organic electroluminescent device.
