Electronic circuit, driving method thereof, electro-optical device, and electronic apparatus

An electronic circuit comprising:

• a driving transistor for controlling a current flowing through a driven element;
• a first switching element turned on during a first period and turned off during second and third periods, between a gate and a drain of the driving transistor;
• a capacitive element one end of which is connected to the gate of the driving transistor;
• a second switching element at least turned on at a starting point of time of the first period and turned off during the second and third periods, between the other end of the capacitive element and the drain of the driving transistor;
• a third switching element for turning on between the other end of the capacitive element and a signal line to which a voltage corresponding to a current flowing into the driving device is applied during the second period;
• and
• a fourth switching element turned off during a first period and turned on during second and third periods, for cutting off the current flowing through the driven element when turned off, regardless of the control of the driving transistor.

An electro-optical apparatus having pixel circuits at intersections of scan lines and data lines, the scan lines being sequentially selected, and the data lines having applied thereto a voltage corresponding to a current flowing into an electro-optical element,

• wherein, each of the pixel circuits comprises:
• a driving transistor for controlling a current flowing through the electro-optical element;
• a first switching element turned on during a first period and turned off during second and third periods, between a gate and a drain of the driving transistor;
• a capacitive element one end of which is connected to the gate of the driving transistor;
• a second switching element at least turned on at a starting point of time of the first period and turned off during the second and third periods, between the other end of the capacitive element and the drain of the driving transistor;
• a third switching element turned on during the second period between the data line and the other end of the capacitive element;
• and
• a fourth switching element turned off during a first period and turned on during second and third periods, for cutting off the current flowing through the electro-optical element when turned off, regardless of the control of the driving transistor.
