Patent ID: 8164549

Claim:
An electronic circuit that drives a driven element to which a driving voltage or a driving current is supplied, comprising: a signal line; a unit circuit connected to the signal line; and a voltage supply line, the unit circuit comprising: a driving transistor comprising a gate terminal, a first terminal, a second terminal connected to the voltage supply line, and a channel formed between the first terminal and the second terminal; a switching element that controls an electrical connection between the gate terminal of the driving transistor and one of the first terminal and the second terminal; and a capacitive element that includes a first electrode connected to the gate terminal of the driving transistor and a second electrode connected to the signal line, wherein a conductive state between the first terminal and the second terminal is controlled by a gate voltage applied to the gate terminal, a first signal is supplied to the signal line during a first period, and the switching element is changed from an off state to an on state, a second signal is supplied to the signal line during a second period after the first period, and the switching element in the on state is changed to an off state, from a period in which the first signal is supplied to the signal line through a period in which the second signal is supplied to the signal line, there is only one time that the switching element is placed into an on state, the first signal is a fixed voltage V 0 and the second signal is a data voltage V[i], and the fixed voltage V 0 is supplied prior to supply of each data voltage V[i] during the second period, and the fixed voltage V 0 is greater than said each data voltage V[i].
