The driving circuit includes plural pixels each having a thin film transistor of which a threshold voltage reversibly changes due to the electrical stress applied between a gate terminal and a source terminal, and a voltage applying unit which sets gate potential of the thin film transistor higher than source potential. The voltage applying unit applies the electrical stress between the gate terminal and the source terminal at a time when the thin film transistor is not driven, so as to drive the thin film transistor in a region that the threshold voltage is saturated to the electrical stress.
