Abstract
When the transistor Qis OFF, a predetermined potential is supplied to a potential wire Ui such that a switching transistor Qbecomes ON. This changes a gate potential of a driving transistor Qfrom an ON potential to a threshold potential. Thereafter, the transistor Qis turned OFF, with the result that the potential of the potential wire Ui is changed (in cases where the transistor Qis a p-type transistor, the potential is decreased). With this, the transistor Qallows a current to constantly flows therethrough, irrespective of the threshold potential. This shortens time for setting an output current of the driving TFT for driving a current driving type display element.
