Abstract
One pixel () is comprised of a controlling TFT (Tr), a TFT (Tr) functioning as a threshold voltage generating element, a TFT (Tr) functioning as a reset element, a driving TFT (Tr), a capacitor (C) holding the gate voltage of the driving TFT, a TFT (Tr) functioning as a current restraining means for being controlled so as to be OFF at a reset operation time, and an EL element (E). At the reset operation time in which a terminal voltage of the capacitor (C) is reset to a predetermined electrical potential, a current restraining means comprising the TFT (Tr) is controlled so as to prevent excess current due to an operation of the driving TFT (Tr) from being imparted to the EL element (E).
