Claim:
A display device in which a driver transistor and an electro-optical element are directly connected between a power supply line and a common electrode, a first capacitor and a second capacitor are connected in series in this order between a gate terminal of the driver transistor and a node B, a first switching transistor is provided between the gate terminal of the driver transistor and a first line, a second switching transistor is provided between a second line and a node A, which is a node of the first capacitor and the second capacitor, and a current corresponding to an image signal is fed to the electro-optical element so that a corresponding image is displayed thereon, wherein the node B is a node of the driver transistor and the electro-optical element, Vcom is a voltage of a terminal opposite the node B out of two terminals of the electro-optical element, and Vth is a threshold voltage of the driver transistor, the display device comprising: an initialization section that performs initialization in which while Vcom is kept constant, a voltage Vs of the node B is set to be lower than Vcom if the node B is coupled to an anode of the electro-optical element, and the voltage Vs of the node B is set to be higher than Vcom if the node B is coupled to a cathode of the electro-optical element; a threshold correcting section that performs threshold correction in which data voltage as the image signal is applied from the first line to the gate terminal of the driver transistor, and a predetermined auxiliary voltage is applied from the second line to the node A under the condition where the initialization is performed, so that the gate-to-source voltage Vgs of the driver transistor is changed to Vth; and a signal control section that performs signal control in which a voltage for signal control is applied to the gate of the driver transistor under the condition where the threshold correction is performed, so that the gate-to-source voltage Vgs is changed to a value represented by a sum of the threshold voltage Vth and a value of a voltage corresponding to an image signal.
