A write current is contracted without loss of precision of current-driven
structure. While a capacitance TFT is switched off, a data current is
supplied from a power supply line PVDD through a driver TFT and a
selection TFT to a data line DL. With this process, a voltage which is
lower than PVDD by an amount corresponding to a writing current of the
driver TFT is set to gate of the driver TFT. Then, a control TFT is
switched on so that a current corresponding to the gate voltage of the
driver TFT flows to an organic electroluminescence element. In this
process, the capacitance TFT is switched from an off state to an on state
so that the gate voltage of the driver TFT changes corresponding to the
change in capacitance and the drive current is contracted while the
threshold value and mobility of the driver TFT are compensated for.
