    • An organic EL display apparatus has a driving circuit. In the driving circuit, the source and drain of a driving transistor and the anode and cathode of an organic EL device are connected in series between voltage sources. A current passes between the source and drain of the driving transistor and between the anode and cathode of the organic EL device in accordance with a voltage between the gate and source of the driving transistor. Consequently, the organic EL device emits light. In order to store the voltage in the capacitor, a constant voltage source is connected to the gate of the driving transistor and the above-described series connection is disconnected at the source of the driving transistor and connected to a signal source. Then, a current signal output from the signal source passes between the source and drain of the driving transistor, and charges are stored in a capacitor in accordance with the current signal.
