A discharge transistor (TFT 3 ) which connects the upper end of an organic EL element (EL) and a negative power source (VEE) and a control transistor (TFT 4 ) which connects the upper end of a storage capacitor (SC) with a power source (PVDD) are provided. These transistors (TFT 3, TFT 4 ) are turned on by the upper gate line, so that the capacitor of the organic EL element (EL) is discharged prior to the selection of the line for these transistors.
