The display device of the invention comprises a plurality of scanning lines (Wscan and Escan) which are selected successively, a plurality of data lines (Data) to which the writing electric current (Idata) in accordance with brightness information is supplied according to the scanning line selection, and a plurality of pixels (PX) arranged at intersecting points between the scanning lines and the data lines. Each of the pixels comprises a light emitting element (OLED), a driving transistor (TFT 4 ), a capacitor (C) connected to the gate (Nd) of the driving transistor for accumulating writing data, a first transistor (TFT 1 ) which is turned on during writing period in which the scanning lines are scanned and which connects the data lines and the drain of the driving transistor, and a second transistor (TFT 2 ) which is turned on during the writing period and which short-circuits the gate and drain of the driving transistor. With such a structure, the light emitting element can be driven with a driving electric current equivalent to the writing electric current, irrespective of variations in characteristics of the transistors,
