摘要： A pixel circuit of an organic EL display includes a driving transistor for transmitting a driving current to an organic EL element. A first capacitor is connected between a gate and a source of the driving transistor, and a second capacitor is connected between the gate thereof and a boosting scan line. A voltage corresponding to a data current from a data line is stored in the first capacitor in response to a select signal from a selecting scan line. The voltage level of the boosting scan line is changed so that the voltage of the first capacitor is changed by coupling of the first and second capacitors. The driving current corresponding to the changed voltage flows to the organic EL element to emit light. As a result, the current flowing to the organic EL element can be controlled using a large data current, and the influence of the parasitic capacitance components of the transistors or data lines can be minimized.
