ABSTRACT:
Each pixel includes: a first wiring for allowing a current to flow to an organic EL element; a first TFT element, provided in series to the organic EL element so as to be positioned in a path for allowing the current to flow from the first wiring, which has a control terminal for controlling conductance of the first TFT element; a second TFT element, provided in series to the organic EL element and the first TFT element so as to be positioned in the path, which has a control terminal for allowing/disallowing conduction; a capacitor which applies a voltage corresponding to stored electric charge to the control terminal of the first TFT element as a control voltage for controlling the conductance of the first TFT element; a third TFT element, provided in a path for supplying the electric charge to the capacitor, which has a control terminal for allowing/disallowing conduction, said third TFT element causing the capacitor to store the electric charge by disallowing conduction; a second wiring which applies a control voltage to the control terminal of the second TFT element; and a third wiring which applies a control voltage to the control terminal of the third TFT element. Thus, it is possible to enlarge an area of a transparent electrode.
