Abstract: In a pixel circuit, during a period during which an organic EL element is not emitting light, transistors are in an “on” state and the organic EL element is reversed-biased by a low-level power-supply potential and a reverse-biasing power-supply potential. A reverse-direction voltage determined by a reverse-direction current that depends on the degree to which degradation of the organic EL element has progressed is thus written to a capacitor. A data voltage is then supplied to the capacitor via another capacitor, bringing the drive voltage of a transistor that controls the current that drives the organic EL element to Vsig+Voledr. This makes it possible to minimize decreases in the emission luminance of an electrooptical element such as an organic EL element due to degradation thereof over time.
