摘要： Provided is to a display element capable of displaying an image on both sides thereof. In the display element, display operation is not constantly performed on both sides, and the display operation is, as necessary, switched to displaying only on one side without lowering the efficiency of a backlight or other light emitting bodies. The structure is made such that a planar light emitting body capable of emitting light in directions of both faces is sandwiched between two light control elements capable of electrically switching, from outside, between a light reflection state and a light transmission state. In such a structure, the faces of the light control elements serving as light reflection surfaces in the light reflection state face the planar light emitting body, and the planar light emitting body and the light control elements are further sandwiched between two liquid crystal elements.

摘要： 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.
