Abstract
An EL device includes a control unit that controls a driving circuit so that a plurality of EL elements emits light several times per driving cycle. Specifically, when a driving voltage is applied to the plurality of EL elements, the plurality of EL elements emits several times per driving cycle. As a result, since the amount of light integrated per time increases, the plurality of EL elements obtains high luminous power even if a plurality of El elements having a very short emission decay time is used.
