A reduction in deterioration of a switching element over time in a current driving type emissive apparatus is realized. At the same time, a reduction in power consumption is realized. To this end, an AC voltage or an alternating current is applied between a source and a drain terminal of a switching element, and a DC voltage or a direct current is applied between a first and a second terminal of a luminescent element. This is realized by application of a voltage, which is inverted at predetermined intervals, to two luminescent elements heterogeneously arranged, to a luminescent element and a rectifier arranged in reverse orientation and in parallel, or to a full-wave rectification circuit. At this time, the rectifier is formed by a thin-film transistor, a PN junction, or a PIN junction, and is formed simultaneously with an existing switching element.
