Abstract

An electroluminescent element (1) includes an emission layer (4) inserted between a pair of electrodes (2, 5), said emission layer (4) contains phosphor. The amount of chloride ion eluted from the phosphor is not more than 10 ppm. The electroluminescent element (1) improves lifetime of the device and reduces power comsumption.
