ABSTRACT:
An EL element comprising a light transmitting substrate, a light transmitting electrode formed on the substrate, a light emitting layer containing a positive ion absorber, a dielectric layer and a back electrode. Further, an EL element of the present invention contains a positive ion absorber in the dielectric layer. An EL element in accordance with an embodiment comprises a light emitting layer formed of a resin, a phosphor and a positive ion absorber, the positive ion absorber being 1-400 parts by weight to a 100 parts of the resin in the light emitting layer. An EL element in another embodiment comprises a dielectric layer formed of a resin, a high dielectric constant inorganic filler and a positive ion absorber, the positive ion absorber being 0.5-50 to a 100 parts of a total amounts of the resin and the filler.
