El element

摘要

An EL element comprising: a light transmitting substrate (1); a light transmitting electrode layer (2) formed on the substrate; a light emitting layer(11) containing a positive ion exchanger; a dielectric layer (6); a back electrode layer (7); and a dielectric insulation layer (13) disposed between the light transmitting electrode layer and the light emitting layer. The dielectric insulation layer (13) is formed of a synthetic resin that is insoluble with a synthetic resin binder forming the light emitting layer (11). The present invention provides an EL element having an improved illuminating performance, where an occurrence of a dark spot is suppressed, in addition to a suppression of an occurrence of a black spot.
