<p>A dispersion type EL element is provided which shows an excellent luminance and has an improved life. Further, a dispersion type EL element is provided which permits a large-sized panel, shows an excellent luminance and an excellent durability and has an improved life. A dispersion type electroluminescent element comprising a pair of electrodes one of which is a back electrode and the other of which is a transparent electrode and, disposed between the electrodes, at least an insulating layer and a luminescent-particle-containing luminescent layer, the luminescent particles having an average size of from 1 µm to less than 20 µm and a coefficient of variation of from 3% to less than 35%, and the element having a barrier layer containing at least one material selected from the group consisting of a thermoplastic resin, a thermoset resin and a Ultraviolet-cured resin between the transparent electrode and the luminescent layer.</p> |
