PURPOSE: To provide an electroluminescence element of excellent brightness and efficiency.

CONSTITUTION: A surface process layer including 0.1-10wt.% of palladium in a composition primarily composed of a resin of high dielectric constant, is formed into the thickness of 0.005-0.5μm between an emission layer and a transparent electrode layer, of an electroluminescence element comprising an electrode layer, an insulating layer, the emission layer, the transparent electrode layer, and a moistureproof film. The electroluminescence element is thus provided, in which the airtightness of the emission layer and of the transparent electrode layer is improved, and the efficiency is improved without lowering initial EL emission brightness, while the life span of which is improved.
