Abstract
The present invention discloses an electroluminescent element comprising spherical spacer particles in a luminescent layer having a dielectric constant of not less than 10 at 1 KHz and 25.degree. C. and an insulator layer having a dielectric constant of not less than 10 at 1 KHz and 25.degree. C. which both layers are disposed between a transparent electrode and a back electrode, either of said luminescent layer or of said insulator layer having been produced by forming a phosphor paste layer or an insulative paste layer and solidifying each with radiation, respectively.
