Abstract
An electroluminescent device comprises a luminous layer containing electroluminescent particles each covered with a moisture-proof film, which is formed by polymer, having network structure obtained by hydrolyzing metal alkoxide and causing polycondensation reaction. The moisture-proof film may contain pigment, or a film containing pigment may be formed to cover the electroluminescent particle.
