Abstract
An electroluminescent device comprises a pair of electrodes and a luminescent layer sandwiched between the electrodes, the luminescent layer comprising: PA0 (a) one layer comprising a relatively electron-acceptable organic compound, PA0 (b) another layer containing a relatively electron-donative organic compound, and PA0 (c) still another layer having an insulating property, the three layers being repeatedly accumulated, and at least one of the three layers having a monomolecular film or a monomolecular layer built-up film.
