Electroluminescent device
First Claim
1. An electroluminescent device comprising in sequence a first electrode, a first luminescent layer provided on said first electrode, a second electrode, a second luminescent layer, and a third electrode, wherein each of said luminescent layers includes a first layer of an electron-accepting organic compound, a second layer of an electron-donating organic compound, wherein at least one of said first layer and said second layer in said first luminescent layer and said second luminescent layer is selected from the group consisting of a Langmuir-Blodgett monomolecular film or a built-up film thereof.
