Organic electroluminescent device
First Claim
1. An organic electroluminescent device comprising:
- a first electrode;
a second electrode; and
an electroluminescent film containing an organic compound capable of causing an electroluminescence and being provided between the first electrode and the second electrode, wherein a carrier generation layer is embodied in the electroluminescent film, said carrier generation layer being a floating electrode;
wherein a first insulting film is provided between the first electrode and the electroluminescent film, said first insulting film preventing a carrier injection from the first electrode to the electroluminescent film; and
wherein a second insulating film is provided between the second electrode and the electroluminescent film, said second insulating film preventing a carrier injection from the second electrode to the electroluminescent film.
