ABSTRACT:
By adopting the structure of this invention in which a transparent electrically conductive film is used in both of anode202A and cathode202B of an organic light emitting element having a hole transporting layer203, a light emitting layer204, an electron transporting layer205and an electron injecting layer206, providing films having a light reflecting function201and207on the outside of the anode and cathode, and thereby making the gap between them function as a light vibrator, there can be obtained an organic light emitting element with which the above-mentioned two problems can be solved simultaneously.
