Abstract
The strongly directed spontaneous emission along the optical axis of an organic electroluminescent (EL) diode with a typical emitting material, tris(8‐quinolinolato) aluminum, is realized with a planner microcavity structure. The structure of the microcavityEL diode is designed to have a resonance condition in which the total optical length is 3/2λ and the resonance wavelength λ is located at shorter wavelength side of a natural emission spectrum of a noncavity EL diode.Keywords
