Paper Abstract

Narrow beamed light emission was successfully obtained in a new type of organic electroluminescent (EL) diode whose organic layer was sandwiched between two metal layers acting as charge injecting electrodes and mirrors. EL from the organic film edge showed much sharper spectrum with a peak depending on the thickness of the organic layer and about 100 times larger emission density compared with that from the film surface of a conventional EL diode.
