Abstract

Both directionality and intensity of emitted light from the organic electroluminescent (EL) device were strongly modified using a Fabry-Perot microcavity. The microcavity EL device exhibited a single mode emission that was significantly enhanced and the emission was sharply directed along the direction normal to the device surface. The luminous efficiency in the normal direction was much higher than that of the noncavity EL device. The sharply directed pure green emission exceeded 40000 cd/m² at a driving current of 800 mA/cm².
