Abstract
An organic electroluminescence device having a substrate, an electrode formed on the substrate, a light emitting layer formed on the electrode, the light emitting layer enabling injection of positive and negative electrical charges therein and an opposing electrode formed with respect to the light emitting layer so that the light emitting layer is arranged between the transparent electrode and the opposing electrode. The light emitting layer contains a light emitting substance for emitting light anisotropically, the light emitting substance having transition dipole moments attributable to a molecular skeleton thereof, and the transition dipole moments being oriented within an angular range from 0 degree to 70 degrees with respect to a direction normal to a side surface of the light emitting layer.
