Organic electroluminescence device and photoelectron device using said electroluminescence device

A photoelectron device using an electroluminescence device, wherein the electroluminescence device comprises:

• 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;
• wherein 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.
