ORGANIC ELECTROLUMINESCENCE DEVICE

摘要

Disclosed is an organic electroluminescence device having a high brightness of 50 cd/m2 or more and a luminous efficiency of 0.02 lm/W or more, wherein an organic semiconductor zone and an organic insulator zone are sandwiched between electrodes, and the organic insulator zone contains an organic light emitting area, and the above organic semiconductor zone comprises electroconducting oligomer. Said organic electroluminescence device is capable of emitting light in the plane, shows a stable emission of light, and further can be prepared easily.
