NOVEL ORGANIC ELECTROLUMINESCENT COMPOUNDS AND ORGANIC ELECTROLUMINESCENT DEVICE COMPRISING THE SAME

摘要

The present invention relates to novel organic electroluminescent compounds and an organic electroluminescent device comprising the same. According to the present invention, the organic electroluminescent compounds improve current characteristic of the device, thereby lowering driving voltage of the device. A device including existing organic electroluminescent compounds needs a hole blocking layer. Though, the device including the organic electroluminescent compounds of the present invention does not need the hole blocking layer and improves lifespan.
