Novel Organic Electroluminescent Compounds and Organic Electroluminescent Device Using The Same

摘要

The present invention relates to a novel organic electroluminescent compound and an organic electroluminescent device using the same. Said organic luminescent compound provides an organic electroluminescent device which has high luminous efficiency and a long operation lifetime and requires a low driving voltage improving power efficiency and power consumption.
