COMPOUND FOR ORGANIC ELECTROLUMINESCENT DEVICE AND ORGANIC ELECTROLUMINESCENT DEVICE USING THE SAME

摘要

Disclosed is an organic electroluminescent device (organic EL device) which has improved luminous efficiency, sufficient driving stability and a simple structure. The organic EL device comprises a light-emitting layer between an anode and a cathode arranged on a substrate, and the light-emitting layer contains a phosphorescent dopant and a host material composed of a compound represented by formula (1) which has a carbazolyl group at each end. In the formula (1), each X independently represents an optionally substituted CH or N, and each L represents a direct bond, an ethylene group or an acetylene group.
