摘要:
The present invention relates to an organic electroluminescent (OEL) compound that comprises at least one fluorene derivative and at least one carbazole derivative. The compound has good electrical properties, light emitting properties and charge transport ability, and thus is suitable as a host material suitable for fluorescent and phosphorescent dopants of all colors including red, green, blue, white, etc., and as a charge transport material. An OEL display device that uses an organic layer that includes the OEL compound has a high efficiency, a low voltage, a high luminance, and a long lifespan because it has superior current density.
