摘要 |
By use of a 2,9,10-triaryl anthracene derivative in which a diarylamino-substituted aryl group is bonded to the 2-position of a 9,10-diarylanthracene for a light-emitting element, a light-emitting element having high efficiency can be obtained. The emission wavelength of the anthracene derivative is suitable for use in a white light-emitting element. By use of the anthracene derivative for a white light-emitting element, a white light-emitting element having high efficiency can be obtained.
