Document Type and Number:

Japanese Patent JP6637240

Kind Code:

B2

Abstract:

A light-emitting element with high emission efficiency. The light-emitting element includes a pair of electrodes and an EL layer between the pair of electrodes. In the light-emitting element, the EL layer contains at least a light-emitting material, the light-emitting material is a 1,6-bis(diphenylamino)pyrene derivative, and a structural change between an excited state and a ground state in the 1,6-bis(diphenylamino)pyrene derivative is smaller than that in a 1,6-bis(diphenylamino)pyrene derivative in which hydrogen is bonded to ortho positions of two phenyl groups of each of two diphenylamino groups.
