1. A light emitting element, comprising:
a first electrode;
a second electrode facing the first electrode; and
a plurality of functional layers disposed between the first electrode and the second electrode, wherein
at least one functional layer among the plurality of functional layers comprises a monoamine compound comprising:
a phenanthryl group directly bonded to a nitrogen atom;
a dibenzoheterole group, that is a dibenzothiophene group directly bonded to the nitrogen atom at a 1-, 2-, 3-, or 4-position with respect to a sulfur atom thereof or a dibenzofuran group directly bonded to the nitrogen atom at a 1-, 3-, or 4-position with respect to an oxygen atom thereof; and
a naphthyl group bonded to the nitrogen atom via a linker,
the phenanthryl group is an unsubstituted phenanthryl group or a phenanthryl group substituted with a deuterium atom,
the naphthyl group is an unsubstituted naphthyl group, a naphthyl group substituted with a substituted or unsubstituted phenyl group, a naphthyl group substituted with a substituted or unsubstituted naphthyl group, or a naphthyl group substituted with a deuterium atom,
provided that when the naphthyl group is substituted with a substituted or unsubstituted phenyl group and when the naphthyl group is bonded to the linker at a 1-position, the substituted or unsubstituted phenyl group is not bonded to the naphthyl group at an 8-position, and
the dibenzoheterole group is substituted with at least one substituted or unsubstituted phenyl group.
