Abstract
A novel heterocyclic compound is provided. A highly efficient and reliable light-emitting element is provided. The heterocyclic compound is represented by a general formula (G1). In the general formula (G1), any one, two, or three of Yto Yin a ring A represent N atoms, and the rest of Yto Yrepresents CH. In the case where any two or three of the Yto Yare N atoms, the N atoms are not next to each other. Further, Arrepresents a substituted or unsubstituted biphenyldiyl group, Arrepresents a substituted or unsubstituted biphenyldiyl group, Czrepresents a substituted or unsubstituted heterocyclic group including a carbazole skeleton, Czrepresents a substituted or unsubstituted heterocyclic group including a carbazole skeleton, the carbazole skeleton included in the Czis directly bonded to the Ar, and the carbazole skeleton included in the Czis directly bonded to the Ar.
