Abstract

An organic compound has a benzonaphthofuran skeleton and is represented by General Formula (G1). In General Formula (G1), A represents a pyrene skeleton. In the case where the pyrene skeleton has a substituent, the substituent is a diarylamino group including two substituted or unsubstituted aryl groups each having 6 to 13 carbon atoms, a substituted or unsubstituted aryl group having 6 to 13 carbon atoms, an alkyl group having 1 to 7 carbon atoms, a substituted or unsubstituted monocyclic saturated hydrocarbon group having 3 to 20 carbon atoms, or a substituted or unsubstituted polycyclic saturated hydrocarbon group having 7 to 10 carbon atoms. The two aryl groups of the diarylamino group may be the same or different. In X1 represented by General Formula (G1-1), one of R6 and R7 is bonded to N in General Formula (G1), and the other of R6 and R7 represents an alkyl group having 1 to 7 carbon atoms, a substituted or unsubstituted monocyclic saturated hydrocarbon group having 3 to 20 carbon atoms, or a substituted or unsubstituted polycyclic saturated hydrocarbon group having 7 to 10 carbon atoms.
