Abstract
An organic compound having a hole-transport property and a low refractive index is provided. An organic compound represented by General Formula (G1) is provided. In the formula, Arrepresents an aryl group having 6 to 10 carbon atoms in a ring and includes at least one branched-chain or cyclic alkyl group having 3 to 12 carbon atoms. The total number of carbon atoms of the branched-chain or cyclic alkyl group having 3 to 12 carbon atoms in Aris 6 to 36. Arand Areach represent a substituted or unsubstituted arylene group having 6 to 13 carbon atoms in a ring. Arrepresents a substituted or unsubstituted aryl group having 6 to 10 carbon atoms in a ring. In addition, n and m each independently represent an integer of 0 or 1. Arrepresents a phenyl group including at least one alkyl group having 1 to 6 carbon atoms. Arrepresents a phenyl group including at least one alkyl group having 1 to 6 carbon atoms, or an alkyl group having 1 to 4 carbon atoms.
