Abstract
An organic compound having a hole-transport property and a low refractive index is provided. An organic compound represented by General Formula (G1) shown below is provided. In General Formula (G1), Arrepresents a substituted or unsubstituted arylene group having 6 to 13 carbon atoms in a ring, n represents an integer of 0 or 1, and 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 in Aris more than or equal to 6. Rto Reach independently represent an alkyl group having 1 to 6 carbon atoms. Rto Rand Rto Reach independently represent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms. Any one of Rto Rand any one of Rto Reach represent a bond directly bonded to a nitrogen atom, and the others each independently represent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms.
