Abstract

A novel organic compound that is effective in improving the element characteristics and reliability is provided. The organic compound, which is represented by General Formula (G1), has a structure in which a dibenzoquinazoline ring is bonded to a skeleton with a hole-transport property via one or more arylene groups. Any one of Rto Rin General Formula (G1) is bonded to any one of Rto Rin General Formula (G1-1). Note that n is any of 0 to 3; m is 1 or 2; A represents a single bond, or an arylene group; B represents a ring having a dibenzofuran skeleton, dibenzothiophene skeleton, or carbazole skeleton; and each of Rto Rindependently represents any of hydrogen, an alkyl group, a cycloalkyl group, and an aryl group.
